This 3G wireless router is a device which converts the 3G data of your sim card to a wifi hot spot around you so that other devices like laptop mobile and tablet can share it.
I had chosen this device against my phone because my phone battery dies fast when I use hot spot in it.This 3G wifi router has 2000 mah battery and I can use this device efficiently while travelling.
On a full charge I am able to use this device continuously for 6 hrs which satisfied me a lot.The setup process is also an easy one and it gives the same speed of mobile 3 g speed.
Only issue it has is it gets heated if you use for a long time.Overall this device is satisfied me and it is a value for money.
