Staying connected abroad should be effortless
Zesimer is a travel eSIM service built for people on the move. Buy a data plan online, scan a QR code, and get fast mobile data the moment you land — no physical SIM, no roaming bills, no hassle.
Why we exist
Anyone who travels knows the routine: land in a new country, hunt for a SIM card kiosk, queue up, swap out your card, and hope it works — or worse, switch on roaming and brace for the bill. It's slow, stressful, and completely unnecessary in 2026.
eSIM technology already lives in most modern phones. We built Zesimer to put it to work: a simple way to buy data for almost anywhere in the world, delivered instantly, ready before you even leave home. You keep your own number, and you only pay for what you need.
What we do differently
Plenty of companies sell eSIMs. Here's what we focus on.
Coverage that goes further
Plans for 190+ countries — not just the popular tourist spots, but the harder-to-reach places too, so you're covered wherever you go.
Honest, upfront pricing
One clear price before you buy. No hidden fees, no surprise roaming charges, no fine print designed to catch you out.
Reliable networks
We connect you to leading local carriers for fast, stable 4G/5G data — the same networks locals rely on, not bottom-tier resellers.

Built by travellers
We're a small, focused team that uses our own product on every trip. That keeps us honest: if something is confusing, slow, or overpriced, we feel it too — and we fix it. Our goal is simple — make getting online abroad so easy you stop thinking about it, and just enjoy the journey.
