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 supports 4G TD-LTE, FDD-LTE, and 3G CDMA networks, as well as a Nano-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 supporting M.2 2230 or 2242 SSD to make it easier to extend storage.
