Apple 5s changed the id password, and the mobile phone could not receive 163 email to send SMS.

Hello! If you don't receive SMS or verification code, it may exist in the following situations:

1, check whether the mailbox is full. If it is full, please delete some information;

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

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