Introduction

Do you have any of the following problems when designing a SIM-equipped housing?

"I want to make the board smaller, but is there any good way?"

"How should we proceed with measures for waterproofing and dustproofing around the SIM slot?"

"Isn't it possible to collectively manage contract information from a remote location when using SIM with many IoT devices?"

"It takes time and effort to insert and collect SIM cards when you want to use communication functions with many IoT devices."

For those who are troubled by the above points, this page introduces SoftSIM, which does not require a SIM card.

What is SoftSIM

SoftSIM is a technology that writes and provides a communication profile to a virtual machine in a secure area within a communication module. Since a SIM card is not required, SoftSIM has the following advantages suitable for IoT and 5G.

　・Significant cost reduction (parts cost, distribution cost, SIM mounting cost, optimization of communication cost, etc…)
　・Miniaturization of substrates (communication equipment)
　・Improved durability and reduced failure rate (contributes to waterproof and dustproof design)
　・Multiple communication profiles can be stored
　・ API function to control the opening / closing of communication lines (customer cooperates with SoftSIM management company's line management system)
　・SIM card theft prevention
