When does my package start?
Installation, activation and validity are three different moments.
Installing does not start the clock
Install at home or on Wi-Fi whenever you like. Nothing is used until you connect.
Validity starts at first connection
Your package starts when the onesim line first connects to a network at the destination. From then, the plan runs for its full validity period.
Crossing borders
On a regional plan, entering another included country does not restart or reset validity.
