Global roaming enables compatible mobile phones to make and receive mobile calls while overseas when in areas serviced by global roaming partners.
Global Roaming is not activated by default as ongoing costs are incurred.
Calling Card
The calling card allows you to make calls from landline phones while overseas, that are then charged back to your University of Adelaide department. Using a calling card is far cheaper than Global Roaming.

Using Calling Cards
Calling cards come with user instructions. Below is a copy of the user instructions and country pin codes.
There are four main GSM frequency bands used by mobile networks around the world. These are (with a rough list of regions):
850 MHz (USA/Canada/South America)
900 MHz (Africa/Europe/Australia/Asia)
1800 MHz (Africa/Europe/Australia/Asia)
1900 MHz (USA/Canada/South America)
To successfully roam onto a network your device must support the corresponding frequency band. Phones are generally available in dual-band (900+1800 or 850+1900), tri-band (any combination of the above), or quad-band with support for all of the above frequencies.
To find which networks and bands are available in which countries, you can use the GSM coverage maps found here or to view them on your mobile device, open your browser and navigate to http://gsmworld.mobi/roaming.
