What does QQ mean by showing 2G online?

1. If the mobile phone operator is a 2G service network, 2G online will be displayed. Similarly, some will be 3G, some will be 4G, and some will be WIFI. It varies according to the network signal environment of friends.

2. It is also possible that the network signal is poor, and now it has been upgraded to 4G. If 2G is displayed, it means that your friend's network is in 2G network, where there is no 4G signal, so this will happen.

3. After the associated QQ number is enabled, the associated account will be displayed as 2G online status.

2G: Digital network. Different from the previous generation, the second generation mobile communication technology uses digital transmission instead of analog, which improves the efficiency of telephone network search. During this period, the number of mobile phone users increased rapidly, and prepaid mobile phones became popular.

The establishment of a large number of base stations shortens the distance between base stations, reduces the coverage area that a single base station needs to bear, and helps to provide higher quality signal coverage. Therefore, the receiver does not need to be designed as a high-power and compact mobile phone as before.
