What are the detailed monthly charges for Zibo Mobile’s 3 yuan card? Is the call free?

Three-yuan card is an affordable mobile card. It charges 3 yuan per month for express and 3 yuan for all-time pass. This is fixed. The charging standard for text messages is 1 cent per message within the network and 1 cent per message between networks. Gross 5 cents. Local calls are charged according to the district (Zhangdian District, Zichuan District, etc.). Calls within the district are 0.2 yuan/1 minute, calls outside the district are 0.3 yuan/1 minute. Answering is free; long-distance calls are per minute. 0.3 yuan.

This is just what I know. I don’t know if it has changed now. You’d better go to the business office for consultation.
