Hello Is it possible to enable all the T-mobile US carrier features on the Exynos N960F/DS ?
Yes, when I reach 10 posts. I will be able to make a new thread with step by step images.
HERE is the guide, I got to 10 post

Is there absolutely any way to do it without root? Can't I take the home CSC of a desired rom and flash just that in Odin, keeping everything else as it originally was?

Not sure, I saw something like that on another post but then it was updated 4 pages later to say that method was not functioning. I assume you don't want to trip knox, but if you just don't want root but want custom CSC flash twrp and custom rom with root. Edit files to change csc as shown in my guide, or others guides. then factory reset rom, and reflash without root, and then make odin reset the recovery to stock recovery.
This is all speculation however.
I was very excited to see this as I've been wanting an international Exynos variant due to absolutely 'needing' to have root.
The Million dollar question is "Does the carrier aggregation still exist? ie... Does ALL the bands work perfectly on T-Mobiles network just as it would 1:1 on a TM variant Note 9?"
I along with some other fellow Note 8 owners got the (F) model of the Note 8 last year and we had discovered that the international variants on T-Mobile / US network suffered from carrier aggregation, where it would connect fine to one single frequency, but it would not aggregate properly to where it would not be able to 'hand off' / 'connect to multiple frequencies at once' with the (F) variants....
For those that remember, I went as far as completely disassembling my Note 8 and testing varies antenna cables thinking that it was hardware related, however, it has been concluded that it is a software issues that causes the international variant of the Note 8 to not work properly on US carriers....
Note: If one is in an area with good signal in the US with a (F) variant, it may look like everything is fine and well, however, it is not. Due to the good reception, the (F) variant is connecting only to that one band, whereas with other devices the domestic US variant would have the ability to pick up several bands and aggregate accordingly, where the (F) can't ...
Therefore, the Million dollar question is "Does this carrier aggregation issue still exist on the Note 9?"
The only way to be able to properly test this is for one to have both the T-Mobile Note 9 + the International (F) variant Note 9 and test the bands side by side in multiple areas ... along with checking in the hidden settings to see exactly what bands it is connected to. If they match, great.... if not, then the carrier aggregation still exists.....
While at it, I'll tag my fellow OG partners in Android Fanatics @DeeXii , @butchieboy , @KennyLG123 ....
I doubt it. It will probably be another year or two to get full or near full capability on Samsung modems. Look at all the weird spectrums going up in different countries. And TMobile just got band 71. It will be awhile before we start seeing noticeable effects nationwide for 71. Your optimism is obsessive. When the galaxy note 2 came out all were Exynos chipsets but some had LTE radios. I opted for without mainly because LTE was not fleshed out yet. (and the LTE radios were add on chips and not fully integrated meaning they were battery drainers). I made a good call as did Apple. You also have to consider Qualcomm has a lot more experience than Samsung and Intel in modems and radios. People are so focused on the results or what they can get without thinking through the whole front end of it and what is plausible, necessary and time needed. I am not saying no but again your optimism is obsessive to a fault. Qualcomm hasn't even made a truly international modem yet. (More bands than they can fit in their design and still too many different techs.) How would Samsung do it? It could be done but your battery life would suffer. That's why there are regional phones. Alsooooo, 2g bands are being deprecated in a few places (I think hspa too but nowhere near as much as GPRS/EDGE). To be honest I think it won't be until 2021 at the very least where there will be a few mainstream phones that you could pop in a sim anywhere and get good service across those regions. For now, you have to compromise. LTE is thankfully dropping in the GSM bucket but it needs to be sorted out.

Yes I remember that thread very well, kalm_traveller also made adjustments to the antenna . I recall that ultimately carrier aggregation didn't work on international models when used on the USA networks.

So how come Apple is doing that since the iPhone 6s unlocked version? Qualcomm Modem and a truly a word.
Doing what?
I would almost guarantee no ca working. Does it really matter? My s8+ still got 12mb download speeds.

