In Australia

[Jeff1]

I will be in Australia for a month. If someone in the UK wants to phone me on my Three mobile phone when I am there, what numbers do they start dialling with?

If you are using your Three UK SIM, roaming in Australia, someone dialling it would just dial your number as if you are in the UK, probably just hear a different ring tone.  However, since you are roaming, to dial someone back in the UK you would need to use the UK international dialling code ie 004476XXXXXXXX

To check the roaming charges in Australia, use this link - https://www.three.co.uk/support/roaming-and-calling-abroad/roaming-abroad?country=Australia

I think this is a more accurate description of what’s needed rather than mine!

They’d need to start with the country code which is 0061 then your mobile number but omitting the first zero. So for example if your number was 07788999000 they would need to dial 0061 7788999000.
