Save with a SIM Only Deal

Switch to a Pay Monthly SIM contract and save money on your bill and enjoy increased flexibility due to shorter contract lengths. SIM Only contracts offer better value because the operators don't have to offset the cost of a mobile phone enabling you to get more minutes, data and texts for your money.

Shorter Contract Lengths

SIM Only plans are available on a 12 monyh or 1 month rolling contracts, which gives you a lot more flexibility compared to mobile phone plans which lock you into 24 month contracts.

  • 12 month plans - Perfect for those looking for the best value as they are the cheapest SIM deals you can buy.
  • 1 month rolling plans - Great for those looking for maximum flexibility. At the end of the month the plan will automatically renew (or roll) into the next month, unless you inform Three that you want to cancel.

Keep your existing number

When switching to a SIM contract keeping your existing number is easy even if you are on another network. Simply follow the steps here.
