Quick answer
Yes. Every plan has a validity window, from 3 to 365 days on fixed plans, which starts at the first connection at your destination; data left at the end of it expires and can't be carried over. Before then, a top-up adds data and days to the same eSIM. Before the first connection nothing counts: plans can typically be installed up to 180 days after purchase.
When data expires
- Fixed plans: when the validity ends or the data runs out, whichever comes first.
- Daily plans: each day's allowance ends with that day, and the plan ends after the number of days you bought.
- An expired eSIM can't be topped up; buy a new plan for the next trip.
Extend it before it ends
In My eSIMs, “Add more data” adds a top-up to the running eSIM: on a fixed plan it adds data and days, on a daily plan it adds days. Auto top-up can do it for you, at 90% used on fixed plans and before the last day on daily plans.
Frequently asked questions
Is there an eSIM whose data never expires?
Not at VoyaSIM: every plan has a validity window, and the longest run for 365 days.
Do I get a reminder before it expires?
Yes: an email when one day is left, and alerts as the data runs low.
