About T-Mobile Fiber
T-Mobile Fiber launched in 2025 and offers up to two gigabits of download and upload speeds to more than 500,000 households around the country. While their promise of blazing fast speeds is exciting, we're most interested in their price guarantees and no-contract services. With fee coverage opportunities for those switching to T-Mobile, they're making it pretty easy to switch, too.
If you’ve got any issues with your plan or need help signing up, T-Mobile Fiber is ready to assist you! They offer phone support from 4 AM to 12 AM Pacific Time (next day), seven days a week.
Budget better with T-Mobile price guarantees
When you sign up for T-Mobile Fiber, you’ll get a five-year price guarantee on most plans. That means the rate you get when you sign up is locked in for five years and cannot change during that time. There’s also currently a Founders Club deal on Fiber 2 Gig that locks in your rate for 10 years. According to our research, this guarantee begins as soon as you start or switch to an eligible T-Mobile Fiber plan, so you can be a new or existing customer to qualify.

Frequently asked questions about T-Mobile
Tell your friends and earn a $50 credit
If you’re already a T-Mobile Fiber customer and you love your gigabit internet service, you can refer your friends! When you refer friends, they’ll get a T-Mobile Fiber coupon for $50 off their first purchase. Then, you’ll get your own $50 bill credit that you can put toward your next month of service. You can refer up to 10 people per year, so you could save up to $500 on T-Mobile Fiber with their referral program.
Save every month with Autopay
When you set up Autopay at T-Mobile Fiber, you’ll automatically get a $5 discount on their fiber internet plans. We’ve found this to be one of the easiest ways to save on your internet plan. When we walked through the process ourselves, it only took a few minutes to set up with a debit card, too. If you’ve had trouble remembering to pay your internet bill in the past, this is a pro-level tip to saving and making sure you never forget to pay.
Get up to $750 to cover ISP early termination fees
So, you want to switch to T-Mobile Fiber, but you’re locked into a long-term plan with your current ISP. Normally, this might be the case, but we're happy to see that T-Mobile wants to help you make the move to fiber. With T-Mobile Fiber, you can get up to $750 to cover the cost of early termination fees with your current provider.
Just cancel your current internet plan, switch to T-Mobile Fiber, and send a receipt for your cancellation costs to T-Mobile. They will reimburse you for up to $750 with a prepaid Mastercard. To qualify, you must have been in good standing with your current ISP for 90 days, and you must maintain T-Mobile Fiber service for at least 60 days.
We highly recommend talking with T-Mobile Fiber before taking action on your current plan. That way, you know that T-Mobile Fiber is available to you in your area.

Enjoy summer streaming and savings with blazing fast speeds
When the weather heats up, it’s a good idea to stay indoors during the hottest part of the day! And whether you’re working from home, playing video games, or streaming Netflix, T-Mobile Fiber may be the choice for you. Especially with the current offers they’re running on both Fiber 2 Gig and Fiber Internet.
From a savings perspective, we also like that there’s no annual contract or equipment rental fees on most plans. But, from a daily-life perspective, the promise of 99.99% connectivity and low latency is enticing, too.
