It maybe problem of the phone, network, or your settings, Please perform the following checks:
Make sure you have dialed a valid number and press the pick up call key.
Make sure your mobile phone is connected to a network, and that the network is not overloaded or unavailable.
Check your subscription's status with your service provider.
If the problem persists, please try the following steps:
Check if you had activated call barring. 'Call barring' means you had barred some out-going call (All calls, All calls except those in SIM contacts, International calls, International except home) or incoming call (All calls, All calls except those in SIM contacts, Roaming). If you had activated, please cancel it.
Check if you had activated flight mode. 'Flight mode' means you had disconnected with service provider, and you will not be able to make out-going call and can't receive call. If you had activated, please cancel it.
Check if you had activated 'call forwarding'. It is possible that your incoming calls will be forwarded directly to your voicemail or other phone. If you had activated, please cancel it.
If the problem still can't be solved, please bring your phone to an Alcatel Care point for inspection, or call the Alcatel Contact Center correspondingly in the country you are located
