psl help me \



Thanks in advance.

Most probably your SIM card is the problem. Try changing sim card and share if it works with other SIM.

Try switching off and switching on the phone. Re-boot or initialize the cellphone, or power off and power on. The reason could be that the Sim is not being detected by the instrument and so the phone is behaving as though there is no Sim in it.