I have the F model and tested with both AT&T and T-Mobile. Carrier aggregation works with 2 bands on AT&T (12+2) and while it supports all the other AT&T bands it will not aggregate them. No carrier aggregation at all on T-Mobile (single band only).
You can see the supported CA combos the F model has by looking at the FCC filing of the device (do a google search).

Doing a world phone with smaller battery than the Note line.
So basically it can be done. Samsung can make a world if they want to.
Apple doesn't have a world phone. They have a minimum of 2 phones to do the world. You have to pick your poison of which part. If they do have one, it probably has you covered for calls but not data. Heck any phone has this if data is less a priority and making calls and texts are a higher priority.
There might be obscure world phones but we probably are not privy to it. Satellite phones too of course but price. I actually read an article about Qualcomm's modem and the increase of LTE bands that came out recently talking about RF360 and Intel and Samsung probably not having anything to compete for at least a couple of years. They don't have an all in one solution yet. Close but not world yet. You have China, US and I forgot what part of South America that messes it up. Even though LTE falls under GSM standards I wish they would tighten it up. So many bands across different countries now and you can't keep up. Band 71 for TMobile is not relevant yet unless you live in a market that is getting it because of low or no coverage.

I think your lack of optimism is obsessive and at fault. What's wrong with being optimistic and having hope? Most of us are just wanting a simple root on the SD variant of the Note 9, whether it be a samfail method or whatever, we'll take it.
The US variant Note 5 was Exynos and worked just fine, so its not impossible for an Exynos equipped phone to work on US carriers. After all, most of the newer phones have a wide range of frequencies that it can support. Sure some phones are set regionally, but you're aware that there are dual SIM phones right?
If you were familiar with the F model Note 8 that some of us got and have tested last year, then my post would have made more sense to you.

Yes it does matter, because with out the ability for the phone to hand off and/or merge the signals, for those in areas where the reception is sketchy, it'd become major headache.

Hey @clubtech, thanks for reiterating. Yea that was the case exactly as you've described.... I was getting the same results on TM on the F variant. I'm aware of the fcc filings, but the curiosity stems from the potential possibility...
Is this a possible lead to get CA working on N960F/DS?

I tried using the dialer codes *#0011# and *#2263# first to get an idea of what I was looking at. These are mentioned further down in the Reddit thread by other users.
Apparently the code mentioned in the Reddit thread OP is a more advanced code that was removed/disabled from being activated from the dialer several iterations of Samsung devices ago...(ie. It now requires root, can only be activated from adb or terminal).
My theory is that Samsung has now fully gimped it or further hid the activation method. This method apparently worked on the Note 8...

Hey, I'm the author of that thread and I also have an Exynos s9+ which is same as the Note 9.
The menu is indeed completely disabled, you can't get to it even with adb or root.
There is a way to activate it, but it will not fix our issue. I've been trying for weeks.
We have a problem that started out on the Note 8, and that is the phone is not reporting the correct supported aggregation combos to the cell tower.
Using the menu, my phone does not support 4+12 however it reports 2+12 and I get carrier aggregation when I disable B4.
So far j haven't found a way to change those combos. At this point I'm very sure it grabs them from the CSC. I've been experimenting and have been unsuccessful so far
The S8 reported the correct combos out of the box, however the ill configured 3xCA was stopping it from working, disabling 3xCA made 2xCA work perfectly.
Our issue here is just were missing those combos so no matter what the phone will not do 4+12 even though the hardware is fully capable.
If anyone knows how to change combos, pm me or reply here, thanks.

I will totally donate to you if you can get this to work some how! It's pretty much the last feature I'm looking at as a "This phone is perfect except for X".

I have to say.... This is a bucket of **** (Aus Optus/Vodafone). I have half the 4g reception than my previous note 5.
It struggles switching frequency it seems. I hope future updates fix this and it's not a hardware issue.

