In the school dormitory, as soon as I entered the Wangwang 4G signal, it changed to H, but as soon as I exited, it returned to 4G. Is there a jammer? How to break?

Answer
If the school dormitory is equipped with a wifi jammer, then after you enter the dormitory, the mobile phone will not display a 4G signal. Because the wifi signal jammer is a fool-like device, it cannot be selectively blocked, and it cannot be blocked but the phone shows that it is not blocked. Your situation should be caused by a poor network signal.
