I was using bsnl broadband service from almost 10 months but they was worst in internet service then my friend recommend me to use mtnl broadband service.
I disconnect from bnsl broadband and get mtnl broadband connection.from the first day to till now I never face any connection lost or low speed problem.
They are best even better then BSNL broadband service.The provide nice service support too. I think the connection cost is good according to their service too. the downloading is very fast too.Its good for internet service in my area im totally satisfied with their good service
