Mobile Broadband & Wi-fi

Find free UK hotspots or get cheap 3G & 4G access

If you want web access on the go, there are thousands of free, legal wi-fi hotspots around the UK. And if that's not enough, there are mobile broadband packages giving you wider access without costing a fortune.

This is a detailed guide to getting internet access while you're out and about, including info on wireless hotspots and the cheapest mobile broadband packages.

Wi-fi or mobile broadband?

There are two ways to get internet access when you're out and about: via wi-fi hotspots or mobile broadband.

  • Wi-fi hotspots

    These allow your mobile, tablet or laptop to connect to a broadband signal through the air, without wires, if you're within range of the access point. You can sometimes connect for free at cafes, bars and restaurants. It's the same principle that applies when you're at home - you're just tapping into a much bigger signal this way.

    There are 100s of free hotspots, so if you've free wi-fi access at work and in nearby cafes for lunch, don't pay for it.

  • Mobile broadband

    This uses your network provider's 3G or 4G mobile signal to connect you. It requires one of two pieces of hardware - a dongle or Sim. A dongle is a wireless adapter that allows you access to wi-fi on your laptop, while a Sim allows you access to wi-fi on your smartphone or tablet.

    Most mobile phone contracts offer a data allowance each month, meaning you can use your mobile to browse the web when you're out and about.

    But if you want to use your tablet or laptop it might be worth getting a separate mobile broadband deal - there are plenty of cheap ones around to choose from. Remember free's always best, so use free wi-fi hotspots when you can.

Best option for all: get FREE wi-fi

Wi-fi allows your mobile phone, tablet or laptop to send and receive data, without being tied to a specific router.

You can access free wi-fi at hundreds of free hotspots around the UK - in shopping malls, cafes and restaurants. Your employer may also have wi-fi you can use for free when you're at work.

What is a wi-fi hotspot?

A wi-fi hotspot is simply an area in which you can get a wireless network signal. There are 1,000s spanning the country, many of which are free.

Hotspots are great because you won't eat into your mobile broadband/phone data limit. In any built-up area, it's unlikely you'll be far from free wireless access.

Almost all new computers and laptops have wi-fi capability built-in. If they don't, most can be upgraded with a USB wireless network adaptor (which cost as little as £5 - find one using the MegaShopBot).

Warning! Do check it's free wireless and you're not just using someone's private connection, as it's illegal to hijack someone's wi-fi without permission.

Where can I find one?

There are several ways you can access free wi-fi when you're out and about.

Sign up to automatically access wi-fi hotspots

Wi-fi hotspots are becoming more common - and some of them are free to use. O2 hosts thousands of wi-fi hotspots around the UK. You DON'T need to be an O2 customer to access them. O2 wi-fi is free and available to use in over 10,000 locations around the UK including many leading high street retailers

Considering how large the network is, it's well worth registering in advance. Then set up your phone to automatically connect to the wi-fi and it'll pick up the signal when you're in an O2 area. Or use the O2 hotspot finder to find a free hotspot near you.

Sky's also got a network called The Cloud (see below for more info). If you're a Sky customer you can use it for free for as long and as much you like, while other people can use it for free for the first hour. You'll have to register to access it though.

If you're in town, you can find free, no-password-necessary wireless access at the high street shops and eateries above.

Though the wi-fi is free, you may have to buy something or sit and eat in the restaurants/pubs. Also, some may only give you access for a limited time.

While a lot of the high street chains use the more established wi-fi hotspots, they may also have their own service you can use. To access it you might have to sign up or get a password from one of the staff. How long it's free depends on what deal the shop or restaurant is offering.

Special customer-only deals

Depending on which company provides your home broadband and/or mobile phone service, you may be able to get free access to wi-fi hotspots around the UK. Here's some more info:

BT or EE/Orange/T-Mobile customer? Get free BT Wi-Fi

Anyone with BT broadband or with an EE/T-Mobile/Orange mobile can get free, unlimited internet via five million BT Wi-fi hotspots (depending on your tariff). BT Wi-fi and broadband customers can also access the Fon network, which works by sharing a small amount of your own broadband connection with other BT users who in the area. In return, you're able to access their connections if you're nearby.

To sign up you'll need your BT internet email and account password. EE customers (incl Orange and T-Mobile customers) have to get the EE app and the free wi-fi hotspots service has to be included in their plan to get BT Openzone wi-fi. If they don’t have the app, they can log in instead.

