    I have a Verizon branded SamsungGalaxy S6.  I switched to T-Mobile and the T-Mobile store configured all my APN settings. However, rI can only use voice or data, but not both at the same time.  As soon as a voice call is being sent or received, the data connection goes away.  Once the call is over, the data connection returns to full strength immediately.  Please help!
