The partnership expands on a previous agreement between the two in Germany, Deutsche Telekom's primary market, to cover the MNO's entire user base in Europe of over 140 million subscribers across 14 different markets.

The agreement establishes Boku as a strategic partner powering Deutsche Telekom's payments offerings, provides the company with an advanced mobile payments API, and gives customers the ability to pay for digital goods and services simply using their existing mobile phone account.

Merchants offering carrier billing-based mobile payments will generate incremental revenue from consumers who find mobile the easiest way to pay, and attract new consumers who previously were unable or unlikely to pay via other payment options, such as credit and debit cards.

When making purchases from their favorite merchants, consumers will benefit from a convenient and secure payment experience that is accessible to Deutsche Telekom subscribers.

"Strategic partnerships with key carrier groups are what will drive the entire mobile payments industry forward," said James Patmore, Managing Director of EMEA for Boku.

"As Boku continues to bring on large merchants with more sophisticated requirements, it requires a deeper level of coordination with the large carrier groups to offer a solution that can deliver across multiple markets and via multiple carriers. This deal is a key milestone in the continuing journey of making mobile payments an established payment system that is accessible to billions of consumers around the world."
