What should I do if my mobile phone can't receive the verification code SMS?

Unicom customers can't receive SMS verification code on their mobile phones for the following reasons:

1, mobile phone settings. The mobile phone comes with interception or downloads the APP to intercept, please check the settings of the mobile phone to solve it.

2. An error occurred when entering the receiving number. You can enter the correct receipt number to solve the problem.

3. If only the short message with verification code cannot be received, other short messages can still be received. You can contact the product service provider that issued the verification code for feedback.

4. If it still can't be solved, you can contact the customer service of the number operation for help.
