What is SIM card multiplexer?

Answer 1

A SIM card multiplexer is a device that allows multiple SIM cards to be connected and accessed by a single mobile device or system. It enables the switching between different SIM cards without needing to physically change them, which can be particularly useful for applications requiring multiple network providers or for managing different phone numbers. This technology is often used in IoT devices, telecommunications, and mobile applications to enhance connectivity and flexibility.
