Hello people. The time was using a SIM chip in my S3 but it only worked the data network and no phone calls. It displays the H + icon and access the internet without problems, but does not do phone calls, appear Mobile network not available.
So I changed my carrier and everything started to work until yesterday the same problem happened again. The IMEI number is correct.
I've tried going back to 4.0, 4.1.1 and 4.1.2 ... also tried to apply a patch that I can not remember the name and do md5 flash modem ... nothing worked .... what I do not understand is, I can access the internet without problems, but not the phone. Functioned smoothly, nothing stood in the current operator I'm using. can it be hardware?
