The mobile operator group Deutsche Telekom and mobile technology company Fortumo have announced the launch of direct carrier billing in Slovakia, according to a press release.

Some 2 million Telekom Slovakia subscribers can now make payments in app stores, games and for digital content by charging the purchases to their mobile phone bill. Slovakia is the second country where the companies have launched a payments partnership, having introduced carrier billing in Czechia last year.

"As a growing proportion of consumers' online time is shifting to smartphones, digital merchants are looking to integrate payment methods that have the best reach and conversion on those devices. Carrier billing helps merchants increase their revenue and we are excited to be working with Telekom Slovakia to help them achieve this," Martin Koppel, CEO and co-founder of Fortumo, said in the release.
