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.

  • Daniel says:

    Another benefit of eSims is you can leave your main Sim turned on to receive SMS and calls (at least on Android), which is really handy when needing to get SMS for 2FA or just to stay in touch with people who may need to call you. You just use the eSim for data.

  • Gordon says:

    I have used O2 for many years, and have a O2 Travel Inclusive Zone Bolt On (No extra charge) for toll free calls and data usage to the following countries,
    Argentina, Honduras, Australia, Madagascar, Botswana, Mexico, Canada, Myanmar, Chile,
    New Zealand, Colombia, Nicaragua, Costa Rica,
    Panama, Ecuador, Paraguay, El Salvador, Peru,
    Greenland, Rwanda,Guatemala, United States,
    Guinea, Uruguay, Guyana, Venezuela, Yemen.

    Currently using in Colombia, for navigation purposes, and it’s a godsend.

    For Asia, I use any reasonably priced eSIM, as others have said.

    • ADS says:

      the O2 Travel Inclusive Bolt On is NOT free!

      “For the fixed price of £7 a day (for the days that you use it), you get unlimited minutes, texts and data in 75 destinations outside Europe (including USA, Canada, Australia, New Zealand & Mexico)”

      the O2 daily charge is similar to the price of a month’s local SIM

      • Gordon says:

        I beg to differ, as i said, I’ve been with O2 many years and know what is and is not free, see below a screen shot from my O2 app, just so you know that my bolt on’s are indeed free.

        • Lady London says:

          Are you perhaps grandfathered as a longstanding customer to get this Gordon?

          • Gordon says:

            I’ve been with O2 for around 20 years, only because when my contract is up, I call the cancellation team, (I mean the retention team) and I have always had a better offer, in line with the cheapest alternative providers, I pay less than £20 a month for my fully inclusive contract, I will be perfectly honest, I don’t know how this has occurred, you may be correct, but I’m not going to ask and look a gift horse in the mouth!
            I just wanted to clarify that I do not pay for any of my bolt on’s!

            I must say it is very convenient not having to worry about roaming charges to a lot of countries.

          • ADS says:

            very fortunate to be grandfathered on such terms

            for normal customers the £7 a day charge is highway robbery!

  • Paul says:

    Of course none of this would be necessary if we were in the EU. I was with three till they pulled roaming to follow the corporate greed herd. Used O2 but they increased prices but also excluded Hawaii from the USA which was ridiculous, so now with Lebara. In Vietnam I used a locally purchased e sim that gave me a data allowance for 30 days that I could not have used in. Year for around £6.
    eSIM have been a god send but personally I would go for local esims rather than the big operators

    • Kowalski says:

      I don’t recall having Worldwide roaming included with my EE contract before the UK left the EU?

    • pigeon says:

      Yeah, lots of thing you can say about leaving the EU, but roaming prices in the US and Vietnam are unrelated to brexit.

      • Paul says:

        Pre the madness 5three offered full cover across Europe and many other countries, notably French colonies! I do take the point about global roaming but the loss of EU roaming was simply greed. Even now my EU friends can call anywhere in the EU from wherever they are in EU. German phone calling Spain from Greece. Some U.K. roaming allows this but not all

  • ABZ_Neil says:

    I’m with Tesco Mobile ( O2 piggyback ) and have good 4G/5G here in Aberdeen so no complaints, I also can use my minutes/data in EU.

    Travelling I used Airalo last year for the first time in Qatar and Thailand. I was really impressed as I had full strength 5G in Bangkok and Pattaya and unlimited data and 100 mins local calls that I used for restaurant bookings. The eSIM allowed me to use my phone as a hotspot and tethered my young daughter’s iPad. A very happy and content daughter. This year we are off to Malaysia (subject to Dreamliner engine issues) and will again use Airalo.

    You can also earn AVIOS on Airalo at a rate of 15 AVIOS / £1 spend in the AVIOS shopping portal.

    • Kwab says:

      That’s probably more to do with the excellent 5G infrastructure in Thailand. I have used 3 different eSIM providers in Thailand and they have all been excellent. Try Airalo in Vietnam and it’s a whole different story….

  • Jack says:

    any suggestion / solution for going to the USA but my phone will not accept an esim please ?

    • CamFlyer says:

      Will ypur phone accept multiple physical SIMs? If so, get a Three PAYG SIM. With a £10/month rolling subscription (and possibly other options for less), you will have free US roaming.

      • Jack says:

        Yes, it has 2 sims .. appreciate your answer, thanks

      • Mark says:

        You can also buy pre-loaded data SIMs from Three that offer free roaming in Go Roam counties including the US. E.g. the 24GB version valid for 2 years comes in around £35:

        https://www.amazon.co.uk/Three-Mobile-Pay-Broadband-data/dp/B0D1KWQ7BK/ref=asc_df_B0D1KWQ7BK

        Although sold as data sim the ones I’ve had in the past came with a number that can be called and, with pay as you can credit added, could be used to make calls as well.

        • Mark says:

          Worth noting that they are now restricted to half the data (i.e. 12GB for the 24GB version) being used for roaming. That didn’t used to be the case but the rest can be used in the UK, e.g. if your main SIM is PAYG, for top-up if you need a bit of extra data or to provide coverage on a different network if your main SIM isn’t on Three (or a virtual network that uses it).

    • Gordon says:

      There are many physical Standard, Nano & Micro sims etc available online, or even from the country you wish to visit.

    • Richard says:

      Get a 5ber sim. It gives old phones esim functionality. I use one in my Huawei Mate 20X and it has worked great. You control the loaded esim via the 5ber app.

      If you need a sim quicker get a Three 10gb PAYG sim from Amazon for about £9 as PAYG still allows US roaming. 👍

      On the esim Mobimatters is good, got a 15gb esim for $11.99.

      • Mikeact says:

        Or eSIM.me as an alternative. To prove it worked I fired up an old Nokia, and moved an old esim to it.

    • Iain says:

      Try esm.me

      It’s a physical SIM which converts older non esim compatible phones to being able to use them.

      I used it several times on my old phone, works perfectly.
      Ironically, it doesn’t work well with Airalo as that app tries to change the settings.

  • Mark says:

    A couple of people have already mentioned it but another plug for eSIMDB. Just download the app or use the website, tell it where you’re going and it provides price ordered comparison with filtering options (such as amount of data and length of time). It also offers discounts and links straight through to the chosen provider to order.

    Paid £2.57 last week for 7 days 4G in Grenada (up to 1GB) with eSIM4Travel.

  • Richard says:

    Get a 5ber sim if you have an older phone with no esim capability. I use one in my Huawei Mate 20X and it has worked great. You control the loaded esim via the 5ber app.

    On the esim Mobimatters is great, in comparison to Rhys’ Airalo example I got a 15gb esim for $11.99.

  • Norfolk&Chance says:

    Careful with Airalo. Have used it 5 or 6 times. Once in the USA it stopped working (for my wife’s sim and mine) for 5 days and Airalo said it was a system issue. Similarly in tanzania it stopped working on new years eve when out with family and I couldnt get a taxi home. Airalo said it was a problem with local provider.
