How Data Amounts and Validity Work
When the clock actually starts, and why you should install before you leave.
How Data Amounts and Validity Work
Every plan combines an amount of data with a validity period — the window in which that data can be used.
When the Clock Starts
Validity begins when the eSIM first connects to a local network in its coverage area — not when you buy it, and not when you install it.
Regional and Global plans: if you are already in a country the plan covers, the eSIM activates as soon as it connects.
Why This Matters
Installing before you travel costs you nothing, and it saves you hunting for reliable Wi-Fi when you land. So install your eSIM at home, on Wi-Fi, before you leave: it activates when you arrive and connect to a local network.
Buying in Advance
Buying early never starts the clock, so you can buy weeks ahead of a trip.
When Data Runs Out Before Validity Does
The connection stops but the eSIM stays valid. A top-up restores service on the same profile without reinstalling anything.
