Flysimio eSIM review

4.1

The short answer. Flysimio sells prepaid travel eSIM plans in 184 countries, and its cheapest rate today is $0.67 per GB. Its median rate of $3.11 per GB is about 10% above the $2.83 median across every plan we track. You are paying above the middle of the market for a typical plan here, so open the country page for your destination before you buy: it ranks every seller we track on the same maths.

Have we checked these prices?

Not yet. Flysimio's prices here come from their own feed, and we have not built a checker for their shop yet, so nothing on this page has been confirmed against what a buyer actually sees. We are adding shop checks provider by provider and this page will say so when it is done.

A feed is not a shop. Feeds can list products that are not on sale, describe them differently, or carry a stale price, so a price nobody has checked again is only a number we copied.

Flysimio did not pay for this review or this rating. The rating is computed from live catalogue data and cannot be bought. If you buy through a link on this page we may earn a commission, and the price you pay stays exactly the same.

Watchdog notice

Read this before you buy from Flysimio

Flysimio has the most generous refund promise on this site, a genuine 7 day money back guarantee that survives you installing the eSIM, and their prices come straight off their own destination pages every night. The mark against them is at the till: their checkout displays a Trustpilot score higher than the one Trustpilot actually shows, and higher than the figure on their own country pages.

  • Their checkout shows 4.6 from 21 reviews on Trustpilot. Trustpilot shows 4.1 from 15, and so does their own country page. The inflated number appears at the moment of payment, which is the worst place for a trust signal to be wrong. Checked twice on 9 September 2026.
  • The refund policy is the best here: 7 days, no explanation required, and it still applies after you have installed the eSIM as long as you have used under 100 MB. They say the allowance exists so testing the connection cannot cost you the guarantee. Almost every rival voids a refund the moment you install.
  • Code ESIMWATCHDOG takes 10% off, and we tested it: a $11.75 Japan plan came to $10.57 at their checkout, with the discount already applied on arrival from here.
  • They say plainly that they resell capacity from upstream carriers and do not own the network. Most sellers leave that unsaid.
  • The company behind the brand is named only as KRAFA LLC, with no registration number, no address and no country whose law governs a dispute anywhere in the terms.
  • They publish a corrections policy and an editorial disclosure, which is unusual for a seller rather than a publisher.
  • Their prices are read from their own destination pages every night rather than from a feed, so what we show is what their page showed at the last check.

We list Flysimio because its prices are real and its plans rank on the same maths as everyone else's. We publish what we could not verify so you can decide with the facts in front of you.

Technical details

How Flysimio works, in detail

Activation
Buy on their checkout with Apple Pay, Google Pay or card. They promise the QR code by email within 30 seconds and no account is required.
Plan type
Data only. Nothing in the catalogue we import carries calls or texts.
Validity clock
The plan runs for its stated number of days. They advertise instant activation on arrival.
Hotspot sharing
Included. Their checkout states hotspot on every plan we list.
5G access
Available on their networks and stated per destination rather than per plan, so our rows leave the 5G flag off rather than claim it.
Top ups
Supported. Their checkout states top up on every plan we list.
ID checks (KYC)
Not mentioned anywhere on the site or in the terms.
Apps
No app, deliberately. Their about page makes a point of selling data without app store theatre or points programmes.
Payments
Apple Pay, Google Pay or card on their own checkout, priced in dollars, with the payment page handled by a PCI compliant processor.
Refunds
A 7 day money back guarantee, no explanation required, provided you ask within 7 days and the eSIM is either not installed or has used under 100 MB. That 100 MB allowance is there so installing and testing does not void the guarantee. Refund requests go to contact@flysimio.com.
Support
contact@flysimio.com for support, sales and partnerships, with a promise to reply within 24 hours and a help centre on the site. No phone number and no live chat.
Verified coupon

Flysimio coupon code

10% off any Flysimio plan We verified this code on the provider's own site before listing it. Call it a promo code, a discount code or a voucher, Flysimio takes one code per order and this is the one we have checked. Using it still supports us: if you buy through our links, we may earn a commission, and the coupon discount applies on top for you.

PROS

  • The strongest refund policy here: 7 days, no reason needed, and it survives installing the eSIM under a 100 MB allowance
  • Code ESIMWATCHDOG takes 10% off and is already applied when you arrive from our link
  • No app and no account to create, the QR arrives by email
  • They state openly that they resell upstream carrier capacity rather than owning a network
  • 184 destinations with straightforward fixed size plans and no unlimited small print
  • A published corrections policy, which almost no seller bothers with

CONS

  • Their checkout displays a higher Trustpilot score than Trustpilot shows, and higher than their own country pages
  • Only a company name, KRAFA LLC, with no number, no address and no governing law
  • Fifteen Trustpilot reviews to judge them by
  • Their unlimited plans are not listed here, because their pages publish a price per day without a term
  • No phone and no chat, email only
Reputation check

What real Flysimio customers say

4.1 / 5 Trustpilot, 15 reviews. Collected independently of us, checked Oct 2026. Too few reviews to influence our rating.

Most praised

  • Connection working on landing

Most complained about

  • Fifteen reviews is a small sample

Check before you buy

  • If a review score matters to your decision, take the 4.1 from 15 on Trustpilot rather than the figure their checkout shows
  • Ask for a refund within 7 days and before you pass 100 MB, because that is where the guarantee ends
  • The 10% code should already be applied when you land from here, so check it shows before paying
  • Their unlimited option exists but is not comparable here, because they do not publish how long it runs

Is Flysimio legit?

Flysimio is a real seller with 1158 live plans in our catalogue covering 184 countries, and every one of those prices is checked again at each catalogue refresh. Trustpilot shows 4.1 out of 5 from 15 reviews, collected independently of us. Our own rating of 4.1 out of 5 is computed from prices and coverage and cannot be bought.

How much does a Flysimio eSIM cost?

Flysimio plans run from $1.15 to $655.10. Ranked by real price per GB the best rate is 50 GB for 10 Days at $19.98, which is $0.67 per GB. Across the whole catalogue the median is $3.11 per GB against a market median of $2.83, so a typical Flysimio plan is dearer than the market.

Does Flysimio have a discount code?

Yes. ESIMWATCHDOG: 10% off any Flysimio plan We tested it at Flysimio's own checkout before listing it, and using it never changes where Flysimio ranks on this site.

Which countries does Flysimio cover?

184 countries in our catalogue. The cheapest Flysimio destinations by price per GB right now are Thailand ($0.67), Turkey ($0.77), Australia ($0.85). Every country in the table on this page links to its full comparison, where Flysimio is ranked against every other provider we track.

Can I use a Flysimio eSIM as a hotspot?

Included. Their checkout states hotspot on every plan we list.

Does Flysimio sell unlimited data plans?

No. Every Flysimio plan has a fixed data allowance, which is why every one of them can be ranked by an honest price per GB.

How do I install a Flysimio eSIM?

Buy on their checkout with Apple Pay, Google Pay or card. They promise the QR code by email within 30 seconds and no account is required. Buy the plan online, scan the QR code on wifi before you fly, and leave the new line switched off until you land. Then turn on data roaming for the Flysimio line and give it a minute to attach to a network. If the code will not install, our guide to eSIM QR code errors covers every message a phone can show.

We may earn a commission. It never changes the ranking or the rating.
