The verification code cannot be received

Question

Today is my second time to log in to my 365 account, and all account-related subscriptions have been activated. Everything was put into normal use yesterday, but today, when I was logging in as usual, I found that I could not log in using the verification code of my mobile phone, because my mobile phone could not receive the verification code. Later, I changed my mobile phone number, and this problem still exists. How can I solve this problem? I can't log in if I don't receive a verification code
