The city has an advanced telecom infrastructure. Public telephones can be found on most downtown streets. Mobile operators support GSM and CDMA cell phones. Most office buildings have Internet connections and Internet cafes are almost everywhere. China Telecom is the biggest fixed-line telecom operator, including public telephones, fixed phones in the office and broadband connection at home and work.

China Mobile and China Unicom are the two mobile operators. China Mobile has an extensive GSM network while China Unicom supports both GSM and CDMA cell phones.


The mobile network is very extensive and powerful in Beijing. Signals can even be found in the metro and in many elevators. Both GSM and CDMA cell phones have networks. The city supports high-speed wireless networks based on GPRS and WAP, but 3G networks are still undergoing tests.

How to apply

Here, it's better for you to buy a flexible card, which enables you to top up your account at any time. All the mobile outlets sell such prepaid sim cards. Yitong card and Jiajia card offer the international call service. Both of the cards are the prepaid kind.

You can top up your mobile phone either with top-up vouchers which are available in all mobile outlets, grocery stores and newspaper stands.

China's two mobile operators
Many mobile outlets in the city look more like stalls. They sell mobile SIM cards, top-up vouchers and even rechargers for most phone models


It's very easy for a foreigner to find an Internet café on street as they have obvious signs.

Internet cafés usually charge 2-5 yuan (25cents to 62cents) per hour. The charges vary, based on the computers' configuration.

The campus dorm provides university network connection, through which you can log on normal internet. It charges RMB60/month for such service.

Don't be frightened by its crude façade. Most Internet cafés in Beijing don't have pleasant conditions, but they charge very low. Remember the Chinese characters
"网吧" for Internet café.

Warning! You can't just simply pick up a phone in the city and call home. You need to buy an IP card. They're cheap and widely available at grocery stores and post offices. But IP cards aren't suitable for every phone but usually, you can use IP cards through fix-lined phones and cell-phones.
