VoLTE does not work, Incoming call going straight to voicemail.

ppnewaskar

    Hello,

     

    I recently moved my plan from ATT to t-mobile. I am facing following issues on my ATT unlocked Note 5 device.

     

    A lot of incoming calls get dropped. A lot of the calls that I get are getting dropped and they go straight to voice mail. Sometimes when the do come successfully then I can see that i am not able to use internet during the call. And this behavior is not consistent. I think this behavior depends on my location.

     

    I have tried turning of VoLTE on my device but the same thing happens.

     

    I have also tried setting my APN using this link -> Network, APN, and VoLTE: Samsung Galaxy Note5
