• 2026-10-19 Telia has carried out another network offload as part of maintenance on its IoT network, which may have affected communication for some of our NB-IoT devices.
  
  Affected devices will automatically attempt to reconnect, but repeated unsuccessful attempts can increase the time between retries. We expect normal operation to be restored within the next 24 hours.

• 2026-10-05 Telia carried out urgent maintenance on its IoT network overnight, which affected communication for some of our NB-IoT devices.
  
  The affected devices are automatically attempting to reconnect, but after repeated unsuccessful attempts, the time between connection attempts increases. We therefore expect all devices to be back online and fully recovered within the next 24 hours.
