eSIM Technology Overview
Definition & Connectivity: An eSIM is a digital SIM that enables mobile network connectivity via virtual identity recognition technology. UUPAY provides comprehensive 5G and 4G coverage; however, connection quality and speeds vary based on local carrier infrastructure, geographical location, and device hardware compatibility.
Software-Defined & Multi-Profile Support: Unlike traditional physical SIM cards, an eSIM is software-programmable. This allows your device to store and manage multiple eSIM profiles simultaneously, enabling seamless switching between different plans or carriers.
Data Usage Policy: The data package purchased for a specific destination represents a total allowance for the duration of the plan’s validity. Please note that data does not reset daily; users have full autonomy to distribute their usage throughout the entire lifecycle of the package.
