Monitoring

Currently, based on our monitoring systems, all devices which were affected by the data connectivity issues on AT&T should have a re-established data connection. Our engineering team is actively working alongside the affected network provider to continue monitoring the issue. 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 2 hours or sooner as soon as we have more information available.
