this is a 4G wifi dongle which means u just need to put any 4G sim in it, and connect to pc for that pc to instantly connect to internet. otherwise, u can plug it into any usb outlet, and it works as wifi using data from the 4G sim. so u can plug it into a phone charger and connect all ur phones and devices to the internet via wifi!

this one has special feature that it supports micro SD card, so u can put one SD card in this dongle, any any computer or mobile connected with it can login with admin password to download the files in ur SD card(no data is used for this feature, u can use it without sim also)

comes with dongle only, I will give link to pdf manual when u purchase
