After doing some work on wifi such as browsing. The network signals just goes off in my JB updated xperia P and it shows no SIM inserted. After that I switch off and then switch on my phone the signals reappear. Can someone help me with this.
How is your phone signal set?(GSM,WCDMA or GSM/WCDMA(preferred))?It could be on the last one,and the signal is not very good,thats why you lose the signal sometimes.
Turn off your phone, take out your SIM card and insert it again into the phone. If you still have the same problem you can try with another sim card and see if that makes any difference.
