Calling Abroad, Country Codes and International Dialling
When making an international call, two extra codes must be added to the beginning of the phone number to ensure a successful connection: the exit code and the country code.
Exit Code
This is the code at the start of the number that tells the network that you wish to call someone outside of the country you are currently located in. In most cases, this code can be represented by dialing '+'.
Country Code
This code identifies the home country of the number that you are calling. If you are calling a mobile number, it is that mobile subscriber's home country regardless of where they are currently located in the world.
Examples
If I you are in the UK and want to ring someone in the US, you need to add +1 or 001 to the start of their phone number
If you are in Germany and want to ring someone in Hong Kong, you would add +852 or 00 852 to the start of their phone number
Callback Method
In a small number of countries, some network providers block our customers from making outbound calls. This can be easily resolved by using the callback method. Find out how to do this here.
