About Flysimio
Flysimio is built by travelers who got tired of $15/day roaming, expired airport kiosks, and competitors that bury the unit price. We sell data. That's it.
The short version, straight.
Most travel eSIM companies started as adjacent products — VPN companies adding a data line, ad-spend giants chasing the next category. We started by counting receipts. A 30-day plan in Japan from the biggest competitor was $13. We knew the wholesale rate. We knew the markup was the brand budget, not the network.
So we built Flysimio to do one thing well: get you online when you land, at a price that doesn't need an excuse. No app-store theatre, no points programs, no bundled features you didn't ask for. Just data.
Principles we stand on.
Plain pricing
No region-restricted promos, no expiring credits, no "introductory" rates that double on month two. The price you see is the price.
Real carriers
We partner directly with tier-1 carriers — NTT Docomo, Vodafone, Telefónica. Not MVNO resellers. You get the same speed locals do.
Honest comparisons
We tell you when a competitor is better for you. Saily has VPN. Holafly has stacking. Airalo has the bigger app. We compete on price and clarity.
Refunds without theatre
7 days, no questions, full refund. No qualifiers, no hold music, no escalation tier.
“We treat the price you see as a promise. If the wholesale cost drops, your price drops too. We don't store the difference.”
Meet the team.
Writers and travelers who have personally tested eSIM plans in 40+ countries across five continents. Every country guide is rewritten on a 90-day cycle to track carrier price, coverage, and policy changes — and we name the carrier behind each plan so you can verify the network yourself.
Multilingual support handling 1,000+ traveler inquiries per month in English, Spanish, French, and Arabic. Average first response under 4 hours, with 24-hour coverage for activation issues so a 3am problem in Lima gets a human reply.
Direct integrations with tier-1 carriers — NTT Docomo, Vodafone, Telefónica, T-Mobile, Turkcell, and more. We validate every plan against live carrier inventory daily and monitor activation success rates per network, per country.
