Compatible with iOS 7, 8 and 9
Lock4GLTE is a toggle of flipswitch to Lock your cellular data signal on 4G as iOS automatically switch to 3G if 4G signal is too weak
Please note it may cause you unable to receive call if your carrier do not support VoLTE for iPhone
Also it may cause battery drain faster as iPhone had to increase it signal in order to receive a weak 4G signal
Turn off from ControlCenter before remove
