Model purchase advice - Samsung Galaxy Note 9 Questions & Answers

Looking for a Note 9 for my wife and there are two attractive offers out there today. T-Mobile has the 128gb for $870 and Amazon is selling the 128gb, factory unlocked, along with the wireless charger and Bluetooth earbuds, for $929. We don't really need the earbuds, but the charger would be useful, so these are fairly equivalent offers to us.
We're currently on T-Mobile, but if the band 71 rollout here in December doesn't fix our signal reception inside buildings, we're likely heading to AT&T.
So, I may need to switch the phone to a new carrier early next year. That would seem to indicate that the carrier unlocked version is the safe bet, but I know Samsung has a bad rep when it comes to updates to firmware for the unlocked phones.
If I go with the T-Mobile version, can it later be flashed with AT&T firmware to get all the bells and whistles (VoLTE, visual voicemail etc)? Are there any other important issues I might be overlooking with regards to carrier vs unlocked?

They are the same device hardware wise. The unlocked U1 models tend to maintain their value better for some reason, so that's something to take into consideration. Right now, you CAN flash a different carrier's firmware on the carrier or unlocked version. If you buy the T-Mo version, you may have to flash the U1 firmware, and then flash the ATT firmware.
Since I haven't received my Note 9, yet, and I don't have ATT, I can't confirm this, but with the Note 8, people who flashed ATT firmware on non-ATT Note 8s had issues getting WiFi calling to work and they didn't receive OTA updates. You might keep that in mind and do some research.
If it were me, I'd snag that $929 bundle in a heartbeat.

That's all good to hear. It's a shame AT&T makes things so difficult, but hopefully tmo's band 71 rollout fixes our reception issues and we never need to go there.

I did just that an hour or so ago.

So take this with a grain of salt: You're able to use an AT&T branded device (I did it with an S9+, now with a Note 9), and flash that with the unlocked or t-mobile firmware, and everything will work beautifully.
HOWEVER, I hear AT&T uses an IMEI whitelist for their VoLTE, which is ridiculously dumb, but MAY keep you from using VoLTE even after you flash AT&T firmware to a non-AT&T device.

Xfinity Mobile version? ($300 off via prepaid card rebate)

I'm surprised I haven't seen much talk about this version here, or Xfinity Mobile in general. It is definitely the best option in price (to purchase a single Note 9 with little service commitment) over the unlocked version without being being too much of a hassle to get the rebate.
For myself, that means I activated a prepaid line (T-mobile, $10 sim, $6 for 2 months of service) to port to Xfinity in order to get the rebate. I'm on Sprint's 1 year free plan until the middle of next year, and since I already subscribe to Xfinity Internet at home, I might as well use that as an advantage to get the discounted phone. Since my main # is on Google Voice, I use their call forwarding to the carrier number currently, so I can do the same on Xfinity -- forwarding calls for the first month (or 2) until I can request an unlock code. For the first few months, I will actually use the service in part and keep it active to get the rebate (and get paid for it!), since I also have a BankAmeriDeals $50 cashback offer from Xfinity Mobile once 2 monthly billing charges hit. The timing was very sweet on that one, ha!
For others, I understand this offer might be too much work, as would be the alternate solution of switching carriers altogether to Xfinity Mobile, which is more than likely why it doesn't have that much appeal. That being said, I wanted to point out that this option is available, and start this thread for discussion on supported bands related to the Xfinity, or Comcast (CCT) model.
Known/deduced information so far:
128 GB model #s: SM-N960UZBACCT (Ocean Blue), SM-N960UZPACCT (Lavender Purple)
512 GB model #s: SM-N960UZBFCCT (Ocean Blue), SM-N960UZPFCCT (Lavender Purple)
I cannot find any information on the supported bands for this CCT variant other than (what I hope is) a limited list from the Xfinity website (B2, B5, B13, B4, B66).
Is the below assumption incorrect? I've been on Google devices for a while and I've been out of the loop with Samsung:
1) Once released, factory unlocked US firmware (XAA) can be flashed to this CCT (or any other) US carrier variant, and this should enable the bands supported by the US unlocked firmware.
Finally, if anyone has a previous Galaxy S9 or similar on Xfinity, can they comment if the bands on the device are the same or similar to the Verizon (VZW) variant?