Check BT wi-fi hotspot coverage with the BT wi-fi directory.

Sky customer? Get free access to The Cloud

One of the fastest growing wi-fi networks, The Cloud has thousands of hotspots all over the UK, including at 56 London Overground stations. The Cloud is owned by BSkyB, so Sky Broadband Unlimited, Sky Connect or Sky Fibre customers can get free, unlimited access to all hotspots (see Sky's website). The Cloud also has a deal with Nintendo to provide free wireless access to all 3DS users.

Most Cloud hotspots are free to use, and you'll always be told when you log on if it isn't. Some hotspots will give you 15 minutes free, while others may charge from the moment you log on (for these ones you'll need to set up an account).

If you download The Cloud's hotspot finder app, you'll be able to access the hotspot location map even when not online, as it stores a version of the map on your device.

Virgin Media, EE/Orange/T-Mobile, Vodafone, O2 or Three customer? Get free wi-fi on the underground

In the run-up to the 2012 Olympics, Transport for London introduced wi-fi at a number of London Underground stations. It's now available at 150 stations across the network.

The provider is Virgin Media, which means that if you've got broadband, phone, TV or a mobile plan (incl pay-as-you-go users) with Virgin, you can access it free. But wi-fi access is also free for EE (incl Orange and T-Mobile), Vodafone, O2 and Three customers.

To sign up, Virgin customers will need their Virgin Media username and password. Other eligible customers need to register with their network first to get access - see TfL's Station wi-fi page for full info.

If you're not a customer with any of these providers, you can buy a day, week, or month pass to get access. See the Virgin Media website for details.

Plan your route before you go

If you've web access and a few spare minutes at home, there's a host of sites which list wireless hotspots, and a few tools to help you find them. One of the most popular (and up-to-date), is JiWire, which allows you to type in a postcode or place name and search for free local spots amongst the 145,000 or so available on its database. It's iOS and Android apps have decent feedback.

It's also worth checking My Hotspots, Free Hotspot, and Boingo for finesse. Where possible, be sure to limit your search to hotspots listed as 'only free'.

Warning! Beware cyber hacking and thieves. While the existence of wireless networks accessible to everybody is a great thing, be wary of cyber hacking and thieves.

Don't enter any secure info when using public wi-fi spots, as there's a risk it can be intercepted by others on the network and used for identity theft.

Also, it's easy to get lost in the web. The presence of a few people focused on their laptops is a big draw for pickpockets and bag thieves, so keep an eye on your stuff at all times.

Browsing on your mobile? Know the costs

If you can't get free wi-fi on the go, the next best option is using your mobile's 3G or 4G signal for web access as long as you're happy browsing the web on your phone.

Most major networks such as EE, Vodafone, O2 and Three have extensive signal coverage across the UK. So if your tariff's with any of these, and you're constantly travelling, you can use your mobile for browsing or sending emails in most areas.

Many mobile phone deals allow at least 1GB of data to use each month - equating to sending 1 million emails a month or visiting 10,000 simple sites. This means that many people will have enough data allowance from their phone contract without having to worry about paying extra. For more info on finding the right tariff for you, see our Cheap Mobiles, iPhone and Samsung guides.

But be wary of going over your data allowance. This is essentially the maximum web usage you can get through each month. Once you go over your tariff's limit, costs can mount up. For example, outside the monthly data amount, Vodafone charges £6.50 for every 250MB used and O2 charges £1 per day (up to a maximum of 50MB/day). Roughly, 250MB will allow you to send 500 emails with photos attached or visit 2,500 simple sites such as Twitter.

With some tariffs, networks send you alerts once you've used 80% and 90% of your allowance. If yours doesn't, ask your provider if you can start receiving them.

If you're a heavy user it could be worth considering a deal offering a bigger data allowance. Many mobile phone providers also offer deals with high data usage for an added cost.

Mobile broadband: best buys

If you'd rather use your tablet or laptop instead of your mobile and you can't get free wi-fi, mobile broadband is an option.

It allows you to get online wherever there's a mobile signal by connecting your device to the internet anywhere via a USB dongle (for computers), or separate Sim (for tablets or any other 3G-compatible device).

It's generally not as fast as home broadband, so not really suitable for streaming films, but it's fine for emails and general surfing. For most, coverage is the most important factor when choosing a mobile broadband package.

