Xiaomi mobile phone can't receive Google verification code

Xiaomi mobile phone can't receive Google verification code. Cause: The mobile phone or mailbox may be broken. Check whether the mailbox is full. If yes, please delete some information. I still can't get it after deleting it. I suggest you change your mobile phone or card, and test whether it is due to hardware, whether it is intercepted by mobile phone interception software, whether the mobile phone signal is normal, and try to test whether it can be received in other places.