I disagree that it's definitely the best option for a discount in price. Verizon BOGO and T-mobile $500 off are better, in my opinion. Yes, they're bill credits, but I'm not going anywhere anyway. More money off = better to me. I think T-mobile is the best one since it's basically just half off the phone.
I have Comcast and had Verizon. I thought about the Xfinity thing but then it's the same old game is taxes and fees increasing your bill. I'd pay about $36/mo for 3GB (still restrictive) and then with taxes and crap I'd be at $45/mo for limited data and I'd be watching my usage still (as I did with my 3GB on Verizon). Instead, I opted for T-mobile and will be paying $33/mo (as part of a 6-line account) for unlimited data and no taxes and fees. That makes me a happy camper. Plus with T-mobile Tuesdays, I'll get free Pandora Plus for year, I get free Netflix for life, free MLB TV each season, etc. I'm loving this company so far! And for $10 more, I can get 20GB of 4G Hotspot a month. ?
Anyway, I really did consider Xfinity wireless. The biggest turnoff was the lack of phone options, promotions, and the data is costly.

This is why I clarified for a single phone purchase. I think I needed to be more specific and mention without a long term service commitment. With any other carrier I would have needed to:
(1) Do a credit pull
(2) Stay with the carrier for 2 years to deal with bill credits (no thanks)
(3) Pay more than I do now for service (current bill w/ Sprint's free 1-year plan is <$20/mth for 4 lines) -- I'm not staying w/ Xfinity after I get the rebate, heh. Once the Sprint taxes+fees gravy train is over I'll see where I move
If anyone has any insight for the supported bands on CCT (Comcast/Xfinity models) I'd appreciate it.
Would US XAA firmware be able to be cross-flashed to this CCT (or any other) US carrier variant to enable the bands supported by the XAA US unlocked firmware? From the searches I did yesterday, it seems like it is possible, but may require a modified Odin version?

Since the S8, all of the S and Note line devices that are US based have the exact same hardware and features. It's the exact same phone with different carrier software. What funny is, if your unlock the device and just pop in another major carrier sim, Xfinity apps and bloat will be gone and the carrier sim you put in will populate.

That's good to hear. So assuming anything else is unchanged in the Samsung ecosystem, the US XAA firmware can be loaded onto any US carrier variant, yes? My understanding is that the different carrier firmwares enable/disable specific bands.
If root was available, it would seem that bands could be added regardless of the carrier firmware [1], however, root seems unlikely for a new flagship device unless the engineering firmware happens to leak.

Correct, the bands that are open is dependant on the SIM Card inserted. The firmware on the device has every single supported US carrier required files with the exception of a small few. Carriers such as Total Wireless or the Walmart ones won't have firmware specific files, but because those carriers don't have their own towers, the device will use the files for the carriers that own the towers.
Example of Xfinity mobile. They just use Verizon towers for their service coverage. Xfinity however piggie backed their files or Verizon's in the firmware. Rooting could allow more bands to open.
Man I would love to see some hardware hacking of the S and Note series to allow them to work fully on Google's Project Fi.
I have the Xfinity Note 9, and having come from Verizon I immediately save the $20 line access fee, so it's a win if you want to be on the Verizon network.
So far my only complaint is that voicemail isn't transcribed. Should be, but doesn't seem to work.
For those wondering, Mobile Hotspot (using your device as a hotspot) works just fine with either plan. It's just hard to Google search for an answer because Xfinity has mobile hotspots that augment their signal.
I made the switch and save money too. Got the $300 rebate card, save $20/month so it is less when you factor it all in. That's $540. [emoji3]

Which unlocked Note 8 with a Tracfone sim for best experience?

