Paying for a full year of phone service in one shot can feel like a big leap. You’re used to a monthly bill that shows up, gets paid, and disappears into the background. Swapping that for a single upfront payment raises a fair question: are 12-month phone plans actually worth it, or are you just prepaying for something you could have paid for in smaller pieces?
The short answer: for a lot of people, yes, and by a wide margin. But it depends on three things: how predictable your usage is, whether the network works well where you live, and how comfortable you are committing to a year. This guide covers the real numbers on Infimobile’s 12-month plans, when the math works for you, and how to reduce the risk before you buy.
Limited-time bonus: if you’re planning to bring your number over, Infimobile is currently offering one month free on the 15GB, 20GB, and FREEDOM Unlimited 12-month plans when you complete a port-in and apply coupon code PORTFREE. The offer runs September 23 through October 7, 2026, and the details are covered below.

What Is a 12-Month Phone Plan?
A 12-month phone plan is a prepaid plan where you pay for a full year of service upfront. In return, you typically get a much lower effective monthly cost than you’d pay billing month to month, and you don’t have a monthly bill to manage for the rest of the year. Each month during the term, you get the plan’s data allotment, and it refreshes every 30 days, just like any monthly plan.
The Real Numbers: What 12-Month Plans Cost Per Month
Here’s how Infimobile’s current 12-month lineup breaks down on the plans page, with the effective monthly cost worked out for each:
| Plan Name | Plan | Plan Details | 12month Price | Permonth | Original Price |
| Deal Buster | 500MB | 100 mins / 100 SMS | $30 | ~$2.50 | $60 |
| Pro Plus | 5GB | 2,500 mins / 2,500 SMS | $75 | ~$6.25 | $180 |
| Unlimited Plan | 10GB | Unlimited | $75 | ~$6.25 | $252 |
| Promotional Plan | 15GB | Unlimited | $150 | ~$12.50 | $300 |
| Premium Plan | 20GB | Unlimited | $120 | ~$10.00 | $372 |
| Freedom Unlimited | Unlimited data, speeds reduced after 40GB | Unlimited | $175 | ~$14.58 | $480 |
Every plan runs on 5G/4G LTE, and the plans page displays a struck-through regular price next to the current 12-month price. Promotions change, so treat the numbers above as a snapshot and confirm current pricing at infimobile.com/plans before you buy.
Two things stand out. The 5GB Pro Plus and the 10GB Unlimited Plan carry the same 12-month price, but the 10GB plan includes more data and unlimited talk and text. And the 20GB Premium Plan currently costs less than the 15GB Promotional Plan. Compare what’s included rather than assuming a bigger number means a higher price.
Limited-Time Bonus: 1 Month Free When You Port In
For a limited time, Infimobile is adding a free month on top of the annual pricing above for customers who bring their number over from another carrier. Here’s the offer at a glance:
| Offer | One month free on your plan |
| Coupon code | PORTFREE |
| Offer period | September 23 – October 7, 2026 |
| Eligible plans | 15GB Plan, 20GB Plan, or FREEDOM Unlimited Plan (12 months) |
To qualify, you need to do three things: purchase an eligible 12-month plan, complete the port-in process, and apply the coupon code. Miss any one and the free month won’t apply. You only need to apply one code.
What is a free month worth? Measured at each plan’s effective monthly cost, roughly $12.50 on the 15GB plan, $10.00 on the 20GB plan, and $14.58 on Freedom Unlimited. That’s a genuine bonus, but choose the plan that fits your usage first, since a poorly fitting tier costs more than a free month saves.
Already an Infimobile customer? You can still take part. Existing customers can add a new line that meets every requirement: an eligible plan, a completed port-in, and the coupon applied. The offer applies to the new line, not to lines you already have.
Tips to make sure it counts: gather your old account number, transfer PIN, and billing ZIP code before you start; keep your old line active until the port completes, and start well before October 7. Most ports finish within a few hours to about 24 hours, with 48 hours as a reasonable outside estimate.
