.. Hi ,
I have an unused BSNL sim with me. Now I want to use it. It has 5 months of validity . I want to know what are the option to recharge it online to get full recharge because online recharge I tried is not giving full talktime. Since there is no one around me using bsnl , I have no idea of full talk time recharges.

In BSNL , generally full talk time is available on Rs. 100 or more top-up.
You can send SMS "Help" to 52244 and you will receive all existing offer details from BSNL.
