Installing an eSIM takes a few minutes and either a QR code or a direct app-based install, but where you do it matters — airport WiFi is the wrong place to start this process.
Quick answer: Install your eSIM at home on a stable WiFi connection, ideally a day or two before you fly, not at the departure gate or after landing in Cape Verde.

Why install before departure, not on arrival
A rushed install on unfamiliar or congested airport WiFi is where most setup problems start — installing calmly at home means you can also confirm everything’s working before you’ve committed to needing it, unlike the situation covered in the eSIM not working guide for troubleshooting after the fact.
The QR code method
Most eSIM providers deliver a QR code by email after purchase — scanning it through your phone’s cellular settings adds the eSIM profile, though you’ll typically need a second device or a printed copy since you can’t scan a code displayed on the same screen you’re installing to.
Confirming your phone can install one at all
Not every phone supports eSIM, and installation will simply fail on unsupported or carrier-locked devices — check the phone compatibility guide before you start, particularly if you’re using an older or previously-used device.
What happens after installation
Installing the eSIM profile doesn’t activate it immediately in most cases — it typically switches on once you land and your phone detects a Cape Verdean network, covered in the activation guide.
Setting up before a multi-island trip
If your itinerary covers several islands, installation is a one-time step regardless — the same eSIM profile works throughout, as covered in the island hopping guide for planning the rest of the trip.
FAQ
When should I install my Cape Verde eSIM?
At home on stable WiFi, a day or two before departure.
Should I install it at the airport instead?
No — congested or unfamiliar airport WiFi is a common cause of failed installs.
Do I need a second device to install via QR code?
Usually yes, since you can’t scan a code on the same screen you’re installing to.
Does installing activate the eSIM immediately?
Not usually — activation typically happens once you land and connect to a local network.
What if my phone won’t let me install it?
Check compatibility and carrier-lock status before assuming it’s a setup error.
Do I need to reinstall for each island I visit?
No, one installation covers the entire archipelago.
Final Recommendation
Install at home, on WiFi, well before you leave for the airport. See the activation guide for what happens once you land.
