T-Mobile markets its price lock as a single promise, but there are actually two completely different versions of it — and they work very differently. Home internet customers get a genuine rate freeze on their service price for five years. Phone plan customers get something narrower: if T-Mobile raises rates and you decide to leave, they’ll cover one month’s bill. Knowing which version you have changes how much protection you actually hold.
What T-Mobile’s Price Lock Actually Means — Nine Plain Answers
These are the questions customers search after signing up, usually when something on their bill doesn’t match what they expected. Each one has a direct answer based on T-Mobile’s own published terms.
It covers the base rate plan price — the advertised monthly rate for your service. It does not cover taxes, government fees, per-use charges, optional add-ons, third-party services like streaming subscriptions, or equipment fees. T-Mobile’s published FAQs state explicitly: “taxes and fees are outside of Price Lock.” Your base service price is frozen; the rest of your bill can still move. This is meaningfully different from a full-bill freeze — and it’s important to understand before assuming your total monthly cost is guaranteed to stay flat.
Yes — and most people don’t know this. Home internet customers who activated a Rely, Amplified, All-In, or AWAY plan after December 11, 2024 have the 5G Internet Price Lock: a genuine 5-year rate freeze on the fixed-wireless internet service price, with no recourse payment if rates rise. Phone plan customers on Experience plans activated after April 23, 2025 have the 5-Year Price Guarantee: a freeze on the wireless plan’s base rate for 5 years. There was previously a third version — the “Last Month Price Lock” for accounts activated January 18–April 22, 2025 — that only refunded your final month’s bill if T-Mobile raised rates and you left. Know which version is attached to your account by checking your sign-up date and plan.
Yes, if you activated after December 11, 2024 on a Rely, Amplified, All-In, or AWAY plan. The rate you signed up at stays frozen for five years. T-Mobile confirmed in its FAQ that this also covers accounts that transitioned to a qualifying plan in 2026. The protection applies to the fixed-wireless internet service price — the Rely, Amplified, or All-In rate you see on the bill. It excludes taxes, fees, the AutoPay discount (which can change if you stop using AutoPay), voluntary equipment upgrades, and add-ons. No contract is required, and there’s no early termination fee if you decide to leave during the 5-year window.
The 2026 price increase affected customers on legacy plans — Magenta, T-Mobile ONE, Simple Choice, and certain older grandfathered Sprint plans — most of which were built in the 3G and 4G eras before the current price lock framework existed. Those customers were moved to modern Experience plans, with some seeing increases of up to $6 per voice line. Customers already on qualifying plans with an active price lock were not covered under the old guarantee language in many cases. This is why the activation date matters so much: the 5-Year Price Guarantee on Experience plans activated after April 23, 2025 is a forward-looking protection. The lesson is to confirm your specific plan version and its associated guarantee in writing.
For phone plans: T-Mobile’s FAQ specifies the price lock applies to the published rate on the date of activation for each line, not the date the account was opened. Adding a new line starts a fresh 5-year clock for that line, not for your entire account. For home internet: the lock is account-level and does not reset when you request a gateway upgrade or change your billing address within the coverage area. What can disrupt home internet coverage: voluntarily upgrading to a different speed tier or plan, or switching to a plan that doesn’t carry the 5G Internet Price Lock designation.
This catches a lot of people. The advertised home internet prices — Rely at $50/mo, Amplified at $60/mo, All-In at $70/mo — already factor in a $5 AutoPay discount. If you cancel AutoPay, your bill rises by $5/mo even within the price lock period, because the AutoPay discount is explicitly listed as an exclusion from the lock. The base plan price stays frozen; the discount tied to AutoPay does not. Similarly, if you have a T-Mobile voice line bundle reducing your internet rate by $15/mo, canceling that phone line removes the credit and effectively raises your internet bill — again, without violating the lock, because bundle credits are not the locked rate.
T-Mobile has not pre-committed to any rate after the 5-year window closes. The guarantee is for 60 months from activation; after that, standard pricing practices apply, which means T-Mobile can adjust your rate with notice. The practical move: treat month 54 or 55 as your decision point. At that time, evaluate whatever the current T-Mobile plans, competitors, and your usage needs look like — and either negotiate, switch plans, or move providers from a position of choice rather than reacting to a surprise increase. The expiration isn’t automatic chaos, but it does remove the contractual protection you’ve been relying on.
Yes — and it’s the strongest price commitment in T-Mobile’s lineup. T-Mobile Fiber launched officially in June 2025 with a 5-year price guarantee on all plans. The Founders Club limited-time offer on the 2 Gig plan at $70/mo with AutoPay carried a remarkable 10-year price guarantee. T-Mobile Fiber is currently available to over 500,000 households following T-Mobile’s acquisition of Lumos, with coverage expanding across select U.S. markets. Fiber plans include unlimited data, symmetrical upload and download speeds, no monthly equipment fees, no installation charges, and no annual contracts. If fiber is available at your address, it represents T-Mobile’s most competitive long-term pricing commitment.