Based on my past experience, when I used an AT&T unlocked Note 4 and S5 with a Tracfone sim(T-Mobile as the underlying carrier), I would have sporadic calling issues with no audio during phone calls. When I made or received calls, the other person could not hear me or I couldn't hear them. In some instances, we couldn't hear each other. Data was always working good and displaying 4G LTE and SMS always worked. I even had the band set to LTE/GSM after trying Automatic. (https://support.t-mobile.com/thread/140917)
I switched the Tracfone T-Mobile sims with Tracfone AT&T sims and all of these call issues disappeared. Of course, I had to set the band back to Automatic. And set the APN to get 4G LTE. When considering this issue, it leads me to this question:
Since I have the opportunity to purchase any brand of unlocked Note 8 and use it with either of my Tracfone sims (AT&T or T-Mobile), which Note 8 model do you recommend for the best experience considering phone-to-carrier compatibility and less importantly, bloatware/Android speed?
My first choice is the SM-N950F which doesn't have any bloatware, but I'm not sure how seamless it would work in terms of network/band/data compatibility issues. I'm researching this now. Any input on this would be greatly appreciated. Thanks, Graz
Basically I learned when using the international SM-N950F with any U.S. carrier including Tracfone, you will not get certain features these carriers offer: Visual VM, WIFI Calling, Video Calling. So why even bother buying a branded AT&T or T-Mob Note 8 because all of the bloatware included on these phones won't be able to be used anyway for these features, nor will I get OTA security updates with a Tracfone sim.
So, I'm thinking the SM-N950F or even the U.S. unlocked unbranded Note 8 may work better because they don't have the bloatware I can't use anyway. But which if any, would work better in terms of calling, banding, or data compatibilities with a Tracfone sim(AT&T or T-Mob underlying carrier)?
Thanks, Graz
---------------------------------
EDIT: So far (and I may be wrong) I learned:
It seems the International (SM-N950F) version and U.S. Unlocked version (SM-N950U1) can both be rooted but it seems there's more info on rooting the SM-N950F by Max Lee.
The International (SM-N950F) sometimes may not come with a manufacturer's warranty depending on were you buy it from.
Both Note 8s will work with U.S. carriers, but according this page, the U.S. Unlocked version (SM-N950U1) has more bands/frequencies. https://www.techwalls.com/samsung-galaxy-note-8-sm-n950-model-number-differences/
---------------------------------
EDIT AGAIN: What I decided to to was purchase the ATT branded SM-N950U and flash one of the following UNLOCKED firmwares to it to remove bloat:
XAA This firmware will provide for a bare bones, no bloat experience
ATT or TFN: These will have some carrier files, but very little bloat. Not sure if these unlocked firmwares will provide features like WIFI Calling/ VOLTE.

note 9 verizon vs note 9 tmobile

I have an up to date verizon note 9 although still paying for it I had it on their service for over 6 months so legally allowed to use on another service currently using it on cricket with no issues other than no VOlte which I've never had with cricket no matter what phone because I won't use the phones they have because I don't like them but that's another story....Since I can't get volte on my Verizon model note 9 that's fully updated for US I was wanting to switch to tmobile...I was set up with a sim card on their magenta plus plan worked great till I got to my home which is in a more rural area but did show verified coverage at driveway on their map I had no signal so I went to settings searched for mobile networks found tmobile listed registered and it connected like 2 bars LTE but within min lost service did it again lost service again while I had lte I was able to call and use data...so my question is could this be me using a verizon phone for it not latching on by itself or holding the signal I know note 9 has the 600mhz band but was wandering if I went ahead and got a tmobile phone if it would actually latch on and hold the signal that Verizon's addons and changing is playing well with tmobile...UNLESS someone can tell me how to get VOlte on cricket with this note 9 then I wouldn't need tmobile then 3g calling has went to crap over a year....thankyou for any input

All N960U and N960U1 devices are EXACTLY the same. The only difference between the devices is software.
Flash the software for the carrier your running including the Userdata for you Note 9. It should work for all features especially on T-Mobile. T-Movile fully allows unlocked devices on their network whereas Verizon doesn't. I'm pretty sure at&t is like Verizon through when it comes to unlocked devices, and they own cricket so that rule probably trickles down to them as well.
You can get all carrier version of software for your Note 9 on samfirm or sammobile

But my question would be would my phone latch on to tmobile towers using tmobile firmware better than my current state using verizon firmware I'm excluding wifi calling and volte just trying to determine if I would have a difference in service availability picking up towers and holding them with stronger lte signal or if it's just poor coverage both ways and will be no different than you for your advice as well

You will not have a difference in coverage. T-Mobile did the same thing with where I live and listed it on their map as being fully covered. I barely get LTE at my house or anywhere in my neighborhood.

