Polaris eSIM
No more settling for bad internet abroad. We use the best technology to deliver the most stable connections.
Why We Do This
One of the most frustrating things about traveling abroad is having no internet. Google Maps goes blank, calling home is choppy, and finding restaurants becomes a guessing game. Roaming plans cost a fortune, and random eSIMs might give you dial-up speeds.
We got fed up with this experience, so we decided to build something better ourselves.
Most travel eSIMs on the market actually use roaming connections — your data gets routed through servers in other countries before coming back. Sounds roundabout, right? It feels even worse: high latency, slow speeds, and frequent disconnections.
Polaris eSIM focuses on one thing: Local Breakout connectivity. Your phone connects directly to the local carrier network — no detours, no throttling. When you're in Japan, you use Japan's local network, not a signal bounced through a third country. Simply put, browsing abroad feels just like being at home.
Three Things We Care About
No Compromise on Network Quality
We only offer Local Breakout connectivity — your phone connects directly to local cell towers. No detours, no throttling, no random disconnections. The experience is just like using a local's network.
Pricing, Laid Out Plain
Price, data, duration — everything is clearly listed. No hidden fees discovered abroad, no confusing terms. Plan your budget before you leave with complete peace of mind.
Great Tech Makes Great Products
We use AI to develop the platform, handle customer service, and translate into multiple languages. Not to follow trends — because it genuinely produces better results, and the savings go straight to you.
This Entire Platform Was Built Together with AI
Not AI doing touch-ups — AI was involved from start to finish
The website you're looking at right now — from the shopping cart, credit card payments, eSIM activation, order management, to the very text you're reading — was entirely built with AI. We use Claude Sonnet and Claude Opus by Anthropic, among the most advanced AI models available.
This isn't 'ask AI to write a snippet and piece things together.' AI was involved throughout: architecture, coding, debugging, optimization — even translations into nine languages. Claude Sonnet handles daily feature development; complex problems go to Claude Opus. Two AI models plus engineers built an entire commercial platform.

Why Did We Choose to Develop with AI?
Simply put, we're a small team. The traditional approach requires hiring many engineers, spending months, and burning through budgets — and the result might still be incomplete. The longer the launch takes, the longer users wait.
We found a smarter way: working directly with Anthropic's Claude AI. It doesn't just write code — it helps design architecture, find issues, and run tests. This lets us build a full-featured, high-quality platform with minimal staff. Development is several times faster, and the cost savings go directly into pricing — giving you premium eSIM quality at better prices.
What Does This Mean for You?
🚀 New Features, Fast
Report an issue today, and we might fix it tomorrow with a new feature the day after. Traditional companies might take weeks — we get it done in days.
🔒 More Stable, More Secure
AI continuously checks the code for vulnerabilities and issues. Your payment information and personal data go through rigorous security checks.
🌐 Nine Languages, No Problem
Traditional Chinese, English, Japanese, Korean, Thai, Vietnamese, Spanish, German, French — no matter what language you prefer, our website has you covered.
💰 Better Prices
Without a large engineering team, the savings on personnel costs go directly into pricing. Same quality Local Breakout connectivity, more competitive prices.
We're Just Getting Started
Automatically selects the fastest connection, lets you check remaining data anytime, and proactively reminds you to top up when running low. We're not just selling a data card — we're taking care of your internet from departure to return.
