In the 4g state, short messages are sent in the 2g network.

Don't worry, just because the coverage of 4G is not as wide as that of 2G, if SMS goes from 4G, you won't need SMS if there is only 2G signal but no 4G signal. After the wide coverage of 4G, voice, network and so on can be above 4G, and then 2G will be gradually eliminated ~ ~
