Installing an eSIM is easier than it sounds — no plastic card, no metal pin, no hunting for scissors at the airport. Five minutes on your home Wi-Fi and you are travel-ready. Here are the full steps, along with the common mistakes we see in support messages and how to avoid them.
Before you start: two quick checks
- Confirm your phone supports eSIM: dial *#06# — if an EID number appears, you are good to go
- Make sure the device is carrier-unlocked
The five steps
- 1 — Download the Simply app from the App Store or Google Play and create your account
- 2 — Pick your destination and plan — single country, or a regional bundle for multi-country trips — and pay (mada, Apple Pay, or cards)
- 3 — Install the eSIM from inside the app while on stable Wi-Fi; follow the prompts and approve adding the cellular plan when your phone asks
- 4 — Name the line something clear like “Travel Data” and keep your default data line on your primary SIM until you fly
- 5 — On arrival: switch the travel line on, make it the default data line, and enable data roaming for it — signal bars appear within moments
The three common mistakes
Deleting the eSIM after installing it: an eSIM installs once — if you remove it from your phone settings, it will not reinstall automatically, so keep it until the trip is over. Forgetting data roaming: the number-one cause of “no connection” on arrival — travel eSIMs need data roaming enabled for that line. Leaving apps on the wrong data line: after switching, confirm the default data line is the travel eSIM and not your primary SIM, or you may quietly burn through your home carrier’s roaming.
And your primary number?
It stays put and keeps working for calls and texts — including bank verification codes — while your data flows through the travel line. That is the best part of eSIM: you never trade your own number for internet. Set it up tonight, and fly tomorrow connected from minute one.
