SMARTY prices, quoted from SMARTY's own page
SMARTY is the clearest publisher in this record and by some distance. Its SIM only page prints a complete ladder with calls and texts, a second complete ladder for data only, and the price of a data add-on when you run out, all as plain text on a page that answers a plain HTTP read. The figures below were fetched from that page and matched word for word on the date shown.

Which plan types this seller prices
Taken from the seller's own page, which states the plan and the term. We do not credit a plan type to a seller on the strength of a marketing claim.

What the two ladders show
With calls and texts the ladder runs Unlimited £20, 200 GB £17, 150 GB £15, 100 GB £12, 40 GB £10, 20 GB £9, 16 GB £8, 5 GB £6, all rolling monthly with no tie. Data only runs Unlimited £20, 100 GB £17, 40 GB £13, 15 GB £9, 2 GB £5.
Reading them together is the useful part and it produces a counterintuitive result: at 40 GB the data-only plan is £13 against £10 for the same data with calls and texts, and at 100 GB it is £17 against £12. Removing the calls makes the plan more expensive at every tier the two ladders share.
The line nobody else prints
The page states that if you run out of data during the month, an add-on will cost just £1 per GB, and that this is the same amount you pay for data in your usual plan. That single sentence answers the question that decides whether a cheap plan stays cheap, and no other seller in this record answers it on the page we read.
