Incident
Report for Twilio
Resolved
The issue with Super SIM Devices connectivity has been resolved and services are operating normally at this time.
Monitoring
We are now seeing recovery of the previously reported connectivity issue. We are continuing to monitor for service stability. We will provide another update in 2 hours or as soon as more information becomes available.
Update
Beginning at 00:45 UTC, we observed ~35% of active data sessions on Super SIM being dropped. Devices that attempted to reconnect immediately after losing connectivity should have been able to successfully reconnect to the network using a secondary IMSI. Currently, we are still monitoring the situation as approximately 15% of devices may still experience connectivity issues. These devices might encounter poor data connection or have short-lived sessions and as such are not able to successfully perform an IMSI switching procedure. Our engineering team is actively working alongside the affected network provider to resolve the issue as quickly as possible. In the meantime, we kindly suggest that customers reset the connectivity through the console if they notice that some of their SIM cards are still experiencing issues. This can often help re-establish a stable connection for the affected devices. We will provide another update in 4 hours or sooner once more information becomes available.
