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

I just got a Sprint phone and I am in the process of unlocking it. Once I unlock it, should I flash the Sprint S7 with the T-mobile S7 firmware since T-mobile is my provider? I know I won't get wifi calling and VOLTE, but I figured the preconfigured settings on T-mobile APN etc will make it easier for me to use the Sprint phone with less issues? The other option was flashing the International unlocked firmware.
What are your guys' thoughts?
No wifi calling option on S10E (SM-G970U1)
Model: SM-G970U1
Andriod 10: one UI: 2.1
G970U1UEU4DTF3
Using MVNO ATT SIM.
No wifi calling option to turn off/on in the dialer app, no VoLTE. MVNO said I am confirmed to enable both options though.
Is this an ATT sim restriction for unlocked/non ATT devices? I did plug in my wife's att sim card and was able to get LTE+ but no wifi-calling. This isn't a branded ATT S10E.

I have an Unlocked S10e (U1) and the only way that I could get those AT&T features was to flash the "U" firmware AND the AT&T User Data file that has all of that crappy bloatware. I also used my old AT&T SIM card that had been in AT&T's system for years on previous phones. I had to do the same thing with my Note10+ too.
Another S10e that I have is still on U1 firmware & I just popped in a T-Mo SIM with no problems. Wifi calling etc. Work except I needed to download a visual voicemail app. Otherwise working great.
AT&T makes it so difficult!
It was a must for me because I have poor AT&T service where I live & need wifi calling.

Thank you, that is what I expected from ATT. I will switch to verizon MVNO. I don't want to have an unlocked phone, only to be forced to install carrier bloat.
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?
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:

Hi,
I use my international variant S7(sm-g930f) on the ATT network, and they notified me that my phone will not work on their network in February 2022 because they are shutting down 3g in my area. They say my phone will not work on hd voice.
Two things I notice is that my phone does have 4g lte, and the ATT variant S7(SM-G930A) will still work.
Is it possible to make my phone still work on their network by installing ATT variant firmware?
Thanks
