I can't dial the number, and I can't reply to the text messages.

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.

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

2. If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if there are any of the following situations:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number.

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

3. 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 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.
