Firsty: The Trojan Horse of Roaming
How a 23-person team built a free eSIM model that threatens carriers
Firsty isn't just another eSIM app—it's a fundamental disruption to how we pay for mobile data abroad. By offering free data funded by ads, they've created a model that could force the entire telecom industry to rethink roaming.
""Firsty isn't selling data—they're selling attention, and the math works because roaming is artificially expensive.""
The Ad-Supported Data Revolution
Firsty's 'free' tier represents a radical bet: that travelers will trade 10 seconds of ad-watching for unlimited data. With 244 Trustpilot reviews at 4.2/5, the model is validated. Their 46% organic search traffic proves users actively seek this alternative to $10/day roaming fees. This isn't a freemium play—it's a complete reimagining of who pays for connectivity.
The Stealth Growth Engine
With 181K monthly visits and a global rank of #210K, Firsty punches above its weight. The 35% direct traffic rate is telling—users return. Their tech stack (Next.js, Tailwind, shadcn/ui) suggests a lean, modern engineering team focused on speed. The €6.69M funding from 2022-2023 shows investor confidence in their unit economics, even as they challenge incumbent carriers.
The keyword strategy reveals their battlefield: 'firsty esim' (1,160 searches) and 'free esim with ads' (250 searches) show they're capturing intent. Even the Dutch query 'esim bellen werkt niet' (200 searches) indicates they're solving real pain points. They're not just competing on price—they're competing on philosophy.
- The 'free' tier is a wedge: unlimited data with ads, paid plans for ad-free
- Single eSIM for 150+ countries eliminates the 'new SIM' friction
- Trustpilot rating of 4.2/5 suggests the ad experience is tolerable, not intrusive
Firsty is the Uber of Roaming
They're not building a better carrier—they're making carriers irrelevant by owning the customer relationship and monetizing through ads, not data overage fees.

I was activate the esim very easily
I was activate the esim very easily. One of the best things about this app is the customer support, an agent responds within minutes after sending message. I also tried the calling feature and it works great. The esim itself performs really well too, recommended app
First time with an eSim which was in Marrakech
First time with an eSim which was in Morocco. I opted for the First Class package which cost me £11.52 for the 4 days. After using it I realised the Comfort + would have been more than adequate for my use. Really impressed. Easy to set up and the speeds were decent. On a speed test (Ookla) I was getting 169Mbps down and 12.3 up.
Firsty eSIM worked perfectly for my…
Firsty eSIM worked perfectly for my partner and I on our big Asia trip! My partner’s eSIM worked straight away but I needed a bit of extra help from a tech angel called Julia. Julia managed to get my eSIM to work after a couple of troubleshooting steps and now mine is working perfectly too! Super fast data and exceptional customer service. What more could you want? Thanks Firsty!
Great
The support is great, the referral system is a great way to get credits, with which i can buy cheap data packages or make calls
Free data with ads but not always..
The fact that you can view ads for free data is just great. However Firsty Free is not available worldwide and in some countries where it's not available you will watch the ad but not get the free data. It would be helpful to immediately get a message saying it's not available in the country you are at rhe moment in this case. My experience with customer support has been good though!
