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

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

1. The mobile phone is down or the account is cancelled due to arrears. You can log in to China Unicom APP to check the status of your mobile phone number.

2, mobile phone settings. Please check your phone settings, because it comes with an interceptor or an application you downloaded yourself.

3. Incorrect input of receiving number.

4. 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.

5. If it is still unresolved, you can contact the customer service of Unicom where the number belongs for help.
