TeliaSonera is to launch an "all you can eat" mobile music download service.
The Swedish operator becomes the latest mobile player to offer subscribers unlimited access to "millions of songs" from all the major record labels plus several independent labels.
The operator said that Telia Musik can be downloaded to either a mobile or a PC.
Telia in Sweden will be the first mobile operator to launch the service, which will be free for the first three months and cost SEK99 (USD $12.2) per month thereafter.
However, TeliaSonera said the service will eventually be offered to more than 13.3 million mobile customers across six of its markets, including Norway, Finland, Denmark, Estonia and Lithuania.
In Sweden, Telia Musik will compete with Sony Ericsson’s new unlimited music download service, PlayNow Plus.
It is being offered by rival mobile operator, Telenor Sweden, and also costs SEK99 per month.
The service could also compete with Nokia’s high-profile Comes With Music product, which is being offered in the UK by mobile operator 3 UK and is expected to launch in further markets soon.