I love the phone but noticed reception isn't as good in certain areas of North Carolina. I'm a T-Mobile user and also previously owned a Note 5. Definitely a difference.
Yeah mate...in places I had reception before I now have none.
I've noticed that my wife's phone will have 1 bar where mine has two, but if I go into settings and look at signal strength, it is exactly the same or even a little better.
Two note 8's had issues
Pre-ordered 1... nicest phone I've ever had until it started showing 'searching for service", ROAM, Emergency calls only... then would go to LTE with full bars, and back again. I went back to my S6 for two days with no problems, they sent me a second one... Fine for a day, then SAME ISSUES... did factory reset on both units... still persisted.. got LG V20 on special and full signal, every day....... Hope Samsung fixes issue and I will try one again.
---------- Post added at 10:54 AM ---------- Previous post was at 10:47 AM ----------
Signal strength is VERY important to me as I live way out in the sticks on the coast. The best reception on any mobile I have owned has been with the old Nokia's. The worst would be HTC. Samsung, LG, Asus, Motorola and Sony all work fine here. I am in part of the county that is notorious for very poor signal strength. I have not had a problem with my Note 8 seems to be fine on Vodafone but if I change to another supplier I get zero signal on all models of mobiles.
On times its not the phone brand but our service provider. My present provider for my TV and ADSL give me about 1Mbps!!!! that's if I get a signal at all. Vodafone hotspot gives me up to 30Mbps. Again it can be the provider more than the phone. I have found Samsung fine but others have not been so fortunate. I doubt its the Note 8 though? There are always lemons though in every brand.

which model of Note 8 are you guys experiencing this with?
Many of us Exynos owners have been noticing exceptionally poor reception and data speeds on USA carriers, but in my case I have narrowed it down to a hardware issue. Unplugging the lower antenna PCB has no effect on the poor signal strength, and this started suddenly after about 5 days of use. Out of the box it was amazing, and my download speeds were 30-50% faster than with the Note 5. I'm just waiting for replacement parts to become available so I can get a new board and replace it.

I thought the Snap Dragon version was issued in the States and China and the Exynos the rest of the world? PERHAPS the problem could be your carriers are not well suited to the Exynos models only the SD?
I am talking through my ears as I understand zero about such things. Here to learn. :good: Could also be one has purchased a lemon? I dont think its general to the Note 8, as I wrote above mine works very well here in a notoriously bad area of this country running Exynos.
Q; Is it wise to modify your mobile while it still has 12 months warranty? How many people have the skills to perform your modification and why should it be necessary? Your guarantee is now void.
Q; Out of the box you said it was amazing. What changed?

I'm no expert by any means, but I have the Note 5 from T-Mobile, which is also an Exynos device. The Exynos Note 8 is essentially just a newer Note 5, newer version of the CPU and modem (both have Shannon modems), and support T-Mobile's LTE bands. I do not believe there is any compatibility issue with the hardware. I definitely could have purchased a lemon, and that's what it seems like. The rest of the phones functions are amazing - it's literally just been issues with the components on that bottom PCB that have been popping up (not just for me, but also others on here, the lower circuit board has LTE antennae, mic, and lower speaker - all of which have had a few complaints of not working or not working properly).
To answer your Qs, my phone is a South Korean model and I live in the USA, so Samsung here will not honor the warranty. I would need to ship it back to Korea if anything. Many people have the skills necessary to replace this board, but it is a pain in the butt due to the rear glass using adhesive from Hades to stick to the frame. It shouldn't be necessary, but Samsung seems to have sent out some phones with faulty usb/antenna boards and it's less of a hassle for me to fix it myself than try to deal with international repairs.
Out of the box was amazing, I had equal LTE signal strength to my Note 5, and download speeds were about 4-6x what they suddenly dropped to after about 5 days of use. At the time, I thought it was due to flashing NEMESIS ROM, but I Odin flashed back to full stock and nothing was 'fixed' . Then, I opened the phone and found that physically applying pressure on one of the LTE antenna connectors in a specific direction made the signal strength jump up to equal my Note 5, and the super fast data speeds returned - as long as I kept pressure applied in that specific direction.

