I got my mint mobile phone and plan set up a couple weeks ago. My friend has been trying to call me, but it's not even in my missed calls log. She said it goes dead silent and doesn't even ring when she's calling, and then goes straight to voicemail.
I'm waiting on medical testing results that determine if I can go back to work or not. It is VERY IMPORTANT that I am able to receive calls. How can I resolve this issue?
