Everything fine but when your 3G signal is low e.g.- 1 tower then the router don't connect. So don't Panic .use a long data cable for connecting dongle. It's Support Universal dongles. 3G/4G,2G/3G only. not 2G only If u have 2G/3G then change to 3G mode it will work. Very fast in 4G and 3G.and it's support Reliance Jio 4G by connecting USB tethering . Yes it's work. And important part is don't Upgrade the router please. Once you Upgrade then Network Up down start.and you will be angry m sure.
