Verizon's got two new promotions kicking off tomorrow: one for Android users and one for iOS users.

First up, Verizon is launching a Buy One, Get One deal on the Samsung Galaxy S9. Customers who buy a Galaxy S9 or S9+ on a device payment plan can get a second Galaxy S9 for free in the form of $799.99 in bill credits spread out over 24 months.

To get this deal, you'll need to activate at least one new line of service. No trade-in is necessary.

Verizon is also launching a deal tomorrow that'll offer up to 50 percent off an iPhone 8, iPhone 8 Plus, or iPhone X with qualifying trade-in. To get this deal, you'll need to purchase your new iPhone on a device payment plan, sign up for an unlimited data plan, and trade in an eligible phone.

This deal is available to upgrading customers and switchers. Also worth noting is that your discount will be applied over 24 months.
