What is the stamp card?
Last updated October 14, 2026
Collect a stamp for each eSIM you buy for £8 or more. Six stamps earn a £4 voucher for your next eSIM order of £15 or more.
The stamp card is a simple punch-card-style reward that runs alongside points.
Each eSIM in an order earns one stamp when what you pay for it is £8 or more. "What you pay" means after any discount, excluding tax and fees; a discount on the whole order is shared across the eSIMs in it. Top-ups don't earn stamps. An order with three qualifying eSIMs earns three stamps.
Six stamps earn a £4 voucher for your next eSIM order of £15 or more. The £15 counts eSIM plans only, and the voucher can't be used on a top-up.
The voucher is valid for 180 days.
When stamps count
A stamp counts once that eSIM has passed its refund window, 21 days from the day it's issued. If an eSIM is refunded in full it loses its stamp; after a partial refund the stamp stays only if what you still paid for it is £8 or more.
How it's different from points
Points scale with spend and turn into vouchers of different sizes; the stamp card is flat — six qualifying eSIMs, one £4 voucher. They run side by side, so a single eSIM can earn both.
