IMEISV (International Mobile Station Equipment Identity and Software Version)

The International Mobile Station Equipment Identity and Software Version (IMEISV) is a unique identifier for mobile devices that is used to identify them on mobile networks. It is a combination of two identifiers: the International Mobile Equipment Identity (IMEI) and the Software Version Number (SVN). In this article, we will discuss what IMEI and SVN are, how they are combined to form IMEISV, and how IMEISV is used in mobile networks.

International Mobile Equipment Identity (IMEI)

The International Mobile Equipment Identity (IMEI) is a unique identifier assigned to every mobile device. It is a 15-digit number that is used to identify a device on a mobile network. The IMEI is assigned by the manufacturer of the device and is stored in the device's firmware.

The IMEI is used for several purposes, including:

  • Network identification: The IMEI is used by the mobile network to identify the device and determine its capabilities.
  • Theft prevention: The IMEI can be used to track stolen devices and prevent them from being used on the network.
  • Warranty verification: The IMEI is used by manufacturers to verify the warranty status of a device.

The IMEI is also used in combination with other identifiers, such as the International Mobile Subscriber Identity (IMSI) and the Mobile Station International Subscriber Directory Number (MSISDN), to provide additional network functionality.

Software Version Number (SVN)

The Software Version Number (SVN) is a unique identifier assigned to the software running on a mobile device. It is used to identify the version of software that is currently installed on the device. The SVN is typically a 2-digit number that is assigned by the device manufacturer.

The SVN is used for several purposes, including:

  • Software updates: The SVN is used by the device manufacturer to identify the version of software that is currently installed on the device and determine whether an update is available.
  • Network identification: The SVN can be used by the mobile network to identify the version of software running on the device and determine whether it is compatible with the network.
  • Troubleshooting: The SVN can be used by customer service representatives to troubleshoot issues with the device.

IMEISV

The IMEISV is a combination of the IMEI and SVN. It is a 16-digit number that is used to identify a mobile device and the version of software that is currently installed on it. The first 14 digits of the IMEISV represent the IMEI, while the last two digits represent the SVN.

For example, if a device has an IMEI of 123456789012345 and an SVN of 01, its IMEISV would be 12345678901234501.

The IMEISV is used for several purposes, including:

  • Network identification: The IMEISV is used by the mobile network to identify the device and determine its capabilities, as well as the version of software that is currently installed on the device.
  • Software updates: The IMEISV is used by the device manufacturer to identify the version of software that is currently installed on the device and determine whether an update is available.
  • Troubleshooting: The IMEISV can be used by customer service representatives to troubleshoot issues with the device.

Conclusion

The IMEISV is a unique identifier that combines the IMEI and SVN to identify a mobile device and the version of software that is currently installed on it. It is used for several purposes, including network identification, software updates, and troubleshooting. Understanding the IMEISV is important for mobile device manufacturers, mobile network operators, and customer service representatives to provide optimal service to their customers.
