What is a mobile network?

Keeping up to date whilst travelling on the bus

What's coming up

In this activity, we will explain two main things about your phone:

  • What data is.
  • What mobile data or mobile internet is.

We'll also talk about what you can do on your mobile data.

Start activity

Smartphones and the internet

Mobile phones can do a lot more than make calls. The newest types of mobile phone are called smartphones because of all their extra features. Most of these features are about going onto the internet to do different things.

Smartphones are like handheld computers that can do just about everything a computer can, but in a slightly different way.

Smartphones can do so much more than just make voice calls these days

Understanding data

Like a computer, a smartphone can display web pages, show photos, get email and even play movies from the internet. All this internet content is sent to your device as data.

How much data you need to use depends on what you are looking at. For example, a page of text needs far less data than a photograph to display, and a photograph needs less data than a movie.

10GB of data can allow you to do many things on the internet

Measuring data

Data is measured in gigabytes (usually referred to by the letters GB).

A home internet plan usually allows you many more gigabytes of data per month than a mobile phone plan.

Wi-Fi and mobile internet in one

A smartphone can use a home Wi-Fi network to get data from the internet, just like a computer. But a smartphone can also get data from the internet via a mobile data network.

Mobile data (mobile internet) is transmitted by the same mobile phone towers used to make voice calls on a mobile phone.

The mobile advantage

A smartphone can stay connected to the internet all the time. As long as the phone has a minimum amount of reception, it can get data in the form of web pages, email, photos and more, using a mobile data network.

In fact, a smartphone can do so much, for many people, its internet and data features are more important than making voice calls.

Well done!

This is the end of the What is a mobile network? activity. You've learned that mobile phones use the mobile phone network to connect to the internet, and that smartphones use the internet to do many different things - even as much as a laptop computer.
