Is Onomondo Down?

This incident has been resolved. Service for SIMs using IMSI range 20416 has remained stable throughout the monitoring period, and devices are connecting and establishing data sessions as normal. The issue was caused by an incident at one of our upstream network partners following planned maintenance on their side. We are following up with the partner to understand the root cause and provide an incident report thereafter. If you still see devices that are unable to connect, please contact our support team. --- [2026-11-08T14:28:39.448+01:00] (monitoring) Service for SIMs using IMSI range 20416 has fully recovered. Network traffic and data sessions are back to normal, stable levels, and devices are able to establish new data sessions as expected. We will continue to monitor network performance. If you still see devices that are unable to connect, we recommend rebooting the device or resetting the modem, and contacting our support team if the issue persists. --- [2026-11-08T13:58:49.156+01:00] (monitoring) Service for SIMs using IMSI range 20416 has largely recovered, and the number of active data sessions is almost back to normal levels. Most affected devices have now reconnected. We are still seeing elevated network activity as remaining devices re-establish their connections, so some devices may take a little longer to come back online. We will continue to monitor and post a further update once we have confirmed full recovery. --- [2026-11-08T13:36:06.844+01:00] (monitoring) Our upstream network partner is implementing a fix, and we are beginning to see service recover for SIMs using IMSI range 20416. Devices are gradually regaining the ability to establish new data sessions. Devices that were unable to connect during the incident may take some time to reconnect. If a device has not reconnected, we recommend rebooting it or resetting the modem. We are continuing to monitor the situation and will post a further update once we have confirmed full recovery. --- [2026-11-08T12:55:17.755+01:00] (identified) We remain in close contact with the partner and will post an update as soon as the fix is in place. --- [2026-11-08T12:56:23.414+01:00] (identified) Our upstream network partner has confirmed they are working on a temporary solution to restore service. Devices on SIMs using IMSI range 20416 may continue to fail to establish new data sessions until then, while active sessions remain unaffected. --- [2026-11-08T12:00:06.727+01:00] (investigating) Since approximately 09:15 CET, devices on SIMs using an IMSI starting with 20416 are failing to establish new data sessions. Devices with an active session are not affected, but devices that disconnect or reboot may be unable to reconnect. SIMs on other IMSI profiles are not affected. The issue has been traced to an incident at one of our upstream network partners following planned maintenance on their side. We are in direct contact with the partner and have escalated the issue. No estimated resolution time is available yet. We are continuing to investigate issues on IMSI range 20416.

All systems are now performing nominally. We have seen a full recovery in signalling and authentication rates. If you are still experiencing issues please contact our support team via support@onomondo.com. Thank you again for your patience. --- [2026-11-03T13:43:53.562+01:00] (monitoring) Our incident response team has identified the issue affecting signalling and authentication on IMSI range 23450; having applied a fix to this problem we are now observing rapid recovery and SIMs successfully re-authenticating.  We are continuing to monitor the situation and will provide further updates shortly. If you are still experiencing issues, please reach out to our Technical Support Team via support@onomondo.com We apologise for the inconvenience and thank you for your patience. --- [2026-11-03T13:01:12.818+01:00] (identified) Our incident response team are continuing to investigate.  We have successfully identified a root cause affecting IMSI range 20416.  We are observing improvements for both signalling and authentications on this range and devices should begin recovering shortly.  We are continuing to investigate issues on IMSI range 23450 and expect to provide an update shortly. --- [2026-11-03T12:30:49.518+01:00] (investigating) We are currently observing abnormal behaviour in all signalling and authentication of devices on our network. We are actively investigating the root cause and we will provide updates as soon as possible.

This incident has been resolved. --- [2026-11-03T11:18:10.002+01:00] (monitoring) An issue in our rate limiter was identified and has been fixed. Monitoring --- [2026-11-03T11:05:54.813+01:00] (investigating) We are currently experiencing issues with Traffic Monitor in the app. We are investigating.

We are scheduling general system maintenance for our core network. Maintenance is planned for Nov 18, 2026, starting at 9:30 UTC, with an expected duration of up to three hours. During this time, we will be updating services of our core network responsible for authentication on 2G, 3G, 4G LTE, LTE-M, and NB-IoT. No service disruptions are expected. Customers should not experience authentication rejections due to this maintenance.

We will be performing upgrades to our GRX links in cooperation with our GRX provider. Temporary and minimal network instability may occur during this work. We will monitor the environment closely throughout the maintenance window.
