If you are not receiving the verification code on your phone for your Microsoft account, there could be several reasons for this issue. Let's go through some common troubleshooting steps to help you resolve the problem

If you don't immediately receive the security code, the delay could be due to issues with your wireless carrier or Internet service provider. Here are some things you can try:
If you used an email address to get the code, check your junk email folder.
Try to wait a little longer. Some carriers process requests slower than others.
If you still don't receive the code, please use another security contact method associated with your account to obtain the code.
Note If you request a new code, the one previously requested will become invalid. If you enter the previous code, you will receive an error message stating that the code is not valid.
