T-Mobile is dangling one of the most aggressive home broadband promos on the market right now: a free month of 5G Home Internet service paired with up to $300 back via a virtual prepaid card. For households frustrated with cable price hikes or sluggish DSL, that combination of upfront savings and longer term bill stability can be enough to justify a switch. I see this as a rare chance to test-drive a full replacement for your current provider with very little financial risk.
The core pitch is simple. You sign up for T-Mobile’s 5G Home Internet online, get your first month credited, then claim a rebate worth as much as $300 once your line is active and your code is registered. The details matter, though, from how the rebate tiers work to when the deal ends, so it is worth walking through the fine print before you cancel your existing connection.
What T-Mobile’s 5G Home Internet deal actually includes
At the center of the offer is T-Mobile’s fixed wireless service, which uses the company’s 5G and 4G network to replace a traditional cable or fiber line. The carrier positions its 5G Home Internet as a simple, flat-rate alternative with no annual contract and a price lock that can stretch for years, which is why a month of free service plus a sizable rebate stands out as more than a short-term teaser. The official product page for home internet lays out the basics, including the plug-and-play gateway that connects your phones, laptops, smart TVs, and consoles over Wi‑Fi.
The current promotion layers on top of that baseline. T-Mobile is advertising a “Month On Us and up to $300 back” when you sign up online for qualifying 5G Home Internet plans, framing it as a limited-time incentive to move quickly. The company also leans on independent testing, noting that, according to According to Ookla Speedtest results, its network ranks among the fastest 5G home internet options, which is crucial if you plan to stream 4K video or run multiple video calls at once.
How the free month and up to $300 back work
The free month is the straightforward part. When you order a qualifying 5G Home Internet line online, T-Mobile applies a bill credit that effectively wipes out your first month of service, letting you test the connection under real-world conditions. The more complex piece is the rebate, which is structured as a virtual prepaid card worth up to $300 that you receive after activating service and submitting your information. One detailed breakdown of the deal explains that the combination of a free month and a rebate of up to $300 is what makes the offer competitive with traditional cable sign-up bonuses.
To actually get the money, you need to follow the redemption steps carefully. After your line is active, you register a promo code within a set window, then wait for the virtual card to arrive by email. Guidance on how to redeem notes that the rebate can take up to 14 weeks from submission to process, so this is not instant cash, but it is a meaningful offset to your early bills. The same walkthrough stresses that you must submit your claim correctly and on time to avoid delays, which is why I always recommend reading the instructions on how to redeem your cash back before you even plug in the gateway.
The rebate tiers: $100, $200, and $300
Behind the “up to” language is a tiered rebate structure that ties the size of your virtual card to the specific home internet plan you choose. T-Mobile spells out that you must Register your code within 30 days of activating a qualifying new Internet line, and that the rebate amounts are $100 for the Rely tier, $200 for Amplified, and $300 for the top All option. That means not every customer will walk away with the full $300, but the higher-end plans effectively come with a larger sign-up bonus.
Other deal trackers echo that structure, describing the offer as an online-only promotion that gives you up to $300 back via virtual prepaid card when you order eligible home internet service. The same pages highlight that this is an ONLINE EXCLUSIVE, and that the setup is designed to be Easy to install and Order from home, which matters if you are trying to avoid technician visits or long store lines.
Key fine print: timing, eligibility, and the virtual card
As with any aggressive promotion, the calendar and eligibility rules are critical. Coverage of the current campaign notes that the free month and rebate combo is set to end on Feb. 25, 2026, although deals can sell out or change earlier, so you should treat that as a soft deadline rather than a guarantee. One overview of the offer spells out that the promotion is limited-time and that Deals are always subject to early expiration, which is why I would not wait until the last day if you are serious about switching.
The rebate itself arrives as a virtual prepaid card, not a paper check, which affects how and where you can spend it. One explainer describes T-Mobile’s Virtual Prepaid Mastercard a Real Steal for a limited time, but it also notes that the card typically expires after several months and must be used where major card networks are accepted. Another breakdown of a similar promo points out that a $300 g virtual card can expire in about six months, so I would plan to apply it quickly to streaming subscriptions, a new router, or even a month or two of your existing provider while you test T-Mobile.
How this stacks up against other T-Mobile internet deals
One way to judge the value of the current promotion is to compare it with other T-Mobile home internet incentives that have rolled out over the past year. Earlier offers have included a flat $300 virtual card for new sign-ups, as well as targeted deals that gave existing wireless customers extra savings when they added home internet. A recent roundup of Mobile Deals and notes that you can still Get up to $300 back on select Mobile 5G Home Internet plans, which suggests that the company is using rebates as a consistent tool to lure cable switchers.
Independent trackers of Top Mobile Internet Plans also highlight a $200 rebate via Virtual Prepaid Mastercard for the Rely Home Internet plan, which is a 5G Internet service priced at $50 per month with AutoPay. When you line that up against the current “Month On Us” plus up to $300 back, it is clear that T-Mobile is stacking multiple incentives at once, especially for the higher tiers, to make its 5G gateway a more compelling alternative to a coaxial cable modem.