How to Tell If a 12-Month Plan Beats Paying Monthly
You don’t need a spreadsheet to answer this. You need one number: what you pay per month right now, including taxes and fees.
The break-even formula: annual plan price ÷ your current monthly bill = the number of months of use it takes for the annual plan to come out ahead.
Here’s an illustration, using a hypothetical $35 monthly bill (plug in your own):
- 10GB Unlimited Plan at $75: pays for itself in about 2.1 months
- 20GB Premium Plan at $120: about 3.4 months
- 15GB Promotional Plan at $150: about 4.3 months
- Freedom Unlimited at $175: 5 months
After that point, every remaining month of the year is effectively savings. Over a full year, that hypothetical $35 bill adds up to $420, compared with $75 to $175 on these plans.
There’s a flip side. The 5GB, 10GB, 15GB, 20GB, and Freedom Unlimited plans are labeled non-refundable on the plans page, so leaving early means you’ve paid for months you won’t use. If you bought the $150 plan and left after four months, you’d have paid the equivalent of $37.50 a month for the time you used it. On the $75 plans, the same early exit works out to about $18.75 a month. That’s the real risk of an annual plan, and it’s why the rest of this guide focuses on making sure the plan fits before you commit.
When a 12-Month Plan Is Worth It
Annual plans tend to make the most sense when:
- Your usage is predictable. If you know roughly how much data you use each month, you can pick a tier that fits and stop thinking about it.
- You want to pay once and be done. No monthly bill and no auto-pay to track.
- You’re adding a low-cost line. A second number for a family member or student is easy to manage as a fixed-cost plan.
- You’re already confident in the network. If you’ve tested coverage at home, at work, and on your regular routes, the main uncertainty is already gone.
When It Might Not Be Worth It
A 12-month plan isn’t the right move for everyone. It’s worth pausing if:
- You’re not sure you’ll stay a full year. With non-refundable plans, the savings only materialize if you actually use the term.
- You haven’t checked coverage. A great price doesn’t help if the signal is weak where you spend your time.
- Your data use swings wildly. A single fixed tier can leave you overpaying in light months or hitting reduced speeds in heavy ones.
- A large upfront payment strains your budget. Even a low effective monthly cost still requires paying the full amount upfront.
Details That Change the Value
The price-per-month math is only part of the picture. These plan details can change which option is the best value for you:
- Data and reduced speeds. After you use your monthly 5G/4G data, speeds are reduced for the rest of that month rather than you being charged overage fees. On Freedom Unlimited, that reduction applies after 40GB.
- Talk and text. The 10GB, 15GB, 20GB, and Freedom Unlimited plans include unlimited nationwide talk and text. Pro Plus includes 2,500 minutes and texts, and Deal Buster includes 100 of each.
- Hotspot. Freedom Unlimited currently shows a free 12-month hotspot add-on, up to 10GB per month. On the 5GB, 10GB, 15GB, and 20GB plans, hotspot is available as an add-on.
- Wi-Fi calling and texting. Included on every plan, which helps where cellular signal is weak.
- SIM options. Most plans come with a 3-in-1 SIM card kit, while Deal Buster is delivered digitally.
- Network choice. Infimobile runs on T-Mobile and Verizon, and you pick your network at sign-up, which can matter for coverage in your area.
- Taxes and fees. These may apply depending on where you live, so check the total at checkout.
Plan by Plan: Who Each One Fits
Deal Buster (500MB, $30/year). The lowest-cost entry point, built for very light use. With 500MB of data and 100 minutes and texts, it fits a secondary number rather than a primary phone.
Pro Plus (5GB, $75/year). A step up for someone who mostly relies on Wi-Fi and uses cellular for maps, messages, and occasional browsing. Keep in mind the 2,500-minute and text caps, and that hotspot is an add-on.
