The mobile phone can answer the phone and send text messages, but the phone can't be dialed out. Dialing display is limited by fixed dialing! How to solve

Enter the dial-up interface, press the menu button to enter the settings, drop it down to the bottom, enter more settings, call status and identification-just turn off the fixed dial. As long as the SIM card is loaded, the phone is already set by default. Is it because you don't have Internet access and it has WI-FI function? If you enable it, you will not be able to access it. Maybe there is something wrong with the mobile phone. You can ask someone to get it for you where you bought it.
