Beginners Guide: what is mobile broadband?

What is mobile broadband?

Mobile broadband is high speed internet access via mobile networks.

Mobile internet technology allows you to do all the things you usually use your broadband connection for without needing a fixed-line telephone connection.

This means you can get online on the move (on public transport, for example) or away from home (perhaps on holiday or at uni). Send email, visit websites – even watch streaming TV clips and download files – it's all possible.

How does mobile broadband work?

Mobile broadband uses the same signal that serves mobile phones. But you’re only using it for internet access, not voice calls.

What do I need to use mobile broadband?

Mobile broadband can be accessed using either a small portable USB modem (often called a dongle or stick), a built-in device on some laptops and tablets, or a mobile Wi-Fi (aka MiFi) unit.

USB dongles require a compatible desktop or laptop computer. Mobile Wi-Fi will work with any device that supports wireless networking.

Can I use mobile broadband abroad?

Some mobile internet tariffs have a block on them so it's only possible to use them within the UK (this is common with PAYG deals), but if not you can use them in any country support by your mobile broadband provider. Prices have come down a lot in recent times - especially in Europe where roaming is now free - but it can still be an expensive hobby. See our guide to using mobile broadband abroad for more information, or our useful mobile broadband roaming tool for an overview of the costs worldwide.

Is mobile broadband unlimited?

Mobile broadband is not unlimited. At this time all mobile internet deals have a data usage limit - the more you pay, the higher the cap.

When buying a mobile broadband service it’s important to think about potential usage. Choose a data cap that’s too high and your money is wasted, but go too low and you could be hit with extra fees for exceeding the limit. Our guide to mobile broadband data usage can help point you in the right direction.

What is 3G, 4G and 5G?

3G, 4G, and 5G refer to generations of mobile technology. 3G was first to offer broadband speeds over a mobile network. 4G is the following iteration of mobile networks which provides vastly improved connection speeds. 5G is the very latest version of mobile technology which can deliver even faster speeds than 4G.

Should I get 3G, 4G or 5G mobile broadband?

If you’re buying a new mobile broadband service it’s best to go with a 4G device over 3G as it’s significantly faster. 5G is also worth considering, but coverage is currently limited so you'll only get a signal in major towns and cities.

Our guides to 3G dongles and 4G mobile internet have further information if you’d like to learn more.

Can mobile broadband be used instead of home broadband?

Mobile broadband - especially 4G and 5G - is fast enough to be a viable alternative to fixed line home internet. But for many people it will not be the best option, largely due to the relatively low data limits. Unlimited home broadband is far better for heavy users and shared homes.

Do I need mobile internet?

Mobile internet is a great option for people who travel a lot, or have a long commute to work and need to make the best use of their time. You can get online anywhere with good coverage, making it great for business people. Smartphones are great, but why fiddle around on a small screen when you can work on your laptop?

Mobile broadband is also popular amongst subscribers who don't have a fixed residence, such as students. This is because you can pay for one service but use it at home, in digs, in the library – even in lectures. Also, with lots of pay-as-you-go (PAYG) options, you don't have to sign your life away. Thanks to mobile Wi-Fi, you can even share your mobile broadband connection!

Are there any downsides to mobile broadband?

There are currently two main possible downsides to mobile broadband: stability/coverage and usage allowances.

You need to realise that, despite its popularity, mobile broadband is still a little behind home broadband. The technology is improving all the time but right now it isn't always a smooth ride. If you require a guaranteed stable, fast connection, you're probably best advised to look for a fixed-line broadband solution – although mobile broadband is a brilliant back up even then.

Speed can also be an issue for some. While advertised 3G speeds currently range to a max of 21Mb, the reality for most people is something in the region of 5-10Mb. While this should be fine for the basics, such as web surfing and emailing, you may struggle with tasks such a big downloads (where download limits may also be a factor), streaming video and audio (such as using Spotify or the BBC iPlayer) or gaming.

4G and 5G are both significantly faster, however coverage can be a problem, especially for 5G.

Can I cancel my mobile broadband account?

Every mobile broadband provider is different, so it's vital you check the terms and conditions of a contract before committing.

Some mobile broadband operators offer a 'cooling off' period of around two weeks. If you’re unhappy with the level of service, or the network performance, you should be able to return your dongle and cancel your contract without having to pay extra.

If the internet service provider you've chosen doesn't offer this, remember that if you buy online you are covered by the UK's distance selling regulations. This means you can return the product within seven working days if it does not meet your expectations.

What happens if I cancel a mobile broadband contract early?

If you want to cancel your mobile broadband before the term is up, you may be responsible for paying the remaining fee for your subscription. This may be waived in exceptional circumstances (such as moving location), but providers deal with these on a case-by-case basis. Unfortunately, stopping payments altogether is very rare.

If you're completely new to mobile broadband, there's always the option of going pay-as-you-go initially to try the service, before you commit to a lengthy contract.
