Before you fly Tick each step on this device. For eSIM size and plans see eSIM finder and data calculator .
eSIM bought and ready to install A fixed-GB plan is enough for a few GB. An unlimited day plan costs more. For two or more countries, compare one regional plan with separate country plans. Buy on Wi-Fi and install before you fly. Not sure on GB? Use the data calculator. Open related tool Physical SIM plan chosen (if not using eSIM) Local prepaid, home multi-SIM, or a travel SIM: know where you buy or swap the card and what ID you need. Roaming set on purpose Either turn data roaming off and rely on eSIM/local SIM, or leave it on with a cap you accept — not the default surprise bill. Offline maps downloaded Download the region in Organic Maps or OsmAnd (no account), or your usual maps app, while on Wi-Fi. Test that the dot still moves in airplane mode. Voykit pages saved for offline Open the cities and tools you need in the trip planner so this device caches them before you leave. Open related tool VPN decision noted Decide yes or no for this trip, install if yes, and know whether your bank or streaming apps block VPN IPs. Banking app works abroad Travel notice filed if your bank wants one, biometrics tested, and a backup card that is not locked to home-only use. Open related tool 2FA backup codes saved offline Print or store backup codes for email, bank and booking sites somewhere that does not need SMS to the home number. WhatsApp / iMessage tested Send a test to someone at home on Wi-Fi only; confirm your number still receives SMS for codes if you rely on it. Hotel Wi-Fi backup plan Know whether the stay includes usable Wi-Fi, a paid tier, or whether you will hotspot from mobile data instead. Nothing leaves this browser.
