NOTICE :
1.Our 4G router only support universal ordinary SIM cards . For some locked SIM cards , contract SIM cards which operators don't allow to work on wifi routers , or only allow to work on their authorized devices . This product can not work，you might see it connected to local 4G network , but you are not allowed to use Internet service . (IF your SIM card can not access 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 .)
2.Knowledge about 4G speed . in practical daily use , 4G WiFi router usually would provide 1 - 20 M/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 150M , and 4G base station's theoretical top speed is 150M too .however the 4G base station provide service to many 4G users at the same time , instead of giving full 150M 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 , and love to use inaccurate APP or software to test network speed , pls don't buy . no product on market would meet such requirements . Thanks .
3.We absolutely deliver exactly same device you saw on our website , however sometimes there might be some package diffidence on model name , manual book and box . Please refer to the actual product. Thanks
