Carrier billing is a payment method that charges a purchase directly to the user's mobile phone bill or deducts it from prepaid credit, with no credit card or bank account involved. The industry name is direct carrier billing (DCB). For consumers it is a convenient way to pay for digital content. For affiliates, it is the engine behind the entire MVAS vertical, and the reason a one-tap subscription in Cairo or Jakarta can convert better than a card checkout in London.
This guide explains how carrier billing works, where it is growing and where it is shrinking, and what it means for anyone sending traffic to mobile subscription offers in 2026. It is written by the media buying team at Mobipium, an affiliate network that has run carrier-billed campaigns since 2013.
What Is Carrier Billing?
Carrier billing is an online mobile payment method where the mobile carrier acts as the payment processor. When a user confirms a purchase, the amount is either added to their monthly mobile phone bill (postpaid) or deducted from their airtime balance (prepaid). The merchant gets paid by the carrier, usually through a billing aggregator, after the carrier takes its share.
Three things make it different from other payment methods:
- No card required. The user's mobile phone number is the payment credential.
- Two steps or fewer. A confirmation message, a PIN by SMS, or a single tap completes the transaction.
- Massive reach. Anyone with a SIM card can pay, including the large share of users in emerging markets who do not own a credit card.
How Direct Carrier Billing (DCB) Works
Behind the user's single tap there is a chain of four parties: the merchant (the digital service), a DCB aggregator, the mobile carrier, and the user. The aggregator holds the technical connections and commercial contracts with each carrier, so a merchant can charge payments across dozens of countries without negotiating with every operator.
A typical direct carrier billing transaction looks like this:
- The user lands on a payment or subscription page on a mobile device.
- The service identifies the user's mobile number, either automatically through the carrier's network or by asking the user to enter it.
- The carrier sends a confirmation message or PIN by SMS, or the user confirms with one tap if the number was already identified.
- The carrier charges the user directly and the transaction is complete.
- Revenue flows from carrier to aggregator to merchant, and in affiliate campaigns, a payout is credited to the affiliate who sent the user.
The three billing flows affiliates actually run
The same DCB infrastructure supports different user experiences. Which one an offer uses depends on the carrier, local regulations and the advertiser. We cover each in depth in Mobile Billing Flows Explained, but here is the short version:
| Flow | How the user confirms | Typical CR | Best fit |
|---|---|---|---|
| Pin-submit | Enters mobile number, then a PIN received by SMS | 4-8% | Europe, regulated GEOs, Wi-Fi traffic, beginners |
| One-click (click flow) | One tap, number identified by the carrier on mobile data | 8-15% | MENA, parts of Asia and Africa, mobile data traffic |
| MO flow | Sends a keyword by SMS to a short code | Varies, declining | Legacy markets, specific carriers |
Conversion rates are click-to-subscription ranges observed across Mobipium campaigns. They move a lot by GEO, carrier and traffic source.
What Can You Buy With Carrier Billing?
Carrier billing is built for digital goods and digital services, not physical goods. The main categories are:
- Mobile games and in-app purchases. DCB is ideal for microtransactions in mobile gaming, and gaming is the largest single segment. Mordor Intelligence estimates gaming accounted for about 41% of DCB revenue in 2025.
- Subscriptions to digital content. Video and music streaming, quizzes, education, wellness and utility apps.
- App store purchases. Google Play and other app stores accept carrier billing with many carriers worldwide.
- Charitable donations and micro-payments in some countries.
Mobile Value-Added Services (MVAS) sit right inside the subscription category. A user subscribes to a content portal with a daily, weekly or monthly charge, and the subscription is billed by the carrier. That recurring revenue is what lets advertisers pay affiliates a CPA on every new subscriber.
A Short History of Carrier Billing
Charging content to a phone bill is older than smartphones. Premium rate numbers billed callers for services from the 1980s. NTT DoCoMo launched billing for mobile content through i-mode in Japan in 1999, and WAP billing appeared around the same time. In the early 2000s premium SMS made ringtones and wallpapers the first mass-market mobile content, and operators such as Vodafone expanded carrier billing across digital content. App stores then plugged into the same rails, and today direct carrier billing covers games, streaming, apps and subscriptions in most countries.
