Nantai Lake Vacation App mobile phone text message failed to send

Are you asking why the Nantai Lake Vacation app failed to send text messages?

1. The text message sent contained illegal content and special symbols, which were intercepted and forcibly blocked by the SMS bulk sending platform or the operator.

2. The channel for sending text messages is congested. This situation will occur during holidays or a certain peak period for text message sending. The operator's system channel is busy and the sending is delayed.
