What is Mobile Broadband?

Put simply, mobile broadband is a way to access the internet wherever you are. Mobile broadband uses mobile networks (3G , 4G or 5G 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 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 is 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 do not 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 do not need a landline keeps the cost significantly lower than fixed broadband connections.

How fast is Three Mobile Broadband?

Average download speeds on Three mobile broadband are around 22.4Mbps, while upload speeds are around 8.2Mbps. That's according to data from OpenSignal's Mobile Network Expierence Report from April 2020, and those speeds are fast enough to stream full HD videos on Netflix

However, coverage varies significantly from place to place, so it is always best to check coverage in your area first.

What is the difference between dongles and Mobile WiFi (MiFI)?

A dongle plugs into the USB on a laptop or desktop PC to provide internet over mobile broadband. Generally, they only provide internet to the device they are plugged into and are small, discreet and require no installation.

Mobile WiFi (or MiFi) are battery-powered devices that can share a single mobile connection with multiple devices over WiFi.  That means you can access it wirelessly and connect almost any internet enabled device. It also means you can share a single 3G, 4G or 5G connection with multiple WiFi devices at the same time, including your tablet, desktop PC or games console.

Why Choose Three Mobile Broadband?

There are several reasons to choose Three Mobile Broadband:

  • Go Roam - Use your Three mobile broadband abroad in 71 Go Roam destinations at no extra cost
  • 4G at no extra cost - Enjoy superfast speeds on all Three Pay Monthly and PAYG mobile broadband plans

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 could not do before - such as streaming HD videos. You will 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 £9 a month.

Does Three offer unlimited mobile broadband?

Unlimited mobile broadband is now available on Three and is available with the 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!
