The problem

Your users are rural, often offline, and almost never banked - but they all top up their phone.

With Digimart

A ৳10/month advisory subscription billed to mobile balance reaches people no card network can.

Unlock a Premium Feature

Reaching Users No Card Network Reaches

Rural users are often offline for long stretches and rarely hold a bank account, yet almost all of them top up a mobile phone regularly. A premium feature gated behind a card payment simply never reaches this group, no matter how useful the feature is.

The unlock typically happens like this:

The user taps to unlock the premium feature or advisory tier Digimart sends an OTP for the ৳10 monthly charge Confirmation activates the feature immediately The subscription renews each month against the same mobile balance

Why Small Recurring Charges Work Here

A ৳10 per month price point only makes sense if the payment method matches how the user already manages money. A few things make this combination work:

No card or bank account is required at any point in the flow The price point matches everyday mobile recharge amounts users are used to Renewal happens automatically, so the feature does not silently deactivate The same rail reaches users whether they are online constantly or only occasionally

It is worth adding that this works best for advisory or utility features with clear, ongoing value, since a one time upgrade fits the One Time Charging SDK better.

The users hardest to reach with a card are often the users who most need the product.

Where This Fits Into Your Product

The Subscription Charging SDK sits behind whatever gate currently blocks the premium feature. Utility and productivity apps generally place it directly on the existing "Upgrade" or "Unlock" control, so the feature itself does not need to change, only what happens when a user taps to access it.
