I'm a Verizon customer looking to leave the world of locked, contracted phones. So I am really excited about T-Mobile and am shopping for Android phones for the family.
The WiFi calling feature would be essential for us. My question, must my phone come from T-Mobile to support that? Example 1) unlocked (Google) Nexus 4; 2) unlocked Samsung Galaxy S3 Mini.
thanks in advance for the clarification!
