Because metal has a certain shielding effect on the signal, if the user uses a full metal cell phone cover, blocking the cell phone antenna, is likely to lead to poor cell phone signal and other problems.

Common causes of poor cell phone signal:

1, network problems or network can not be covered.

When the network coverage is bad, generally in the mountains, basements, elevators and shielding or signal interference, there will be no signal appearance or very weak appearance. Network in the debugging, optimization, maintenance process may also cause signal instability, the general network back to normal, the cell phone signal will return to normal.

Mobile phone signal amplifier can amplify the surrounding cell phone signal, so as to enhance the network quality. In some centered in a lower location of the neighborhood, basement users are very practical. The device mainly has an antenna, the antenna will be installed in the outdoor, the receiver can be placed in the home, the realization of the cell phone signal method, support China Mobile, China Unicom and China Telecom and many other cell phone network amplification.
