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 and put the SIM into your device to get started.

If you don't want a new phone, but your current contract is up, then SIM Only is perfect. 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. Simply send a text to switch to Three and keep your number.
