A basic question: what exactly is a mobile balance. I got a pre-paid mobile connection recently. I paid Rs:87 to extend my validity (BSNL APOORVA scheme) it was expiring in 8/11/2016 but it's been extended till 2017. However the amount did not credit to my balance.

I called up BSNL support - the lady told me that the amount I paid won't credit to my balance? I googled 'validity' and apparently:
1. What I did by paying Rs:87 was a recharge.
2. AMOGH has a validity of 180 days - 6 months.
3.02/5/2017 expiry, balance 278.3864
What exactly is a mobile balance? What is validity? I'm new to this - please help.