Unlimited Plan (10GB, $75/year). Priced the same as the 5GB plan, with more data and unlimited talk and text. For many light-to-moderate users, it’s the more flexible of the two at the same price.
Promotional Plan (15GB, $150/year). Suits someone who uses cellular data regularly, such as streaming on the commute, but doesn’t need the highest tier. Eligible for the 1-month-free offer with a port-in.
Premium Plan (20GB, $120/year). More data than the 15GB plan at a lower annual price, which makes it worth a close look if you’re considering anything above 10GB. Also eligible for the offer.
Freedom Unlimited ($175/year). Built for heavy users and anyone who tethers a laptop or tablet. It includes unlimited data with speeds reduced after 40GB, unlimited talk and text, and a free 12-month hotspot add-on of up to 10GB per month. Also eligible for the offer.
How to Lower the Risk Before You Commit
Most of the risk comes from uncertainty. A few steps remove most of it:
- Check coverage at your address. Use the coverage and compatibility checker at infimobile.com/compatible, and cross-check T-Mobile’s and Verizon’s public coverage maps for your ZIP code, since Infimobile’s service quality follows whichever network you choose.
- Confirm your phone is compatible. You’ll need an unlocked device that supports 5G or 4G LTE and VoLTE. Dial *#06# to find your IMEI, then enter it in the compatibility checker.
- Test before you port. Infimobile offers a trial port-in option in the account portal, letting you try service on a temporary number first. The free-month offer is tied to completing your actual port-in on an eligible plan, so the trial is a separate step.
- Look at your real usage. Check the last few months of data use on your current plan, so you pick a tier based on habits, not guesses.
- Ask before you buy. If anything in the plan terms is unclear, Infimobile’s support team is reachable at +1 (855) 484-1855 or +1 (678) 608-1414, or by email at support@infimobile.com.
Frequently Asked Questions
On a per-month basis, generally yes. Paying for a full year upfront typically lowers the effective monthly cost, and on Infimobile’s lineup that cost ranges from about $2.50 to about $14.58 a month depending on the plan. Divide the annual price by your current monthly bill to see how quickly a plan pays for itself.
Your speeds are reduced for the rest of that month’s cycle rather than you being charged an overage fee. Your high-speed data then resets at the start of the next monthly cycle within your 12-month term. On Freedom Unlimited, speeds are reduced after 40GB of 5G/4G data.
The 5GB, 10GB, 15GB, 20GB, and Freedom Unlimited plans are labeled non-refundable on Infimobile’s plans page, so you generally shouldn’t expect a refund for unused months. Read the terms before purchasing, and contact Infimobile support if you have questions about your situation, including the Deal Buster plan.
Purchase the 15GB Plan, 20GB Plan, or FREEDOM Unlimited 12-month plan, complete the port-in process, and apply coupon code PORTFREE. The offer runs September 23 through October 7, 2026. Existing Infimobile customers can qualify too by adding a new line that meets all three requirements.
Yes. You can port your existing number in from another carrier instead of starting with a new one. Have your old account number, transfer PIN, and billing ZIP code ready, and keep your old line active until the port completes so you don’t lose the number.
The Verdict
So, are 12-month phone plans worth it? If you have a reasonably predictable usage pattern, you’ve confirmed coverage where you live, and you’re comfortable paying upfront, the numbers are hard to argue with. Effective monthly costs on Infimobile’s lineup range from about $2.50 to about $14.58, and you get a year of rate certainty on top. If you’re porting a number to one of the three eligible plans before October 7, the free month with code PORTFREE adds a bonus.
If you’re unsure about coverage or how much data you really use, resolve those questions first: check coverage, confirm compatibility, and consider the trial port-in. After that, the only question left is which tier fits how you use your phone.
Twelve months is a long time to commit to anything, so do the homework first: check coverage, confirm your device works, and pick the tier that fits your real usage. If that’s the 15GB, 20GB, or Freedom Unlimited plan and you’re bringing your number over before October 7, use code PORTFREE at checkout to add a free month. Questions?
