Apple Music Promo

[Doc_Holiday]

I recently switched from the New Verizon Unlimited plan to the Beyond Unlimited, which went into affect on 2/22. Last month I took advantage of the 6 free months of Apple Music before I changed plans. On my account it still shows the trial, with an expiration date of 7/16/19. My question is, since Apple Music is included with my new plan, once the trial period ends on 7/16, will the subscription automatically change over to the free subscription or do I need to make changes in my add-ons for it to take affect? TIA.
