I have been using BSNL card since last 10 years. At the begining the network was not that good. but later on didn’t have any regrets.
Excellent coverage of network. Cheap plans. Good. Even In 3G it is most reasonable.No issues like unwanted msgs. or balance deduction. or activation of unwanted services.
It has been providing many services free of cost for which other companies charge much amount.Now have it has made roaming free.
Was able to use internet in roaming also without any extra charges.
Quite good.
