If the signal used to be good, the phone suddenly becomes no signal. In addition to the cause of the base station damage, be sure to pay attention to the fact that the signal around the area where your mobile phone is located is likely to be shielded. There are a number of signal jammers on the market. These devices, when turned on, emit radio waves that interfere with cell phone communications. This will result in our mobile phone can only receive useless interference waves, but can not receive the normal base station signal, resulting in no signal.
