If you’re looking to activate your existing smartphone on a new carrier, T-Mobile can be a great choice thanks to its aggressively priced plans, weekly perks and freebies, as well as frequent free line deals, not to mention all those impressive ongoing network upgrade efforts.

Whether you want to bring your own phone to Metro or get a new one from T-Mo’s “flagship prepaid brand”, you can score the aforementioned gift after maintaining your account in good standing for at least 75 days and paying for three consecutive months of service. Once that requirement is met, you’ll receive a text message containing instructions on how to claim your $100 virtual prepaid card, which will need to be done within another 30 days.

Keep in mind that this is an online-only promotion, so you’ll have to use the official Metro by T-Mobile website to buy a SIM kit and perform the actual activation of your new or existing device.
