CHUWI shows their new V99X ultra-thin 7.8mm 9500mAh 9.7" Retina with an empty 3G module by Huawei slot, so you can turn your Wi-Fi only tablet into a 3G and even next year into a 4G LTE tablet by simply adding the networking module that you would like to add into that slot. Maybe a White Spaces 700Mhz module can be possible also. The perfect optional cellular expansion system for the Rockchip RK3188 in my opinion, and this CHUWI V99X Retina 9.7" RK3188 tablet looks really good!
