Why can't my mobile phone receive SMS verification code and log in?

You can't receive SMS or verification code due to the following reasons:

1 You can check whether the mailbox is full first, and if so, please delete some information;

I still can't get it after deleting it. You can change the machine or card to see if it is a hardware factor.

After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problem does not exist, please contact the local manual customer service to handle this problem.
