If you're an Optus prepaid customer, there's no reason to download your Spotify playlists to your phone any more. New and existing prepaid customers on Australia's second largest mobile network will have uncapped, quota-free streaming of half a dozen different music services including Spotify and Google Play Music.
Optus Music, as the telco calls it, kicks in on May 2 on My Prepaid Ultimate, My Prepaid Daily Plus and "other selected plans", and will let Optus customers access music from the extensive catalogues of Spotify, Google Play Music, Guvera, iHeartRadio and Pandora without that usage impacting their existing data allocations.
As long as customers have some data or prepaid credit applied to their accounts, they'll be able to access these music streaming services -- through their existing subscriptions, except in the free tiers of Spotify -- without data use being counted as usage.
Apple Music is an obvious omission from the otherwise strong list -- it's likely that Apple's ongoing partnership with Telstra played a role in this decision. Optus has around 3.7 million prepaid network customers, nearly equalling Telstra's 3.8 million and eclipsing Vodafone's 1.7 million. [Optus]
