New Phone not Connecting to T-mobile Network

Hola,

 

   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"

    I bought it as T-mobile's main band for LTE is 4, which the phone supports. SO it is supposed to work, right? 

     

    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.

    4G Network : FDD-LTE 900, 1700/ 2100, 1800, 2100 MHz (Band 1, 3, 4, 8)

    Of these, T-Mobile in many places will only have GSM 1900 and LTE band 4 and the GSM 1900 is intended only to support legacy M2M (e.g. alarm) systems.

  • What little I can find online says that phone has the following bands:

    2G Network : GSM EDGE 850, 900, 1800, 1900 MHz
    3G Network : UMTS HSDPA UMTS 900, 1700/2100, 2100 MHz
    4G Network : FDD-LTE 900, 1700/ 2100, 1800, 2100 MHz (Band 1, 3, 4, 8)

    Of these, T-Mobile in many places will only have GSM 1900 and LTE band 4 and the GSM 1900 is intended only to support legacy M2M (e.g. alarm) systems. This phone is a very poor choice for use on T-Mobile in 2022.