Excuse my ignorance,.but aren't there others on here complaining about LTE speed throughput on there F models also ? When using USA sim cards.
Perhaps it was a faulty batch?

You are correct, F and N models. They are the exact same hardware, and my thought is that a batch of those boards went out that have developed issues very quickly.
I read a post this week but can't find the thread now of course. In it, a user who worked on configuring phones for a large telco or something said that the antenna for each regional model is tuned to the particulars of that specific region. He wasn't just talking about supported bands, etc. It was really about antenna tuning. Ultimately he said this is why he decided to forgo the international Note 8 models in the U.S., even though he badly wanted an Exynos model for custom roms, etc. Now I personally don't know whether there is anything to his claims (and I wish I could find that thread again), but it made sense so I thought I'd mention it here as it could explain the LTE or signal issues. If it's bunk though, then please ignore

the bands are the frequencies that are 'tuned' for. Any given piece of metal is better at picking up certain frequencies than others, depending on how long it is, how thick it is, if there are any coils etc.
This is why region doesn't matter in and of itself - if a specific band is supported, the phone can operate with that band/frequency regardless of which country it was manufactured for. Where a person might run into problems is if their carrier uses a given LTE band or group of them and the international phone model they want does not support those bands.
In our case, the Exynos Note 8 has all the main bands we need for T-Mobile and AT&T here in the USA.
Is Note 9 model SM-N960F/DS (Dual Sim) fully compatible with T-Mobile?
Is there anything I need to know about this compatibility?
The N960F lacks support for LTE band 71 which T-Mobile US has been rolling out recently. It cannot properly aggregate US LTE bands so data speeds will be limited to the capacity of a single band. Out of the box the phone also cannot use T-Mobile's advanced services like VoLTE and Wi-Fi calling. Developer TEKHD has created a package called Detonator (link below) that installs the TMB CSC and makes other software tweaks to enable all the advanced services, essentially transforming the phone into an N960U variant, but you must be rooted to install the package. Rooting a Samsung phone permanently trips a hardware fuse which disables Samsung Pay and may prevent you from obtaining warranty service.

When stated that the TEKHD Detonator enables all the advanced services, does that include LTE Aggregation? Also, the link loads a non-existent site - is there another way to acquire TEKHD Detonator? Thanks for your time.

Has anyone done this? I very much would like to know. Currently with US variant phone, which I could turn back in for one of these if I only knew I could actually root it and still have T-Mobile's aggregation, etc.
I can actually answer this one with some real world experience. I bought my N960F in Germany, the dual sim Exynos model unlocked. I used it with Deutsche Telekom which is owned by T-Mobile and it worked just fine in Germany. When I returned to the U.S., I brought my phone back with me and started up a plan with T-Mobile because the Deutsche Telekom people advised me that it should work just fine. Lo and behold, it worked just fine except for WiFi calling at first. Weirdly, WiFi calling did eventually start working properly after a week or 2 which was great because my house is in a pretty bad cell coverage area. All I can remember doing to get it to work is keep messing with the settings and eventually it started working one day. My speeds are great on LTE, streaming HD Youtube and whatnot while I'm out so I can't say there is any issue with the LTE bands that I'm aware of.
It's worth noting that I rooted my phone and then unrooted it while I was in Germany, but I never changed to a custom ROM or anything so that probably didn't have any effect on the network compatibility. One issue I'm having now is that the phone does NOT work with Verizon, I just found that out yesterday. I'm sure someone knows the technical reasons for this but just know that you might be stuck with T-Mobile if you want to keep using the N960F in the U.S. But it does work! I can use hotspot, WiFi calling, and VoLTE as well.
Is the lack of band 71 a software or hardware difference? I thought it would be a hardware difference, as the 600 MHz frequency requires a longer antenna than higher frequencies. Or is it that all Note 9 have same hardware, where the differences are in disabling certain features?
There seem to be very slight radio differences. I don't know enough to know if buying the generic unlocked version will hinder my usage on T-Mobile. T-Mobile doesn't seem to be offering it for sale anymore. Is there a reason I might want the Exynos version in the U.S. if I don't travel? Any help would be appreciated.

