Wise Recharge works for each operator, we need to create suggestions for each operator like airtel, idea etc.We can’t save user’s usage data on sever, as we have to preserve integrity.

We came up with a generalised plan for each operator. So we can find best plans for user, whether it is STD or local and offnet or onnet.We created best plan algorithm on pattern of the usage where we didn’t need user data, only user’s pattern was sufficient.
