Why can't WeChat send short messages?

1, there is something wrong with the mobile phone network. First, check whether the data switch is off, then check whether there is no traffic on the mobile phone, and whether the network signal of the mobile phone is poor, which will lead to the mobile phone being unable to connect to the network, and of course, it will be impossible to log in to WeChat.

2. WeChat itself. Sometimes the WeChat server needs to be updated, or the WeChat server encounters a large-scale attack, and WeChat may suspend its service. At this time, you can't log in to WeChat. Generally, it will recover after a while.

3, program problems, if the version of WeChat in your mobile phone is too low or suffers from virus damage, then WeChat is definitely unable to log in. At this time, you need to uninstall WeChat and reinstall it. All right!
