Top-up.

A top-up adds extra days to the end of a live plan — same eSIM, no new QR code, no reinstall. Buy it from Account → Top-up and the days append automatically.

Any time before your plan expires. If it has already expired, buying a fresh plan for the same country is usually identical in price — the day rate is the same.

Days are consecutive calendar days from activation, not a bank of hours — so a 5-day top-up ends 5 days after it starts. Buy in the increments you actually need.
