Airalo review: how to 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.

Last year, almost all UK mobile networks brought back international roaming charges for all destinations, including those in the EU.

This was a major disappointment, as free European roaming was unbelievably convenient for frequent travellers.

Anyone on EE, Three or Vodafone will now be charged for EU roaming when they take out a new mobile contract (existing contracts are usually exempt from EU roaming costs, so it may be worth sticking with that you have even if slightly cheaper deals are available).

For example, Three will now charge you £2 a day just to use your normal allowance in Europe. Outside of Europe it can be as much as £5 per day.

Airalo review

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 from Three once my contract ended last month.

(Vodafone also offers free roaming on some of its 4 Xtra plans, starting at £18/month.)

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.

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.

Using Airalo as an esim to beat roaming charges

Airalo – website here – bills itself as the world’s first eSIM store that gives you access to 190+ eSIMs globally, including a range of local, regional and global SIM cards.

I have now used Airalo twice – on my trips to Malaysia and Qatar – and have been very impressed. The process is extremely simple, as demonstrated by this infographic:

How Airalo works

(In reality, you do not need 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 even leave the UK, which 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?

In a few weeks I am heading to the United States to try out Virgin Atlantic’s new Austin route, which is unfortunately outside of my O2 free roaming destinations. Looking at Airalo, I have four options:

  • 1GB with 7 days validity for $4.50
  • 3GB with 30 days validity for $11
  • 5GB for 30 days validity for $16
  • 10GB for 30 days validity for $26

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, 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 AT&T’s 4G 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 4G 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. The Airalo site is here.

    I have used Airalo while travelling around the world these last years (with forced hiatus). It has always fitted my needs and is very handy when you only need data. Prices seem to be good and the fact you don’t need to buy anything on arrival saves precious time. Just be aware there country and regional sims. So you need to check a little if you are going to be jumping from country to country.

  • David Shamash says:

    Lebara does not charge for EU roaming and has a cheap £1/month plan for international phone and data

  • Mark says:

    As has been mentioned Three pay as you go still in includes roaming across Europe and a number of other countries (e.g. the US, Australia and a handful of Asian countries).
    Their offers include a prepaid 24GB data SIM that lasts up to 24 months. Sometimes priced in low £30s (I recently paid £34 on Amazon), you can load them with credit for PAYG calls and texts. If, like me, you have a phone with dual physical SIM slots (no eSIM), you can also use with a separate PAYG sim or just use for roaming with a normal pay monthly SIM in the other slot.

    Ideal for me as I don’t use huge amounts of data, calls or texts, so it lasts the full 24 months and therefore costs under £1.50/month for up to 1GB/month average including roaming across a fairly wide range of counties.

    • GavinK says:

      I believe the Three 24 month data sim has a roaming limit of 12GB. It still may be a decent enough buy for some depending on their needs.

  • James says:

    Does anyone know if there is a service that provides eSim functionality on a physical SIM?

    I have just bought a new phone that has 2 physical SIM slots but no eSIM support annoyingly.

    • dougzz99 says:

      Yes, someone mentioned it recently, hopefully they’ll see this and answer.

    • dougzz99 says:

      Look at eSim.me

    • Mikeact says:

      Can certainly recommend eSIM.me…a German outfit who are really switched on re eSim. Ideal for most/any Android phone that does not have eSim capability or single sim phones. I used it successfully until I bought a Samsung s22 with capability built in.
      nb Rhys is slightly wrong, the s20 does not have eSim in built functionality or my old S20fe didn’t, hence I used eSIM.me .
      On my 22 I have 7 esims loaded and one physical sim…a BT one that doesn’t support eSim for private contracts .
      The sooner UK suppliers wake up and smell the coffee the better. Three continue with promises, promises…even Vodafone need to wake up.

  • Dave says:

    Sounds great. Question As a non-techy. If I’m signing up to this on my iPhone, how do you then scan the QR code that’s on your iphone?

    • Rhys says:

      Dunno haven’t tried it that why but it probably isn’t a QR code on the app but an install button!

    • yonasl says:

      You can use the app to install the esim without the QR code.

      On an iPhone you can also screenshot the QR and the it will analyse it and display the QR as a link.

  • Simon says:

    Can someone please explain something – on landing, I switch on my phone after having already loaded up with the e-sim. How does the phone know (iPhone in my case) to use only the e-sim and not use your roaming data from your physical UK sim? Or do you simply make sure that mobile data is switched off in settings and it automatically uses the e-sim??

    • Rhys says:

      You can turn off roaming on your U.K. plan (on iPhone at least). Or you can turn off a SIM card entirely.

      You can also choose which plan to use as default for calls, testing and data.

      • Simon says:

        So presumably you switch off the UK SIM which means that you CANT use whatsapp on the UK number.

        • Anuj says:

          No because WhatsApp doesn’t require your phone number to work (only to login)

    • Mark says:

      On Android, assuming it works the same way as two physical SIMs, you can turn data roaming on and off for individuals SIMs and also control which one is used separately for outgoing calls, texts and data.

  • MarkH says:

    Used an esim and Airalo for the first time recently in NY and worked a treat. So much better than wasting time signing up for a physical sim, which I’ve also always found expensive in US.

    Will definitely look to use more in future especially as I hadn’t realised I could keep my UK sim active and separate the comms channels.

    How was the signal using Airalo in Malaysia?

    I see it doesn’t use Celcom, which ime is the best Malaysian network by far.

  • Oh! Matron! says:

    Got to admit, I wish I knew this a month ago in Singapore. Whilst getting a local eSim with M1 ($12 for 7 days) was easy enough, it was a surprising hour out of my day. It does look like you’re paying a little for the convenience, but we’ll worth it.