All of the N960U and N960U1 devices are exactly the same. Literally.??
To use any of them on Tmobile and get the full tmobile features, just flash the T-Mobile version of the software for the N960U and you'll be good to go.
You can use the Exynos version but I am not sure if any of T-mobile's features would be hindered. Tekhd has a Detonator rom for the Exynos version to get it to run on Tmobile. I am assuming it will enable all Tmobile features. ??
no. every snapdragon galaxy device has the same hardware. If you buy a U version and you want it to be a T version, all you need is a computer, usb cable, drivers installed, Odin, some bubblegum to chew once youre done kicking ass, a keyboard, monitor and a mouse. Flash the T-Mob firmware, reboot and prepare to unwrap that bubblegum and the ass kicking will soon commence.
if you want root, get the xynos version, but if youre using GSM strictly, you wont notice a difference between the functionality of the F and U versions

Thats not exactly the case. The n960w (Canadian) has different cell band support than the n960u or n960u1. A slight hardware variation. I'm not entirely sure if you can convert a n960w to a n960u, but if you could, there would be missing or incompatible cellular bands. The phone would work, just not as well as a region specific device would.
I don't think so. If you are purchasing the US unlocked variant of the Note 9, you should be able to use it with any US cell provider. However you may have to take your device to a high street retail store and let them config some of the settings.

you should note the 2G and 3G bands being identical, or at least nearly and the screenshot you showed is suggesting these bands for LTE B38 – 2600 B39 – 1900 B40 – 2300 B41 – 2500

Short sighted much? Sprint and Verizon are both cdma carriers. So if anyone in the us on those carriers bought a n960w using your advice they would be lacking in cellular connection in some areas.
Not only that but you also completely ignored the 4g differences as well. Don't go around spreading false information like that. Just because it's snapdragon based doesn't mean they're the same.

Missing all the 3g-scdma and a few 4g bands would make quite a big difference, given that different 4g lte bands serve different purposes.
It goes to show that just because they are snapdragon based doesn't mean they are the same all I've done is prove my point that there are slight cellular band differences. Proved you wrong, deal with it and stop saying that all snapdragon note 9's are the same. You're wrong. All the n960u and n960u1's are the same but that's it.

this is hysterical.... ok dude.... theyre different because you say so. Oh, did you know that the single sim phones are also the same as the dual sim?
samsung made a very concerted effort to consolidate all of their physical models starting with the S8.
When canada came-a-callin, they must have changed their entire business model regarding the building of phones and the countries respective CSC's and threw them all out the window. So yes, let the poor suckers who took the advice of myself and many others suffer the consequences and wrath of having "the wrong phone".
Get a 960U and a 960W, put the sim card in each of them, prove that youre right or wrong, post up your findings and we can go from there. Until then, we have to base what we do on what we know. Techwalls says they dont share the same band connectivity, samsung says that theyre all the same. Do with that information what you will. Good day sir.

You are right, this is hysterical. Why do you think inserting a different Sim would tell us if the bands are available or not? It wouldn't. It's even funnier because your source wasn't Samsung. Do you have a link from Samsung showing all the bands being the same? I'd like to really see that one because currently you're wrong.
I'd really like to see how you're going to explain how the n960f and the n960u are the same phone?! do tell us how a exynos based phone and a Snapdragon Basedphone are the same thing hardware wise?!?!?! Not even talking about cell radios at that point, just the chipset itself?

