About Onetel

Onetel started from a straightforward idea: roaming abroad shouldn't drain your wallet, eat your time, or add stress. We built the most honest, traveller-friendly eSIM storefront on the web.

Our Mission

We pull eSIM data plans from multiple providers across 150+ countries, so you get the best price every time — no hidden fees, no locked contracts, and no plastic SIM cards to toss.

How It Works

Pick a plan by destination, pay securely in seconds, and get your eSIM QR code by email. Scan it on your iPhone or Android and you're online — no shop visit, no queue, no roaming shock.

Who We Are

We're a small crew of engineers, product designers, and travel enthusiasts spread across Europe and Asia. All of us know the sting of a huge roaming bill or hunting for a SIM at the airport — Onetel is the fix we wished someone had built.

Our Values

• Transparency — No hidden fees. The price you see is the price you pay.
• Simplicity — Under 2 minutes from purchase to connected.
• Reliability — 24/7 support, plus a straightforward 30-day refund on unused eSIMs.
• Sustainability — eSIMs are digital, so there's no plastic waste.
