More Cyber Monday deals at T-Mobile
Is Cyber Monday the best time to buy a new phone?
While phone deals are pretty common throughout the year, the offers typically get an upgrade around the holiday shopping season. That includes bargains like enhanced trade-in credit, new line discounts and bundle offers for those who need multiple new phones, which are all available now at T-Mobile.
Do T-Mobile Cyber Monday deals require a contract?
Yes, just about any discount or deal being offered at T-Mobile (or any other major carrier) will require you to activate your device on a plan with a long-term contract. The savings are usually then distributed as bill credits each month. Though it’s worth noting that T-Mobile’s contract periods are only 24 months, compared to a 36-month Verizon or AT&T contract.
