Introduction

A physical SIM card is a hardware chip that can be used in a device. It is a user identification card, which stores user data, authentication methods, and passwords for the system to identify users. At the same time, the SIM card connects users with the system and exchange information between them.

Currently, GSL provides commercial and industrial physical SIM cards.

  • Commercial physical SIM cards: made of common plastics and applicable to common consumption scenarios.
  • Industrial physical SIM cards: made of injection molding and ceramic materials. Industrial physical SIM cards are resistant to high temperature, moisture, vibration, corrosion, electromagnetic interference, and have long service life.

The following table lists their differences.

Type

Description

Commercial

There are four types of commercial physical SIM cards.
  • Commercial plug-in SIM: common SIM (2FF).
  • Commercial plug-in 2-in-1 SIM: common (mini) SIM and micro SIM, excluding nano SIM.
  • Commercial plug-in 3-in-1 SIM: common (mini) SIM, micro SIM, and nano SIM.
  • Consumer SMD SIM: 5 mm x 6 mm and 2 mm x 2 mm SMD SIM, which can be welded to devices.

Industrial

There are three types of industrial physical SIM cards.
  • Industrial plug-in SIM: common SIM (2FF).
  • Industrial plug-in 2-in-1 SIM: common (mini) SIM and micro SIM, excluding nano SIM.
  • Industrial SMD SIM: 5 mm x 6 mm and 2 mm x 2 mm SMD SIM, which can be welded to devices.
