Why can't I make or receive calls on my Sharp Cell Phone?
- KKristin HardyAug 16, 2025
If your Sharp Cell Phone is not making or receiving calls, there might be several reasons: * If a “SIM card error” message appears, your SIM card may be damaged. Contact your dealer or network service provider. * Check your call barring, fixed dialling, remaining battery, and call forwarding settings. * Ensure your phone isn't performing data communication via Infrared (IrDA), Bluetooth, or USB Data Cable. * If using a pre-paid SIM card, check your remaining balance.
