I'm having a network problem with my Samsung Galaxy Young (S6312) device. Sometimes while trying to make a call, even though the signal indicator shows 2 or 3 bars, the device displays a message like "Not registered on network" and the call doesn't get through.
Also, sometimes while my mobile data is turned on it doesn't connect to the internet. I have set the mobile network to the GSM/WCDMA(AUTO) mode.
Is there any solution for this?
