T-Mobile Fiber is here — and it is the retail payoff of a multi-year buying spree. After spending billions to fold Lumos and Metronet into fiber joint ventures, T-Mobile is now selling T-Mobile Fiber directly to homes, with a 5-year price guarantee, unlimited data, free equipment, free installation, and no annual contract. If your income runs on a home connection, that combination is worth a hard look.

Here is every current T-Mobile Fiber plan, the real prices showing on T-Mobile today, and an honest read on whether it beats what you already pay — especially for upload-heavy work like video calls and large file transfers. (For the full deal history behind this launch, see our guide to T-Mobile’s fiber and spectrum acquisitions.)

The 30-second version
What it is: 100% fiber home internet from T-Mobile, the retail face of its Lumos + Metronet fiber joint ventures
Plans: Fiber 300 Mbps, Fiber 1 Gig, Fiber 2 Gig — speeds vary by location
Real prices (with AutoPay): $45 / $60 / $70 a month, plus taxes & fees
Guarantee: 5-year price lock on the internet rate while on an eligible plan
No fluff: Unlimited data, Wi-Fi router and installation included, no annual contract

T-Mobile Fiber plans and prices for 2026

There are three T-Mobile Fiber speed tiers, and the prices below are the AutoPay rates showing on T-Mobile’s site right now. The AutoPay discount is worth $10/month — without it (or paying by something other than a bank account or debit card), each plan runs $10 more. Speed tiers and availability vary by address, so always confirm at your own.

Fiber 300 Mbps — for everyday remote work

$45/month with AutoPay ($55 standard), plus taxes and fees. Symmetrical speeds for everyday remote work — reliable video calls, file syncing, and streaming for a typical household.

Fiber 1 Gig — for busy multi-person homes

$60/month with AutoPay ($70 standard), plus taxes and fees. Everything in the 300 tier, plus a mesh Wi-Fi extender as needed to cover a larger home. T-Mobile is currently running a “Month on Us” promo on this tier. This is the sweet spot for several people streaming, gaming, and on calls at once.

Fiber 2 Gig — for power users and creators

$70/month with AutoPay ($80 standard), plus taxes and fees. T-Mobile’s fastest tier, with the strongest Wi-Fi, for smart homes, creators, and heavy uploaders. At launch it carries a “Month on Us” plus a $100 prepaid-card promo on qualifying activations — limited-time, so read the current terms before counting on it.

Watch the AutoPay and promo fine print

Two things to keep straight: the headline prices assume Fiber AutoPay (otherwise add $10/month), and the launch promos — Month on Us, $100 back, refer-a-friend — are limited-time and change. The 5-year price guarantee covers the internet data rate itself, not taxes, fees, equipment upgrades, or promotional pricing.

T-Mobile Fiber 2026 plans at a glance
Fiber 300 Mbps: $45/mo with AutoPay — everyday remote work, symmetrical speed
Fiber 1 Gig: $60/mo with AutoPay ($70 standard) — busy households, adds mesh Wi-Fi
Fiber 2 Gig: $70/mo with AutoPay ($80 standard) — power users and creators
All plans: unlimited data, router + install included, no annual contract, 5-year price guarantee

Why the price guarantee matters if you work from home

The reason most home-internet bills creep up is the post-promo reset: you sign at a great rate, and a year later the price jumps. T-Mobile’s 5-year price guarantee locks the internet data rate while you stay on an eligible plan, so that predictability is arguably worth as much as the speed itself.

It is also worth knowing where this network came from. T-Mobile built Fiber by buying its way in — through 50/50 joint ventures that absorbed Lumos (with EQT) and Metronet (with KKR) — and it expects to reach 12 to 15 million fiber households by 2030. That is why availability is patchy today but expanding fast, and why the brand you sign up with is now T-Mobile rather than the company that built the line in your neighborhood.

In our provider mapping, T-Mobile Fiber currently registers in under 0.3% of tracked ZIP codes — but that footprint is expanding faster than any other brand on the list. Through its Metronet (~2.6M passes) and Lumos (~320K) acquisitions, T-Mobile is targeting 12–15 million homes passed by 2030, which would represent roughly 10% of U.S. households. At that scale T-Mobile Fiber would leapfrog most regional cable brands and land in the same tier as Frontier- and Ziply-scale fiber overbuilders.

T-Mobile Fiber vs. T-Mobile 5G Home Internet

If you already considered T-Mobile, you have probably seen its 5G Home Internet — the fixed-wireless service nearly 7 million customers already use. The new Fiber product is different in ways that matter for remote work:

• Speed ceiling: Fiber offers symmetrical speeds up to 2 Gig; fixed-wireless 5G is typically slower on the upload side, which is the side video calls and file uploads lean on.
• Consistency: Fiber is a wired line, so it does not share the same congestion and signal variability that wireless can see at peak hours.
• Availability: 5G Home Internet reaches far more addresses today; Fiber is rolling out market by market. Check both at your address before deciding.

Rule of thumb: if T-Mobile Fiber is live at your address and upload-heavy work is your reality, Fiber is the stronger pick. If it is not there yet, 5G Home Internet or satellite is the fallback worth comparing — and if you are weighing Starlink, see Starlink Price Increase 2026: What It Means.

Pairing your internet with the rest of your home setup

Switching providers is the natural moment to look at the rest of your monthly home bills, not just the internet line. Two quick wins while you are at it:

• Electricity: If you live in a deregulated state — Texas, Pennsylvania, Ohio, Illinois and much of the Northeast — you can shop your electricity supply the same way you shop internet, and lock a fixed rate before summer peak.
• Home security: A faster, more reliable connection also makes smart-home security (cameras, sensors, professional monitoring) work better — worth bundling into the same decision.

Comparing all three in one place is exactly what a utility marketplace is for — one address, one set of choices.

Does T-Mobile Fiber have a contract or data cap?
