How an eSIM actually works
An eSIM is a SIM card written into your phone instead of pushed into it. What that changes, what it does not change, and the one thing that catches people out.
Installing and activating an eSIM
Install on wifi at home, keep the line off, switch it on when you land. Here is the full sequence including the settings people forget.
eSIM or roaming
Roaming is simpler. A travel eSIM is usually cheaper outside your home zone. The arithmetic that decides it takes about two minutes.
eSIM or a local SIM card
A local SIM is cheaper per gigabyte and gives you a local number. A travel eSIM costs you no time. Which matters more depends on the trip.
Getting online the moment you land
Airport wifi, SIM counters and eSIM activation compared for the arrival you actually have: tired, in a queue, with a taxi to find.
