Soft SIM

Introduction

The plastic SIM cards in devices are becoming more and more complex. In addition to reduce the cost and the number of components, there is also the need to reduce device size. In special environments, it is necessary to design robust and stable devices to support high temperatures and vibrations.
The biggest challenge of the traditional SIM card is the installation and usage of the card. Due to the different network frequency bands and coverage areas of different mobile operators, the physical problems of the SIM card (such as incorrect SIM card position, damaged SIM card, damaged contacts, etc.). When switching operators or upgrading a new generation of communication technology, the SIM card needs to be replaced.

Features

With the development of electronic technology, the device has processing ability to implement Soft SIM. This technology enables all data in the traditional SIM card to be directly transmitted to the 4G/5G module of the device by the cloud service, Soft SIM has the following features:

  • Reduce the device size

    There is no need to use a traditional SIM card slot, which can further halve the size of the smallest device on the market, because the function of the SIM card is integrated into the internal chip of the device.

  • Fast development

    Design and test prototype devices faster due to the application of more integrated electronics.

  • Simplify the installation

    The device does not need to install a traditional SIM card, eliminating the need for installation steps.

  • Improve the stability

    Since fewer electronic components are used, and no traditional SIM card is required, the device can be completely sealed, making the device more adaptable to environments such as vibration, temperature, and humidity, and greatly improving stability.

  • Simplify the connection of M2M

    Soft SIM can exchange SIM card information through cloud commands, determine the best operator according to the location of the device, and greatly improve after-sales service capabilities.

Advantages

  • Security

    The SIM card information is directly read by the communication module and runs in special flash memory and RAM, thus improving the security of the network connection.

  • Low power consumption

    For devices using Soft SIM, its power saving mode can reduce power consumption by up to 200 times.

  • Agile development

    During the process from equipment development to market launch, the modules of Soft SIM remain consistent, which can bring products to market more efficiently and quickly.
