as i explained my earlier post along with number of advaNtages, disadvantages also there.
1.it based on signal strength of your area
2.at present limited type of plans available
3.LOGIN SYSTEM, yes you need to login before starting browseing – yak – i don;t like this. while shutdwon you need to log off other wise you account will be locked off at server side and you need to call customer care to reset !!! this is only major disadvatages.
otherwise speed is excellent and connection is very stable.