Okay thank you for saving me the trouble of doing firmware swap or just buying a phone from them just to try and have same result and have to return....man I wish cricket would sell the note 10 or 9 where I could get the volte...but thankyou for your time

You will never know until you try it, so why not try it and find out? Make it an SM-N960U1. Debloated and ready to go with any sim you install. Flash the unbranded firmware that can work on any of the US providers. That's what I have, and when I loaded a T-Mobile sim, I got VoLTE and wifi calling. I've run a lot of custom firmwares in the past, but this is the best phone and firmware combo I've ever had. And it's pure stock.
Also, this stock One UI with dark mode is very slick. VERY! No Substratum, no themes, no fuss. Just clean and black.

His goal is better service reception.
Only the carrier can fix that by actually providing the coverage they put on their maps.

Lots of people have reported better or worse quality service, all other things equal except for firmware/software: different radios enabled/disabled; different optimizations. I just read another thread where someone got better tmobile reception at his house after flashing tmobile software over US unlocked software. There are more variables than just the carrier side of things.

Thankyou then that kinda answers my question that although phones are equal between verizon version and unlocked internally and firmware being the difference that using a tmobile phone with their firmware I'd stand the best chance of service and since my area uses extended range area I would probably have a better experience than on my note 9 verizon...thankyou again

Yes. I think it may make no difference at all, or it might (much to gain, but nothing to lose), but most of the evidence in these forums, when it comes to connection quality, is extremely variable and anecdotal. Nobody can know an answer to this kind of question, unless they test it out for themselves. Good luck!

Carrier Unlocked vs. Factory Unlocked vs. Carrier & eBay adamant GSM & CDMA different

Carrier Unlocked vs. Factory Unlocked vs. Carrier & eBay adamant GSM & CDMA different
Carriers and vendors on eBay have been adamant that a SM-N960U phone is different, and you cannot use Note 9 phones that came from GSM wireless providers on a CDMA networks and vice-versa. They become incensed and assume a position of superiority at the very suggestion that the differences between network today are often handled by changing firmware. With all of the US Note 9s being the same hardware, this is my take on where they are coming from.
1. If it says carrier unlocked for example: AT&T, it will only be compatible with GSM networks (GSM networks---AT&T, T-Mobile, Cricket, MetroPCS by T-Mobile) - My interpretation is that's only true if you don't flash SPR, VZW, or XAA/U1 firmware, and even then that is not necessarily true in the 4G range.
2. If it says factory unlocked, it will work with all networks-- both CDMA and GSM - My interpretation of that is, it seems their idea of "Factory Unlocked", actually means the phone is running the XAA/U1 firmware.
3. Their refusal to even entertain the possibility of a single model with different firmware working across all of the US networks stems from a long history of cell phone models only being able work with a single wireless provider's bands and proprietary technology.
Correct me if I'm wrong in my logic.

i wouldint be surprised that alot of the postings on ebay have the same device under different carriers or just simply generically stated as unlocked. they want more than just 1 result popping up to make it as visible as possible. whether this is legal or not is something to debate with ebay. but i wouldint be surprised savvy vendors would be doing this and depending on which posting was bought, would simply flash carrier firmware or u1 firmware. there are also the ones posting 2nd hand handsets that might have initially been on one build and and along the way was flashed and sold under its original device banner because they looked up product code/serial and sold it as that. also not to mention phones still on contract which can be a time bomb.
Ebay's a jungle. but if you know your rights and have the right arguments to prove your case, you can return almost anything. and if that doesn't work, 2nd stage is a case with paypal.

I've also been noticing the fine print on the listings that quite a few "good deals" state in the fine print that it is on a contract.
I'm just sticking with there is no difference in the hardware and they are all the same hardware all capable of the GSM and CMDA bands with the proper firmware, no matter what they say about not being able to work with Verizon, and that I can take it to Verizon or T-Mobile. The only thing I might believe is one of them who said it work work with everyone but Sprint, whose issue is most likely based on an IMEI restriction than any capability of the phone.

