These are times I can not make or receive calls or text messages when I try to call there write "not registered on the network."
So I restarted my phone several times, do a restoration of setting, I searched my network manually but to no avail. I know this is not the problem from the SIM because I put it in another phone and I was able to call and receive my messages, so i concluded that it is the phone has a problem.
my phone works well but sometimes I have this weird problem
I hope you can help me I am disappointed, I thank you in advance
