If you’ve been eyeing a change from Mint Mobile, now might be the moment to make the jump. Infimobile, a prepaid wireless provider known for stretching a mobile budget further than most big-name carriers, has launched a port-in promotion that rewards new and existing customers with a full month of free service. Whether you’re tired of Mint’s after-promo renewal rates, want a plan that isn’t tied exclusively to one network, or you’re simply shopping around for a better deal, this offer is worth understanding in detail before you commit.
Below, we break down exactly how the promotion works, who qualifies, which plans are eligible, and how Infimobile stacks up as a genuine alternative to Mint Mobile.
Why People Are Looking Beyond Mint Mobile
Mint Mobile built its reputation on low, flat-rate pricing bundled into multi-month prepaid terms, running on T-Mobile’s network. It’s a solid option for many people, but it isn’t the only low-cost prepaid carrier worth considering. Some customers find that:
- Renewal pricing after an introductory period can climb noticeably higher than the rate they signed up for.
- Being locked into a single underlying network (T-Mobile) doesn’t always mean the best signal in every location.
- Multi-month upfront commitments don’t always match how much data a household actually uses.
Infimobile enters this conversation as a prepaid alternative that, depending on your ZIP code, runs on either the Verizon or T-Mobile network, giving customers in weaker T-Mobile coverage areas an option they may not have had with Mint. It also builds its plans around annual (12-month) prepaid terms with tiered data allowances, so people can pick a plan that matches their actual usage rather than paying for more data than they need.
The PORTFREE Offer: What You Need to Know
Here’s the offer as it stands right now.
Coupon Code: PORTFREE
Offer Period: September 23, 2026 – October 7, 2026
Eligible Plans (12-Month Plans Only):
- 15GB Plan – 12 Months
- 20GB Plan – 12 Months
- FREEDOM Unlimited Plan – 12 Months
How it works: Any customer who ports an existing phone number into Infimobile and purchases one of the three eligible 12-month plans, applying the coupon code PORTFREE at checkout, receives one additional month of service on the house. In practice, that means a customer who signs up for a 12-month term ends up with 13 months of coverage for the price of 12, a meaningful discount when you consider these plans are already priced well below flagship carrier rates.
This is a limited-time, port-in-specific promotion. That “port-in” requirement matters: it’s designed for people bringing an active phone number from another carrier like Mint Mobile, but also AT&T, Verizon, T-Mobile, or any other MVNO, rather than customers activating a brand-new number. If you’re planning to keep your current number when you switch, this offer lines up perfectly with that process.
Already an Infimobile Customer? You’re Not Left Out
One of the more customer-friendly aspects of this promotion is that it isn’t restricted to brand-new sign-ups only. Existing Infimobile subscribers can also take advantage of the free month, provided they add a new line that satisfies the same promotion requirements, meaning the new line still needs to be a qualifying 12-month plan (15GB, 20GB, or FREEDOM Unlimited), still needs to involve a ported-in number, and still needs the PORTFREE code applied at checkout.
This makes the promotion useful for households adding a second or third line for a partner, a teenager getting their first phone, or a secondary device without needing to abandon an existing Infimobile account to get the discount.
The takeaway: switch or add a qualifying line between September 23 and October 7, 2026, and you lock in an extra month of service at no additional cost.
Breaking Down the Eligible Plans
All three plans on offer run on Infimobile’s 12-month prepaid model, which front-loads the payment for a full year of service rather than billing monthly. This structure is part of how Infimobile keeps its effective monthly cost low; you’re essentially pre-paying for a year in exchange for a lower blended rate, similar in spirit to Mint Mobile’s multi-month plans, just stretched across a longer term.
15GB Plan (12 Months)
Built for people with moderate data needs, enough for regular social media use, maps and navigation, music streaming, and a reasonable amount of video. Once the monthly 15GB high-speed allotment is used up in a billing cycle, data typically continues but at reduced speeds until the next cycle begins. Talk and text are unlimited nationwide.
20GB Plan (12 Months)
A step up for heavier data users, people who stream more video, work some days remotely on a mobile hotspot, or simply don’t want to think about a data cap very often. Like the 15GB tier, speeds reduce after the monthly allotment is consumed rather than cutting off entirely.
FREEDOM Unlimited Plan (12 Months)
Infimobile’s top-tier offering, providing unlimited high-speed data with a much higher usage threshold before any speed reduction kicks in, plus unlimited nationwide talk, text, and MMS. This plan is generally aimed at people who don’t want to monitor data usage at all and use their phone as a primary hotspot or streaming device.
All three plans typically include:
- Access to either the Verizon or T-Mobile network, assigned based on coverage in your ZIP code
- A choice between a physical SIM card kit or eSIM activation
- Nationwide talk and text
- Wi-Fi calling and Wi-Fi texting.
- Optional mobile hotspot add-on (data allotment for hotspot use can typically be purchased separately or is bundled at a set amount on higher tiers)
Because Infimobile frequently adjusts promotional pricing on top of its published rates, the exact cost of each plan can shift from week to week. To lock in the current price alongside the PORTFREE month, it’s worth checking the live pricing on Infimobile’s plans page at the time of purchase rather than relying on an older quoted number.
How to Redeem the PORTFREE Offer
Switching carriers can feel like a hassle, but porting a number into Infimobile follows a fairly standard process:
- Gather your current account details. You’ll need your current phone number, account number with your existing carrier (Mint Mobile or otherwise), and in some cases a PIN or password associated with that account. Mint Mobile customers can typically find this information in their Mint account dashboard.
- Choose your eligible plan. Select the 15GB, 20GB, or FREEDOM Unlimited 12-month plan on Mint Mobile’s website.