Most network providers now offer mobile broadband tariffs, but service varies dramatically. We've picked out best buys below with a focus on data allowance, including mobile broadband contracts and pay-as-you-go deals and dongles - but remember, only pay this way if free wi-fi spots aren't available.

There are a few crucial things to consider when deciding on a mobile broadband package:

Find the best deal for you

Check coverage

Watch out for download limits

Remember speeds will be slower than home broadband

You may pay upfront costs

Using it abroad can cost LARGE!

Top plan with a dongle

If you're a heavy user, it can be pricey using a dongle. If possible, ask to try out a friend's dongle at home before investing in your own, as speeds and coverage can differ widely too, even in small areas. These are the best we found.


5GB monthly data allowance for £15.99/month


If you're a fairly heavy user and tend to watch films, download music, send emails and browse the web lots each month, this Three* deal could be your best bet. Be careful not to go crazy with it though, as the allowance, though generous, is still limited.

It's £15.99/mth for a hefty 5GB/mth on a 24-month contract, or you can get it on a 30-day rolling contract for the same monthly price but with a £4.99 upfront payment. The price includes the USB 3G dongle (there's a 4G version* available for a £35 upfront fee).

Three estimates that 5GB will be enough to surf the web for 50 hours and download 160, four-minute songs each month. To get it, click the link above and scroll down for the 5GB dongle. There's also a 1GB plan available for £7.87/mth - although an allowance this size wouldn't go far on a laptop - or a 15GB plan for £19.99/mth.

Three claims to have 97% coverage for calls, texts and mobile internet - see its coverage checker to see if it's available near you.

  • Monthly cost: £15.99/month

Top plan for browsing on your smartphone

Unlimited minutes, texts and 3GB of data for £15/mth

Virgin Mobile*

Although not geared specifically towards mobile internet, this Sim-only tariff is our top pick for smartphone users and comes with a decent amount of data. Virgin Mobile's* £15/mth tariff gives unlimited minutes, unlimited texts and 3GB of data.

It's £15/mth on a 12-month contract, or if you're a Virgin Media customer you can get it on a 30-day rolling contract for the same price (£20/mth for non-Virgin customers).

The 3GB of data is enough for medium to heavy users, and means you'll be able to download around 180 songs and use the web for 90 hours. If you exceed this allowance you'll be moved onto Virgin's daily rate for data, which is £1 for unlimited usage.

It's available on standard, micro and nano Sims. There's a 99p delivery charge for the Sim, though this is free if you're already a Virgin customer.

  • Monthly cost: £15
  • Data allowance: 3GB
  • Additional usage costs: £1/day (unlimited)
  • Contract length: 12 months
  • Modem and connection fee: N/A

Tips to minimise data usage

As mobile broadband is a lot more expensive than home broadband, you should try to minimise your data usage wherever possible. It's also worth installing a free bandwidth monitor like tbbMeter, Rokario or Netmeter to be doubly sure you don't go over the limit. Here are a few tricks:

Turn off automatic updates

This is probably the most important way to save your precious download allowance, and the easiest way to get caught out. Many programs, as well as operating systems themselves, routinely check for available updates and download them.

Downloads can run to hundreds of megabytes; not ideal if that's all you have to play with. Turn them back on when you have the bandwidth though, or you might leave security holes open on your machine.

Turn off images when you use the web

If you're content to do without pictures when browsing (even just temporarily) then it's usually easy to disable them. In Internet Explorer, click Tools, then the 'advanced' tab, and scroll down the list to Multimedia.

In that section, uncheck the 'show pictures' box and while you're there, the 'Play animations in webpages' box. The procedure's similar in all browsers.

Change your email settings

If you manage your emails with a program such as Outlook or Thunderbird, you may save data by signing up to a web-based service such as Yahoo! Mail or Gmail.

Redirect some emails to the web-based account, and if a friend decides to send you party pictures when you're away, you can choose not to download them till you get back. (See Martin's blog for a data roaming horror story.)

You could also change your settings to download headers only, or else set up filters which cut out less important or larger emails. How to do so will depend on the software you favour, but most offer detailed guides.

Get rid of ad/spyware

Adware and spyware programs, which usually manage to sneak onto your machine without you noticing, can use up your valuable allowance by talking to their leaders out in cyberspace.

They can also leave your computer prone to attack by all manner of other nasties, so it's worth downloading a free tool to get rid of them (on another connection if possible). Find one in the Free Antivirus guide.
