The message was sent successfully, but was not received. What happened?

Nowadays, many platform registered accounts need to bind the mobile phone number, and then click the Send SMS button to indicate that the SMS was sent successfully, but the SMS could not be received. This phenomenon is mainly caused by network reasons. Part of it is that the network signal is not good, which leads to the short message not being sent out, and part of it is because the server problem of the software developer is not sent out. At this time, you can choose another time to register and send text messages. When the network returns to normal or the server of the software developer returns to normal, you can receive the short message.
