I used to travel more and sometimes I need to be moved to some remote place because of work culture and I have been using this during my travel and when ever I tried to connect this dongle to my laptop, first it will throw an error cannot connect and after several attempts it gonna be the last time I used to be using it for 1hr and again it will get disconnected.
I have checked the signal strength even and it was of no use to do the mess and really worst in choosing this. When I was in city some times, I use to use this while on move and it was really not so useful for any particular urgent calls or any work related to the internet. Need to improve the speed and service.
