Text messages are always busy, but they just don't come out. The SMS function is not available. What's wrong with it?

1, check whether the mobile network is normal, because the information reception is incomplete and it can't be opened, especially if the signal or mobile phone is not very good.

2. Check whether the SMS storage service is abnormal.

3. Check other messages. Some text messages may have compatibility problems.

Second, the solution:

1. If only a few short messages can't be opened, there may be compatibility problems. Suggest that the other party try again.

2. If all the short messages cannot be opened, please try to clear the data after backing up the short messages.

3. Check whether there is a new version of the machine system and try to upgrade the system.

4. If it is invalid, back up the data in the machine (contacts, text messages, photos, etc. ) and try to restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the service center, and the professional after-sales engineer will help you test it.
