Stay connected in 200+ countries — instant QR delivery
Eflexsim
A new eSIM brand · Just launched

We made the eSIM
we wished we had on
every flight we've taken.

No subscriptions, no SIM swaps, no surprise bills. Just a QR code, a few seconds of setup, and data that works the moment you land.

Why we started

Travel keeps getting easier.
Staying connected didn't.

You've probably done the dance. You land somewhere new — maybe with a connecting flight still ahead — and the first decision isn't where to eat or how to get to the hotel. It's what to do about your phone.

Pay for roaming and accept whatever the bill becomes. Hunt for an airport SIM kiosk and try to read a contract in a language you don't speak. Or just turn data off and wander around half-blind for the next ten days.

We wanted something a traveler would actually enjoy using. So we built it. That's Eflexsim.

How it works

Pick a plan, scan the QR, you're online.

01

Pick where you’re going

Country, region, or worldwide. Pay once for what you need.

02

Scan the QR you get

Activates as a second line on your phone. Your real number stays where it is.

03

Land and you’re online

No swapping a physical SIM. No airport kiosks. No surprise bills.

What we promise

The deal, in writing.

What we'll never do

Refunds within 14 days. Eligible if the eSIM hasn't been activated, or if it doesn't work in your destination. Partially-used data isn't refundable. Read our refund policy.

  • Auto-renewing subscriptions or hidden monthly charges
  • Surprise overage fees — your plan stops, it doesn't bill you more
  • Asking you to swap your physical SIM or change your number

What we'll always do

  • Show the full price in your currency, before you click pay
  • Send a clear notification before any plan ends or top-up is needed
  • Keep your existing SIM and number untouched

Real support, real humans

If something goes wrong with your eSIM at 2 AM in a foreign airport — and we know that feeling — there's a human at the other end of the chat. 24/7, no script, no bot pretending to help. We answer because we've been there too.

Carbon-neutral, by default

Travel has a footprint. So does data. We offset the emissions of every byte routed through our platform — funded out of our margin, not a checkbox on your receipt. It's included in the price, the way it should be.

Coverage

We connect to the same towers your home carrier would.

We resell Airalo's network of tier-1 local carrier partners. When you land, your phone connects to whichever partner has the strongest signal where you are.

Honest answers

“You're new — are you actually legit?”

You just launched. Why should I trust you with my trip?
You shouldn't — yet. You should buy the smallest plan we offer, install it, and see if it works. We'd rather earn the rest. The technology under the hood (eSIM, GSMA, partner networks) is the same as every other provider. What's new is us. The bet you're making is that we'll handle support and pricing better than the established names — and we're betting the same.
Is the eSIM itself the same quality as a "big" provider?
Yes. We're a brand on top of the same infrastructure. When you install an Eflexsim, your phone connects to the exact same tier-1 carrier towers it would on any other eSIM service — Vodafone in Spain, Orange in France, NTT in Japan, and so on. Speed, coverage, and reliability are determined by those carriers, not by us.
What happens if my eSIM doesn't work when I land?
Open the chat — there's a human waiting, 24/7. If we can't fix it within an hour, we refund the plan in full. We don't make you fight a support ticket queue from a foreign airport.
How does refunding work?
If your eSIM hasn't been installed yet: full refund within 14 days. If it's been installed but never connected to a network: full refund within 7 days. If it connected and something went wrong on our side: case by case, but we lean refund.
Where are you based and who owns this?
Eflexsim is independently operated and self-funded. We're not a side project of a bigger telco, and we're not flipping for an exit. The goal is a small, sustainable, profitable eSIM brand that travelers actually enjoy using. Press inquiries: press@eflexsim.com.
Will my data be private?
Your traffic runs through partner carriers like any other eSIM — we don't inspect it. We hold the minimum we need to deliver the service (email, plan history, install status) and we don't sell it. Full details on our Privacy page.
