N950N Note 8 256GB working on at&t

SO I picked up a 256GB emperor edition from Korea. It is Confirmed to have every single LTE band that AT&T uses. I put my sim in and only get 3G not 4G. Called at&t and they said they need to re-appropriate the IMEI for the USA as it comes up as a 2g/3g phone because the SKoren SK telecom IMEI assigned to the phone is different in the USA. IS that True? Anyone know how and if I can get the Phone to work on 4G LTE on at&t or do I have to hope they get it right? I paid $1400 for this phone I don't want to use a 64GB version I have been waiting to have 500+ GB on a phone for so long.. Any TIps? Hints? Recommendations?
EDIT: for those reading this thread for the first time. As of 10/9/17 I was able to get good LTE speeds as well as WIFI calling and Video Calling on my N950N note 8 Korean Exynos model. In a nutshell here is what I did to make it work.
Flash nemesis n950F rom to my phone.
Flash AT&T CSC to the phone using the CSC tool and you do have to modify one line (user RED FLAME) has this in the CSC thread.
Call at&t and give them the IMEI of a VOLTE wifi calling/video calling capable cellphone (I used my wifes S8+ - and yes you can DOUBLE USE IMEI on the same account)
I also did one other thing - Check page 14 for that information.
I just wanted to give a synopsis of this thread so new N950N and at&t owners don't feel like they are wasting their time searching XDA and google. I only wish other people did this when their problem is solved so people can easily see they are not in the wrong place and don't have to read tons of pages of stuff.

Hi.
There is a thread somewhere here they were talking about similar problems.
What you where told is essentially correct. Though they also said that they needed a new sim card, too.
Hope this helps. Still waiting for my Note 8.

Too bad those devices do not have the CDMA bands...

I have the same model and same problem but with softbank, though softbank has been less helpful.. i read someone flashing a different csc (if its the right one) will "unblock" the phone? Would any exymos model csc work?
My roaming menu is also greyed out... not sure if that is related.

I think you just need to give them the IMEI and have them set it up for LTE in their system, since they don't by default allow LTE on bring your own devices.

Did you change the apn? I have the same phone on tmobile and i changed the apn to the tmobile apn and i have no problems with the phone.

Just a quick comment - I think you mis-spoke. ATT Does allow LTE on Bring your own devices. I have been using G955F variants for the last 4 years and never had to do anything other than put the SIM card in for it to work. HOwever, LTE Enhanced Services are not available on Bring your own Devices. This includes HD Calling, Wifi Calling and Video Calling. BUT, LTE will work.
I don't know anything about the Korean Model so I hope the OP is able to get things straightened out - but other variants have always worked on ATT - including TMOBILE PHONES and international variants as well.

That's probably what I meant. I haven't been an AT&T customer for many years, and have been with T-mobile for all my smart phone career, and they don't require any special setup on their end for VoLTE, Wi-Fi calling, etc as I can confirm with my Korean Note 8. After somewhat jankily switching CSCs with a modified script that was originally made for S8 and 8+ phones I definitely have VoLTE and probably have Wi-Fi calling working without any communication to T-mobile.

Waiting on at&t now.. to see what happens.. SPEC for SPEC this phone is exactly the same as an at&t phone. It has every single band, not missing a single one. If you put the specs side by side there is ZERO difference. I changed the APN - there are 3 at&t choices. One gives me 3G the other 2 do not work. SO waiting on at&t to re-appropriate the IMEI to register as a note 8 on their network. I had not idea it was going to be this much of a pain in the arse. I was told by a few sellers, pop in your sim and your good to go. I did need a new sim since my note 4 sim did not fit in the note 8, so They gave me a new sim. I put the sim (using an adapter) back into my Note 4 until they change over the IMEI and the new sim works just fine on the note 4 - all my video calling, wifi calling and tethering work fine. So hoping I do not need to return this phone and use a 64GB model. I wish samsung would just release the 256 here on at&t like apple is doing with the iphone X. I would pay $1200 for it no problem. (and since the iphone X is $1149 with 256gb - I am sure samsung would do $999 or $1099 to undercut apple. But Samsung is going to epic fail and never give the US customers what they want.

Hi there, I would also like to have the Emperor's edition, and use it in Canada (Bell) and USA (T-Mobile or AT&T). Is N950N the correct model number for this edition? Does it come with dual sim? Thanks! So far I found an Ebay seller from Hong Kong with F950FD which looks to be 256GB Duos - I'm wondering what the difference is with N950N and whether I will have an issue with region lock?
Thanks for any comments...

No, I was using it on a HTC10 and previously on a Note 4...

