Why can't I call or send a message?

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

1. Check whether the mobile phone is in arrears, and suggest to pay 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. If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether the number has been roaming;

5. Try restarting or changing your mobile phone to see if you can answer the phone;

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

If your mobile phone can't send short messages, you can try to restart or change your mobile phone to test whether there are any of the following situations:

1. The SMS center number is set incorrectly, please re-enter the correct SMS center number;

2. No signal or low battery;

3. Because the system is busy during the holiday short message sending peak period, it is suggested that you try again later or avoid the sending peak period;

4. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number;

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9. SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
