If you're not careful, using the web abroad could rack up a bill of £100s or even £1,000s. Surfing the net can cost as much as 46p/MB in EU countries, and up to £8/MB around the rest of the world.

The most sensible plan is to keep your phone turned off. But if this isn't possible, there are ways to cut costs. This guide shows you how to get the cheapest data access wherever you are.

Quick tips before you go

If you do nothing else before you go, these quick tips should help to keep costs to a minimum:

How much does data cost?

Using your mobile to access the internet abroad (data roaming) costs a lot more than it does within the UK. Mobile phone networks charge for internet access by megabyte (MB) of data downloaded.

To give you an idea on how much data you'll use, try the Vodafone data usage calculator. As a rough rule of thumb, 1MB will let you send about 20 emails without attachments.

The amount you'll be charged depends on your mobile phone network and location.

You'll be charged around 46p/MB in the EU, and up to £8/MB further afield. As an example, Three charges a whopping £6/MB in Canada. As a 30min TV programme is 500MB, that could easily add up to £3,000.

Get it wrong, and it could cost you £1,000s

If you don't take precautions before travelling, you could arrive home to a nasty bill shock.

Forumite shockedandstunned really suffered:

Just got my stepson's phone bill and it's over £4,500. He's been to Turkey for 2 weeks and left data roaming on/been on the internet, as it's all data charges. - shockedandstunned - Aug 2012

Use free wi-fi hotspots abroad

If you'll only occasionally need to access the web while travelling, and your laptop, mobile or tablet has built-in wi-fi, using wireless hotspots is the cheapest way to get online.

How to find a free wi-fi hotspot

  1. Be prepared. Set aside a few minutes at home before you go, ask your hotel and check the host of sites that list wireless hotspots around the world.

  2. Local hotspots. JiWire allows you to type in a place name and search for local spots among the 800,000+ on its database. It's worth checking Free Hotspot and Hotspot Locations too.

  3. Try Google Maps. You can also use Google Maps to find places which offer free wireless access. To find them, type in the name of the area you're going to, click on the marker, then "Search nearby" and type in "free wi-fi". The map will show all locations with free wi-fi. Alternatively, type into the search box on the Google Maps home page: Free wi-fi loc: PLACE NAME, eg, Free wi-fi loc: Calas de Mallorca.

Boost wireless potential abroad by sharing your wi-fi at home

WARNING! Beware cyber hacking and thieves

Mobile data roaming add-ons

EU regulations mean the price of using the web abroad is falling, but it's possible to cut the costs further. If you're a monthly contract customer and you're only likely to use a few megabytes of data, get an overseas data bundle from your network. Below are the major mobile providers' offerings.

WARNING! Opting out of the €50 EU cut-off limit

Data roaming add-ons for within the EU

If you're with Orange*, there’s a range of data bundles. For short trips within Europe, the cheapest option is Orange’s daily 20MB for £1. This should be enough for you to browse the web for about hour, or send 20 emails with attachments, in one day.

You’ll only be charged for the add-on each day you use data. Any unused data in a day won’t be carried over. If you need more data or are going away for longer however, Orange does offer other data deals, including 100MB/day for £3 or 150MB data for £50, which can be used over a month.

Switch Sim for cheaper rates

If you're a frequent traveller, a heavy data user or going away for a bit longer than usual, you may be better off getting a cheap data Sim deal specifically for the country you're travelling to - especially if your mobile provider's data add-on offering isn't that hot.

It's likely to be the most cost-effective way to get online (if you haven't got free wi-fi access). The per-MB savings here can be huge, as you'll sidestep roaming rates entirely and only pay local costs.

But it can be a fiddly process, and there's no easy solution to finding the best deal. With most Sims, you'll also need an unlocked mobile (or mobile device).

Finding the right Sim

There are three types of Sim card you can buy to help cut your roaming costs while abroad:

  1. PAYG local Sim (bought on arrival). If you regularly visit the same country, the cheapest way to get online (if you don't have wi-fi) is to buy a local Sim when you arrive at your destination. Though this is the very cheapest way, it is a bit of a faff, and you may prefer to have something set up before you go. More info.

