Free airport wifi: what it is good for and why it is not enough

It gets you out of a fix and lets you down exactly when you need it most. How to connect properly and what happens once you leave the terminal.

Airport wifi is an excellent safety net and a terrible connectivity plan. It works for letting people know you have landed and for checking email while you wait for your bag. It stops working the exact minute you walk out of the door with your suitcase and need a map.

The four practical problems

  • Registration. Many networks want an email address, a phone number or even a flight number, and some send a code by text that can take a long time to arrive while roaming.
  • The time limit. It is common for the free connection to last a while and then ask for payment to continue.
  • The speed at certain hours. With two long-haul flights landed at once, the network does what it can.
  • That it ends at the door. Outside the terminal there is nothing, and that is exactly where the taxi, the stop and the address hunt begin.

How to connect properly, if you are going to use it

  1. Check the official network name. It is usually written on the signs in the terminal, and it is what tells the airport network apart from one with a similar name.
  2. If the portal asks for details, give the minimum. A secondary email address for this sort of thing solves the problem for good.
  3. Reject anything unnecessary in the portal's cookie and advertising notices.
  4. Turn off automatic connection to that network when you are done, or your phone will try to latch onto networks with the same name elsewhere.

What is reasonable and what is not

Nearly all traffic is encrypted these days, so the classic risk of somebody reading your passwords on an open network is far smaller than it was a few years ago. The two risks that are still real are different ones.

RiskWhat to do
A fake network with a plausible nameCheck the official name on the signs
Portals asking for too many detailsGive the minimum, or use a secondary email
Sessions that expire mid-taskDo not start long tasks there

For banking, purchases and anything important, your own mobile data is better. Not out of fear, but because not depending on somebody else's network is simply easier.

The mistake of planning it as your only option

This is the most common trap of budget travel: assuming there will be wifi at the airport, at the hotel and in cafes. There will be, and all three let you down at exactly the moment that counts, which is the journey between them.

  • The taxi that cannot find the address.
  • The train leaving from a different station than the booking said.
  • The restaurant you have to find on foot.
  • The change of plan you have to pass on by message.

What is worth setting up in advance

If you are going to rely on wifi until you reach your accommodation, at least carry the city map downloaded, the address saved as a marked place and your bookings in a format you can open with no connection.

The right order for switching your phone on when you land is in what to do after landing, step by step.

Frequently asked questions

Is free airport wifi safe?

For browsing it is reasonably safe, because almost all traffic is encrypted. The real risks are fake networks with a name close to the official one and portals that ask for more details than they need.

Can I install an eSIM on airport wifi?

Technically yes, but it is a bad idea: registration can drag, the network can be slow and the profile has to download in full. Install it at home on your own wifi.

Why does it ask me for so many details?

Because the access portal uses them commercially. Give the minimum and keep a secondary email address for this sort of thing.

How long does the free connection last?

It depends on the airport. It is usually time-limited and then offers to continue for a fee.

Is wifi enough for the whole trip?

No. Wifi covers the hotel and the cafes and fails on the journeys in between, which is exactly where the map and your messages are really needed.
