Glad you asked @rhysowen! Cellular Backup is included with a Protect Plus Plan. The Protect Plus Plan subscription is required for this feature to be obtained. Without Cellular Backup, or Protect Plus Subscription, your Alarm will only have battery backup. If you are not subscribed and are without the Cellular Backup option, we’ve seen neighbors look into wifi routers that feature battery backups, for any power outage instances. Check out our help center article about Cellular Backup, for more information. I hope this helps!
