Abstract
Description
technical field
[0001] The present invention relates to communication technology, in particular to a network switching method, device, terminal and computer storage medium. Background technique
[0002] Networks of different standards may have different network quality in different places. For example, in a certain area, network A can be used normally, but network B has poor network quality and often drops. However, the opposite is true in adjacent areas. The B network can be used normally, while the network quality of the A network is poor. Unless the terminal card is replaced in each area, users can only choose A network or B network alone, and endure the difference in network quality brought by the same mobile network in different places. With the development of technology, terminals with dual cards appear. Users can manually switch networks according to the service of dual cards without uninstalling the SIM card of the terminal, so as to reduce network quality problems ...
