However, if you're switching from another carrier, or adding an additional line of service to your account, that discount rises to $300. Once again, you'll need to trade in your old phone to get the sale. > This offer replaces a much better deal to buy one iPhone, get an iPhone XR, or take up to $750 off any "X" iPhone.
