If you live in the USA and have made international calls at one point then you understand the process. To dial any number outside of North America (international) you must dial the numbers 011 before the country code, city code and seven digit phone number. For example, if I was to dial the United Kingdom from a USA mobile phone or land line phone I would dial 011(international access number),44(UK country code), 171 (city code for London) and 555-1212 (the local phone number that I want to reach in the UK. Now, from any other location outside of the USA you do not use 011 to prefix the call. If you wanted to direct dial the same number above while calling from let’s say, Germany, the pattern would be as follows. 00( two zeros lets the mobile know that you are going to be placing an international call), 44 (country code), 1710(we now add a zero after the city code as required in Europe) and the seven digit phone number of 555-1212.