Totally DIsappointed... No way I am keeping this $1300 phone for how crappy it is on At&T.
They Finally Updated the IMEI so that is shows up as a next gen smartphone on at&t network and I get an LTE logo. I set my own ACCESS POINT as well as used all 3 that showed up automatically. ATT Phone, ATT NEXTGENPHONE and ATT UTDATA (Nextgen) + I did what was recommended on att.com for bringing over a phone that might not get the access point which was the same settings as ATT Phone - all of them gave me LTE on my bar and showed AT&T as the network. Every single LTE Band on this phone is the same as the official ATT note 8. Yet on my speed test I couldn't get better than 4MB/s down and 1.56MB/s up, my note 4 (pop the sim card back in there) even with 1 Bar on my phone I get 42MB/s download and like 10MB/s Upload.
IT is too late to call at&t tonight but I am extremely disappointed. I have wanted a phone with 256GB of memory for like 2 years now, and to have MicroSD expansion for just MUSIC (NOTHING ELSE).
If At&t can't get this note 8 to perform exactly like a at&t version would, then I either going back to my Note 4 or Perhaps the US Samsung unlocked version (which I already have but is not opened as I hoped to sell it and make a few hundred on it to make up for the $1300 I spent on this Emperor Edition.
Any advice?
Anyone want to buy it.. I paid $1299.99 Shipped from NK. Instead of returning it - if anyone wants to buy it, id do the same thing $1299.99 shipped anywhere in US or Canada. Perhaps it will work better on another network...

Does your unlocked version work as it should.. FAST LTE 4G LTE? Does your WIFI and Video Calling work?

tl;dr - Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working.
more detail on how i got VoLTE and HD Voice working.... i grabbed an ATT (Snapdragon) S8+ CSC and manually applied to the FE. To get HDVoice and VoLTE working, i called ATT and told them i was going to use my (no-longer used/retired) ATT Samsung S7Active with my cell number. this step was a must to get VoLTE working. once they associated S7Active IMEI with my cell number, i rebooted the Note FE and VoLTE was active. i occasionally receive calls and the HD Voice icon appears on the dialer screen; i assume the other person is calling me via Wifi when i see the icon. Video calling and Wifi calling haven't worked for me on none of my international devices. once i got my UK note 8, i applied the same CSC content (after rooting my device), i inserted the same ATT sim used in the Note FE, reset network settings and VoLTE and HD Voice (when receiving calls) still works.

I don't know about the Korean model, but here is how you get Volte on ATT on the Note 8 F model. https://forum.xda-developers.com/showpost.php?p=73851525&postcount=308 After you slightly modify the zip and flash this, you must call ATT and give the friendly customer service person the IMEI of a phone purchased from ATT directly that is roughly equivalent and had Volte and wifi calling features. I used an old S7. ATT will NOT accept an IMEI of any phone not sold by ATT. Once they put it into their system, reboot your Note 8 and whala - wifi calling and Volte work perfectly.

Kind of a NOOB when it comes to all this. I haven't flashed or done any phone hacking in a few years (my s4 was the last phone I really played with).
SO I downloaded the CSC Selection V1.2.1 on Android Filehost
I honestly do not know what to do from here.
Thanks.

Unlocked Bands and the Snapdragon 835

So I was thinking about current carriers and of course mvno's. (Currently on at t USA)
Theoretically the unlocked version of Snapdragon 835 has a lot of different bands it can use. Works fine on at t for me.
I am curious though, would some mnvo like net10 (access to multiple carriers) be able to uniquely take advantage of all the available lte bands that it can use )ex at t and TMobile depending on which has better speed or even use both?
Or does it not work that way. Does anyone have more knowledge then I do here?
Does anyone have experience with mvno's and how they work. I always shied away from them assuming they get secondary bandwidth compared to primary at t Verizon etc users.

I don't know what you mean. All OnePlus 5's are unlocked, They only difference is international or a Chinese variant. This means none are carrier locked but they only have GSM radios so they only work on AT&T or T-Mobile with LTE data. So whatever MVNO you use, has to be a T-Mobile or AT&T MVNO. The Bands are all unlocked it's just what band the carrier uses will it take advantage of from the MVNO.

that is partly incorrect there was some videos of a few well known reviewers in the android community that tested the oneplus 5 on verizon and it works .....including data.

No not incorrect at all. I said they only work on AT&T T-Mobile with LTE data. The Verizon thing you're talking about is 3G and less. What I said, it's 100% correct

On that note, there is only a single global version of the OnePlus 5. No Chinese only version.
Supporting the comments about Verizon though; it does work, but like you said, not well with data. Though the phone does support a single CDMA band. More useful for emergency calls than actually putting a SIM in it.

Same hardware though. So yes, again, technically correct that there is a version with a different OS but not correct that they have different support for bands. Which is what we're talking about.
Which is probably what you meant, just wasn't very clear.

