esimzu is a Belgian online shop for travel eSIMs. You buy a data bundle for your destination online, pay in euros and are connected within two minutes with a QR code. No physical SIM card, no app and no subscription. Your own SIM card and number keep working.
Every country page shows which local network your eSIM uses, how fast it is and how long the bundle is valid.
All prices are in euros, with a lowest-price guarantee. Every month we compare our prices with Airalo, Holafly, Saily, Nomad and Ubigi on their official websites. In October 2026 esimzu was the cheapest in 45 of 48 comparisons. Where someone else is cheaper, we say so: see the price comparison.
You pay by Bancontact, Apple Pay or card, or with crypto. After payment your QR code appears on screen straight away and also arrives by email. It is best to install the eSIM at home on wifi before you leave.
Since its start in June 2026 esimzu has delivered almost 400 eSIMs to travellers, mostly for Morocco, Turkey, Indonesia, Europe and the Balkans. Many customers come back for their next trip.
Customers rate esimzu 4.3 out of 5 on Trustpilot (15 reviews, October 2026).
Support is available in Dutch, French and English:
