The usage period is counted in 24-hour units from eSIM activation, and is provided free for the number of days equal to your rental time converted into 24-hour units (e.g. Aug 25 11:30 – Aug 29 10:00 = 94h 30m → 4 days). This may differ from the number of calendar days used for the rental fee. If you need a longer period or more data, you can pay only the difference on the payment page or purchase additional plans at eSIMTOK.
