What is eSIM?

eSIM (embedded SIM) is a cutting-edge SIM card technology.
Unlike traditional removable SIM cards, eSIM can be integrated directly into devices without a physical card.
eSIM provides greater flexibility, lower space requirements, and enhanced device connectivity, making it ideal for use in smartphones, smartwatches, tablets, and MIFI devices.
Users can remotely activate and switch carrier services, experiencing seamless connectivity.

Links Field offers eSIM chips in various sizes, packages, and grades
providing fast and flexible delivery of integration test samples
