Simbase Outage History

Data service degradation affecting Green SIM profile. Devices may have difficulty establishing new data sessions. Existing sessions remain unaffected. Affected countries: XX

[2026-06-11 10:06:45] - Incident status was updated. Summary: Investigating degradation in data service performance. Devices may have difficulty establishing new data sessions. Existing sessions remain unaffected. Actively monitoring the situation.

Devices are experiencing failures when establishing data sessions on 4G networks using the Blue SIM profile. The issue is affecting a limited number of devices and is being investigated with the network operator. Affected countries: XX

[2026-06-10 09:10:19] - Incident status was updated. Summary: Investigating data session establishment failures on 4G network affecting a limited number of devices. Issue appears related to a previous fix and work is ongoing to identify and resolve the problem.

We are currently experiencing issues with the O2 network in the UK. As a precautionary measure, we have temporarily restricted access to O2 while we work with our roaming partner to investigate the root cause. Affected devices may show as connected to O2 but will not have active data. We recommend ensuring your device is configured to automatically select a network, as alternative supported networks : EE, Three, and Vodafone remain fully operational. We will provide further updates as our investigation progresses. We apologise for any inconvenience caused. Please note: this issue affects Black Profile SIMs used in the UK only.

[2026-06-04 13:48:25] - Incident status was updated. Summary: Investigating connectivity issue affecting devices in Guinea network. Customers may experience intermittent connectivity and service degradation. Team is actively working to identify root cause and restore normal service.

We have identified an increase in provisioning errors affecting Blue and Yellow Profile SIMs. As a result, some SIMs may fail to Enable and remain stuck in the “Enabling” state. As a precaution, we recommend that customers avoid disabling Blue/Yellow Profile SIMs until further notice. SIMs that are already enabled and in session are not affected.

Our systems have identified a potential issue for Blue and Yellow Profile SIMs. Our engineers are actively investigating the situation to resolve it as quickly as possible.
