Airalo review: how I beat mobile roaming charges abroad using travel eSIMs

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

Using your phone abroad can quickly get expensive when you rely on your existing phone line.

Fortunately, a simple workaround has emerged in the past few years, enabled by new eSIM technology found in virtually all modern handsets.

For example, Vodafone will charge you £2.42 per day just to use your normal allowance in France. Outside of Europe it can be £5+ per day – Dubai is now £7.39 per day for Vodafone customers for example.

For EU roaming, O2 remains the best UK mobile network

O2 is now the only mobile network of the big four to include free roaming in Europe for all pay monthly customers. It’s one of the reasons I swapped a few years ago (although the signal in London is rubbish ….)

48 countries/territories/areas are included. The full list is on the O2 website here but basically it covers all of the EU and European Economic Area. Switzerland, for example, is included, as is Norway, despite neither being part of the EU.

Calls and texts to UK numbers are also free or charged at the same rate as they would be if you were in the UK. Calls to international numbers are separate – although O2 offers an paid-for ‘International Bolt On’ that reduces the cost of these too.

If you are on a monthly plan, you can use your data in O2’s Eurozone up to a maximum of 25GB (or less, if your plan includes fewer GBs.) Any data usage beyond this will be subject to throttling.

Outside of the four major carriers, you’ll also find free EU roaming on these virtual mobile networks:

  • Asda Mobile (5GB fair use limit, uses Vodafone)
  • GiffGaff (5GB fair use limit, uses O2)
  • iD Mobile (30GB fair use limit, uses Three)
  • Lebara (30GB fair use limit, uses Vodafone)
  • Lycamobile (fair use limit varies, uses EE)
  • Smarty (12GB fair use limit, uses Three)
  • Superdrug Mobile (12GB fair use limit, uses Three)

Finding local eSIMs with Airalo

If you’re travelling beyond the European Union, or you’re with EE, Vodafone, Three or another network, then your best option is purchasing a local SIM card at your destination.

This has been made even easier with the introduction of eSIM across many mobile devices, including from 12th generation iPhones (the 2018 iPhone XR and XS). Samsung was a bit behind the curve and only introduced eSIMs to its 2020 Galaxy S20 phones but too are now standard.

Most handsets from the last 2-5 years come with dual SIM support, either in the form of two SIM card slots or a physical SIM slot and eSIM support.

That means you can now connect to two mobile networks at once – letting you retain your UK number and SIM whilst supplementing it with a local SIM depending on where you’re travelling.

eSIMs make this even easier because you don’t need to wait until you arrive at the airport or faff around with tiny SIM cards. You can simply scan a QR code to add a data plan to your phone.

This has led to a number of third party companies popping up to connect travellers with local SIM cards, including Airalo which is what I use.

Airalo – website here – bills itself as the world’s first eSIM store. It gives you access to 200+ eSIMs globally, including a range of local, regional and global SIM cards.

I have now used Airalo over fifty times and have been very impressed. The process is extremely simple, as demonstrated by this infographic:

How Airalo works

In reality, you do not need even need to install the app. You can also use the web interface.

What I particularly like about Airalo and eSIMs is that I can install my international data plan before I leave the UK. This means I have a seamless data connection once I land at my destination. This is especially useful in case I need to show any documents on my phone but can’t connect to Wi-Fi.

How does Airalo work?

On Monday I am heading to the United States to try out Iberia’s new A321XLR aircraft in business class. This is unfortunately outside of my O2 free roaming destinations. Looking at Airalo, I have six options:

  • 1GB with seven days validity for £4
  • 2GB with 30 days validity for £7
  • 3GB for 30 days validity for £9.50
  • 5GB for 30 days validity for £13.50
  • 10GB for 30 days validity for £21.50
  • 20GB for 30 days validity for £35

In my experience, 1GB is enough data for a few days for basics such as mapping tools, email and browsing online. You’ll need more if you plan on streaming or watching video or photo-heavy content, obviously.

