How long you can use the plan, for example 7, 30 or 365 days.
Validity is the period during which the data on a plan can be used. When it ends, any data left is lost, even if you have not used it all.
Some plans start the clock when you install the eSIM, others when you first connect or when you arrive. The activation rule is written on the plan page.
What to check
- Match validity to trip length, with a few days of margin
- Check whether the days start at purchase, first use or arrival
