For some locked SIM cards , contract SIM cards which operators don't allow to use on wifi routers , or only allow to use on their authorized devices . This product might not work. (IF your SIM card can not acce to Internet ,pls don't be panic .usually you change another operator's universal SIM card ,then it will work .Or you can contact us for help .) 5.Knowledge about 4G speed . in practical daily use , 4G WiFi router usually would provide 3 - Mb/s download speed for WiFi users .it's enough for ordinary users to watch video ,play games ,etc smoothly . Router's 4G chipset top capacity is 300M , and 4G base station's theoretical top speed is 300Mtoo .however the 4G base station provide service to many 4G users at the same time , instead of giving full 300M bandwidth to one user , and 4G signal strength , SIM card limitation and environment would affect the network speed too .IF some ignorant user eager for top theoretical speed , compare the speed of the phone(which is more expensive than router), and love to use inaccurate APP or software to test network speed , pls don't buy . no product on market would meet such requirements .
