My cool God f2 has a signal to surf the Internet but can't make phone calls or send text messages. How did this happen, didn't it?

The common reasons why mobile phones can't answer calls and their solutions are as follows:

Method 1: check whether the mobile phone is in arrears, and suggest paying for recharging;

Method 2: Check whether the mobile phone is set with call forwarding, airplane mode on and call barring. It is recommended to cancel and try again.

Method 3: check whether the function or signal of the mobile phone is normal, and suggest changing the mobile phone or trying again;

Method 4: If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether roaming permission is enabled for this number;

Method 5: try to restart or replace the mobile phone to see if you can answer the phone;

Method 6: Take the mobile phone card to the local business hall for testing or replacement.

The processing method that the mobile phone cannot send short messages is as follows:

Method 1: You can change your mobile phone and see if you can send and receive short messages.

Method 2: If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it.

Method 3 If not, I suggest you check whether there is a problem with the sim card;

Method 4: Check whether the number of SMS center is set correctly;

Method 5: Take the mobile phone card to the local business hall for testing or replacement.
