Carrier compatibility on unlocked AT&T S8+ - Samsung Galaxy S8+ Questions & Answers

I have an S8+and I got the unlock code from AT&T. I wanted to give it to my brother in law. He is on US Cellular. His current phone is a flip phone so he would have to get a son card from us cellular. But if it isn't compatible with the US cellular network then there is no point in getting to give it to him.

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

strange. I have my att sim in a SM-N915T on 6.0.1 N915TUVS2DPG2 and it says network locked.

Any way to carrier unlock this phone?

Is it possible to carrier unlock this phone? Are the radios compatible? I really want to use this on AT&T or T-Mobile.... thanks for any ideas or help.
Radios are compatible with AT&T & T-Mobile (not all LTE bands, of course) but there isn't a way to unlock for domestic usage ATM (except by Sprint). Sprint is supposed to unlock it for you after you've fulfilled your contract. Perhaps contact Sprint Customer Service and see if there are any circumstances for early domestic unlocking.

Can anyone make sense of this conversation I had with u.s. cellular?

Hello. Does the LG K8 prepaid phone come unlocked? domestically or internationally or both or none? Thanks.
The that device is unlocked but it isn't a world phone and it can only be used in the United States. ^Andria
Hi thanks for that reply. But in saying that if it is unlocked and it is used overseas on a 2g or 3g or 4g band that the phone supports it should work?
It's unlocked for use with another U.S. service provider but it can't be used abroad because it doesn't have world phone capability. ^Andria
What I can't figure out is does she mean its domestically unlocked but internationally locked? ( that wouldn't make sense would it?)
Or is she clueless or trying to bs me in how I said about the frequencies?
Lol.

G930W8 with Verizon or T-Mobile?

I am thinking of getting an unlocked S7. It seems to me G930W8 has the necessary LTE bands for Verizon and T-mobile, which are the carriers used in our family. Does anyone have any experience with either US carrier? Is there any issue? I am picking this model mainly because it's not bootloader locked like the Snapdragon models (US models), so in the future I can load any custom ROM.

Did you ever get this phone and find out if it works on Verizon? I have rooted my G935W8, but my friend's G930W8 is unlocked and unrooted. I am trying to find out if she can use it on Verizon. The Verizon reps where she is says it will not work. She has just moved there, and needs a working phone. She was using it on T-Mobile, but that doesn't give her any service in the part of Utah she is now in. If she were somewhere she knew people, I would have her ask someone if she could test their sim in her phone, but she doesn't know anyone there yet.

Question Tmobile user, preordered sammy unlocked version - question

Hi folks. So I am on t-mobile but preordered the Samsung 256gb unlocked version. This is my 1st time ordering from Samsung directly as well 1st time ordering an unlocked device. Usually I just go into the t-mobile store or their website for any new phone purchases. Samsung offered some great trade in values on our S10's and some other goodies so we went directly with Samsung.
Dumb question but will I run into any issues with tmobile and this unlocked flip 3 or is it a simple insert my tmobile sim and off I go?
Phone tentatively arrives 9/21. Thanks!
Simply insert your sim and go!
I always buy unlocked phones, and the last three in the house are on T-Mobile, juts swap sims and you good to go.
The only thing you'll miss out on from T-Mobile is if you roam in a US Cellular area. Only T-Mobile branded devices have unlimited roaming on USC.

Get the SIM and IMEI whitelisted and there will be no difference at all.
Domestic Roaming (US Cellular) Communism | T-Mobile Community
It has taken me almost a year to find out from T-Mobile why my girlfriend isn't able to ro on to the US Cellular network when visiting Beckley, West Virginia. The reason is truly shocking. It is because her Samsung purchased S9+ was not purchased from T-Mobile or Metro. It doesn't matter that...
