Meizu M9 used a mobile 2g card in the dormitory, and suddenly she couldn't find the signal. In other parts of the school. ...

Compared with M8, M9' s mobile phone has a certain improvement in signal, which is no longer the main crux of the mobile phone, but its signal strength will be weaker than that of the old mobile phone and similar to that of similar smart phones, but it will hardly affect its use. In your case, either there is something wrong with your base station or your mobile phone is broken! My M9 doesn't have this problem. I can't get a signal, and other people's mobile phones can't get a signal! Take the elimination method, if it is a mobile phone problem, just send it for repair!
