Planning a European Summer: The Ten Minutes of Phone Admin That Saves You Hundreds

Share Share Share

There is a particular moment on every European trip that nobody puts in the highlight reel. You have landed in Rome or Athens or Lisbon, you are standing somewhere between the baggage carousel and the exit, and your phone is not working. The transfer details are in an email you cannot open. The friend meeting you has sent three messages you cannot see. And the only visible solution is a counter selling SIM cards with a queue in front of it.

It happens to experienced travellers constantly, because phone admin is the one piece of trip planning that feels like it can wait. It cannot, and sorting it out properly takes about ten minutes at home.

Why Europe catches Australians out

Europe is the trip where the cost of getting this wrong adds up fastest, because a European summer is rarely one country. Two weeks might take in France, Italy and Greece, with a few nights in London on the way through. Each border used to mean a new problem.

Europeans themselves have it easy. The EU's Roam Like at Home rules, in force since June 2017, mean an EU subscriber generally uses their domestic allowance across member states with no surcharge.1 Those rules do not extend to Australians travelling there. It is why a Melbourne traveller and a Munich traveller can be sitting at the same table in Florence paying wildly different amounts for the same data.

Most Australian carriers handle this with a daily roaming fee. You switch it on, you use your usual allowance, and you pay a set amount for every day you are away. For a long weekend that is perfectly reasonable. Across a three week trip it quietly becomes one of the larger lines in your holiday budget, and it lands on a bill a month after you get home, when the tan has faded and the enthusiasm with it.

The three ways to fix it

There are really only three options, and they suit different sorts of trips.

Roaming with your own carrier takes no thought at all. Everything works exactly as it does at home, including your phone number. It is the most expensive per day and the right choice for a short trip where you genuinely cannot be bothered.

A local SIM card bought at your destination is cheap and gives you a local number. The trouble with Europe specifically is that a local SIM is local. Buy one in Spain, and it is a question mark again by the time you reach Croatia. There is also the queue, the paperwork several countries now require, and the fact that your own SIM has to come out and live in your wallet for a fortnight. A surprising number of people lose it.

A travel eSIM is the newer option and the one most solo travellers and couples now default to. It is a carrier profile that downloads onto your phone as software, with no physical card at all. You buy it at home, install it before you fly, and it switches itself on when your phone finds a network at the other end.

Why one regional plan beats four local ones

The useful part of an eSIM is that your phone can hold more than one profile at a time, and that a single profile can cover a whole region rather than one country.

Providers selling Europe travel eSIM plans cover 40 destinations on one profile, the UK, Switzerland and Turkey among them, so you cross from France into Italy and nothing happens. No new purchase, no settings to change, no hunting for a shop near the station. Plans start at $21 AUD for a month, and the profile can be installed up to 90 days before you fly.

Your regular Australian number stays installed alongside it, which solves the single most common holiday disaster. Your bank sends verification codes by SMS to that number. If you have taken your SIM out and put a local one in, those codes go nowhere, and you find out at the moment you are trying to pay for something.

The ten minute checklist

Do all of this at home, on your own wi-fi, a few days before you leave rather than the night before.

First, check your phone supports eSIM. Essentially every iPhone from the XS onwards and most recent Samsung, Google and other Android flagships do. Second, check it is not locked to a carrier, which is only really a question if you bought it on a plan some years ago.

Third, buy and install the profile. It is usually a QR code and takes a couple of minutes. Keep the confirmation email somewhere you can reach offline.

Fourth, and this is the step people skip, turn off data roaming on your home profile. Otherwise your phone can quietly default back to it and you end up paying for both.

Finally, download what you will want on landing: the offline map for your first city, your booking confirmations, and the address of wherever you are going, written in a note rather than buried in an inbox.

What it will not do

Two honest caveats, because the marketing tends to skip them.

Travel eSIMs are almost always data only. There is no local number attached, so maps, messaging, email and ride-hailing all work perfectly, and ringing a local landline does not. On a European trip that rarely matters, since almost every hotel and restaurant answers email or WhatsApp, but it is worth knowing before you go.

And an eSIM buys you access to the local networks, not better ones. Coverage is whatever the local carriers provide, which is excellent in cities and patchy in the Alps and on smaller Greek islands, exactly as it is at home.

How much data you will actually use

Most people overestimate. A fortnight of ordinary holiday use, heavy on maps and messaging and moderate on photos, tends to land somewhere between five and fifteen gigabytes. What pushes it up is video calling home and streaming on long train journeys, which in Europe there are rather a lot of.

Two habits keep it down without any sacrifice. Download your maps for each city before you head out for the day, and let your photos back themselves up over the hotel wi-fi at night rather than over mobile data. If you do run short, topping up in an app takes about as long as making a coffee.

Worth doing before anything else

Of all the small jobs on a pre-holiday list, this is the one with the best return. It costs less than a magazine at the airport, it takes ten minutes, and it removes an entire category of the things that go wrong on the first day and at every border after it.

The holiday starts when you walk out of the terminal, not when you have finally worked out how to get your phone talking to someone.
