How much does roaming cost per day for UK travellers?+
UK roaming costs vary by network, plan and destination. On pay monthly plans without Europe roaming, EE charges £2.72 a day in the EU and Vodafone charges £2.75 a day in Europe. Three's Go Roam in Europe costs £2.75 a day for customers who joined from 18 December 2025. O2 includes Europe roaming on its phone plans. Where you pay a daily fee, the cost grows with every day of your trip.
Is it cheaper to buy a local SIM or use roaming?+
For most UK holiday destinations, a HelloRoam eSIM is cheaper than activating roaming through EE, Vodafone, O2, or Three. Buying a local SIM at a foreign shop works too, but you need to find one on arrival, which is no fun after a long-haul flight landing at JFK or Bangkok. An eSIM installs before you leave home and activates the moment you land. You know the total cost upfront, with no daily charge stacking up while you are away.
How do I avoid roaming charges when travelling abroad?+
To avoid roaming charges, turn off data roaming on your home SIM and use a prepaid eSIM for your data. On iPhone, go to Settings, then Mobile Service, tap your UK line and switch off Data Roaming. On Android, find the data roaming setting in Settings, then Connections, then Mobile Networks. Buy your HelloRoam international data plan before you leave, set it as your data line, and keep your UK SIM active only for calls and texts. You pay one prepaid HelloRoam price for data on a local network, so your data adds nothing to your EE, Three or Vodafone bill.
Is eSIM cheaper than roaming?+
Yes, for most trips an eSIM is cheaper than roaming with a UK network. In the USA, EE charges £6 a day, and Vodafone and Three charge £8 a day on newer plans. O2 includes Europe roaming on its phone plans, but its Travel Bolt On costs £7 a day outside Europe. A HelloRoam eSIM gives you a flat upfront price, no daily fees and no risk of a surprise bill when you get back.
Is eSIM worth it for a two-week holiday in Europe?+
A fortnight in Europe is exactly the kind of trip where an eSIM saves real money. With EE or Vodafone roaming in Spain, France, or Italy, you pay a daily fee for every day of those two weeks. A HelloRoam 10GB eSIM covers the same fortnight for a flat one-off fee on local networks. Keep your UK number on your primary SIM for calls and let the eSIM handle your data for the trip.
What is better, roaming or eSIM? eSIM vs sim vs roaming explained.+
eSIM beats carrier roaming on most trips because costs are lower and there are no surprise bills when you get home. With carrier roaming, EE or Vodafone charge you to borrow a foreign network at a markup. With a HelloRoam eSIM, you use a local partner network for one prepaid price across 185+ countries, with plans from £0.77. eSIM vs SIM vs roaming: an eSIM usually costs least on a short trip, a local SIM card can work out cheaper if you stay in one country for months, and carrier roaming tends to cost the most. On a short trip, an eSIM also means no card to find on arrival.
How much does international roaming cost per day?+
International roaming from a UK network is charged by the day, and the rate depends on where you go. EE charges £6 a day in the USA, Canada, Australia, New Zealand and Mexico, £8 a day in places such as Japan and Hong Kong, and £16 a day in its Zone 4, which includes the Maldives and Nepal. The O2 Travel Bolt On costs £7 a day outside Europe. A week outside your network's included zone means seven daily charges before any extra fees.
Can I use an eSIM on a cruise ship?+
An eSIM works when your ship docks at port, connecting to a local network onshore, and the network type depends on each port. It does not work at sea, where only satellite connections are available. HelloRoam covers 185+ countries, so your eSIM connects at each port stop on a Mediterranean cruise that your plan covers, whether you are docking in Barcelona, Valletta, Dubrovnik or Athens. Cruise ship satellite Wi-Fi is often sold per device and per day, so a shore-side eSIM is a useful addition for port days.
Do I need Wi-Fi to set up my eSIM before travelling?+
You need Wi-Fi or mobile data to download your eSIM profile the first time. Install it at home on your broadband before you head to Heathrow, Gatwick, Stansted, or Manchester. Once installed, your eSIM activates automatically when you land at your destination with no airport Wi-Fi required. Get it sorted before you leave and it is one less thing to think about at the departure gate.
Does eSIM use more battery than roaming?+
An eSIM does not drain more battery than roaming. Carrier roaming can actually use more power because your handset searches for an EE or Vodafone partner network abroad. An eSIM connects your handset to a local partner network, so it has less hunting to do. Both options use similar power during a normal day of sightseeing or navigating on Google Maps.
Are eSIMs good for international travel from the UK?+
eSIMs are well suited for international travel from the UK. You install a HelloRoam plan before your flight using your home broadband, your UK number stays active on EE, Vodafone, O2 or Three for calls and texts, and the eSIM handles your mobile data abroad for one prepaid price. No daily fee, no shock on your next bill, and no hunting for a SIM shop when you land.
How much does an eSIM cost compared to UK carrier roaming?+
HelloRoam eSIM plans for international travel start from £0.77. Fixed data plans come in sizes that vary by destination, and some destinations also have unlimited plans priced by the day, with fair-use terms. Compare that with EE's £2.72 a day in Spain or Portugal on pay monthly plans without Europe roaming, or Vodafone's £8 a day in Turkey on newer plans, while O2 includes Europe roaming on its phone plans. On a week's holiday in Spain, Turkey or Portugal, daily fees keep adding up, while a HelloRoam plan is one upfront price.
