Reverse Billed Data

Your customers reach you
data-free.

Sponsor the data. When someone opens your app, portal or USSD service, the bytes are billed to you — not to them. A flat data balance never stands between your business and the person trying to use it.

How it works

You nominate the destination. We make it free to reach.

Black Mobile coordinates directly with each MNO to zero-rate the traffic bound for your service. The subscriber's data allowance is never touched — the session is charged to your account instead.

Allowlisting

Whitelist your domains and endpoints.

Name the hosts, APIs and shortcodes that should be free; only that traffic is sponsored.

Coverage

Sponsored across every MNO we bind.

One agreement with Black Mobile; we handle the per-network zero-rating on your behalf.

Budgets

Caps, budgets and per-app limits.

Set a monthly data budget; throttle or stop sponsoring the moment it's reached.

Analytics

See exactly what you sponsor.

Megabytes by app, by campaign, by network — reconciled against MNO usage records.

Integrity

Only your traffic, nothing else.

Strict allowlisting and abuse controls so sponsored data can't be tunnelled or siphoned.

01Banking & fintech

Let every customer bank, even at zero balance.

The moment a wallet or banking app is unreachable because the customer ran out of data is the moment they churn. Sponsor the app so balances, transfers and support are always one tap away.

  • App, API and support portal all zero-rated
  • Works on the cheapest Android handset and on USSD fallback
  • Data budget capped per month — no runaway spend

02Government & health

Essential services, never gated by data.

Public health information, grant applications, exam results, emergency lines — the services people need most are the ones they can least afford to load. Sponsor them so access never depends on a data bundle.

  • Health, education and civic portals reachable free
  • Zero-rated on feature phones via USSD and SMS
  • Per-service reporting for donor and grant accountability

03Onboarding & growth

Sponsor the first session, win the customer.

Acquisition dies at the sign-up screen when a new user has no data. Zero-rate onboarding — the download, the OTP, the KYC upload — and remove the single biggest reason people never finish.

  • Free from the app store link through first successful login
  • OTP delivery and document upload included in the sponsored path
  • Convert the sponsored session into a measured acquisition cost
