If you are a current Sprint subscriber, or if you are planning to start new Sprint service, Sprint launched a brand new promotion, you get SIX FREE Months of TIDAL HIFI music streaming service. That’s the full high resolution service $20 per month subscription, FREE for six months.

New Sprint customers have 90 days (from starting Sprint service) to begin their free six month Tidal trial. Existing Sprint customers can sign up for it using the links at the above page. There are FAQs at the aforelinked page covering most of the questions.

AFTER the SIX MONTH FREE TRIAL ENDS

After the six months are over, AND if you don’t cancel beforehand, you will be automatically converted to the $10 per month Premium subscription. If you decide you like the HIFI service, you have to manually upgrade from Premium to HIFI. If you don’t like it and forgot to cancel beforehand, you can cancel at any time in the future. I’m assuming you won’t get a partial refund for the month in progress (but I could be wrong).
