I subscribed to a weather forecast service on my mobile phone some time ago, and then I received a "second confirmation" message from Hunan Mobile.

Well, it's not really interesting. The landlord need not think too much. If you really want to say why? This is an honest service launched by Hunan Mobile. The purpose is to prevent users from ordering services they don't like because of operational mistakes. After the user sends the first order request, 10086 will prompt the user to confirm. If the user does not get feedback, it will be regarded as "unsuccessful customization" and will not charge the user.

Is the landlord clear now? To put it bluntly, this service is entirely for the benefit of users, and there is no need for the landlord to have any doubts, so it is safe and practical.
