How much is the landline value-added service fee?

This is some additional services handled by operators (China Mobile, China Unicom, China Telecom) except SIM cards, such as GPRS Internet access, SMS package service, weather forecast, caller ID, color ring back tones and other services. Many SIM card services now include these. Some value-added services are good. If you don't use these value-added services, such as GPRS, you will waste a lot of money, so you won't waste it if you handle it within the prescribed scope. In order to further improve the service level of telephone charge information, China Mobile has standardized the telephone charge information, and listed such items as call forwarding, GSM, SMS, voice SMS, MMS, GPRS traffic, caller ID, mobile phone newspaper and color ring back tone under the column of "value-added service fee".