Just bought a refurb Note 9 from Amazon...
I realize this is an old thread.... but it is just what I've been wondering.
I bought a Samsung Note 9 phone, labeled (somewhat conflictingly) as completely unlocked but (later on) as only a GSM phone. The model number on the phone is N960U1. That's on a printed label on back of the phone and in the software settings (UI 2.0, as 2.1 hasn't come out yet with this model and T-Mobile[??]). However, I note that lifting the sticky label, the original on chassis number beneath it is N960U (a carrier specific phone).
I thought I knew about phones - I've flashed two other (make that 3 other including my wife's) older Samsung Note phones w/ custom roms because I was tired of being back with Marshmallow.
But fundamental questions I have:
1. Is the N960U phone the exact same phone hardware wise as the N960U1?
2. In other words, is the software lock the *only* difference between these phones?
3. And does that mean I could presumably, once my phone (unlocked by whatever provider once had it locked) is identified as an N960U1, run it on GSM, CDMA, and have access to any and all services offered by whatever provider I choose?
And finally, which is where I began all this, will this phone update to the UI 2.1 eventually as an unlocked phone with that specific (still not available) N960U1 update? Or is the phone in some state of being "neither fish nor foul" - that is, not *really* a fully unlocked phone?
I am asking all this because I could still send it back to Amazon if it is less than it ought to be and get something else.
It is currently running the June UI 2.0 update from T-Mobile....
Thanks for any thoughts. The deeper one digs, the more questions come up.

1. Yes
2. The U vs. U1 is not indicative of a lock vs. no lock. U phones can be unlocked or locked. The U firmware is wireless-provider-specific firmware. It could be Verizon, T-Mobile, AT&T, etc. Each have their own firmware to work with their specific networks. They will also force updates on you whether you want them or not. The U1 firmware is standards-compliant support. The better the wireless provider supports the standards, the better U1 works. T-Mobile supports it perfectly but has some loss of functionality with allied vendors. You may never notice. Next, is Verizon. Verizon was CDMA, so its 3rd gen stuff won't work like the GSM networks will because they don't have any anymore. However, all of the 4G will, and Verizon has more 4G coverage than any of the others have 2+3+4G coverage. Thus, you don't miss the 3G like you would AT&T who is 25%-30% less than 4G, but AT&T has always been GSM so coverage-wise it is close to Verizon. For standards compliance for U1, AT&T is dead last by far, and if that isn't enough, the most resistant to accept a phone not sold by them. If you do not buy a new phone through a wireless provider, it will be a U1 phone. With a U1 phone you can prevent it from updating if you hold your mouth right. You cannot stop a U phone from updating. Other countries were behind the US so they tend to be more standards-compliant because they weren't as heavily in the game when the innovation was taking place. That means for traveling and swapping SIMs for different foreign carriers, you would want the U1. The Note 9 is the first Note with about every band known to man like the iPhone.
3. Yes
4. If the phone was purchased as a U1, it is undoubtedly unlocked because the seller is not selling it on a contract, and has no idea which network the phone will be used on.
Everything I've read, the 960U /U1 are the same hardware. To support that, their firmware modules are the same except one that is carrier-specific. The U1 for the Note 9 is not carrier specific. I had a T-Mobile Note 9 that I used on the Verizon network with no issues. I have a Verizon Note 9 now, and there is no difference. The only reason I have the Verizon Note 9 now is because the brand new T-Mobile one, still sealed in the box and with the protective film on it, ended up on the bad MEID list. Apparently someone bought it and brought it back without using it and stopped paying on it and thought they were out of the contract by doing so. The Verizon U phone that I have now has been flashed to U1 and works fine on their network. So the advantage of the U is its supports all of your carrier's services. The U1 supports all of your carrier's services that are standards-based and don't use carrier-specific services. Example, if the carrier supports support VoLTE, U1 will not usually support it because it must coordinate with the carrier's servers while U will. They say the U1 doesn't have the carrier bloatware. I don't agree. The carrier-specific added services are designed to work with their servers. Moreover, in the areas that need to be filled in, you get the basic programs from Samsung to replace the more capable ones you get from the carrier. I use U1 because I need to stop them from updating me due to my line-of-business software on my phone and for International travel when I replace the SIM with a local network SIM. If that's not you, and you want the latest for your carrier, U is what you want.

Thank you for this. Very helpful. I'm not sure yet whether I'll send the phone back.
UPDATE: Samsung released the T-Mobile update to UI 2.1 (dated July 7) today, August 11 2020.
NOTE: I installed this and hit an issue after the install completed re an error message (see photo). This error apparently is happening in a widespread way, and the 3 solutions offered by Samsung did not work. What *did* (I think) work for me was to go to Settings > Software Update > UICC Unlock. Beneath that button on the N960UI it reads (as it should) "Your device is unlocked to support any sim." I click it anyway and I get a report that my device sim is restricted, bla bla bla. I hit the "OK" and reboot the phone to see... and sure enough, that's all it apparently took to remove the annoying nag about the install not having completed. In fact I get a successful "handshake" message between T-Mobile and the phone having formed a more perfect union or some such.

