Between the rolling thirty day plans and the two year ones sits a middle option that gets overlooked. The twelve month term fixes a price for a year, runs without a credit check, and still renews in thirty day cycles. For anyone who finds two years too long and a month too short, it is the part of the range worth reading properly.
The Five Plans at Twelve Months
UK Plan Smart 12 Month
Five gigabytes at four pounds fifty per thirty days. EU roaming included, a thousand UK calls and texts, eSIM available. The lightest option, and the only one here without unlimited UK calling.
National Plus 12 Month
Thirty gigabytes at nine pounds. Unlimited UK calls and texts, a hundred international minutes free, eSIM available. Six times the data of Smart for four pounds fifty more, which mirrors the jump on every other term.
UK Plan Super Extra 12 Month
Seventy five gigabytes at thirteen pounds fifty. Unlimited UK calls and texts, eSIM available, and data roaming covering the EU, China and India. That last line is the one that separates this plan from everything around it.
UK Plan Mega Plus 12 Month
A hundred and twenty gigabytes at eighteen pounds. Unlimited UK calls and texts, a hundred international minutes free, eSIM available. Forty five gigabytes more than Super Extra for four pounds fifty.
UK Plan Unlimited 12 Month
Unlimited data at twenty two pounds fifty. Unlimited UK calls and texts, a hundred international minutes free, eSIM available. The top of the twelve month list.
Where Twelve Months Sits
On every single tier, the twelve month price falls between the thirty day listing and the twenty four month one. Smart runs three pounds fifty, four fifty, then four pounds. National Plus runs five, nine, then eight. Super Extra runs seven fifty, thirteen fifty, then twelve.
Read that sequence carefully, because it does not do what you expect. On Smart, National Plus and Super Extra the twenty four month price is lower than the twelve month one, so the longer term is the better deal of the two. The twelve month option is not the value choice. It is the commitment choice, for people who want a fixed price without agreeing to two years of it.
Mega Plus and UK Plan Unlimited follow the same shape. Mega Plus runs ten pounds on thirty days, eighteen on twelve months and sixteen on twenty four. The unlimited plan runs twelve pounds fifty, twenty two fifty and twenty. In both cases the two year figure undercuts the one year figure, and in both cases the thirty day price is the lowest of the three because it is discounted for the first month only.

What You Are Actually Fixing
A price, and nothing else. There is no handset, no contract and no exit fee, because there is nothing to exit. The line renews every thirty days exactly as a rolling pay as you go plan does, and what the term buys is the guarantee that the figure will not move for a year.
The no credit check position is the other half of it. Nothing is run against your file, which makes this workable for people a contract would decline and for anyone setting a line up on someone else’s behalf.
Who Should Take It
Students on a course of a known length, people on a visa with an end date, anyone setting up a line for a year abroad or a year at home before a move. The term matches the circumstance, which a two year arrangement would not.
For everyone else the question is simpler: if you are happy to fix a price at all, the two year version of the same SIM only plan is usually a little lower. If two years feels like guessing, this is the one to take.
eSIM availability runs across all five, which matters more on a fixed term than on a rolling one. Starting a year long arrangement should not involve waiting for the post, and it does not have to. The prepaid plan can be live the same day you choose it.
Weighing It Up
Twelve months fixes a price for a year with no credit check and no contract, at a figure that sits above the two year rate on most tiers. Take it when the year is the point, not when the price is.
All three lengths get repriced independently, which is exactly why their ordering keeps surprising buyers. Each movement is tracked at BlogsBuddy. Annual SIM arrangements come from Lyca Mobile.