It’s genuinely competitive — with important caveats. Xfinity also offers a 5-year price lock on internet, but it applies to the base rate and excludes taxes and fees the same way T-Mobile’s does. Verizon Fios’s price lock applies for 2 to 5 years depending on plan and explicitly covers the monthly service charge. Spectrum has historically kept prices consistent without a formal lock, but with no guarantee either. The key differentiator for T-Mobile home internet is no promotional pricing to begin with — most cable providers offer 12-month introductory deals that then jump significantly, while T-Mobile starts at the real price with the lock already in place. The honest caveat from independent telecom analysts: most carrier “price locks” protect base rates, not total bills, and T-Mobile’s is no exception.
The Two T-Mobile Price Locks — Side by Side
Before reading anything else in this guide, confirm which version applies to your account. The two work differently, cover different products, and were introduced at different dates.
For home internet customers
Excludes: taxes, fees, AutoPay discounts, voluntary upgrades, add-ons, third-party services.
For wireless phone plan customers
Excludes: taxes, fees, hotspot add-ons, streaming subscriptions, international charges, device payments, AutoPay discounts, satellite connectivity.
Between January 18 and April 22, 2025, T-Mobile offered a version of Price Lock that only promised to cover your final month’s recurring service charges if T-Mobile raised rates and you chose to leave. That version — called the “Last Month Price Lock” — was replaced by the stronger 5-Year Price Guarantee for new activations on Experience plans after April 23, 2025. If your account falls in the January–April 2025 window, check your plan confirmation carefully, because the protection is narrower than what’s now advertised.
T-Mobile Home Internet Plans with Price Lock
All three main plans and both AWAY plans carry the 5G Internet Price Lock. Prices shown with AutoPay. The $5 AutoPay discount is excluded from the lock — if you turn AutoPay off, that $5 comes back.
| Plan | Alone (AutoPay) | With Voice Line | Price Lock | Typical Download | Notable Extras |
|---|---|---|---|---|---|
| Rely | $50/mo | $35/mo | 5-Year (60 mo) | 133–415 Mbps | Standard 5G gateway · T-Mobile Tuesdays |
| Amplified | $60/mo | $45/mo | 5-Year (60 mo) | 170–498 Mbps | Wi-Fi 7 gateway · T-Mobile Tuesdays |
| All-In | $70/mo | $55/mo | 5-Year (60 mo) | 170–498 Mbps | Wi-Fi 7 · Hulu · Paramount+ · Mesh extender · 24/7 video support · Gateway upgrade at year 3 |
| AWAY 200GB | $110/mo | — | 5-Year (60 mo) | 118–402 Mbps | Portable · 200 GB high-speed · Pause option $10/mo |
| AWAY Unlimited | $160/mo | — | 5-Year (60 mo) | 118–402 Mbps | Portable · Unlimited data · Pause option $10/mo |
| T-Mobile Fiber 2 Gig | $70/mo | Varies | 5-Year · Founders Club: 10-Year | 2,000 Mbps symmetric | Select markets · No equipment fee · Symmetrical upload |
T-Mobile charges a one-time $35 device connection fee at activation. There is no monthly equipment rental charge — the gateway is included at no extra cost, and T-Mobile does not charge an installation fee for home internet (self-install takes about 15 minutes via the T-Mobile Internet app). The $35 one-time fee is not covered by the price lock because it’s a charge you pay once at activation, not an ongoing rate. Keep your receipt; it’s the only upfront cost that typically shows up on the first bill alongside your prorated service charge.
T-Mobile Wireless Plans with 5-Year Price Guarantee
The Experience plans replaced T-Mobile’s Go5G lineup starting April 2025. All carry the 5-Year Price Guarantee on the base talk, text, and 5G data rate. Taxes and fees are billed separately and can change.
| Plan | 1 Line | 3 Lines (each) | Price Guarantee | Hotspot | Streaming |
|---|---|---|---|---|---|
| Essentials | $60 | ~$40 | 5-Year | Limited | None |
| Experience More | $85 | ~$50 | 5-Year | 60 GB | Netflix Standard + Apple TV+ |
| Experience Beyond | ~$100 | Varies | 5-Year | 250 GB | Netflix + Apple TV+ + Hulu + more |
| Better Value (family) | Family only | ~$46 | 5-Year | Included | Netflix + Hulu + Apple TV+ |
How T-Mobile’s Price Lock Compares to Other Providers
Every major ISP and wireless carrier now markets some version of a price guarantee. They do not all mean the same thing.
