Firsty eSIM Review 2025: Free & Flexible Global Mobile Data for Travelers

Firsty eSIM is a next-generation mobile internet solution designed for global travelers who want to stay connected without the hassle of SIM card swaps, high roaming charges, or unreliable public Wi-Fi. Unlike traditional eSIM providers, Firsty introduces a freemium model that gives users free internet access worldwide after watching a short ad.

This innovative approach ensures that even without a paid plan, users can message, use maps, send emails, or call online—crucial services for anyone on the move. With just one eSIM for all countries, Firsty removes the complexity of travel connectivity and makes mobile data accessible to everyone.

Whether you’re planning a vacation, traveling for business, or backpacking across continents, Firsty eSIM adapts to your budget and bandwidth needs.

Free Mobile Data Anywhere with Firsty Free

The core innovation of Firsty is Firsty Free—a plan that offers a basic internet connection completely free of charge. Here’s how it works:

Open the Firsty app and watch a 30-second advertisement.
Unlock free basic internet access that allows you to:
- Send WhatsApp, Messenger, or Telegram messages
- Make online voice calls
- Navigate with Google Maps or Apple Maps
- Use Uber, Bolt, and other essential apps
- Check your emails and notifications

This service is a game-changer for travelers who need reliable connectivity for essential tasks—especially in emergencies, unfamiliar cities, or when SIM vending machines and Wi-Fi aren’t an option.

Instead of paying €10 or more per MB in roaming charges, you get a stable and cost-free connection on demand, just by spending half a minute watching an ad. It’s perfect for budget travelers, students, digital nomads, and anyone who wants to stay connected without spending.

Upgrade to Fast Global Internet: Comfort Plus & First Class

Need more speed? Firsty offers two premium tiers designed for travelers who require high-speed, full-access internet:

Comfort Plus

Price: From €1 per day, with decreasing daily cost when you buy more days
Speed: Fast enough for video calls, browsing, streaming, and uploading content
Flexibility: Pause and resume the plan at any time, so you only pay for the days you use

First Class

Price: Slightly higher than Comfort Plus
Speed: Fastest tier with top-tier network performance globally
Ideal for: Business travelers, digital nomads, and content creators who need optimal performance

Both plans are prepaid, commitment-free, and easy to activate directly in the app. Firsty will automatically connect you to the fastest network available in your region, ensuring a smooth internet experience no matter where you are.

You can also activate your plan whenever you’re ready, so there’s no risk of data going to waste. Just install the eSIM once, and you’re ready to travel the world.
