T-Mobile has announced a new agreement with music streaming group Deezer in the Netherlands.
A co-branded service will launch in June and will be supported by local labels, the telecoms firm said.
T-Mobile and Deezer hope that they can directly develop high quality paid-for services for customers in the country, rather than a free service.
As of next month, T-Mobile customers will be able to access 'T-Mobile & Deezer Music' as part of a bundle along with T-Mobile tariff plans at lower prices.
They will also be able to access the product as a standalone option.
Head of Benelux at Deezer, Johan Van Roy, said: "The Dutch market is very important for Deezer. Together with our partner T-Mobile we will offer music fans instant web-based access to the biggest music library on the device of their choice."
Consumer marketing director at T-Mobile Netherlands, Raymond Perrenet, added: "With Deezer, we offer great value to our customers and bring the open internet closer."
