Why can't I receive the message when the railway is charging?

Distance and interference, binding problems and other reasons.

1, distance and interference: the distance between the tower and the antenna is far, and the interference of the surrounding buildings affects the cell phone signal, so it is impossible to receive the SMS verification code.

2. Binding problem: The tower charging pile is not correctly bound to the user's mobile phone number, which makes it impossible to send SMS verification code to the user.
