Prepaid is usually sold as a monthly habit: pay, use, renew, repeat. The renewing is the part people quietly resent — a small task that arrives twelve times a year and occasionally gets forgotten until the phone stops working. Paying for a stretch up front removes it, and the rate for doing so is low enough that the convenience is not what you are paying for. A long term prepaid plan works out lower per month than the same allowance bought monthly, not higher.
Three of the data tiers can be bought in advance, in three, six or twelve month blocks. The allowance per month is unchanged; what changes is how far ahead you pay and how much comes off the total.
| Monthly allowance | 3 months | 6 months | 12 months |
|---|---|---|---|
| 8GB | Lists $69, now $21 | Lists $138, now $78 | Lists $276, now $108 |
| 15GB | Lists $87, now $30 | Lists $174, now $96 | Lists $348, now $120 |
| 18GB | Lists $99, now $30 | Lists $198, now $120 | Lists $396, now $144 |
Every block keeps unlimited nationwide talk and text and unlimited international talk and text to 100 countries, exactly as the monthly plans do.

Two things stand out. The first is that the twelve-month blocks are where the discount concentrates: the 15GB year lists at $348 and is currently $120, which is a different order of saving from the three-month version of the same plan. The second is that the 15GB and 18GB three-month blocks are both currently $30, so at that length the larger allowance costs nothing extra — if you are buying three months, buy the bigger one.
It is also worth doing the division. A twelve-month block divided by twelve gives the real monthly figure, and that is the number to compare against the monthly tiers rather than the total, which always looks larger because it is twelve payments collapsed into one. On the 8GB year that works out at nine dollars a month against a monthly list price of twenty-three, which is the comparison that actually decides it.
This suits someone settled: a steady address, a steady usage pattern, a number they intend to keep. It suits anyone who has previously let a plan lapse by forgetting, because the problem disappears for a year. And it suits a household buying for someone else — a parent, a student — where the renewal is one more thing to remember on another person's behalf.
It suits you less if your plans are uncertain. Paying twelve months ahead is the one place in prepaid where flexibility is traded away, and if there is a real chance you will leave the country or change networks inside the year, the monthly ladder keeps that door open at a modest premium. Three months is the sensible middle if you want some of the saving without the commitment, and it is the length most people should start on before stretching to a twelve month phone plan.
If your usage is stable and your number is staying, the twelve-month blocks are straightforwardly the lower-cost way to run the same line, and they retire the monthly renewal along with it. If anything about the year ahead is unsettled, take three months and revisit. Either way, work from the per-month figure rather than the headline total when you compare an annual prepaid plan against paying as you go.
