What is an IMEI?
The IMEI (International Mobile Equipment Identity) is a unique, usually 15-digit number identifying a cellular modem on the network.Why is the IMEI missing for a SIM?
- Network did not provide it: Some networks do not provide IMEI with every data session. Some networks do not provide IMEI consistently between sessions. We show the IMEI whenever it is available, and default to showing the last known IMEI when we have it.
- No connections yet: SIMs that have not connected to a network will not have IMEI information.
- Device/SIM swapped: If a SIM was moved to another device, you may see the previous IMEI until a new session occurs.
Note: As a best practice, store the device’s printed IMEI alongside the SIM’s ICCID in your inventory before deployment. If you change modules or move SIMs, the IMEI will change.
What does the SIM details page show if no IMEI is available?
If no IMEI has been seen for a SIM, the SIM details page shows “Not available” for Last known IMEI.
