Motorola will give you up to $300 for your old phone after you purchase the Moto X or Moto G
When you are seeking a quote from Motorola, you will be asked some questions about your trade. Is the device still working? Is there any liquid damage? Is the screen broken? A 16GB Apple iPhone 5s in good working condition will fetch $240. A BlackBerry Z10 from Verizon or Sprint will bring you $60.
The next step is to purchase the Moto X or Moto G. You then have 30 days to send in your trade. After that, you will receive your pre-paid Visa card in the mail. The deal is good only for devices purchased from the Moto Maker site. The first step is to see what Motorola will offer you for your phone, and proceed from there.
