We had this Mts network with us this was quite comfortable and we can take it wherever we go.
It has good speed, easy recharge options, and good range in our area Thrissur, kerala.
Also it displays the network range in it and u can use it in any laptop or system even while travelling and all u need to know is the username and password.
Also it has an adapter with it so u dont need any system for wifi connection, u can simply plug in and use it.
