Unlocked Verizon to use on AT&T? - Samsung Galaxy S8+ Questions & Answers

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

ATT (phone/Service) unlocked --> Verizon

So,
I have an ATT FUZE phone and service right now and it is SIM Unlocked.
I can also install any ROM (SuperCID?) and I just flashed the rom to ATT's latest Radio/WM6.1 last week.
I'm considering switching to Verizon using the same phone because ATT reception is crap
I'm assuming I can still use the latest ATT Radio (they're all GSM right?) and won't have to reflash the radio to Verizon specific? I should just be able to get a Verizon SIM card and everything else should work straight off the bat no? I know the phone will work with the Verizon Sim.
My concerns are the data -radio wise and speed and reliability with the ATT (specific?) radio.
Thoughts?
Sprint and Verizon are both CDMA.

Well the problem is that AT&T is GSM Verizon is CDMA the phone will NOT work on the Verizon network. The only SIM cards for Verizon is for international calling not domestic and will not work in the states. Sounds like a great plan but it will NOT work. Sorry for the bad news.....
the Fuze is a GSM phone, thus it will not work on Sprint or Verizon. The CDMA version of the phone is the Sprint Touch Pro (will work on Verizon or Sprint). I would see your Fuze on ebay, and us the money to buy the Sprint Touch Pro then switch to Verizon.
DO NO BUY THE VERIZON TOUCH PRO. IT HAS LESS RAM (192mb vs Sprint's 288mb). The Verizon version of the Touch Pro is a waste of money, so make sure to get the Sprint version - you can use it on either network.

T-Mobile Note Edge on AT&T.

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

Will Samsung Galaxy s7 (Rogers, G930W8) work on Verizon?

I have a friend with an unlocked but unrooted Galaxy S7 originally from Rogers (G930W8).
She has T-Mobile, and her phone has always worked fine. She has moved to a spot where T-Mobile service is essentially non-existent, and wants to know if she can use that phone with Verizon, which is apparently the only carrier with decent service where she is.
Does anyone know this?
Thanks.

Should work, as with all US carriers if you're not using a US model phone the band support and network speed won't be as good. But if T-Mobile works then Verizon should too.

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.

ATT on T-mobile

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:
