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 an 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 a small portable USB modem (often called a dongle or stick), a mobile Wi-Fi (aka MiFi) hotspot, or by tethering a smartphone. Some laptops and tablets also include built-in support for mobile broadband.
USB dongles only work with a compatible desktop or laptop computer. Mobile Wi-Fi and tethering will work with any device that supports wireless networking.
Can I use mobile broadband abroad?
Some mobile internet tariffs have a block 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 supported by your mobile broadband provider.
It used to be very expensive, but prices have come down a lot in recent times, especially in Europe where roaming is free. 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?
Most mobile broadband deals are not unlimited, though there are a few deals from Three and Vodafone which offer unlimited usage. EE also offers some packages with very high data use limits.
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 the 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 you should make sure that it supports 5G, as 3G is now quite old and significantly slower, and 4G is gradually being supplanted by 5G.
However, 5G coverage is currently limited so you'll only get a signal in major towns and cities. But you will be able to use 4G or 3G when it is not available.
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. 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 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 backup even then.
Speed can also be an issue for some. You'll find that the advertised speeds may not be achieved in practice, especially if you're using 3G. As a result, 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.
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.
