Get the low-down on the jargon


Smartphones have advanced mobile operating systems that combine some of the features of a personal computer with a digital camera and video camera, Wi-Fi connectivity, GPS navigation, the ability to run apps and games, plus much more.


You might have the option of adding additional features to your mobile plan depending on the provider. Some will allow you to pay extra for features such as music streaming for an additional cost.

Operating systems

Your phone's operating system is the software that manages its basic functions and features. For many smartphones this includes Bluetooth connection, GPS navigation, and the ability to connect to Wi-Fi and mobile networks. The operating system also allows you to access and interact with applications on the device.

Plan type

When deciding on a plan, you can usually choose from prepaid or postpaid. Prepaid plans allow you to purchase credit upfront, while postpaid plans bill you for your previous month's usage.

Data allowance

You use data to access the Internet, download emails, stream music and videos, run some games and applications, and get directions. It's important to strike the right balance with your data allowance or you may end up paying more than you need to each month for unused data or excess data rates.


New songs from your favourite bands, binge-worthy TV shows, and cult movies. With a suitable data allowance, you may be able to enjoy a world of entertainment without clogging up your hard drive, thanks to apps that allow you to stream music and video from your smartphone.
