I have been using bank from the time they introduced port, I ported from idea to bsnl
At first it was gud to use a cheaper service when private players were costly, though than also I have to adjust with network problem.
Now a days bsnl has been irritating with there ad during call waiting and busy tone and not only this when ever I recharge my number I receive 9 SMS from bsnl about that recharge which is just useless.