Airalo doesn’t actually manage the eSIM, it just connects you to the mobile network. In this case it’s a provider called ‘Change’ which piggy backs on both T-Mobile and Verizon’s 5G networks – two of the three major US carriers.

Once you purchase an eSIM on Airalo all you have to do is add it to your phone. Apple makes this very easy on iPhones – all you have to do is scan a QR code and enter a few settings and you’ll have local 5G data within 30 seconds or so.

After you fly home it’s just as easy to remove, by going into your settings and removing the data plan.

If you want to try Airalo, then you can use my referral code ‘RHYS4258’ when you sign up or at checkout to get $3 off. I’ll also get $3 off my next plan – thank you.

    Nomad is equally impressive and can sometimes be cheaper than Airalo.

    • Jenny says:

      Nearly always cheaper in my experience over the last two years.

    • James says:

      Have been using Saily (owned by NordVPN). Comparisons over my recent trips they have always come out the cheapest of all the eSIM providers. They are on T-C-B too for extra savings.

      Their app works great allowing you to select virtual location, ad blocker and web protection.

      Three PAYG still the best way to go for my main uk line and the majority of my roaming needs.

    • MarkH says:

      Agree – Nomad has worked out cheapest for me on every trip I’ve done since starting to use eSIMs back in 2022 – mostly to Asia

    • cin4 says:

      There’s really no good reason to use airolo.

  • Ian says:

    Very much depends upon the plan.

    I have just had 5G in the USA all included.

    What does this firm charge for calls? The ability to call local numbers as well as numbers back in the UK is often important.

    If it is just data, then one needs to to rely on the likes of Skype.

    • Charles Martel says:

      This is why it’s better to use one of the networks that have retained roaming, else a call from a hotel or local restaurant can end up costing you a small fortune.

    • Colin MacKinnon says:

      In Asia, everyone calls via WhatsApp

  • Charlie says:

    Lebara do quite reasonable roaming packages with calls (e.g. 100 minutes plus 5gb data for £10 for 15 days for U.S. No eSIM but if you put your main network onto eSIM then add the Lebara SIM it is pretty hassle free once setup for roaming outside the E.U. ish area.

  • _nate says:

    Talkmobile (Vodafone) also includes EU roaming and is very cheap.

  • Hardy says:

    I used to be the biggest supporter of Airalo, but then found Mayasim which has half the price…and subsequently butemy esim from Trip.com and they are 1/4th the price. Now I can’t use the 80$ of referral credit on Airalo as it’s so so much more expensive

    • r* says:

      Not sure how much the trip price is, but maya is more expensive than airalo for the most recent esim I have for a 1gb sim.

      • Hardy says:

        Just open the trip app and you can see tons of options.
        Maya usually has discounts..I shop around. Of course if Airalo is cheap for what you want at the time, it’s best to use that. But right now, last 7 countries…it’s been more expensive

    • Tracey says:

      The referral credit is costing you nothing. Why can’t you use it?

  • Calluma says:

    Lyca in Ireland do a month of unlimited data for €20. On Three network and works well. And you can use an amount of it in UK.

    • NFH says:

      So does Three Ireland. I pay €1.60 per GB (EU price cap + VAT) with Three Ireland for data roaming in the UK, EU and EEA. Each €5 top-up lasts 6 months. No silly monthly allowances that are only partially consumed and subsequently wasted.

  • manarh says:

    The global 1yr plan works great for me as i visit 5-10 countries. £57 for 20gb but no wasted data makes it cheaper than it seems.

  • rphilippe says:

    Be very careful with Airalo.
    In December I bought their USA eSIM bundle for data and also calls. The phone number allocated didn’t work to receive calls.

    Airalo customer support is dreadful, after a week they were not able to fix it. And three weeks later they are still refusing to refund the cost.

    I bought another eSIM directly from T-Mobile for unlimited 5G data, plus calls, texts and fully working US phone number. It’s much better value if you are spending some time in the US.

    • Jingle says:

      Yup. Got Aíralo for a week in Antigua. Rarely connected. Zero customer service. Never again
