Confirmation information

Confirmation SMS is generally a goodwill reminder automatically sent by the operator when the mobile phone user wants to order a certain charging item, with the purpose of reminding the user of the tariff.

There are also some standard charging SP, when users want to order services, they need to reply SMS twice to confirm the service order, so as to avoid unreasonable charge deduction caused by misoperation.

As long as there is no reply confirmation information, the service will not be ordered.
