Bill Pay SIM only plans.

A SIM only plan is a short term contract without a mobile phone. Because there's no phone, you get even better value on our plans and you only need to give 30 days notice if it’s not for you.

"You'd be mad not to go for Three". Nick Webb, Sunday Independent. Read More.

Our best selling plan gives you all the benefits of Three; plus you get to keep your phone and your number. You get oodles of calls and texts, and you get all you can eat data for a price that won't make you have kittens. So why don't you switch to Three and kick back with our €20.33 SIM only deal, so good that it will put the cat amongst the pigeons.

Switching to Three - things to know.

• Keep your number & your phone - You can keep your old number and your existing phone when you move to SIM only
• Network checker - It's best to check your phone will work on our Three network. Simply free text "Check" to 50100
• Unlock your phone - If you bought your phone from another network, you might need to get it "unlocked" before you can use it with a Three SIM. To do this you'll need to get in touch with your old network and ask them (nicely) for an unlock code so you can use it on Three.
