If you're open to other phones, also check out Cyber Monday deals on the iPhone XS, XR and iPhone X, Galaxy S9 and Note 9, and Pixel 3 and 3 XL. And remember that more holiday offers are around the corner during the gift-giving season. We just won't know exactly what they'll be until they're upon us.

If you already have one or more phone lines through T-Mobile and add another and trade in an old phone, the carrier will give you a new OnePlus 6T phone to use for the additional line. This is one of our favorite phones for 2018 for its excellent performance for the price. A price of "free" is even better.
