How does the Premium free trial work?
By Dan Taylor
The monthly plan advertises a one-month trial when Apple confirms your account is eligible.
The monthly Premium option includes a one-month free trial for eligible Apple IDs. Apple decides eligibility and shows the exact offer, price, and renewal date before you confirm.
Unless cancelled before the trial ends according to Apple's displayed terms, the subscription automatically renews at the shown monthly price. You can always continue with the free version instead of starting a trial.
