The tariff standards are different in various places. The speed is very fast, but the tariff is relatively expensive. You can see it on the website of each provider. It is not necessarily a traffic-based one, but there are also monthly and time-based ones. However, most of the traffic occurred on World Telecommunications Day on May 17, when China Unicom announced the launch of trial commercialization of 3G services. So far, my country's three major operators have all launched 3G services, and their 3G tariffs have also been released. Many users generally believe that the tariffs of the three operators are "too expensive". For this reason, we compared the tariff levels of the 3G special services "wireless broadband" and "video calls". Standard rates for mobile phone voice: China Unicom: 0.36 yuan/minute; China Mobile: 0.4 yuan/minute; China Telecom: 0.4 yuan/minute. The 3G rates include the rates for 3G mobile phones and wireless broadband. In terms of 3G mobile phone tariffs, China Unicom adopts the structure of "3G basic package" + "3G optional package". Among them, the "3G basic package" is divided into 7 levels according to price, ranging from 186 yuan to 1686 yuan. China Mobile announced that its 3G mobile phone tariffs will be integrated into the Global Telecom package tariffs. China Telecom's 3G mobile phone tariffs start from the lowest monthly package of 49 yuan, which is divided into business packages, chat packages, mass packages, fashion packages, etc. In the standard call rates, the basic monthly rental fee for 3G mobile phones of the three major operators is 50 yuan. Local calls to China Mobile and China Telecom cost 0.40 yuan per minute, and calls to China Unicom cost 0.36 yuan per minute. Incoming calls are free. Domestic roaming charges are 0.6 yuan per minute for making calls, 0.6 yuan per minute for receiving calls, and 0.4 yuan per minute for the other two companies. Video phone rates China Mobile: 0.6 yuan/minute China Unicom: 0.9 yuan/minute China Telecom: Video calls are not supported. In the video phone part of the standard tariff, local calls from China Mobile are 0.6 yuan per minute, and calls are free. Domestic roaming calls are 0.9 yuan per minute, calls are 0.6 yuan per minute, and domestic long-distance calls are 0.1 yuan per 6 seconds. China Unicom's video phone service costs 0.9 yuan per minute for local calls and free calls, 1.2 yuan per minute for domestic roaming calls and 0.9 yuan per minute for calls, and domestic long distance charges are 1.2 yuan per minute. China Telecom currently does not promote mobile video calling services. After the wireless broadband exceeds the tariff, Mobile: 0.01 yuan/KB, with a cap of 500 yuan. China Unicom: 0.01 yuan/KB, with a cap of 800 yuan. Telecom: 0.05 yuan/minute, with a cap of 1,000 yuan. In the 3G era, the launch of 3G wireless broadband is the business with the most mature demand. It is also the main business promoted by the three major operators at present, and this field has already been booming. China Mobile's G3 traffic packages are divided into 4 levels: the 50 yuan package can cover 500M traffic per month, the 100 yuan package can cover 2G traffic per month, the 200 yuan package can cover 5G traffic per month, and the 300 yuan package can cover 10G traffic per month. (Only applicable to G3 netbooks, not applicable to G3 network cards). China Unicom's 3G wireless broadband packages are billed based on traffic flow, which are 150 yuan/month for 3G, 200 yuan/month for 5G, and 300 yuan/month for 10G. The excess is 0.1 yuan/MB. China Telecom’s wireless broadband business adopts a charging-by-time model. The tariff packages include: 160 yuan per month includes 300 hours of local and 5 hours of domestic roaming Internet access; 200 yuan includes 200 hours of Internet access (regardless of local and roaming); 300 yuan includes 360 hours of Internet access per month. Hours of Internet access (regardless of local and roaming)
