Htc 802w can't send a short message card, which is a good mobile phone problem.

Hello, I suggest you try the following operations.

1) Please restart your phone and try to send a message.

2) Please ask the network operator whether the status of point-to-point SMS service is normal and whether the number of SMS service center is set correctly.

3) It is suggested to borrow a card or put it in another mobile phone to try. If the card is invalid, please bring your ID card to the online business hall for replacement.

4) Try to send short messages in different places to avoid regional signal failure.

5) It is suggested to uninstall the third-party SMS platform software in the mobile phone and restart the mobile phone to try to send SMS.

6) It is recommended to back up the data of the mobile phone and try to use it again after restoring the factory settings.

7) If it still doesn't work, it is recommended to back up the data of the mobile phone, bring the invoice card and send the mobile phone to HTC repair center for testing.
