Nothing brings on the post-holiday blues faster than a huge phone bill incurred by your device secretly racking up charges while you sipped banana daiquiris.
To prevent a shock raid on your bank account by your phone provider read on for our top tips on using your phone abroad on the cheap.
We reveal the flight mode mistake travellers on planes and cruise ships make, why you should always turn voicemail off, the best network providers for globe-trotters and more.
POST-BREXIT ROAMING CHARGES
Prior to Brexit, the EU Roaming Regulation meant using your existing call, text and data allowances when travelling around Europe incurred no additional costs.
But this guarantee dissolved after Britain left the European Union in 2021.
While many networks – including O2 – continue to offer free roaming in Europe, three of the major providers, Three, Vodafone and EE, quickly re-introduced charges.
According to Clare Casalis, Senior Utilities Analyst at MoneySavingExpert, Three is the most reasonable of the three, charging its contracted customers £2 a day, and also offering multi-day passes, ranging from £5 for three days to £24 for a fortnight.
Meanwhile, EE charges £2.47 a day for those on contract, or £2.50 a day for its pay-as-you-go customers, and Vodafone customers can expect to pay £2.42 a day, £12 for eight days or £17 for 15 days.

Further afield, bills can rack up even more, as international roaming can cost ‘up to £15 a day’.
But it’s cruisers who have to ‘be extra careful’, says Clare.
‘Your phone may connect to a “maritime” network or a neighbouring country, which may be outside your roaming allowance,’ she says. ‘Therefore, it’s probably best to make use of any free Wi-Fi or restrict use of your phone to when you’re back on dry land – and always check the network your phone connects to.’
Clare’s advice, if you don’t want to incur any of these extra charges, is to switch off roaming completely, via your phone’s settings.
And remember, flight mode, which blocks digital data services, can be used in conjunction with Wi-Fi, so you can’t make calls but you can stream movies without ending up bankrupt.
Clare recommends downloading all your important documents – including boarding passes – using Wi-Fi before you travel
| PROVIDER | ADD-ONS FOR INTERNATIONAL ROAMING |
|---|---|
| EE | EE charges between £5 and £15 a day (£25 or £37.50 for 7 days) depending on the destination. |
| O2 | O2 offers O2 Travel, giving you unlimited data, minutes and texts for an extra £6/day. |
| Three | Three charges £5 or £7 a day (depending on the destination) to use your UK allowance in over 100 Go Roam destinations, including the USA and New Zealand. Alternatively, you can get a Data Passport for £5 which gives you unlimited data in 89 countries. |
| Vodafone | Vodafone offers Roam Further – use your UK allowance in 105 destinations for an extra £7.39 a day. |
| Lebara | You can use your UK allowance for free in India and China (as well as Europe). To make calls, use data or send a text while outside the EU roaming countries and India, you can buy an 8 or 15-day roaming add-on for your selected country. |
| Sky | For Australia, Canada, New Zealand, South Africa, Turkey, USA and the UAE, you can use your UK plan for a £2/day fee. You don’t need to do anything to get this service. Find out more about the Roaming Passport Plus pass here. |
| Voxi | You can get an eight-day Global Roaming Extra add-on to use in 73 countries, including Australia, Canada, Egypt, Mexico, New Zealand, South Africa, Thailand and the USA. It costs £15 for 8 days (100 minutes, 100 texts, 2GB data) or £25 for 15 days (200 minutes, 200 texts, 4GB data). |

VOICEMAIL WOES
‘Outrageously,’ says Clare, ‘if you’re outside Europe, you can be charged simply for someone leaving you an answerphone message – even if you never hear it.
‘It all depends on the network you’re on and the country you’re in.
‘As an example, if you’re with EE, it can cost as much as £2.34 a minute to receive a voicemail, and a further £2.34 a minute to listen to it.
‘So picking up a one-minute message could cost you almost a fiver.’
To avoid this unnecessary expense, Clare recommends checking whether your network charges for the country you’re headed to.
Then, she says, ‘simply turn off your voicemail to stop people being able to leave you a message in the first place’.
Cruisers have to ‘be extra careful’, says Clare, because ‘your phone may connect to a “maritime” network or a neighbouring country, which may be outside your roaming allowance’
The money guru continues: ‘Each network has different instructions on how to do this, though you normally have to make a call, so try to make sure you do it before you travel – and certainly before you leave the UK.
‘If you want to be extra safe, you can set your own spending cap, which means you won’t be able to exceed that limit, so you can avoid any unexpected bills. This will cover costs incurred by data roaming, calls and texts.
‘You can do this via your network’s website or app, though if in doubt just call it and ask.’
PROVIDER PROTECTION
‘Don’t get caught out by your network’s “fair use” policy when roaming,’ warns Clare. ‘Even if your provider allows you to use your allowance in Europe, most will still limit the amount you can actually use while abroad through a fair use policy.’
This means you could find yourself running out of data quicker than usual, and having to pay more.
WONDERFUL WI-FI
Clare recommends using Wi-Fi where possible, even for phone calls.
She explains: ‘If you’ve got a smartphone and free internet access, download an “internet-to-phone” calling app such as Skype, WhatsApp or Facebook Messenger before you go, or use Apple’s FaceTime.
‘Providing the person you’re calling also has the service, you just need to find a free Wi-Fi spot to call for free.’
You could also use this free internet – usually available in your hotel or restaurants and cafes – to download entertainment, like music and films, but Clare suggests doing this before you jet off, along with downloading boarding passes and maps.
JOYS OF THE ESIM
For travellers tied down to a phone contract, Clare recommends an eSim. ‘With an eSim, you can choose the amount of data and length of time you need it for’
| ESIM PROVIDER | USA | INDIA |
|---|---|---|
| Airalo | $26 (£20) for 10 GB for 30 days | $25 (£20) for 10 GB for 30 days |
| Easysim | £16 for 10 GB for 30 days | £79 for 10 GB for 30 days |
| GoMoWorld | €19.99 (£17) for 30GB for 30 days | €19.99 (£17) for 20GB for 30 days |
| Holafly | £59 for unlimited data for 30 days (1) | £67 for unlimited data for 30 days (1) |
| Nomad | £14.50 for 10 GB for 30 days | £21 for 10 GB for 30 days |
| uSwitch | £11 for 10 GB for 30 days | £56 for 10 GB for 30 days |

Clare says frequent travellers to Europe might want to consider switching to a smaller provider that ‘piggybacks’ on one of the four UK mobile networks (EE, Three, O2 and Vodafone). Why? ‘Many of these don’t charge for EU roaming, but you’ll get the same network coverage,’ says Clare, who also notes that international eSims are a less permanent option.
These virtual Sim cards allow users to connect to a local network, alongside a UK physical Sim, meaning you don’t need to be tied down to a contract.
Clare adds: ‘With an eSim, you can choose the amount of data and length of time you need it for – it often works out much cheaper than paying your UK provider’s roaming fees.’
