What is 2G 3G network and what does 2G network mean

2G network is the second generation of network communication technology, which uses digital signals for network communication, which greatly improves the call quality and communication system storage capacity.

Most of the mobile phone networks used now are 2G networks, such as the SIM cards of China Mobile Unicom are used 2G networks, and now 3G networks are developing, but it is estimated that it will take some time to become popular. The G of 2G and 3G means "generation", that is, the second-generation communication technology and the third-generation communication technology, and the difference is mainly in the network speed.

Advantages of 4G over 2G:

1. The Internet is fast, and the network speed can reach 150mbps.

2. Stable speed: There is a double guarantee of 150M of 4G network and 42M of 3G network, and the speed is stable.

3. Wide coverage: China Unicom is accelerating the construction of 4G network and will focus on improving the coverage of hot spots.

4. Excellent tariff: China Unicom 4G** is rich in types, voice and traffic are at a price in China, and ice cream has been launched**, traffic can be used with confidence, saving money and worry.

<>Summary:2G network refers to the second generation of network communication technology, 2G network supports **, SMS, MMS, and very slow Internet access. Switch from a 2G network to a 4G network, and perform the following steps:

Dear, hello, I am glad to answer for you, 2G network means the second generation of mobile communication technology, the full name is second generation, often also known as digital cellular network. It is a new type of digital popularization mobile communication technology launched after the analog bee network (1G network). The 2G network uses digital communication technology, which can provide better speech sensitivity and data transmission quality.

It can support simple text messaging and basic data transfers such as email, web browsing, etc. Compared with 1G networks, 2G networks use more efficient channel allocation methods to support more users to communicate at the same time. Now, 2G networks have been gradually replaced by more advanced and faster network technologies such as 3G, 4G, and 5G, but in some remote areas or some developing countries, 2G networks are still the main mobile communication technology.