You can flash between any carrier U and U1 firmware at any time. The only thing you need to be aware of is the boot loader version, which is the 5th character from the right in the build number.
- It must be the same number or higher.
- You cannot flash backwards to a lower number.
E.G. You can flash from a newer version of Android to an older version PROVIDED the older version does not have a lower boot loader version. If flashing the newer version of Android changed the boot loader version to a higher version than the older operating system supports, you cannot flash to the older version of Android ever again. The boot loader version is not synched with the the Android version. It is synched with the particular build. Thus, you might get an update to the current operating system that increments your boot loader. If you like to always be on the latest version of firmware, this is no likely to be a problem.
For the SM-N960U/U1 phones, the various carrier versions, U, and the U1 version are released at the same time. A lot of standardization has occurred and made possible by the hardware being the same. In the U1 versions for the SM-N960 you will see carrier names associated with different downloads. It's all bogus. The downloads are all exactly the same with the same module names, size, and the same MD5 signature.

VERY helpful info here.... as of this morning Samsung updated my phone w/ UI 2.1 T-Mobile files. I posted on it elsewhere as a recurring error popped up. Surfing the web shows that error cropped up for all sorts of people doing the 2.1 update on various carriers. I *think* I found the solution but have posted it enough places (including a few posts back in this thread) I won't do again unless someone here wants it. Samsung's "solutions" (all three of them) do not work. Oh, I think I'll hold on to this phone rather than switch out for a T-Mobile specific... gives me more lattitude down the road when I feel like rooting it. Ha!

As far as the difference between the one you have and T-Mobile, there isn't any difference. If you want T-Mobile specific, simply flash their firmware. The upside nearly all of T-Mobile's network was late to the game so their network had little non-standards-based legacy to deal with and thus works very will with the U1 firmware as well. You can always switch back and forth. Different carriers have different MEID ranges. A few carriers, such as AT&T might deny you based on that number not being theirs, but it is not a phone capability issue since the hardware is the same.
You cannot root any of the U phones at this time that I'm aware of. There has been talk and they've been able to do it soft of but not without serious snags in functionality. All N960s sold in the US are U/U1 phones with the SnapDragon processor. There is a SnapDragon that is rootable and dual-SIM, the SM-N9600. In China you may not sell a phone that is not rootable. However, that phone is also used in many other countries. It should work with T-Mobile too, BUT there may be some performance limitations because it might not support all of their bands. Verizon won't accept it initially, BUT a lot of people have activated the SIM on an approved phone, and then moved the SIM the SM-N9600 and it works fine. The SM-N9600 supports all of Verizon's LTE bands. The downside is you cannot use Samsung Pay, the best pay system out there. The SM-N9600 is in demand which affects the price. It is a good world phone with SnapDragon/Qualcomm and a well implemented Dual SIM. You may see it said that the SM-N9600 doesn't work on a CDMA network. That may be, but Verizon has hardly any CDMA left themselves because the FCC is kicking them off it. They won't have any by year end and were supposed to be and almost were by year-end last year. There is more to the game than GSM vs. CDMA. It is also support for the major specific band for the carrier that is used to log you into their network, which is independent of which band you will communicate on. That is a potential show stopper. About the only place in the world where the SM-N9600 has any issues is in the US. If you can get your carrier to work with it, you are pretty much golden for the rest of the world.

How did you successfully flash U1 software on your Note 9? I tried doing this back in March unsuccessfully as Odin threw up an error.

