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?

Can anyone tell me if the phones is region locked? Thanks
i am not sure what you are looking for but i do know that there is a thread on here where someone tried a Verizon SIM in a Tmob and ATT S6 and neither one worked on Verizon.
Generally Verizon phones are SIM unlocked so u can use them on Tom or att but don't expect to get lte coverage since the phones have different bands enabled.

That's because those don't have CDMA radios, and at least the AT&T one is locked. Verizon phones come SIM-unlocked and work with other carriers. If you use a T-Mobile SIM you'll see an "unknown SIM" message, but it will work assuming the bands match. You should be able to get LTE with T-Mobile as most of their network uses band 4.
He means region locked, like usa

Anyway to get rid of this message? My g2 I had to root it to get rid of it. I hope I don't have to root the s6 just for that because it gets really anoying just having the icon showing unknown sim the whole time.

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

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 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:

ok so i have this new s22 ultra SM-S908U and it was connected with Verizon wireless originally. cricket when doing an IMEI check said it was not compatible, I called and Customer service confirmed it was not compatible due to network band differences. i decided to try using the cricket sim anyways and it worked for about a hour then cricket locked the sim and i had to get another sim,
Does anyone know if and how to get this to work on cricket if possible? I did try this band unlock
( https://forum.xda-developers.com/t/...ies-including-sub-6-and-mmwave.4488435/page-5 )
also but not sure if i did it right it locked the new sim and again i had to get another one.,
Also I did check with verizon and the phone is sim unlocked
