Why can't the phone world card be charged with verification code or received?

The mobile phone is in arrears and the sending number is intercepted.

1. When the verification code is not received, it is mostly because the mobile phone is turned off due to arrears, and the verification code cannot be received normally.

2. The number that sent the verification code was blacklisted or intercepted by the security software in the mobile phone, which made it impossible to receive the verification code.
