Install your eSIM before you fly, not at the airport

By Coco Lin Β· Β· updated

The most common eSIM mistake is a timing one: people install at the airport on patchy Wi-Fi, or they activate too early and lose a day. Here is the sequence that has never failed me.

Install early, activate late

Installing and activating are two different steps.

  • Install loads the plan onto your phone. Do this at home over Wi-Fi, the night before.
  • Activate starts the clock on your validity. Do this after you land.

Most providers let you install without starting the validity period, so you land with the plan ready and only turn it on when you need it.

My airport routine

  1. On the plane, before landing, I make sure the travel line is added and my home line has roaming off.
  2. When we taxi in, I switch the travel data line on.
  3. I open maps to confirm I am connected before I leave the gate.

By the time I reach passport control I already have data for the taxi app or the train ticket.

If it does not connect

  • Toggle airplane mode off and on. This forces the phone to find the local network.
  • Check that the travel line is set as your data line in settings.
  • Make sure data roaming is on for the travel line. On a travel eSIM this is normal and expected.

Nine times out of ten a quick airplane mode toggle fixes it. Pick your plan on the country pages and set it up the night before, and arrival is the easy part.
