4G LTE Module

In order to ensure that users can play games anytime and anywhere they want, the WIN 4 uses an extra back-mounted 4G LTE module that supports4G TD-LTE, FDD-LTE, and 3G CDMAnetworks, as well as aNano-SIM card. The module is not a standard but an optional feature. When needed, attach the module to the back of the device! Similarly, WIN 4 may also provide back-mount modules supportingM.2 2230 or 2242 SSDto make it easier to extend storage.
