Wouldn’t it be nice to have one of your monthly expenses remain stable for a while? Phone plans have seemed tumultuous recently, which is why T-Mobile’s five-year price guarantee with new Experience plans was such a surprise when it was announced earlier this year. With costs increasing on everything, and knowing that phone plans often come with strings attached, we’ve looked into the details of this deal so you can start saving on your next phone plan.

T-Mobile’s price guarantee applies to the Experience plans but not the Essentials plans. The first tier is Experience More, which starts at $90 per month for a single line and includes Unlimited Premium data and text. It also offers 60GB of high-speed hotspot data (then unlimited at 3G speeds), Apple TV Plus, Netflix (with ads), Hulu (with ads) and is upgrade-ready every two years. If you need three lines, you’ll get the third one free. This plan includes five-year price protection and is $5 less when you sign up with AutoPay.

Hey, did you know? CNET Deals texts are free, easy and save you money.

Experience Beyond is the next tier, which starts at $105 per month and offers unlimited talk and text, plus 250GB of high-speed hotspot data (then unlimited at 3G speeds). Every streaming service listed above is included, as well as smartwatch and tablet lines starting at $5 per month. Beginning in July, Experience Beyond customers will get T-Satellite service included in the plan. (Experience More customers can get T-Satellite free through the end of 2025, then pay $10 per month as an add-on.) Other perks include upgrade eligibility every year and 30GB of high-speed data in Mexico and Canada. T-Mobile will knock off an extra $5 per month when you sign up for AutoPay, which means you’ll pay just $100.

Families can sign up for two lines and get the third line free, which can save them up to 20% when switching from other carriers. A quick reminder that the five-year price guarantee applies only to the Experience plans and doesn’t apply to other T-Mobile plans.

Why this deal matters

T-Mobile’s five-year price guarantee is a great way to have a consistent phone bill that can also save you on data fees and subscriptions. Both eligible Experience plans are an additional $5 off when you sign up for AutoPay. With so many price increases on other basics, this is a great deal for anyone who wants to save on a recurring monthly expense.
