T-Mobile is no stranger to promotions, both limited time offers and extended deals, and the Un-carrier has just announced a new one.

If you’re in the market for a new phone, and would rather get one for free, T-Mobile is looking to help you out. The Un-carrier has just announced its “Samsung On Us” promotion, which will see subscribers that sign up for a qualifying rate plan pick up either a Samsung Galaxy On5 or a Samsung Galaxy J7 for free.

The promotion is available for both existing and new customers. To be eligible, you’ll need to sign up for a 6GB of 10GB plan. If you do sign up for the 6GB option, customers will get the Galaxy On5 for free. Signing up for the 10GB plan, though, means customers can choose between the Galaxy On5 or the Galaxy J7. For existing customers, the offer stands, but you’ll need to have T-Mobile’s current pricing to get the free phone.

Signing up means you’ll have to pay taxes on the full price of the device to get started. After that, T-Mobile will charge your bill for the cost of the device, with payments spread out over 24m months. At the same time, T-Mobile will offer you a bill credit for the same amount to cancel out the phone’s monthly charge.

If you switch rate plans to a lower rate, or cancel your subscription altogether, you’ll need to pay off the remainder of the phone’s price tag.

The Samsung Galaxy On Us promotion officially launches on Wednesday, July 13. It’ll be available in T-Mobile stores, authorized retailers, and over-the-phone sales. It’ll be available on the carrier’s website at some point in the future.
