Why is there no SMS notification for changing mobile phones?

To change the mobile phone binding, you need to unbind the original number before binding the new number, so you need the original number to receive the SMS first. If you confirm the above relationship, you still can't receive the text message. Please refer to the following:

1. Network delay, try again later;

2. If the signal is not good, change to a good place to receive it;

Please make sure that the mobile phone number is entered correctly.