omfg dude... the xynos F variants and the snapdragon (too many letters to bother listing) arent the same. The statement i made about them all being the same was assuming that you could go ahead with the already understood part of this discourse which is that we are discussing American continent versions. If youd like we could also discuss the Chinese versions that have snapdragon processors but are rootable. Thats not likely a rabbit hole you want to go down. I even just got off a chat with a rogers cellular tech who said that they are all the same phone. Every samsung s series or note series phone that was built for the americas are all the same hardware.
youre still wrong and youre fighting like hell to defend your losing position
oh, and for the info from samsung.....
i sold samsung phones at the end of the S7 lifespan and thru the S8 and S9s debuts. We got TONS of technical data on them at the time. Yes i perused the materials because it was such an unprecedented change in samsung phone lineup for the previous 7 iterations. FFS, ive flashed the G960F firmware on my G960U. Currently Running the G960U1.
And yes, putting your card in my phone and running a Cellular utility will tell you ABSOLUTELY what bands its using. Give up dude... Go read some more. Go to a cellular store and ask for the technical releases. THEYRE THE SAME PHONE

just because this is fun shutting you down. I did get my information from Samsung. I even got some demo models of the S7 and S7 edge from my local Samsung rep. I talked with him a lot. I sent him away to speak with his contacts in Korea about technical issues we encountered with various Sammy devices a few times for that matter.
Ive grabbed at&t S8s and activated them on Verizon. Theyre literally all the same. Im even beginning to think that the firmware is like windows. Every ISO of windows has every version built in to it, its just been bottlenecked to only allow installs of a certain version. Id be willing to entertain the thought of the firmwares doing the same thing. I say this because ive seen apps magically appear that were verizon specific on at&t phones when activated even before having data working or wifi
@troll and Doofus. You're both making schoolboy mistakes when attempting to compare radios on the W and U models.
Get the radio information from Samsung USA website and Samsung CA website then post your screenshots.
Besides, we all already know what F and W stands for in these models.[emoji1787]

