Hi guys, I need your help with a Samsung Galaxy Grand Prime SM-G530W smartphone. This phone has a clean IMEI/ESN and it is unlocked. The problem with the phone is that the phone reads the SIM card but the screens says "No Service" and the Signal meter only shows a No Signal circle with a crossed line on it. The phone does not make phone calls at all. I tried to enter the Service Mode but that function does not work. Please guys helpppp!!
