If you cannot make or receive any phone calls, please follow the steps below:
Check the Auto-reject list to ensure that there are no numbers currently set to auto-reject. If the number is not in the list, please proceed to the next step.
Disable any apps installed on your device that may have features for blocking or rejecting calls.
Network Service Provider:
There may be issues with the network or possible scheduled maintenance happening in your area. Contact your service provider to see if there are any issues with your service. If your service provider confirms that your service is stable, please proceed to the next step.
If Flight mode has been enabled, you will not be able to receive or make phone calls, send or receive text messages or access your mobile data. This is because Flight mode restricts all network connections to your mobile device to avoid any interference with sensitive equipment. If Flight mode is disabled and the issue persists, please proceed to the next step.
Please ensure that it is not just a specific contact that you cannot make a phone call to.
Power off your device, and then remove the SIM card. If your SIM card is dirty, please gently clean it with a dry cloth. Carefully check to see if there are any scratches, or any damage to your SIM card. If your SIM card has been damaged, contact your Service provider for a replacement SIM card if required.