from the guy complaining about not posting screenshots from samsung directly, its ironic that you havent posted them either.
oh, and yeah.... gsmarena is a non reputable site, i can see your reticence in accepting what they say as having any truth to it....
Please someone tell me if they've tested it yet. CDMA isn't a requirement anymore so should work?
It has to have band 12 for Verizon.
Sorry for the thread necromancy, but there are very few decent replies to this question, so I figured I'd answer it as thoroughly as possible from my own experience.
I imported an SM-N960F (Exynos) from the UK to use on Verizon, and I can tell you with certainty: on the stock rom, it's a plug-and-play experience. Just about everything works without hassle. You may have to look at the APN settings and manually select "VZWINTERNET," but mine auto-selected the right one out of the box. Phone calls work without issue using VoLTE. Same for data. I've noticed that it often tunes to different LTE bands than my old SM-N960U Snapdragon did, and it doesn't seem to do carrier aggregation as often, but the real-world speeds are just about the same between the two. If you live in an urban area with many different bands available, you might see slightly lower data speeds from the Exynos model, but I doubt it'll ultimately make much day-to-day difference.
All the other ancillary features work too, like Samsung Pay and the other Knox apps, as well as tethering and Google Pay, etc. The only thing that doesn't seem to work on Exynos that did work on Snapdragon is wifi calling; I see no option for it in the dialer app. I just use Google Voice in such situations, but if you rely on that feature...be warned, I guess.
Overall, though, I see no reason why anyone should buy a US-variant phone for use on Verizon any more. With the sunsetting of CDMA, it's pretty clear that international devices with unlocked bootloaders will work perfectly fine going forward. I plan to put custom roms on mine, and continue using my Note 9, with its headphone jack, iris scanner, and notch-less display, for as long as the community continues to support it.
As a final note: one thing I have noticed is that many roms for the Exynos Note 9 mention that VoLTE isn't supported, due to a proprietary Samsung implementation on these phones. This might present a problem to Verizon users, given that that's the only real way to make phone calls on these devices. Again, I tend to use Google Voice for almost all of my telephony needs...but if you're buying this phone for custom rom-ing purposes as I did, it's something to keep in mind.
Long time lurker, first time poster here. First of all, a massive THANK YOU to everyone here. You guys and gals are Awesome! <3
So, I bought a Samsung S10 (SM-G973F/DS) on Ebay recently and flashed it to Lineage OS 19.1. All was fine until I tried to activate it. We did everything...manually changing the ASP settings, and a bunch of other stuff to try and get this thing to connect to the mobile network. Even placed the SIM card in another phone just to confirm the SIM card was fine, which it was.
Long story short, I think the device was perhaps locked even though the seller claimed it was unlocked. Whatever, I'm over it. I flashed stock back on it and re-locked the boot loader, sent it back. Not worth the aggravation. However, I am questioning if there wasn't something else I could have done?
I was trying to activate the S10 on Mint Mobile USA (a T-Mobile reseller, so GSM) it should have been fine. The default language on the device was German. I don't think that should matter, but maybe it does? Do European phones have problems activating in North America?
My question is: If I decide to get another S10 (SM-G973F/DS) from the secondary market (if its even worth it at this point, since the SM-G973F/DS is really hard to find), is there anything I can find out from the seller first so I don't end up having to send it back?
Or, should I just give up my dream of having an S10 installed with Lineage OS and it's glorious headphone jack and expandable storage forever? If so, are there any worthy alternatives to the S10 worth considering, given my affinity for headphone jacks and expandable storage?
Hello PhonePerfection, all a novel why you speak S10 G973F / DS in the United States.
Already your model S10 G973F/DS exynos 5G or the first 4G model so if these this Europe chip model, if now installed Samsung phone info look at who is scoring at worst take screenshots.
I don't understand your question United States, locked unlocked the seller.
You buy in the back market refurbished and unlocked telephone all operator therefore for sim card, the concern these the chip to install network either US or ASIA controls your model if these good SM-G973F/DS and not SM-G973U or G973U1.
Don't forget to say hello
I think what @meric57 is trying to say is that your phone doesn't have the right chips to communicate on the frequencies in the USA. It's made for other markets and other frequencies... so it won't work here.
If you use FrequencyCheck you can see what carriers support what frequencies on your specific model: https://www.frequencycheck.com/comp...m-td-lte-512gb-samsung-beyond-1/united-states
Scroll down to the "United States" area and you'll see it doesn't support the frequencies used in the USA (except for GSM 2.5, which is old and dead here in the USA). The US is primarily on LTE... and you can see that phone model doesn't support ANY of the available frequencies.
Bottom line "GSM" doesn't tell you enough. You have an incomatible phone model for the USA market. No SIM card will fix that.
Note, in SOME cases, you can activate other frequencies by loading different ROMs into the phone. My old LG V30 did this, for example. I have heard that you can run some Exynos phones here in the USA, but I don't know the details to help. FrequencyCheck may help you figure that out. Be sure the look for the complete model number, not just "Galaxy S10" or something... the naming is worthless for figuring this out.

Hey, this is great info. Good to know. It looks like that S10 could only communicate on 1 of 8 bands used by Mint/T-Mobile. That 1 usable band appears to have been deprecated by T-Mobile as it is. I think that explains it perfectly. Thank You!
You're welcome.
Yeah, frequencies/bands are very important to watch, particularly if you're buying out of market devices. You have to know model numbers and carriers to be sure of anything, and unfortunately this info is relatively hidden.

