We are excited that you are already a Prime member through Amazon.
In order to take advantage of the Metro™ by T-Mobile offer with Prime, you will need to cancel your current Prime membership and benefits with Amazon by going to your Manage Prime Membership page and selecting “Cancel My Benefits.” On the final confirmation screen, you will see the date that your membership and access to your Prime benefits will end. Once your membership has ended with Amazon, you can re-activate your Prime membership through Metro by being on a qualified rate plan and returning to the registration page here and signing into your current Amazon account.
