Unlocked ATT V35 working on T-mobile, but cannot send or receive SMS


    Hello everyone!


    I got an ATT unlocked V35 working with my T-mobile SIM. Calling is okay and I manually set the APN up and get LTE connection.

    But I cannot send or receive SMS.

    I checked the SMSC number is "+12063130004", 145 

    I also tried "+12063130004"

    But still cannot send or receive SMS....

    I also tried update with PDU format of SMSC, but got update error...


    Another problem is I can send MMS but not receive...I checked APN setting, it is same as T-Mobile instruction.


    Anyone know how to solve those two problems?
