What is a SIM Only deal?

A SIM Only contract is just that. No phone or tablet, just a SIM card with all the data, minutes and texts you need. Pick a Pay Monthly or Pay As You Go plan that suits you. You get extra flexibility with Pay Monthly, because you can join us on a 1, 12 or 24-month plan. And if you choose Pay As You Go there's no upfront cost.