So only some MVNO's have speeds limited by the big carriers. Others are treated identically. My wife is on cricket (ATT network, $35/month), her data speeds are capped at 10 Mbps (which is fine for her). I'm on straight talk (ATT network, $45/month) and my data speeds are identical to regular ATT customers (and I've confirmed by doing speedtest.net tests with a friend's phone side by side).
T-Mobile and Sprint coverage stink near me, and Verizon really limits what phones you can get, so I've stuck with ATT MVNO's over the years (been on straight talk since 2012). For heavy data users, straight talk has an 8gb data, unlimited talk/text for $45/month. If you don't need 8gb and you don't stream video/tether, you'd be better off on cricket, which is $35/month for 3gb+unlimited talk/text. Cricket also has dope family plans (5 lines for $100).
Be warned, straight talk customer service is awful. The only time you ever really need to call them is if you want to port your number over or if you forget to pay your bill (or your auto pay card expires or something). They can do simple stuff, but it's often like talking to a brick wall. Cricket customer service is MUCH better and if you don't need the extra speed, cricket is the way to go.
I have no affiliation with either cricket or straight talk, they've never paid me a dime to say anything nice about them, I'm just a very happy customer.
Sorry for the wall of text. Hope this helps some of you make the leap!

Unlocked Note 9 (SM-N960U1) on Verizon overseas

I just bought the SM-N960U1, an unlocked Note 9 (Snapdragon version) directly from Samsung (well, Best Buy, but basically Samsung). I have Verizon service. If I get Verizon's international calling plan, will I be able to use the Verizon service with my number on this phone in South Korea, or anywhere internationally? I already called and asked Verizon; they said it would be compatible, and their site states that voice, data, LTE, everything will work. The only thing I'm worried about is that I read this post which says it DOESN'T work.

Can anyone confirm that the SM-N960U1 with Verizon service will work overseas (specifically South Korea) on Verizon's international plan?
Thanks so much!

Your number will be the same, but I highly advise against paying for Verizon's stupidly expensive international plans. I have the same phone and service, and will be going overseas at the end of this month to Japan and Thailand. I bought myself a Google Fi sim card to use as it seems to be the most convenient and cheaper plan for me to use as it will keep the same number given while charging 20 cents a minute for calls (which I won't do), but let's me text for free and data costs the same as it would be here in the States. You should look into that instead.

That's awesome; thanks so much for the reply. Yeah, their international plans are a bit expensive I must admit. AT&T's, while not too much better, worked flawlessly while I was in Korea, so that was good.
I'll definitely look into the Google Fi. Are you going to simply forward your number to the Fi service while you are abroad?

Nah, I'll just create a new number so that way I don't get called by mistake. Especially robocallers.

The only issue I had with Google Fi when I had the service was that it wouldn't allow talk and data at the same time if connected to Sprint.

The Pixel 5 WILL have ALL Versions of 5G at Launch (in the U.S. at least)

So I just confirmed with Google themselves (both a customer service rep AND her supervisor) that the unlocked Pixel 5 WILL have ALL versions of 5G at launch in the U.S., not just Sub-6. It says "coming soon", but this only refers to the fact that not every city has mmWave in T-Mobile's network just yet (only 6 cities do, so far). It's misleading, and I let them know they should change that. So then I am sure that the Verizon version will have Sub-6 at launch as well after finding all that out.
This chart gives more details. I would HIGHLY ADVISE ignoring the "coming soon" parts. Just make sure your carrier offers 5G and that it's CURRENTLY available in your area. Me for example, I'm in the Chicago area. While Verizon has 5G (in downtown, of course lol), T-Mobile doesn't...........YET.
It's nice to know that the Pixel 5 will offer FULL 5G (aka, all THREE versions) at launch, where its main competitors do not.

Still waiting to find out if Spectrum mobile will allow the P5 on its network. Got no answers yet.

Is a new SIM required?

Since the 5 will have eSIM available, I'm going to activate that for the first time ever via my carrier (T-Mobile). Won't miss having to deal with a SIM card anymore. lol

Question Samsung ultra 21 Global or US version to purchase for rooting and AT

If I were to buy a Samsung 21 global version for rooting will it work with At&t network out of the box or should I just go for the US version and pay the money to get it unlocked if it is still possible. Also, does any one have any good links to get the global SM-G988b version of phone?
Edit: Accidentally hit enter when editing title.

AT&T has this whole whitelisting of the devices on their network for all features (like WiFi calling) to work. Better to buy a US unlocked variant. In the past, it has been possible to root Samsung US flagship versions.

Ah ok. I never cared about things like WIFI calling. I just wanted to still be able to make phone calls and get internet. Thanks for the info though. I still prefer the Global one if it works in the USA and so just wnateed to know if it will work in the usa.

If you look at the bands, the Exynos S22 is lacking bands 260, 261 (5G mmwave bands) and bands 14,29,30,66 so the coverage won't be good

I have the 998b/ds i just purchased . When it came the card in the package said it wouldnt work on cricket. I went to cricket and called. Ran my imei and was told everything would work fine. Cricket if course is att.
I will be calling today and asking why my coverage is so horrible. I wouldnt have opened the phone if they had told me everything would work.
I am experiencing horrible reception at my home, which is in the mountains. My s20 ultra worked fine and got 5 g up here.
I will report back what i find out. As for now i am disappointed i am not getting 5g at all.

Ok thanks. So looks like USA Version is my best bet.
