What is Direct Carrier Billing?

Direct carrier billing (DCB) routes payment requests through the user's mobile network operator (MNO). When a user selects a subscription or one-time purchase, the app sends a billing request to the carrier's system. The carrier verifies the user's identity, usually via a one-time password (OTP) sent to their phone. Once approved, the amount is added to the user's monthly bill or deducted from their prepaid airtime balance.

For operators, this process bypasses traditional payment gateways. You do not handle card data or manage refunds through a third-party processor. Instead, the carrier manages the transaction lifecycle. You receive a consolidated payout from the carrier or an aggregator after a settlement period, typically 30 to 90 days. This model relies on the trust users place in their mobile service provider. It works best when the user's mobile number is linked to their streaming account. If the number changes or the account is prepaid with insufficient balance, the transaction fails. Operators must handle these edge cases in their user flow to avoid confusion.

In many emerging markets, credit card ownership is low. A significant portion of the population relies on mobile phones for internet access and payments. DCB taps into this existing behavior. Users already pay their phone bills; adding a streaming subscription to that bill is a small step. This lowers the barrier to entry for new subscribers. It also reduces cart abandonment at checkout. Users who might hesitate to enter card details are more likely to complete a purchase if they only need to confirm an OTP.

However, DCB is not a universal solution. It is region-specific. A carrier in one country may not support DCB for all content types. You must evaluate the market potential before integrating. The revenue share with carriers can be significant, often higher than standard payment gateway fees. This impacts your net revenue per user. Operators must model this cost against the higher conversion rates. DCB is a strategic tool for market penetration, not just a payment method.

Both methods allow users to pay without entering card details, but the mechanics differ. IAP routes payments through the app store (Apple or Google). The app store handles the transaction and takes a commission. DCB routes payments through the mobile carrier. The carrier handles the transaction and takes a fee. IAP is available globally wherever the app store operates. DCB is limited to regions and carriers that support it. IAP offers faster settlement, usually within weeks. DCB settlement is slower, often monthly or quarterly. IAP requires users to have an active app store account. DCB requires a valid mobile number.

Operators often overlook the settlement lag. Cash flow planning must account for the delay between user payment and carrier payout. Another error is assuming DCB works everywhere. It is not a global standard. You must verify carrier support in your target markets. Some carriers only support DCB for specific content categories or price points. Failing to check these limits leads to failed transactions. Operators also neglect the user experience for failed payments. If a user's prepaid balance is too low, the transaction fails. Your app must clearly communicate this and offer alternative payment methods. Finally, relying solely on DCB limits your audience. Users without mobile phones or in areas with poor carrier support cannot use it. Use DCB as one option in a multi-payment strategy.
