Update timeline

  1. investigating Jul 28, 2025, 03:03 PM UTC

    Our monitoring systems have detected possible service disturbances to Essentials3 SIM subscriptions. Engineers are actively investigating. We will provide additional details in 15 minutes.

  2. investigating Jul 28, 2025, 03:35 PM UTC

    Currently, our 4G Data Sessions may be affected, primarily with establishing new sessions; at the same time, 2G/3G sessions should not be impaired. Our engineering teams are working with our roaming partner to resolve the issue as quickly as possible.

  3. investigating Jul 28, 2025, 04:05 PM UTC

    We are continuing to investigate this issue.

  4. investigating Jul 28, 2025, 04:58 PM UTC

    We have escalated the issue to the Executive Level with our carrier partner as our monitoring systems show signs of degradation on both 2G/3G and 4G networks now. Our partner is working diligently to reduce network congestion and restore normal service performance. Devices may continue to experience degraded behaviour, including issues with both new session attempts and existing connections.

  5. identified Jul 28, 2025, 05:40 PM UTC

    Our partner carrier is actively performing mitigation actions. Our monitoring systems show signs of improvement.

  6. identified Jul 28, 2025, 06:22 PM UTC

    We continue to see some improvement while our roaming partner is still working to bring full restoral of services. Some customers may still experience degraded services with establishing new sessions and maintaining current ones, especially in the UK and the United States.

  7. identified Jul 28, 2025, 07:11 PM UTC

    Our roaming partner is still working to restore services back to original levels. While we are seeing more immediate improvements for our 2G/3G data sessions, we still see more impact for 4G data sessions.

  8. monitoring Jul 28, 2025, 08:49 PM UTC

    Our partner carrier has restored service, and our engineers are monitoring it to ensure stability. If no further impacts are observed during our monitoring period, we will consider this resolved.

  9. resolved Jul 28, 2025, 10:17 PM UTC

    We have not observed any further issues during our monitoring period. We are considering this issue resolved.
