About e-sim.onl
Affordable eSIMs for travelers. Transparent prices, instant delivery.
Our mission
We started e-sim.onl with a straightforward goal: make mobile connectivity simple and affordable for anyone traveling internationally. Traditional roaming charges are unpredictable and often shockingly expensive. Buying a local SIM card in every country means hunting for shops, dealing with language barriers, and swapping tiny cards in and out of your phone.
eSIM technology eliminates all of that. You buy a plan before you leave, scan a QR code, and you're connected the moment you land. No physical SIM, no store visits, no guesswork. We exist to make that experience as smooth as possible.
How our pricing works
e-sim.onl is an independent reseller. We buy eSIM data plans from eSIM Access, a wholesale eSIM platform, and add our own margin to cover payments, support and running the site. The price shown on each plan is the price you pay at checkout, in US dollars, with no activation fees.
Global coverage
We offer 3,000+ plans across 200+ countries, from popular destinations like the US, Japan, and France to less common ones like Mongolia, Madagascar, and Fiji. Whether you're backpacking through Southeast Asia, on a business trip to Europe, or island-hopping in the Caribbean, there's a plan ready for you.
Our regional plans cover entire continents, so if your trip spans multiple countries you don't need to buy a separate eSIM for each stop. One plan, one QR code, seamless connectivity across borders.
How it works
Choose a plan
Pick a country or region, then the data and days you need.
Install the eSIM
Open the QR code on another screen. On your phone, open the mobile data (Cellular) settings, choose Add eSIM and scan it, or type the codes. Do this on Wi-Fi before you leave.
Turn it on when you land
Switch mobile data to the eSIM and turn on data roaming for that line. The plan is prepaid, so there are no roaming charges.
Our technology
e-sim.onl is built on Cloudflare's global edge network, which means the platform loads fast no matter where in the world you're accessing it from. Our API runs on Cloudflare Workers, our data lives in D1 and R2, and our frontend is delivered from edge nodes in over 300 cities worldwide.
Your dashboard shows data used and remaining, updated about every hour. If your eSIM supports top-ups, a Top up button appears in My eSIMs once the eSIM is in use. The extra data goes onto the same eSIM, usually within a few minutes. If it doesn't, buy a new plan; it arrives as a new eSIM.
Our commitment to you
- 30-day refund policy: If your eSIM has not been installed on a device, you can request a full refund within 30 days of purchase.
- Email support: We reply to every message within 24 hours. Use our contact form or email us at support@e-sim.onl.
