KORE OmniSIM Reach 1.3.1 - Update

KORE updated its OmniSIM Reach 1.3 product in September 2025 to incorporate a new MSISDN range being introduced to the OmniSIM product.

Non-Geographic MSISDN Update: The latest version introduces a Non-Geographic MSISDN with the prefix 883460. This shift means that Peer-to-Peer SMS and Voice services are no longer supported in this OmniSIM version. This does have the advantage of blocking any Spam SMS.

There has been no change in the connectivity options for the product from OmniSIM Reach 1.3 to 1.3.1. We see no impact to customer deployments when moved to the new SKU's. Unless you use P2P SMS or Voice, your sales contact should be able to provide support in the transition.

KORE OmniSIM 1.3 - Release Highlights

OmniSIM has a new look

• Press Release: https://www.korewireless.com/company/news/kore-continues-to-support-reduced-plastic-use

• Other changes include having the SKU on the back of the card body so it is easier to identify the product.

• Update to eSIM Profile Management (SGP.02) settings, to bring OmniSIM in line with best practice for eSIM and from experience of downloading profiles in the field.

  • Rollback Timer is a timer within the OS of the eSIM that waits a period of time to allow a profile to get connectivity before the ISD-R Fall-Back to the previous profile. Due to OmniSIM being in Roaming and multiple IMSI to get connection we have seen issues with profiles rolling back before connectivity was achieved. This OS parameter has been increased from 1 min to 5 mins

  • Default Notification Protocol Priority: The order of the protocol used by the eUICC to notify the RSP of profile download/installation or state.

  • Move to data (HTTPS) first reduces the SMS used at first attach which for OmniSIM will resolve issues of subscriptions moving out of the test state due to SMS.
