Why can't I send a message by phone after charging the phone bill?

If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if the following conditions exist:

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

2 No signal or insufficient battery power;

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 SMS sending time exceeds 24 hours;

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

7 blacklisted by SMS;

The balance of number 8 is insufficient;

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.

According to the information provided by you, the common reasons and solutions of the phone's failure to answer the phone 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. 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;

5 try to restart or change your mobile phone to see if you can answer the phone;

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

The above situation remains unresolved. It is recommended to contact the Unicom customer service to which the number belongs.
