Direct Carrier Billing (DCB) is a mobile payment method that allows users to make purchases by charging the cost directly to their phone account.

It offers a convenient and secure way for consumers to pay for digital goods, services, and even physical products, without needing to use a credit card, debit card, or bank account.

1. Choose a Service or Product: Visit a website, app store, or platform where you want to make a purchase. Examples include Google Play, Apple App Store, streaming services, or digital marketplaces.

2. Select Direct Carrier Billing as the Payment Method: At the checkout or payment screen, look for "Carrier Billing," "Mobile Billing," or a similar option. If it's your first time, you may need to set up DCB in your account settings (e.g., on Google Play: Payment Methods > Add Payment Method > Use Mobile Billing).

Selection of Payment Method: Users select "Direct Carrier Billing" when making a purchase online.

Authentication: The system identifies the user via their mobile number, either through the mobile network or by manual entry.

Verification: A one-time password (OTP) or PIN may be sent to the user's mobile phone to confirm the transaction.

Billing: The amount is added to the user’s postpaid phone bill or deducted from their prepaid balance.

DCB can be used for a wide range of digital and some physical goods and services:

• Purchasing apps and games on Google Play or Apple App Store
• Paying for streaming services like Netflix and Spotify
• Donating to charities through mobile campaigns
• Buying tickets, public transport passes, or small physical items

• Asia
• Western & Eastern Europe
• Middle East & Africa
• Latin America

The main DCB providers globally include:
