What's my phone number?
This SIM can receive calls! 📞Your phone number can be found on the back of the SIM when you receive it. It's indicated as "Your Three Number".
This is a UK mobile number, so to call it you need to dial the country code (+44) before the number.
For example: Your Three number - 071234567891 (yes, it's 11 digits)
Dial +44 7123456789 (dropping the 0)
Note: Your number will stay the same no matter which country you're in.
- Calling from a landline in Australia, dial 0011 44 71234567891
