Why can't mobile phones send text messages and make phone calls, but they can surf the Internet?

First, the common reasons why mobile phones can't answer the phone and their solutions are as follows:

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

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

3. Check whether the function or signal of the mobile phone is normal. It is recommended to change your mobile phone or location and try again.

4. Try to restart or change the phone to see if you can answer the phone;

5. Bring the mobile phone card to the local business hall for testing or replacement.

Second, if the mobile phone can't send short messages, you can troubleshoot according to the following conditions:

In case 1, the number of the short message center is set incorrectly. Please reset the correct number of the SMS center.

1, different mobile phone models have different setting paths, so it is recommended to check the mobile phone manual.

2. Different mobile phone numbers belong to different places, and SMS center numbers are also different. For example, the number of Shanghai Unicom SMS Center is+8613010314500, and the number of Beijing Unicom SMS Center is+8613012500.

In case 2, if there is no signal or the signal is poor, you can go to a place with strong signal to test.

In case 3, the short message sending function is turned off, so you can turn on the short message function and try again.

Case 4 is blacklisted by SMS and can only be used normally after going to the business hall to remove the blacklist.

In case 5, the number balance is insufficient, so you can pay and try again.

Situation 6: There is something wrong with the mobile phone, so you can change the machine for testing.

After the above reasons are eliminated, it still cannot be used normally. You can click /qAHfS for feedback, and we will check and handle it as soon as possible.
