How much will it cost per month if I open the missed message reminder service of Telecom?

The service fee for missing message reminder consists of information fee and communication fee, which is charged to the called user. 1. Monthly users will be charged 2 yuan/monthly information fee (monthly information fee will be deducted at the beginning of the month). 2. When the user uses the missed call reminder service, all uplink instructions (when the user sends uplink instructions such as registration, restart, cancellation, etc.) are normally charged a communication fee of 0. 1 yuan/piece; 3. Although the missed call reminder service is realized through call transfer, registered users do not charge this part of the call transfer fee. 4. When the user dials 1 18388 to customize, activate or cancel the missed call reminder service, the calling user will be charged according to the current tariff standard. (Call 1 18388 directly in the province of origin to collect local telephone charges; Roaming places in the province directly dial 1 18388 to collect roaming charges.
