Annual plan

An annual plan is a cell phone plan you pay for in a single up-front payment for 12 months of service, typically at a 30–50% discount compared to the equivalent month-to-month plan. Annual plans are most common at prepaid MVNOs (Mint Mobile is famously annual-first) but are increasingly available at larger prepaid carriers and some MVNOs that started monthly.

Where annual plans win

• Per-month price: Mint Mobile's 12-month unlimited plan averages around $30/month vs. $40/month on a 3-month plan. US Mobile, Tello, and Red Pocket offer similar discounts. Visible has occasional annual deals.
• Set-it-and-forget-it billing: one charge, then nothing for 12 months. No surprise bill increases mid-year.
• No auto-pay required: most annual plans don't need auto-pay, paperless billing, or other compliance hoops to get the advertised price.

Where annual plans lose

• If you switch carriers mid-cycle, you forfeit the unused months. Most MVNOs don't pro-rate refunds for unused annual time. Lock-in cost is real if you change your mind.
• If the carrier degrades or your usage changes, you're stuck until the year ends.
• If the carrier raises prices, your locked rate is good through the end of the term — but renewal might be at the new (higher) rate.

Should you pick an annual plan?

Yes, if: (a) you've used the carrier for 1+ months on monthly and like it, (b) your usage profile is stable, (c) the per-month savings are meaningful (typically $5–15/month), (d) you don't expect to switch in the next year. No, if: (a) you're trying a carrier for the first time — start monthly first, (b) you might travel internationally and need a different setup mid-year, (c) the savings vs. monthly is less than 20%.

The Mint Mobile model proved annual works at scale — Mint reaches millions of subscribers largely on the strength of the up-front-discount pricing model.
