Twelve things to do before you fly
Tick them off; this browser remembers where you got to.
Last updated September 4, 2026
Most of what goes wrong at the arrivals hall could have been settled at home in ten minutes. This list is in the order it should actually be done.
0 of 12 done. The list is stored in this browser only.
Why the order matters
Checking the handset comes before buying, because if it cannot take an eSIM nothing else matters. Installing comes before flying, because installation needs the internet you do not yet have on arrival.
Frequently asked questions
Is my ticked list sent anywhere?+
No. It is stored in this browser only, never sent to a server and not tied to any account.
How far ahead should I do this?+
At least two days out, so there is time to fix anything that fails.
Do I need to remove my home SIM?+
No — keep it for calls and bank OTPs; just switch off roaming data on that line.
