Can't send text messages online

1. According to the information you provided, if your mobile phone can't connect to the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you won't be able to use the Internet function normally;

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. Check whether there is any telephone charge in the account. If the balance is insufficient, it needs to be recharged before use;

4. Confirm whether the parameters of the mobile phone have been set;

5. Check whether the USIM card is inserted. If it still cannot be used after being plugged in, it is recommended that you go to the business hall to check whether the USIM card is faulty or change the card for testing.

6. Check whether there is anything wrong with the mobile phone. It is recommended that you change the machine for testing.

7. If your mobile Internet access reaches its peak in the current month, the system will automatically turn off your data functions such as Internet access, MMS and mobile newspaper, and turn them on automatically in the next month.

The above situation has not been solved, you can contact the local manual customer service for handling.

2. If your mobile phone can't send SMS, you can try to restart or change your mobile phone for testing and check the following reasons:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number (+861301012500 or 0086 130 165438).

2. There is no signal or the battery of the mobile phone is low;

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

4. The sending format is incorrect. If you send SMS 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.
