I couldn't get the verification code on my original mobile phone number in Changsha.

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

2. Incorrect input of receiving number. Check the input receiving number, and if it is wrong, please enter the correct receiving number.

3. System failure of product service provider. If you just can't receive the short message with verification code, other short messages can still be received. You can contact the product service provider that issued the verification code for feedback.

4. Other reasons. If the above three problems are not solved, you can contact Unicom customer service for help.
