Starting June 9, Sprint customers can visit Sprint.com (or a brick-and-mortar Sprint location) for information on how to add Tidal HiFi to their plans. Tidal HiFi plans include on-demand access to more than 48.5 million music tracks, 175,000 videos, and exclusive content from artists like Calvin Harris, Nicki Minaj, and Beyonce. That’s in addition to curated playlists, live-streams, music videos, ticket giveaways,

Once the six-month Tidal trial ends, subscriptions go up to $10 per month for Tidal Premium.

To mark the promotion’s launch, Tidal and Sprint are teaming up to fund a charitable project aimed at children who lack internet at home. The 1Million Project, which seeks to connect 1 million low-income high-school students who lack access to an affordable internet subscription, will provide free mobile devices and up to four years of free high-speed wireless connectivity for high school kids who qualify.

Starting June 9, Sprint will donate $2 for every new line action — up to $1 million total — with a device purchase or lease to support the 1Million Project.

“Education is key to a bright future, and unfortunately not everyone has access to the tools and resources needed to succeed, including internet access and mobile devices,” Tidal artist-owner, Nicki Minaj, said. “I’m so proud to work with Sprint and Tidal, who are prioritizing programs like the 1Million Project in order to ensure that a student’s zip code and family financial situation aren’t roadblocks to a successful future.”

The Tidal deal dovetails with Sprint’s discounted rate plan. For a limited time, the carrier’s covering any cancellation fees new customers incur up to $650 per line, in the form of a prepaid reward card. For a limited time, Sprint is offering four lines of unlimited data, talk, and text for $22.50.
