My mobile phone can't send text messages and surf the Internet. what's up ...

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. 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.

If your mobile phone can't surf 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 phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

4, can be turned off for 3-5 minutes, restart the phone and try again;

5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

6. If the traffic reaches the peak in that month, the network will automatically shut down. We suggest you pay attention to our SMS reminder or inquire about the package product description.
