The trip notebook / Five practical tools
Choose your next question.
Start with your scenario. Four tools work entirely locally; the connection snapshot only runs when you agree.
Buying an eSIM? Find the missing terms before you choose.
Does this eSIM fit your trip?
Planning a workday? Put fast-data limits beside your workload.
What does “unlimited” leave for work?
Arriving late? Check when the validity clock could start and stop.
Plan the clock, not just the QR code.
Carrying two connections? Look for the failures they still share.
Is your backup really a different path?
Before a client call? Compare this room’s primary and backup.
Take a room-level connection snapshot.
Estimate the whole trip’s data budget.
The arithmetic, made visible.
days × people × [(video hours × video GB/hour) + (audio hours × audio GB/hour) + browsing GB/day + other GB/day] × (1 + buffer/100)
The starting assumptions are 1.2 GB/hour of video calls, 0.08 GB/hour of audio calls, 0.25 GB/day of browsing and messages, and 0.5 GB/day of uploads or other use. These are editable planning examples, not field measurements. Count shared usage once; downloads and system updates belong in other use.