| Provider | Lock Length | What’s Frozen | Taxes/Fees Included? | No Contract? |
|---|---|---|---|---|
| T-Mobile (Home Internet) | 5 years | Base internet service rate | No — excluded | Yes |
| T-Mobile Fiber (Founders) | 10 years | Base internet rate | No — excluded | Yes |
| Xfinity (Comcast) | 5 years | Base internet rate | No — excluded | Varies by plan |
| Verizon Fios | 2–5 years | Monthly service charge | No — excluded | Yes on most |
| Optimum | 3–5 years | Base internet rate | No — excluded | Yes |
| Spectrum | No formal lock | Historically consistent | No guarantee | Yes |
Find Your Situation
Check three things before calling. First, confirm your activation date and which plan version you’re on — the price lock only protects customers on qualifying plans activated after the specific dates that apply to each version. Second, look at whether taxes or government fees changed in your area; those are explicitly excluded from the lock and can rise regardless. Third, check whether the AutoPay discount was removed — if your payment method changed or expired, the $5 AutoPay discount disappears and your bill rises by that amount without any rate violation. If none of those explain it, call T-Mobile at 611 from your device and ask them to explain every line on your bill against your plan’s lock terms. Request a callback if hold times are long.
T-Mobile’s Rely plan at $50/mo standalone — or $35/mo if you have a T-Mobile voice line — is one of the most transparent pricing offers available for fixed-income households. There’s no promotional rate that jumps after 12 months, no equipment rental fee, and no annual contract. The 5-year price lock means you won’t face a surprise increase for 60 months after sign-up. The one-time $35 device connection fee is the only upfront cost. For seniors without a T-Mobile voice line who want the lowest price, the 55+ phone plan starts at $30/mo per line for two lines and brings the Rely home internet rate down to $35/mo when bundled. Check the T-Mobile 55+ plans at T-Mobile stores or by calling to confirm current eligibility terms.
For home internet activated after December 11, 2024, yes — T-Mobile’s published FAQ describes the 5G Internet Price Lock as a freeze on your fixed-wireless internet service price for 60 months, not a “last month free” escape clause. Independent telecom analysis confirms this is a genuine base rate freeze, not promotional pricing that expires. The caveats to know upfront: your total bill can still rise if local taxes change, if you cancel AutoPay, or if you add optional services. T-Mobile also offers a 15-day test drive — if the 5G signal at your address isn’t strong enough, return the gateway within 15 days for a full refund. A $750 contract buyout is available to cover early termination fees you may owe your current cable provider.
T-Mobile’s 2026 migration of legacy customers (Magenta, T-Mobile ONE, Simple Choice, Sprint grandfathered plans) moved affected accounts to Experience plans. The official statement said customers would “gain a 5-year price guarantee” as part of the move. However, independent analysis of these migrations noted the guarantee’s start date is the current account’s activation, not a reset to day one — meaning some migrated accounts may already be partway through their protection window. If you received a migration notice, call T-Mobile and ask specifically: “What is the start date of my 5-Year Price Guarantee, and what is my locked rate?” Get that answer confirmed in writing via email or by checking the My T-Mobile account page. If you opt out of arbitration over the terms of the migration, T-Mobile’s terms include a deadline for doing so — look for that language in the migration notice.
Yes. T-Mobile’s published FAQ confirms the 5-Year Price Guarantee applies to new lines of the AWAY plan as of accounts activated after the qualifying date. The AWAY 200GB plan at $110/mo and AWAY Unlimited at $160/mo both carry the lock on the base rate. Snowbirds and seasonal travelers benefit from the pause feature: service can be paused for up to 90 days at a time for $10/mo, twice a year. The lock applies to the active-service price, not the paused rate. If fiber is available at your primary address, T-Mobile Fiber and the AWAY plan can be used as a combination — fiber at home, AWAY while traveling.
You have more leverage than you might expect. T-Mobile wants to keep customers, and its current published rates for new sign-ups are generally similar to or lower than what customers have been paying under a 5-year lock. Call T-Mobile about two months before your lock expires and ask what your options are — whether there is a new plan with a fresh lock, whether your current rate would continue, or whether switching to a different tier gives you better value. Also check current competitor pricing from Optimum, Spectrum, Verizon Fios, or whatever local fiber provider serves your area. Having a specific competitor quote gives you negotiating context even if you don’t want to switch. There is no early termination fee, so your timing is entirely your own.

T-Mobile Phone Numbers and Resources
Dialing 611 from a T-Mobile phone is always the fastest path to account-specific answers about your price lock terms.
Log into your My T-Mobile account at t-mobile.com, navigate to your plan details, and look for the Price Lock or Price Guarantee designation alongside your plan name. If you don’t see it listed there, call 611 and ask the agent to confirm your plan’s lock terms, start date, and the specific rate that is protected. Ask them to send you an email confirming those details. That email becomes your documentation if a billing dispute arises within the 5-year window. The FCC’s consumer complaint page at fcc.gov/consumers/guides/filing-informal-complaint is available if you believe your price lock terms are not being honored and a call to T-Mobile doesn’t resolve it.
Price lock terms on this page reflect T-Mobile’s published FAQs, plan pages, and official press releases verified September 2026.
