Thank you kirashi for the links! I have tried with several different Xfinity personnel to explain this, but the links you have provided have been a bigger help to me than anything they have told me. I can see some bands missing, so I think that explains it. EDIT: It looks like I am missing B46 and i think CAT9. Link to Xfinity's phone: https://www.xfinity.com/mobile/shop/phone/galaxy-s9ssplus-samsung?colorName=Coral Blue Thank you again for the links! I did not think that buying an unlocked phone would make a difference, nor did I think to look at the network bands.

Hello LTT Forums! My family changed service providers from T-Mobile to Xfinity Mobile, but when I tried to use my S9+ (purchased from Amazon as "factory unlocked" with Amazon as the seller), my IMEI comes up as incompatible. I was told it had to do with 3G or something by the rep, but their forums said that they do not accept any models with "U1" at the end. Is there anyone here who is knowledgeable in the field that can help me understand what is the truth? From what I understand, my S9+ is 4G LTE capable and is no different physically than any other S9+ sold by Xfinity or Verizon. Also, if I take my activated SIM from my new iPhone 7 and put it into my Galaxy S9+, will it work fine or will there be any issues? I was told by one rep that both phones would brick, and another told me that the quality on my S9+ would be lower than standard. I know this is the ultimate first world problem, but I saved up for the S9+ and I am really attatched to it. I appreciate any help and can offer any additional information as needed. Thank you.
