- Check if the IMEI Number of the Mobile Phone is Good or Corrupt. To check the IMEI Number, Dial *#06#. If the IMEI Number is something like – 35826********220 OR *************??? OR ************000? OR ***************? Then the IMEI Number is Corrupt. Reload the IMEI Number to solve the SIM Problem.
- Check BSI Point of the Battery. The Middle Pin is the BSI. Change the Battery and Check. If the Display shows “Not Charging” and at the same time there is SIM Card Problem then it is caused because of BSI Problem of the Battery or the BSI Track of the PCB.

Could be SIM Problem or Software Problem. Insert another SIM and Check. If the same problem is still there then FLASH the Software.
