IMSI Range Mismatches in Multiple Countries

Resolved after 4 days 16 hours, on February 22, 2022.

investigating Feb 23, 2022, 12:46 AM UTC

The service provider engineering team has begun enqueuing new updates to replace the update containing the error that uses the incorrect IMSI in various countries and updates to correct this for SIMs that have already downloaded the update. The update containing the error has been picked up by ~8% of active SIMs. The countries where a non-preferred IMSI will be used after the update is received represent <5% of Super SIM activity in aggregate. This issue does not impact devices connecting to networks in the United States. If you believe you may have devices offline due to this issue, please open a support ticket and a member of our support team may be able to assist you with identifying which networks you may need to enable to allow your devices to reconnect. We will provide another update in 8 hours or as soon as we have more information.
