I am thinking of purchasing a Samsung Note 20. If a phone is unlocked I assume it would work on T-Mobile. My question is if I purchase an ATT variant, I know the phone would work with a T-mobile sim, but will VOLTE (wireless calling) work if it an ATT branded phone and wether there's an issues with updates.
Thank you

Basically it should work.
According to the following thread, there might be some issues using 5g though:

I have been searching for an answer and have not gotten a clear and definitive answer. Does the T-Mobile Note Edge variant work on all AT&T LTE networks without issue after being unlocked? According to tbr Samsung website both models have the same bands with the t-mobile Edge have 2 additional bands
I have the att model but would really like to be part of the dev community. I have a week and a half to return my att model. I would buy the t-mobile model if it works completely on the networks. Anyone out there using a t-mobile Edge on ATT. Thanks

Think I can help answer a few Qs.
Am using a Straight Talk sim (ATT) in my T-Mo Note Edge. Getting 8-15+ mb/s down...2-4 mb/s up (more than enough for me). Followed rooting method posted by TekHD. Did not see unlock procedure for T-Mo Edge.
T-Mo does hold your unlock hostage for 2+ months or $100 (didn't see this stated and argued). Unlocked through a reputable unlocker through fleabay (~$24 I think - Tmo also recommended...go figure).
Hope this helps.
Wish someone can release a qualcomm kernel w OC/UV/governors and thermal control soon...

Yes, Using one right now. You do not need to unlock it at all it will work right out of the box with an AT&T sim as will all T-Mobile Phones.. This has been a thing for years. There might be some obscure T-Mobile phones without perfect LTE Band or Data support. Every major model will work perfect with absolutely no unlock don't waste your money. I actually called T-Mobile before throwing my gophone sim into the Note Edge T-Mobile variant and cautiously asked if they will blacklist the imei of a phone that is using an AT&T sim. The T-Mobile representative kindly, calmly, and with conviction said that no you will not have your device blacklisted, and that all T-Mobile phones should work out of the box on AT&T. Enjoy not paying for an unlock code! I'll upload pictures of my note edge running AT&T data services via an AT&T gophone sim if you don't believe me. It actually put the APN information in for me automatically too! Meaning I did not have to enter in carrier specific AT&T APN, the software on the Note Edge T-Mo variant picked up the different carrier and entered the APN settings automatically. Woot woot

strange. I have my att sim in a SM-N915T on 6.0.1 N915TUVS2DPG2 and it says network locked.
Anyone know if it's possible? Found a deal on CL for an unlocked Verizon S8+ that is all clear to activate. Put a T-mobile sim in it and works fine but seller doesn't have an AT&T chip to test.
It's fine but u won't have volte unless u have att version
It works but you get mostly hspa no LTE due to band limitations
Hello everyone,
I bought a samsung s10e that I suspect is the AT&T version G970UZKAATT. This phone is supposed to come sim unlocked.
- Does that mean that when I insert a TMob sim card, will it reboot like the S9 and the TMobile logo will show up, then
the phone will work just like a regular TMob version G970UZKATMB?
- Will it have wifi-calling for TMob?
- Will it support all TMob LTE and HSPA frequencies e.g. band 71?
- Do all versions of the G970U support the same frequencies once unlocked just as these websites suggest?

Hardwares all the same. No, it wont boot with a Tmob logo. If you want it to act like a Tmob G970 flash the Tmob firmware.
I was just testing a S10e that has G970U1 as model (probably flashed) on the back says G970U.... I inserted an Ultra Mobile SIM card (TMob mvno) and it seems that the wifi calling works on the unlocked ROM .... So no need to flash TMob version, I believe.
Can anyone confirm wifi calling works on the factory unlocked version?
I have the g970u1 factory unlocked with u1 firmware. It has tmobile wifi calling. The only things missing are tmobile video calling and that rcs messaging I think. But, I flashed the tmobile u firmware a couple months back and the phone booted up like a tmobile branded one with the jingle and stuff. I didn't need those so I reflashed the u1

Thank you so much for confirming. I've just got my g970u1 factory unlocked and wifi calling with Ultra (TMob mvno) seems to work too. I tested using airplane mode enabling just wifi and I can still make calls
Will an unlocked TMobile version of this phone work on an existing Verizon line without having to ask verizon to white list the imei or add cdma less etc?

I have Unlocked T-mobile A71 5G, It works on Verizon network like 4G LTE (just swap the SIM card even I have 5G Sim card from Verizon) but NO 5G because they are using different 5G Band.
I have the same question, but on cricket wireless, I can't get the phone to login to their network
It works just fine on any GSM/LTE network. I have not checked this personally for this device, but depending on the variant you have, you may be missing some LTE or 5G bands specific Verizon. You may not get full performance. That must be verified though.
I am using a sim unlocked T-Mobile A71 5g with a cricket sim. VoLTE does not work. If I flash the AT&T firmware onto this will it allow VoLTE to work? Will it relock the sim unlock? (I highly doubt that is the case, but want to cover my tail.) Will it allow me to use LTE band 66?
Thanks
HOw is Cricket not blocking your acccount? I bought one for my mom and its unlocked for ATT network and it works for like 5 mins and then says its not compatible. I masked imei with ed exposed and still cant get it too.

Hey if it's rooted you can use short cut master lite and open Cid manager and it will change your csc and network you can pick AIO which is Cricket .
I am not rooted. I heard that that google pay and Netflix quit working if you root a phone. Haven't tried rooting a phone in the last 3 or 4 years. Kinda out of the game.
I am having a similar issue. My phone is an unlocked T-mobile and on AT&T TOGO. I keep getting my outgoing calls redirected to AT&T cust srvc. They say my phone is not VoLTE capable and therefore will not work after 3G sunset. T-mobile support site says VoLTE is enabled by default, just that there are no settings to turn it on or off. Wondering whether it's safe to flash with AT&T ROM? Or maybe generic Samsung ROM if available?
Please I'm in Nigeria, i bought this A71 5G front a vendor at second hand. But my local sim card won't work on the phone.
How do i unlock sim?
