Why can't I make or receive calls on my Sharp 770SH?
If your Sharp Cell Phone is unable to make or receive calls, verify that the message “Insert SIM card” is not displayed. If it is, your SIM card may be damaged. Also, check your call barring and fixed dialling settings, remaining battery, and call forwarding settings. Ensure your phone isn't performing data communication via Bluetooth or USB, and check your balance if you're using a pre-paid SIM card.

If your Sharp Cell Phone rejects the PIN or PIN2 code, double-check that you have entered the correct code, which should be 4 to 8 digits long. Note that after three unsuccessful attempts, your SIM card or protected functions will become locked. If you do not have the correct PIN code, contact your SIM provider.
