I have Nokia lumia 520 and windows 8.1 for a while now. Suddenly I began to experience difficulties in browsing and I thought it was the network but now every time i want to make a call, when I launch the call either it does not ring or it says system busy.

Please how to solve that ? I called my provider and they said I have to check my phone, that the problem is with my phone.
