Sensorise QoSim Dual SMD Secure – Automotive


The Sensorise QoSim® M2M SIM is a dedicated platform specifically designed for environments where standard plug-in SIM cards are not suitable, either for space, or for environmental reasons. The QoSim® M2M SIM is a solution that combines traditional smart card security with a more rugged form factor.

QoSim – MFF2 SIM Card

This SIM card has a specific form factor i.e. MFF2, which is a JDEC SON-8 intended to be soldered to the Printed Circuit Board (PCB) in a M2M device and is of Automotive Grade. This document provides information about the physical and electrical characteristics of this form factor. Extended life operating system is a M2M specific operating system especially designed to maximize the lifespan of the memory chip, making it more resistant to stress (erase/write cycles) and allowing to have a very low failure rate.

In addition to the form factor the Sensorise QoSim® comes with advanced features such as

  • Multi operator profiles for maximizing the connectivity for mission critical use cases
  • Remote locking (and blocking) of the QoSim to a device
  • Remote diagnostic for tracing connectivity problems

Sensorise delivers the QoSim® package in volumes using tape reel packing method, in either 1000 pieces or 3000 pieces per reel.

The shelf-life for dry-packed SMD packages shall be a minimum of 12 months from the bag seal date, when stored in a non-condensing atmospheric environment of <40 °C/90% RH.

For certain restricted requirements, Sensorise may be able to support packages in reel size of 100.
