Here is how it works: you purchase a UK prepaid sim card for your phone, we send it to you here in Australia, you put it on your phone as soon as you land in the UK, wait a few minutes for it to activate and then you are all set. It’s prepaid and there is no contract. You will enjoy a generous allowance of high speed data as well as calls and text messages. You will even be able to use your UK prepaid sim card in 34 European countries including France, Italy, Ireland and Spain. Almost all phones are compatible with the UK sim card including all iPhones and most other recent models of smartphones.
