Why eSIM is the Future of Travel Connectivity
Before we dive into Saily’s features, let's address the foundational question: How to use an eSIM for international travel? An eSIM (embedded SIM) is a digital SIM card built into your smartphone. Instead of inserting a plastic card, you download a profile via a QR code or an app. Once installed, you can switch between carriers and data plans seamlessly. For travelers, this means arriving at your destination, turning on your data, and immediately having internet access—no physical store visits required.
