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.

    Have been using esims for years across over a dozen countries. Really is a game changer. Would day that I would almost never use airolo though.

    Apart from the fact it’s more expensive, other providers have better regional deals, ensure forced roaming is allowed and better partner networks.

    • memesweeper says:

      Airalo is so much cheaper than roaming off a UK plan I’m not sure chasing down a slightly better deal is worth the time spent for a holiday. If you regularly visit the same places, though, the effort might be worth it.

      In terms of UK networks Spusu is cheap, has EU roaming, and runs off EE (and unlike any other EE MVNOs, actually has access to all the EE frequencies, so works in some places where only EE has coverage).

      • cin4 says:

        It takes less than five minutes and I don’t travel for less than a month at a time.

  • GillyDee says:

    I bought the Airalo global SIM with calls, text & data last April; used in Bolivia, Colombia, Uganda, Greece, Japan, China and now in Hawaii. Only one glitch in connection which CS resolved within 12 hours. Will definitely renew this year and I’ll let you know (humble brag alert) if it works in Mongolia🐆

  • QFFlyer says:

    3 Hong Kong is worth looking at to have something always there, 365 day validity PAYG plans with data and a local number (although you do have to satisfy Real ID requirements because of Chinese law) and you can topup in the app. I prefer having plans that work across most of the world.

    As it is, 3HK is a backup, my Optus plan still includes 5GB roaming per month, covering most of the world, but there are no plans available with the 3 main Aussie carriers any more which include roaming, and they’ve ended their partnership with Qantas (which is the plan I’m on, after they booted everyone off the incredibly generous $40/m plans including unlimited domestic and roaming calls and 4GB roaming data), so my days on that plan may be numbered.

    I’ve added a few free eSIM data plans as and when they’ve come up (for some reason I ended up with one in Singapore) and they work well, but remember to set your phone to low data mode (you usually have to set it per line, so if it’s on for your normal line, the new eSIM probably won’t have it selected by default), because it’ll burn through data in no time otherwise.

  • lak says:

    I decided to go with Roamless instead of Airalo or Nomad. The reason being you just top up credit and then it uses data on a pay as you go basis and doesn’t expire. I found the prices comparable at $2.45/GB for the US which is cheaper than all except for the 20GB Airalo package. Data is actually measured in MB so if you only use 100MB it’ll be $0.25

  • Catman99 says:

    “enabled by new eSIM technology found in virtually all modern handsets”

    That might be true if you have £1K phones like Apple or S range Samsungs but hardly any Android phones have this capability even the flagships of normal brands!!!!!

  • Eleanor says:

    I’m with O2 and until recently used to have a pretty comprehensive travel inclusive sim plan with them. For a trip to Asia (China, Japan & HK) in September, I needed to use an alternative as the countries weren’t included and tried Airalo. They were brilliant and I too installed prior to arrival and had a seamless experience throughout the trip with their Asia e-sim. Have since downgraded with O2 and lost their expensive travel plan. I have used Airalo multiple times for travel outside the EU this year. 👍🏻

  • Adam says:

    My son visited a college friend in San Francisco over Christmas and was there for 10 days. He used Airalo and it cost £30 in total. I’d recommend Honest Mobile’s Smart SIM at £3.75 a month that gives unlimited use of 100 or so popular apps (social media excluded) but no voice calls.
    Personally I’m on O2 with the travel inclusive bolt on (which I get for free as I’m also on virgin media at home) so get free roaming in the EU, US and 26 other countries.

  • Saltrams says:

    I have a £5.60 PAYG monthly Lebara SIM via MSE. I wasn’t aware I can keep getting new deals via MSE but I’m OK with under £6 for my package anyway.
    I go to Italy for 4-6 months every year. The first time I did this, I was caught out by the “fair usage” policy, which shut off my data because I used more abroad than in UK. I’m a low data user in UK but now have to set a reminder every 30 days to turn off wi-fi and stream 4K YouTube video on the last day of my contract to use up the data 🙄. That works but one has to wonder why such tedious workarounds are forced upon us.