The CSC on that device was DBT (Germany). I had to find that out in order to put the correct stock OS back on there.
Makes me wonder if the ebay seller even knows this. They appear to specialize in mobile phones with tens of thousands of transactions, so I would hope they've encountered this situation before. They were more than happy to accept a return on the device. Sent me a prepaid shipping label immediately.
Back to the CSC... Let's say I look for another S10 (SM-G973F/DS) but I ask what the CSC is for that device. Are there any regions outside the lower 48 states with reasonably good chances of it working? I suppose I would need to study the mobile frequency website for the answer to that.
I did some quick searching, and supposedly there are websites that say the 973F/DS will work on MM (mint mobile)... but they don't detail how. For example: https://de-googled.com/blogs/news/a-word-on-network-compatibility-of-our-degoogled-phones
and https://www.ebay.com/p/15030406771 (in the description).
So, maybe it is possible? I don't know, so maybe someone else can chime in.
Personally, I stuck with U-version phones and gave up rooting/romming. It's just getting too hard to find phones that offer this, so I figured I'd just adapt back to a stock ROM, since choices are limited. I had done a bunch of that in the past, but I found that stock roms (today) are pretty good... and allow enough customization that made root/rom unnecessary... for me. My current is an SM-G975U1 (unlocked, USA, Snapdragon S10+) on Total Wireless (VZ MVNO)... it works great and I don't miss root/rom at all.
Rumor is that the Galaxy S23 will only be offered as Snapdragon, so maybe that will open up more options... but I doubt it. Samsung loves it's Knox system, and will likely lock down the phone even more with every generation.

I did some quick searching, and supposedly there are websites that say the 973F/DS will work on MM (mint mobile)... but they don't detail how. For example: https://de-googled.com/blogs/news/a-word-on-network-compatibility-of-our-degoogled-phones
and https://www.ebay.com/p/15030406771 (in the description).
So, maybe it is possible? I don't know, so maybe someone else can chime in.
Personally, I stuck with U-version phones and gave up rooting/romming. It's just getting too hard to find phones that offer this, so I figured I'd just adapt back to a stock ROM, since choices are limited. I had done a bunch of that in the past, but I found that stock roms (today) are pretty good... and allow enough customization that made root/rom unnecessary... for me. My current is an SM-G975U1 (unlocked, USA, Snapdragon S10+) on Total Wireless (VZ MVNO)... it works great and I don't miss root/rom at all.

Thanks for the link. I think I may try for an S10 again if the seller can tell me what the CSC is. That page on De-googled.com affirms that American devices are more restrictive than their European counterparts.
It just doesn't make any sense to me personally to use a device with an open source OS that has loads of telemetry, spyware, bloat, etc. Which is a contradiction that I am not comfortable with. It's like installing a Linux distro that comes bundled with Facebook.
To me, being proactive about privacy is the equivalent to standing up for yourself in the real world. Sure, you can use a stock ROM and there is nothing wrong with that. It's having the freedom to choose which is most important. So long as that choice is available, I will happily go that route.
I like the added bonus of an Android device that seems faster with a longer lasting battery as well. I mean, I paid for this device. I should have the right to decide what apps are running on it.
No argument there... I agree with why we should be allowed to root/rom. Unfortunately, the carriers pull the strings in the USA (business over people) so we are losing options. Frankly, it pisses me off that they can still prevent phones from connecting to their network just because the IMEI doesn't match (even if the software is correct). In the end, if the device CAN work on the network, the carrier should have no say in allowing/disallowing it on the network. They like to claim that a "bad" device could "hurt" the network, but if that happens, they can lock out that phone and figure it out. I doubt that's even ever happened, but whatever. (They prevented me from using my already-working V30 US998 phone on the network, even though it ran as VS996 with no issues for years... they only later saw the IMEI wasn't "theirs" (original SIM card failed) so they prevented me from re-registering it. So stupid.)
Good luck, and let us know if you figure it out... I'm always curious to learn!
yes, most japan and europe phones do not have the correct radios channels in them for 4g and 5g. i ran into this same problem with my xperia phones that i bought overseas. this is a common problem that can happen.
The S10 and all it's variants is a world compatible GSM phone. So yes, the F variant should work with most GSM carriers and resellers in N. America.
There are various websites that will tell you what frequencies and carriers any particular model will work with if you do a search. Like this one.
WillMyPhoneWork.net - Check if your phone works on a network
Check 2G, 3G, and 4G LTE Network Frequency Compatibility for a Smartphone, Tablet, and Mobile Device in any Country and Mobile Network Carrier

According to that site the SM-G973F/DS supports all 2G, 3G, and 4G frequencies used by Mint.