- Choose SIM or eSIM. Decide whether you want a physical SIM shipped to you or want to activate instantly with an eSIM-compatible device.
- Enter the port-in details during checkout. This is where you confirm you’re bringing your existing number over rather than activating a new one.
- Apply the coupon code PORTFREE at checkout. Make sure the code is entered before finalising payment; most promo codes cannot be applied retroactively after purchase.
- Complete activation. Once your SIM or eSIM is active and the port-in completes (which can take anywhere from a few minutes to a couple of days depending on your previous carrier), your free month should be reflected in your account or added to your service term.
If your free month doesn’t automatically appear after the port-in completes, it’s worth reaching out to Infimobile customer support with your order confirmation and the coupon code you used.
Infimobile vs. Mint Mobile: A Practical Comparison
It helps to look at how these two prepaid carriers actually differ, beyond just the promotion itself.
Network access: Mint Mobile runs exclusively on T-Mobile’s network. Infimobile routes customers to either Verizon or T-Mobile depending on location, which can be an advantage if you live or work somewhere with historically weaker T-Mobile coverage but strong Verizon service, or vice versa.
Plan structure: Mint Mobile is built around 3-, 6-, and 12-month terms with a handful of data tiers. Infimobile leans more heavily on 12-month prepaid terms across multiple data tiers (5GB, 10GB, 15GB, 20GB, and unlimited), which tends to produce a lower effective monthly rate the longer the term you choose.
Switching incentives: Mint Mobile has run its own family of port-in promotions over the years, often bundling free additional lines or short-term discounts for new customers switching from AT&T or Verizon. Infimobile’s PORTFREE promotion plays a similar role but is structured as a straightforward “free extra month” rather than free additional lines.
Renewal pricing: With any prepaid annual plan Mint Mobile includes it’s common for the price to reset to a standard (non-promotional) rate once the introductory term ends. This is true of Infimobile’s plans as well, so it’s worth reading the fine print on what your plan renews at after the first 12 months, rather than assuming the promotional price is permanent.
Customer experience: Both carriers operate as no-contract, prepaid-first services, meaning account management, porting, and support are typically handled through an app or online portal rather than in physical retail stores.
Neither carrier is objectively “better” in every scenario; it comes down to which network performs better where you actually use your phone, how much data you realistically need, and whether a 12-month upfront commitment fits your budget better than Mint’s shorter terms.
Who Should Consider This Offer
This promotion is likely to appeal most to:
- Mint Mobile customers approaching a renewal date, especially if their current plan is about to reset to a higher non-promotional rate.
- Households wanting to add a line without switching their entire existing service, thanks to the existing-customer eligibility.
- People in areas with inconsistent T-Mobile coverage who want the option of being routed to Verizon’s network instead.
- Budget-conscious users comfortable with an annual prepaid commitment in exchange for a lower blended monthly cost.
It’s less suited to people who want month-to-month flexibility without any upfront commitment, since all three eligible plans are 12-month terms.
A Few Things Worth Double-Checking Before You Switch
Before committing, it’s worth confirming a few details directly with Infimobile, since promotional terms can include fine print that isn’t always obvious at a glance:
- Whether the coupon can be combined with any other active discount or referral code
- What the exact renewal price will be once the 12-month (or 13-month, with the bonus) term ends
- Whether taxes and regulatory fees are included in the advertised plan price or added separately at checkout (many prepaid carriers list a base price before applicable fees)
- Whether your specific device is compatible with Infimobile’s network and, if you’re choosing eSIM, whether your device supports it
- The porting requirements from your specific current carrier. Some carriers require you to unlock your account or clear a final bill balance before a port-out will succeed.
Taking ten minutes to confirm these details before checkout can save you a surprise later.
Frequently Asked Questions
No. While new customers switching from Mint Mobile or any other carrier can use the offer, existing Infimobile customers can also get the free month by adding a new line that meets the same requirements: a qualifying 12-month plan, a ported-in number, and the PORTFREE code applied at checkout.
Only three 12-month plans are eligible: the 15GB Plan, the 20GB Plan, and the FREEDOM Unlimited Plan. Shorter-term plans, other data tiers, and non-port-in activations are not part of this specific promotion.
A port-in means transferring your existing, active phone number from another carrier Mint Mobile, AT&T, Verizon, T-Mobile, or any other provider into Infimobile, rather than activating a brand-new number. The free month is tied specifically to this type of switch.
Like most annual prepaid plans, your service will typically renew at Infimobile’s then-current standard rate for that plan tier once the promotional term ends, rather than automatically continuing at the discounted rate you initially paid. It’s a good idea to check the renewal price listed for your specific plan before you sign up.
Coupon stacking rules vary by promotion and are set by Infimobile at checkout. Before assuming you can combine PORTFREE with another active discount or referral code, it’s best to try applying both during checkout or confirm directly with Infimobile customer support, since some promotions are designed to be exclusive.
Final Thoughts
Switching mobile carriers is rarely something people do on a whim, but a well-timed promotion can make the decision easier. Infimobile’s PORTFREE offer gives both new and existing customers a genuine, no-strings-attached incentive: an extra month of service for choosing one of its three annual plans and bringing an existing number along. If your Mint Mobile plan is up for renewal, or you’ve simply been curious about trying a carrier that can route you to either Verizon or T-Mobile depending on your location, this two-week window is a reasonable time to test the waters.
As with any prepaid promotion, the details matter more than the headline. Confirm current plan pricing, read the renewal terms, and make sure your device and current carrier situation are compatible with a clean port-in before you commit to a full year of service.
