Your UK sim card is shipped to you with the UK mobile number included, so you'll know it before you leave for the UK. This means you can:
- Tell family, friends or work colleagues your UK mobile number;
- Update your travel details with hotels, airlines and tour operators so they can contact you on a local UK mobile number;
- Update your Smartraveller.gov.au details with your UK mobile number;
- Set up diversions from your home phone/mobile phone to your UK mobile number.