Pros and Cons of Carrier Billing
| Pros | Cons |
|---|---|
| No credit card or bank account needed | Limited to digital goods and small amounts |
| Checkout in one or two taps | Carriers often cap daily or monthly spending |
| Card details are never shared with the merchant | Refunds and disputes can involve the carrier, aggregator and merchant |
| All purchases consolidated on the mobile phone bill | Easy purchases can lead to unmonitored spending |
| Works for unbanked and underbanked users | Higher fees for the merchant than cards |
Payment providers report very high checkout conversion for DCB. Digital Virgo, for example, cites a 77% conversion rate on the carrier billing payment page versus about 10% for credit card. Keep in mind that this measures users who already reached the payment step. For affiliates, the relevant metric is click-to-subscription, which is the 4-15% range in the flow table above.
Is Carrier Billing Still Possible in 2026?
Yes, but the answer depends heavily on the region, and this is where most generic guides get it wrong.
In the United States, carrier billing for app stores has been shrinking for years. Verizon was removed from Google Play subscription billing in 2022, and other major US carriers have followed. If you are a US consumer, your carrier may no longer support it.
In emerging markets the opposite is true. Across Africa, the Middle East, Southeast Asia and Latin America, carrier billing remains one of the most popular payment methods for digital content because card penetration is low and prepaid airtime is universal. Mordor Intelligence sizes the global direct carrier billing market at roughly USD 53 billion in 2026, growing at around 13% a year through 2031.
For affiliates, that split is the whole point. The volume, and the margin, sits in markets where carrier billing is the default and card checkouts barely convert.
Carrier Billing vs Other Payment Methods
| Factor | Carrier billing | Credit card | Digital wallet |
|---|---|---|---|
| Requirement | Mobile phone number | Card and bank account | Wallet account, often linked to a card |
| Checkout steps | 1-2 | 4-6 fields plus bank verification | 2-3 |
| Reach in emerging markets | Very high | Low | Medium, growing |
| Merchant cost | High, carriers and aggregators keep a large share | Low | Low to medium |
| Best for | Low-ticket digital content and subscriptions | Any purchase, including physical goods | Repeat online purchases |
The higher cost for the merchant is the trade-off for conversion. Carriers keep a significant share of each transaction, which is why carrier-billed services are priced low and why payouts vary so much from one carrier to another.
Why Carrier Billing Matters for Affiliates
If you run mobile traffic, carrier billing changes the economics in three ways.
Friction collapses. No card form means no abandoned checkouts. A user on a push or in-app placement can go from click to subscription in under ten seconds.
The audience widens. Tier 3 GEOs like Egypt, Nigeria, Indonesia and Pakistan become monetizable because the payment method works for everyone with a SIM card. That is why payouts in those markets are low per conversion but strong on net margin. Our MVAS payouts by GEO breakdown shows the real ranges, from $0.25 in Tier 3 to $15 in Tier 1.
Compliance becomes part of the job. Local regulations decide which flows are allowed, what the landing page must disclose and how the confirmation message is worded. A campaign that ignores them gets paused, and the carrier can block the service across the whole country. A network that tests offers with its own media buying team, as Mobipium does, filters out a lot of that risk before an affiliate spends a dollar.
How to Start Promoting Carrier-Billed Offers
- Pick one GEO and one flow. Pin-submit in a single country is the safest first test.
- Match traffic to the flow. One-click needs mobile data users. Push and native traffic carries a lot of Wi-Fi users, so pin-submit fits better.
- Use the network's tested pre-landers. On Mobipium, pre-landers tested by the internal media buying team are available in the campaign setup.
- Read the stage report, not only conversions. Blocked clicks by targeting, cap or time frame tell you why a campaign is not converting before you blame the offer.
- Keep the flow clean. Hidden prices and fake buttons convert for a day and then get the service blocked. See affiliate fraud in mobile and MVAS.
- Budget for the learning phase. See our guide on the minimum budget to start MVAS.
Frequently Asked Questions
What does carrier billing mean?
It means the cost of a purchase is charged directly to your mobile phone carrier account, either on your monthly mobile phone bill or deducted from prepaid credit, instead of a card or bank account.
What does DCB stand for?
DCB stands for direct carrier billing. It refers to the same payment method, where the carrier bills the user directly for digital content or services.
Is carrier billing a secure payment method?
Yes. The user never shares card details, and every transaction is tied to the SIM and confirmed by the carrier, usually through a PIN or confirmation message. Most disputes come from unclear subscription terms, not from stolen payment data, which is why regulators focus on landing page disclosure.
What is a mobile payment on my bank statement?
Carrier billing charges do not appear on bank statements. They appear on your mobile phone bill or as a reduction of prepaid credit. A "mobile payment" line on a bank statement usually refers to a digital wallet such as Apple Pay or Google Pay.
Can I use carrier billing for physical goods?
Generally no. Carrier billing is designed for digital content and services. Some markets allow small physical purchases, but it is the exception.
