Who I have the same questioned this topic

My calls arent going through. Everytime I try to call a number, I just hear silence, no dial tone or ring tone... nothing. And the call never goes through.. What is going on? Ive powered on and off, tried it in safe mode (no idea how i even got the phone into that mode) BUT texting/web everything else works fine! What is the problem??

Also when someone calls me, i answer and theres just silence and then it drops the call two seconds later.. I have full service
