UK Code Number

This is very off topic. But I have a good friend that lives in Cali, LA in the USA. She wants my Mobile number but I dunno what the code numbers are. Being in the states she can't just call my mobile number alone, she has to dial all that other silly stuff first. Anyone knows what it is or where i can find it- I am useless with numbers. :? :? :?

Hiya,

Your friend has to dial: 00 44 and then your mobile number without the first 0

IE if you phone number is 07777 123 456 then your friend dials 00 44 7777 123 456 (at least, this works from Europe.... I guess it works from the US as well).
