It doesn't have band 13 for use on Verizon. T-Mobile's the most permissive carrier about accepting BYODs. Thank you so much for the guidance so far, I have learned a lot from this! The shop owner told me I can replace the phone with eitherKYOCERA KYF37 GRATINA2 4G WIFI KEITAI,orKYOCERA KYF31 GRATINA 4G WIFI KEITAI.He said they are compatible with Sprint'sbands for 4G 26 and 41(main is 25, but phone does not support band 25). so 2/3 bands compatible, excluding main one.Before I proceed with the replacement. Will they work if I buy a SIM/plan with Sprint with decent coverage?16Visto0likes0ComentariosRe: New Phone not Connecting to T-mobile Network

In any event, with only one 4G band for T-Mobile, it's not a good choice. Do you know any carrier I can use that is compatible with the phone's 4g?26Visto0likes0ComentariosRe: New Phone not Connecting to T-mobile Network

Unfortunately the test data submitted to the FCC is not very revealing and the user manual submitted with the test is almost entirely in Japanese and contains no information I could use to help you. I can't see how you can lock the phone in GSM mode to test if that will work. You shouldn't buy a phone based on wishful thinking. There are too many ways for them to not work or work poorly. There was a time when I only bought unlocked phones from overseas. That was then, this is now. Our current two main phones came from T-Mobile and the backups are types known to work with T-Mobile before they were purchased. thank you for your help and effort. I will try and see if I can return the phone, or get a replacement for a phone that works with t-mobile.18Visto0likes0ComentariosRe: New Phone not Connecting to T-mobile Network

The phone also has to support T-Mobile's VoLTE system which is not stated in the specs I saw. Unfortunately compatibility of BYODs is entirely the responsibility of the customer. Maybe if you could provide the FCC ID of the phone I could research it some more. The FCC ID is an alphanumeric code about 7-9 digits long like "R7BJ6U43". It's found either on a sticker or in the Govt Info page in Settings menu. I finally found the FCC ID, it is JOYYKEA6022Visto0likes0ComentariosRe: New Phone not Connecting to T-mobile Network

Hello, I bought a new phone, the Kyocera 702KC. It is fully unlocked and when I popped my SIM in, it gave me a bar and I attempted to make a call, in the middle of the ringing, I got disconnected and can not join T-mobile again. I was told to set-up APN, but I do not know what to type in. When I go to network setting, and click on T-mobile, it says "can't connect to this network right now, try again later"Solved
