OmniSIM 1.3 SKU Update - December 2025

The following advisory was sent out on December 16, 2025.

You are receiving this message because you have ordered a version of OmniSIM™ 1.3 SIMs that is being replaced with a new SKU version.

The new SKU version incorporates a new MSISDN (Mobile Station International Subscriber Directory Number) range into the OmniSIM product. The MSISDN prefix is +883460.

This new MSISDN is a non-geographic number, providing greater flexibility for deployments by removing location-related constraints and adding enhanced connectivity security hardening to prevent public reachability via SMS or Voice.

With this new MSISDN range, Circuit Switched Voice (over 2G and 3G networks) and direct Device to Device SMS services are no longer supported.

For full details of what’s in the new SKU versions, check out OmniSIM 1.3 and "What is New in OmniSIM 1.3?" and "What is New in OmniSIM 1.4?" on KORE Docs.
