What is Mobile Broadband?

Put simply, mobile broadband is a way to access the internet wherever you are. Mobile broadband uses mobile networks (3G or 4G networks) to send data over the air - enabling you to browse anywhere you have a mobile signal.

The days of fixed line broadband connections could be finished thanks to the advent of mobile broadband.  Never again do you have to plug in to the wall to connect to your favourite social network. All you need to do is plug in your mobile broadband dongle or connect to your MiFi (Mobile WiFi) hotspot.

Currently Three offer mobile broadband devices which utilise 3G and 4G mobile networks, which can send a huge amount of data over-the-air and enables you to stream video, download files and browse the internet at superfast speeds.

What are the advantages of Mobile Broadband?

  • Access the internet anywhere

Mobile broadband works anywhere you have a mobile signal giving you ultimate flexibility. Whereas, a fixed broadband connection only works as far as your WiFi connection will reach - and that's not very far!

  • No need for a landline

One of the major downsides of a fixed broadband connection is you need to have a landline phone. Many people no longer require a landline - especially students - and the good news is that you don't need a landline phone to enjoy mobile broadband.

  • Great Value

Mobile broadband connections offer great value with Three plans starting from just £9 a month. The fact that you don't need a landline keeps the cost significantly lower than fixed broadband connections.

What are 3G & 4G Dongles?

In order to connect to your laptop or desktop PC to mobile broadband over 3G or 4G you need a mobile broadband dongle. Mobile broadband dongles, or Internet dongles as they are sometimes known, are small and discreet and plug in to your USB ports with no installation required. 

What is MiFi (Mobile WiFi)?

Some devices don't support standard mobile broadband dongles. However, the operators have come up with a clever solution called MiFi (or Mobile WiFi). Essentially, you get a dongle which creates a personal WiFi hotspot using your mobile broadband connection.

That means you can access it wirelessly and connect almost any internet enabled device. It also means you can share a single 3G or 4G connection with multiple WiFi devices at the same time, including your tablet, desktop PC or games console.

What is the difference between 3G and 4G Mobile Broadband?

3G mobile broadband, which stands for the third generation of mobile technology, offers download speeds up to 100 Mbps and maximum upload speeds of 5 Mbps - which enables users to stream videos, browse the web and video call on the move. Three's Ultrafast 3G network offers double the speeds of standard 3G - improving things even further.

4G mobile broadband will be up to 5 times faster than standard 3G enabling you to do things you couldn't do before - such as streaming HD videos. You'll also be able to upload your photos to Facebook quicker and play online games more smoothly. And the best news of all is Three offers 4G at no extra cost. Three has a range of 4G dongles and 4G Ready MiFi devices available from just £8 a month.

Does Three offer unlimited mobile broadband?

Unlimited mobile broadband is now available on Three and is available with the Huawei HomeFi, Huawei B535. Huawei AI Cube, or the Huawei Mobile WiFi dongle.

Can i get a mobile broadband SIM Card on its own?

Absolutely, Three offer a range of SIM Only plans for mobile broadband devices. They are known as data only SIMs and come bundled with an included data allowance per month. Simply pop one into your existing dongle or MiFi device and away you go!