  2. Pre-paid local and global Sims. The alternative (which is a lot less hassle) for those who regularly visit one country or go for quite a while, is to buy a local Sim for the country you're visiting before you go, and load it with credit so you don't have to worry about topping up while abroad. If you travel to numerous countries, a global Sim would be more suitable. More info.

PAYG local Sim (bought on arrival)

This growing Wiki Resource has users' recommendations on PAYG overseas data Sim cards, though its accuracy depends on how up-to-date people have kept the info. Use the list on the left-hand side to pick a country, and it'll show you available PAYG data Sim options, where to buy them when you arrive, and how to get connected once you get the Sim.

Alternatively if you're willing to do a little more legwork yourself, Wikipedia lists the mobile networks available in every country.

Once you know which providers operate in the country you're travelling to, it's possible to compare deals on their sites before you go, and buy a PAYG Sim card when you get there.

Pre-paid data Sims

There's a whole load of providers offering pre-paid data Sim deals, so if your mobile provider's data add-on deal doesn't meet your needs, consider getting one of these. The best for you will depend on your usage and the country you are visiting. Here are our top picks:


DataroamBest for light/medium users, 70+ countries from 19p/MB

  • What: Dataroam International Pre-paid SIM Card
  • Upfront cost: £14.99
  • Free credit: $10
  • Cost/MB: from 19p/MB

The Dataroam International Pre-Paid* Sim offers rates from just 19p/MB, and can be used in 70+ countries, including most of Europe and the US. Check the country you're visiting is included in the low rates before buying. More...


RoamlineCheapest upfront cost, 34 countries for 34p/MB

  • What: Roamline SIM Card
  • Upfront cost: €9.95 (£8.38)
  • Free credit: None
  • Cost/MB: from €0.39 (34p)/MB

With Roamline's Global Data Sim you'll pay €9.95 (£8.38) upfront and then get charged €0.39/MB (34p) for data roaming in Europe, the US and Canada. Go outside these areas and you'll pay €0.89/MB (77p).

Unlike the other Sims here, you pay through your credit card at the end of each month, so you don't have to top up before you go. If you use more than €50 on mobile data you will be charged and informed by email in between. More...

Mobile data add-on or Sim card - which is best?

Depending on where you're going and what you'll be doing when you're abroad, it may be worth getting a Sim card deal - especially if your mobile provider's data add-on doesn't offer any real savings.

In the table below, total costs have been calculated including any initial upfront costs and subtracting any free call time offered. As you only have to pay the upfront cost of the Sim once, this could be a better investment if you plan to use it frequently.

Sim card and data add-on deals compared
Upfront cost Free call time (included) Cost - £/MB Total cost
50MB 100MB 500MB
Dataroam £14.99 $10 25p/MB £21.55 £39.99 £139.99

What to do if you receive a BIG bill in error

If you arrive home from holiday to a mammoth mobile bill and you've been charged incorrectly, you should be able to get some money back.

Step 1: Complain to your provider

Contact your provider straight away. Send it a copy of your bill, highlighting the relevant charges and the reasons why you are disputing them.

Below are the contact details of some of the main mobile providers:

Online contact Customer services number
Three Call 333 from your Three phone
O2 Call 202 from your O2 phone
Orange Call 150 from your Orange phone
T-Mobile Call 150 from your T-Mobile phone
Vodafone Call 191 from your Vodafone phone

Step 2: After eight weeks, complain to the Ombudsman

If after eight weeks you've not resolved the problem or are unhappy with your supplier's decision, you can submit your complaint to one of the two independent Alternative Dispute Resolution (ADR) schemes. The schemes are impartial and free.

The two to go to are CISAS or Ombudsman Services: Communications. Use the ADR checker on Ofcom's website to check which one your provider's signed up to.
