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

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

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
So I had a boost phone that recently broke. It had a sprint sim card. My mom got a new phone and gave me her S6 SM-g920a. I had to go online to get it unlocked. Upon unlocking it and it not working I called att. They told me it wasn't compatible. Ok.. So then I read on xda if you root it there's a way you can unlock it for my sim. Cool. Problem is my computer fried the other week. No oden no flashing nothing. My questions - Is it true rooting it will really make the sim compatible? And can you root this phone using no oden or even computer?
Thanks in advance
Not really.
The S6 SM-G920A is an AT&T phone (the A at the end of the model indicates AT&T model) so it uses GSM technology and can work with only a GSM SIM card.
Boost and Sprint are both CDMA networks, this means they use CDMA technology.
So, your phone, previously from AT&T, recognizes only GSM bands. Whereas Boost and Sprint use other bandwidths.
Check your phones and networks bads here and see if they really are compatible: https://www.frequencycheck.com/carriers/at-t-united-states
If their not, then you could use this phone only with GSM networks, such as AT&T, T-Mobile, Cricket, MetroPCS
Well that's just disappointing. Thank you very much for your help though
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 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:
