# Deactivated SIMs page

> Deactivated SIMs are **permanently disabled**, removed from Hologram's network, and are not able to be reactivated. SIMs are most often deactivated when they are no longer needed, a device is lost, destroyed, stolen, or on accident. You may still need to refer to past data usage or configuration information on these SIMs, and can find them here or by searching for them.

## Deactivated SIMs overview

This page is a historical record of all SIMs that have been permanently deactivated from Hologram's network. Deactivated SIMs are sorted by the most recently deactivated first.
