Apart from calling IDD from your hotel room, there are various phone cards available in post offices inside hotels or at most newsstands on the street in China. Among them IC card and IP card are the most popular ones.
Most public telephones you see in booths are IC telephones, which allow you to call home directly. IC card is issued by China Telecom; international calls with IC telephone cards are relatively expensive, usually over 10 RMB/M.
When you buy an IC card and want to call back home, simply just find a telephone booth either in hotel, restaurant, airport or some other places, insert the card into the phone, follow the vocal instructions to dial the number you want.
IP cards are issued by different issuers such as China Telecom, China Unicom, China Netcom and China Jitong, thus the Rates for international calls are different. China Unicom's rate for calls to Hong Kong, Macau and Taiwan usually is 1.5 RMB/M, 2.6 RMB/M to America and Canada while 3.6 RMB/M to other countries. The others' rates for international calls are either a little bit higher or lower than that of China Unicom.
Currently, the IP phone service has covered the whole country, providing international service between China and over 200 countries and regions. There will be instruction on each IP card to tell you how to make a call, you can use the hotel phone to call with IP card and the hotel usually will charge some fare as that of city call.
Please note: some of the IC cards or IP cards can be used only in certain provinces or regions, so please check it and also the expired date before you purchase them.
