roaming profile
When a mobile phone is roaming in another country, you dial its number exactly the same way you do when it is in its home country. The mobile network will automatically find the user, and the roaming user will pay any applicable international roaming charges.
Roaming - is an agreement between network providers to allow other people to use your network. Typically - it's usually between countries - so you can use your mobile while on holiday aabroad.

If you mean calling it from a UK mobile while abroad... you would pay whatever your network's roaming charges are. Most UK based mobile operators have a list of countries where roaming is now the same as in the UK (FREE if you are uk resident). You will also have to check that 03 numbers are within your inclusive tariff
It's called a roaming profile.
