Technical Architecture & Single-eSIM Profile Deployment
How Does Saily’s Single-eSIM Architecture Work?
Traditional eSIM marketplaces require users to download separate ICCID profiles for every new country. Saily utilizes a reusable global profile framework. Travelers download the Saily eSIM profile once to their iOS or Android device during initial setup. When traveling to a new country, purchasing a local data plan automatically provisions connectivity onto the existing profile without requiring manual QR code scans or installation steps.
Network Roaming and Speed Performance
Saily partners with Tier-1 telecommunications providers in major markets, including True in Thailand, Mobifone in Vietnam, and major tier-1 cellular carriers across Europe and North America. According to field performance studies by industry group GSMA, digital network routing latency on roaming eSIMs averages 80–120ms, making Saily suitable for VoIP, video conferencing, and navigation.
