The phone bill that started everything
Two weeks in Southeast Asia. Temples, street food, overnight trains. An incredible trip — until the phone bill arrived.
€214 in roaming charges. For using Google Maps and sending photos on WhatsApp.
That was the moment. Not the first time it happened, but the last time I was willing to accept it.
I'm Mariano, and that trip is why Telcomia exists.
The problem nobody was solving well
I looked at what was available. Local SIM cards that required hunting for a phone shop in a language I didn't speak. Pocket WiFi devices that died by 3pm and had to be returned at the airport. eSIM apps with confusing interfaces and prices that varied wildly for no obvious reason.
Every solution felt like it was designed by telecom engineers, not by travellers. The people building these services had never stood in a Bangkok airport at midnight, exhausted, trying to figure out why their data wasn't working.
I had. Many times. And I knew there had to be a better way.
What we set out to build
Telcomia started with three principles:
1. The best price in every country — automatically.
Most eSIM providers use a single connectivity network. That means you're stuck with whatever deal they negotiated, even if it's not the cheapest option for your destination.
We built something different. Telcomia works with multiple connectivity partners and routes your data through whichever network offers the best rate in each country. If Provider A is cheapest in Europe but Provider B wins in Latin America, you automatically get the best deal regardless.
You don't see any of this. You just see a fair price.
2. Set up in 2 minutes, not 20.
We stripped away everything unnecessary. No account verification hoops. No confusing plan names. No 47-page terms and conditions popup.
Pick your country. Choose your data. Pay. Scan the QR code. Done.
The entire process takes less time than ordering a coffee.
3. Feel the destination before you arrive.
This one is personal. When I book a trip to Japan, I want to feel Japan from the moment I start planning. Not stare at another generic white website with stock photos.
Telcomia adapts its look to your destination. When you select Japan, the experience feels Japanese. Brazil feels Brazilian. Spain feels Spanish. It's a small detail, but travel is about the experience — and we think that should start from the first click.
What makes Telcomia different
We're travellers who built a better way to stay connected. We're travellers who learned enough about telecom to solve our own problem.
We don't lock you into one network. Our multi-provider architecture means you always get the best available rate. If a new provider offers better prices in a country, we switch — and your price drops.
We cover 200+ countries. Not 50. Not 100. Two hundred and eight. From Iceland to Indonesia, Portugal to Papua New Guinea.
We're transparent about pricing. No hidden fees. No activation charges. No "fair usage" surprises. The price you see is the price you pay.
We're a real company. Telcomia OÜ, registered in Estonia (EU), registration number 17447975. Real company, real address, real people. Not a faceless reseller hiding behind a landing page.
Who's behind Telcomia
Telcomia was founded in 2026 by Mariano Carneiro, a product engineer based in Spain with a decade of experience building digital platforms.
The company is registered in Estonia through the e-Residency program — not because it sounds cool, but because Estonia has the most digital-friendly business environment in the EU. Our company formation, banking, and tax compliance are all handled digitally. No paper, no bureaucracy, no wasted time.
The technology runs on modern infrastructure: a web app that works on any device, secure payments with secure payment processing, and automated eSIM delivery. No app store download required — just visit telcomia.com.
Our commitment
To travellers: We will always offer the best price we can. Not the highest margin we can get away with — the best price that lets us keep the lights on and keep improving.
To honesty: If we don't cover a country well, we'll tell you. If a competitor has a better deal for a specific use case, we won't pretend otherwise. Trust is worth more than a single sale.
To simplicity: We will never make things complicated to seem more premium. Simple is better. Always.
