Summary

From 2026-03-10 14:52 to 2026-03-10 23:32 UTC, some Soracom IoT SIM subscriptions experienced issues on the Telstra (Australia) network where new cellular communication sessions could not be established.

Affected Services

During this period, devices using the following subscriptions were affected:

• plan01s
• plan01s - Low Data Volume

Data communication via already established cellular communication sessions was not affected.

Cause

Devices using these subscriptions connect to Soracom via network partner infrastructure through local mobile network operator (MNO) networks.

We confirmed that there were no abnormalities in Soracom’s own systems during the affected period. We are currently awaiting a report from the network provider regarding the cause of the issue.

Resolution

After detecting the abnormal connectivity, Soracom updated the Status Dashboard, began an internal investigation, and escalated the issue to the network provider.

Following the network provider’s response, we confirmed that connectivity began to recover around 2026-03-10 23:32 UTC.

Future Actions

We will update this report after receiving further details from the network provider.
We will continue to strengthen coordination with the network provider and work to improve service quality.
In addition, we will continue efforts to improve the speed and accuracy of anomaly detection, as well as reduce the time required to identify suspected components and escalate issues to the network provider.
We will also continue to improve our customer communication approach.
