What if Samsung's mobile phone can't make a call?

If the phone can't make a call, Samsung mobile phones generally recommend the following steps for investigation and handling.

Aircraft mode

Check whether the phone is in flight mode.

Signal instability

Check whether the cell phone signal is stable. If the network signal is not good or there is no signal, please turn it off and restart, and search the network again. If it doesn't work, it is recommended to take out the SIM card and try to insert it again.

Insufficient balance

Check whether the mobile phone has enough balance.

Fixed dialing number

If you can dial some fixed numbers, check whether the fixed dialing function is started. It is recommended to disable this feature. Note: When fixed dialing is disabled, the PIN2 code will be prompted. The network operator needs to query the password.

call barring

Check whether the call barring function is set. If so, please cancel and try to make a call.

Replace SIM card

Replace other SIM cards.

Restore factory settings

Back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings.

after service

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local after-sales service center for professional engineers to help you test.
