Just switched to Tmobile from ATT  - Galaxy s6 active - data and messaging works - unable to make/receive calls - please help

pjdell

    calls cant come in or go out when wifi is active

     

    with wifi off i can occasionally make an outbound call but takes close to 60 seconds to begin ringing (many times it never rings/connects)

     

    with wifi off i can occasionally receive an inbound call ...but it never rings and i am only alerted a call was missed or that i have a voicemail.

     

    I am aware that my s6 active is an att specific phone...I have been fiddling with apn changes from multiple forums but have had no luck in fixing this mess .

     

    please help

     

    thanks in advance
