Why Shanghai paid communication services are deducted

Shanghai paid communication services are deducted because subscribers need to pay according to the service provider's pricing strategy when they use value-added services, information services, data traffic, calls and SMS, auto-renewal, and promotional activities.

1. Use of value-added services: Users use value-added services, such as watching video content, downloading music, and playing online games, which often require payment.

2. Information services: Users subscribe to information services, such as weather forecasts, news pushes, stock market quotes, etc., and these services will be charged according to a certain time period.

3, data traffic: when users use mobile data to access the Internet, they are charged according to the data traffic used. Data traffic is charged on a volume basis and also on a package basis.

4. Calls and SMS: Users who make a call or send an SMS, especially international calls and SMS, are usually charged according to the length of the call or the number of SMS messages.

5. Auto-renewal: Some services are set to auto-renew, whereby the service provider will automatically renew the subscription if the user does not actively cancel it after the initial subscription.

6. Promotions: During certain promotional periods, users are offered discounted rates, but after the promotional period is over, the fees revert to normal rates.
