Perfect win win for them. They don't have to disconnect unused numbers having balance, hence keeping subscriber numbers up. At the same time, they get to earn too 😀

EDIT

Its within the framework of the rules, so to speak.

Mobile numbers having balance of Rs 20 cannot be deactivated - timesofindia-economictimes

Best way to avoid this is keep recharging 10rs every month.

It is better to pay Rs 20 than loose your unused no in most cases , this rule was brought for the benefit of the customers .
