Can't SF get short messages in the same city?

What the subject wants to ask is "Is there a reason why Maotai didn't get the verification code when it arrived?" The reasons are as follows.

1. Wrong mobile phone number: The mobile phone number provided to SF is wrong, which makes it impossible to contact me for verification.

2. SMS is filtered: the mobile phone misjudges SMS as spam or filters it to other folders, resulting in mistaken recognition as not received.
