I switched to TMobile about three months ago
All of a sudden I am not getting calls ...They are going straight into Voicemail

When I realized this I looked and they were in a place on the screen Blocked Voicemails

They are not blocked numbers

I had Apple look at my phone and have been dealing with TMobile to no avail

They want me to buy a new phone and I am not going to

Apple says its their network and they say its Apple

Anyone else have this issue
