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.

  • Ironside says:

    I started taking SIM-only plans when I realised the benefits of unbundling the device from the line. I’ve been on my current tariff since before the UK collapsed out of the EU, hence I still have free Europe-wide roaming for not much money.

    Eventually, the annual above-inflation price increases will make it unviable and it will make sense to change, but by that point the UK may well be in negotiations to rejoin anyway.

    • Rich says:

      Get Lebara, roaming is included and it’s so much cheaper than the likes of Vodafone whose network it uses -. then you won’t have to keep dreaming about something that is never going to happen and you can get on with your life.

    • Reney says:

      I have a monthly contract with O2 that is annually renewed at April, when the annual prices adjustment comes in. I go on uswitch and ‘switch’ to a new O2 contract at April usually the pre inflation price with more data. Have not had an annual price increase since I learnt this trick a few years back.

    • cin4 says:

      It’s not been financially sound to do anything other than paym in the UK for over a decade.

  • Kowalski says:

    eSims are definitely very handy unless you need a local number for calls. I use Telegram’s @Mobile, you can pay via Telegram’s crypto wallet, TON or bank card. Very convenient and lower cost than Airalo for most countries, including the US

  • TimM says:

    P.S. ID Mobile uses the Three network and allows free roaming to 50 counties its pay-monthly and SIM-only plans, the latter as short as 1 month. ID Mobile also often shows as the cheapest way to buy a new iPhone if you require any included minutes or data.

    • Helen says:

      We use ID mobile too 30GB for £7pm, then use EasySim for US 10GB £16 but with offers & discounts you can get it cheaper.

  • Barrel for Scraping says:

    It’s giffgaff not GiffGaff!

  • Bobby says:

    In the interests of balance – is this article sponsored? At the very least I imagine Rhys will be getting some free roaming from the referrals.

    My big problem with these providers is how do I know whether I’m getting a full service or a throttled watered down plan. Those with O2 in the USA used to be throttled to 500MB (I think it’s now 2GB – still slow) but it shows as 5G. They exempted google maps and Facebook from being throttled giving a really weird experience.

    So when I read ‘Airalo is actually using international sims to make it all work’ – how do I know if I’m getting the best service the network supports or some bottom rate ‘it technically meets what we said it would’.

    • Alex says:

      It does read like an Airalo press release. And having looked into Airalo previously, the local sims are virtual networks owned by Airalo and often at vastly inflated prices for the local market without the guarantee you’re not throttled. While it isn’t a good deal, if you don’t want to deal with getting a local eSIM, it likely does the job.

    • Rob says:

      Let me remind you that we ban commentators who claim we are breaking the law by running sponsored content without the legally required disclaimers.

      Rhys doesn’t need the credit – he has enough for about 500 trips because the amount used per purchase is restricted. He is just disclosing that he gets some in the interests of disclosure.

    • Rhys says:

      When I first wrote a version of this in 2022 Airalo was one of the only providers out there. Now eSIM companies are a dime a dozen. But I’ve been happy with Airalo, it’s easy, smart and works so I’ve stuck with it.

      • ed_fly says:

        Suspect that there are number of cheaper providers, some may be great, some may be very, very bad. I trust HfP to recommend decent providers, who I can rely on. Thanks for the article.

      • ChrisBCN says:

        Rhys, time to start shopping around! Otherwise you are just like a Vodafone user who stays with Vodafone, paying extra for no reason…

        • TGLoyalty says:

          “For no reason” is harsh I moved away from Vodafone however I know going to some of these newer providers isn’t always an easy experience. Customer support can be terrible when things go wrong.

          • ChrisBCN says:

            I take your point, although customer support can be a disaster at any company from time to time (also I know there will be some people who have good deals at Vodafone for various reasons)

  • tontoro says:

    I have used Airalo quite a lot, it’s good. However, if you’re going to the USA this can be a lot better. It’s cheaper than the equivalent Airalo package for data ($27 for 25GB over 30 days) AND you get free unlimited local calls.

  • Domo1915 says:

    Personally had bad experience with Airlo so once bitten twice shy. Customer service was non existent after the esim didn’t work and they eventually backed down only when I said that they were breaking law not offering a cash refund as up to that point they would only give me the “air credit” for a non working esim.

  • TGLoyalty says:

    Tried this one two years ago paid and the eSIM never actually worked.

    The support was terrible and I just couldn’t be bothered to waste any more time chasing £10.

    • meta says:

      You probably didn’t follow the full instructions and missed a step. You actually have to click to agree that you will follow step or lose the esim. It’s not complicated if you’re a bit concentrated, but if you rush it then of course you might miss the step where it says that you need to click twice for the same screen.
