Ok, so I bought a note 8, unlocked, dual sim, unbranded on ebay. I had it on att, and it worked ok. I'm now on tmobile and it's being contrary. Signal and ability to make calls, text, use data are intermittent. Between great signal and still not able to do anything, and the otherwise expected great signal, great service, low signal, low service.

So I did some digging, and found out it may be due to the band that my phone is using. Which lead me to the possibility that it could have to do with where my phone is regioned for. My phone is regioned for united arab emirates. I am in the United States.

What can I do, and exactly, step by step, what do I need to do to make this work? I'm somewhat tech savvy, but have never attempted something like this before, though I am confident in my abilities with proper instruction.

Thanks in advance!
