The text message shows the regional error.

If the mobile phone can't send short messages, you can troubleshoot according to the following conditions:

In case 1, the number of the short message center is set incorrectly. Please reset the correct number of the SMS center.

1, different mobile phone models have different setting paths, so it is recommended to check the mobile phone manual.

2. Different mobile phone numbers belong to different places, and SMS center numbers are also different. For example, the number of Shanghai Unicom SMS Center is+8613010314500, and that of Beijing Unicom SMS Center is+8613012500.

In the second case, if there is no signal or the signal is poor, you can go to a place with strong signal to test.

In case 3, the SMS sending function is turned off, so you can turn on the SMS function and try again.

Case 4 is blacklisted by SMS and can only be used normally after going to the business hall to remove the blacklist.

In the fifth case, the balance of the number is insufficient, so you can pay for it and try again.

Situation 6: There is something wrong with the mobile phone, so you can change the machine for testing.

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