T-Mobile is offering eligible customers 12 months of DoorDash DashPass for free through its T-Life app as part of its Member Month promotion. DashPass normally costs about $9.99 per month and includes $0 delivery fees on eligible orders, reduced service fees, and exclusive member discounts. Customers must redeem the offer within the promotional window, and after the free year ends, the subscription automatically renews at the standard monthly rate unless canceled.
