## Updates from Telnyx
### 2026-11-03 18:19 UTC: identified
Telnyx Wireless SIMs on IMSI1 may be unable to establish new data sessions or may experience intermittent loss of data service, beginning around 15:45 UTC on November 3, 2026. This is caused by our IMSI1 partner experiencing an outage across their platform.
The platform has now been stabilised and signalling traffic is gradually being re-introduced to it to restore service.

### 2026-11-03 20:28 UTC: resolved
Data connectivity for Telnyx Wireless SIMs using IMSI1 has been restored, and we are no longer seeing elevated errors. If a device is still impacted, toggling airplane mode or rebooting may help it reattach to the network.