Unlocked V405TA (T-Mobile) vs Unlocked V405UA (AT&T) for Google Fi

Hi everyone,
I'm planning on purchasing a preowned V40 mainly to be used as a portable music player but also as a backup phone. I'm on Google Fi and was wondering if it would be a better idea to get the V405UA (AT&T) model over the V405TA (T-Mobile) model. Both are around the same price and both are unlocked, so there shouldn't be any problem using them on Google Fi.
However, I read that the T-Mobile version of LG V-series phones (e.g., V30, V40) are a pain to work with due to proprietary RSA encryption, so I was thinking that the AT&T model might be a safer bet in case I wanted to root my V40 in the future. Currently I understand there's no bootloader unlock or root available for the V405TA (T-Mobile) model. Personally I don't really care too much about root, but it'd be nice to have the option.
But I also read that AT&T phones need an AT&T SIM card with an active plan in order to receive OTA updates, so I'm thinking it'll be a huge pain to install any future security updates if I get the AT&T model.
I'm aware that the V405TA (T-Mobile) model will support more of the bands that Google Fi uses since Google Fi mainly uses T-Mobile's network, but the AT&T model should still work with Fi, albeit with worse coverage.
Thanks, and let me know your thoughts!

I'd say you'd be much better off going with the AT&t model. The only band that wouldn't support would be 71. With the AT&t, you could flash it to the US open version and it supports band 71. Well yes, you would get updates with the right carrier sim, they seem to be few and far between.

Makes sense, thanks! I'll plan on getting the AT&T version.
I would like to have Android 10, though, and if I'm not mistaken the V405QA (US Open version) only has Android 9, and given the sparseness of software updates LG has released for the V405QA it seems unlikely that they'll release an Android 10 .kdz for the US Open model.
If I plan to use stock AT&T Android 10 firmware, that means I can't use VoLTE or VoWiFi on T-Mobile, correct? I'm aware that I can also crossflash to the Korean V409N firmware for Android 10, but I'm not sure if that would solve the VoLTE problem.
I'm concerned because I read a post by ChazzMatt in the V30 forums stating that T-Mobile will be dropping 3G HSPA support in January 2021, so I'll need VoLTE or VoWiFi to continue making carrier phone calls. In that post, he said that that T-Mobile allows V30 phones on US Open firmware to use VoLTE and VoWiFi, but I'm not sure if this would also apply to a V40 phone running Korean V409N Android 10 firmware.
Any thoughts would be much appreciated!

You've done some research, good. Let me point out a few things;
1) The US Open version should be updated to 10, pretty soon hopefully.
2) Between EBW Open and Korean Open, def go with the Korean, it has support for bands 66 and 71 (in addition to the others), but the EBW does not.
3) Near as I can tell Lineage doesn't have volte or vowifi.
4) With some tweaks to config files, Korean Open 30d does have volte, but not vowifi (this may be possible but I haven't gotten it to work yet).
5) Yes, AT&T firmware won't allow volte or vowifi unless you are using one of their sims.
6) The v40 with US Open Pie does support volte and vowifi on T-Mo. Caveat, I'm using Mint mvno (which uses t-mo towers).
At this time, myself, I'm just having a little fun while waiting for the NAO US Open 10 to drop. The rom that seems to have the most of what I want now (with slight mods), is the Korean Open 10. It also appears as though it's doing 'carrier aggregation', because the signal is exceptional (although some have said the actual signal strength (dBm) may not be any better).
So, if u have to have 10, right now, backup your at&t device (use qfil or edl.py), and crossflash to korean open. Then follow this thread for additional tweaks.
cheers

Awesome, thanks for the extremely helpful reply!
One last thing: if I want to have the option to switch from Fi to an AT&T MVNO in the future, I should probably get the last Android 10 AT&T OTA update for my V40 and back up that firmware for VoLTE and VoWiFi before cross-flashing, right? I read somewhere that once you cross-flash your device, even if you return to the original firmware that came with your phone, you won't be able to receive OTA updates (and AT&T doesn't release any KDZs).

Well there's already a qfil backup of at&t 10 in the 'partition backup request' thread (or some name like that). But will there be any more updates from at&t? I think that's highly unlikely. There *may* be some security patches, but that would be it.
I guess if you use an at&t mvno, you may need at&t firmware to get volte and vowifi, don't know as I don't use those mvno. But on t-mo mvno (mint mobile), I have volte and vowifi with us open firmware (had to go to my mint account and select 'allow vowifi' for it to work).
Sounds like you'd want to check on at&t mvno's, to see what their requirements are to get volte and vowifi.

Any guess how soon? I must have Android 10 on my unlocked LM-V405QA by mid December. Called AT&T and they could not push it (probably because THEIR variant of V40 ThinQ is different).
