T-Mobile can keep Nest Secure online if your WiFi fails

It’s the exclusive cellular backup provider for the Nest alarm system.

In September, Nest released its Secure alarm system, complete with motion and door sensors and an app that lets you manage the system from anywhere. But arming the alarm through your phone or receiving alerts that motion has been detected in your home requires the Nest system to be actively connected to WiFi. If your internet service goes down or your home network stops working, however, you won't get those alerts or be able to access your system through Nest's app. That's why Nest has worked cellular backup into the Secure system and T-Mobile announced today that it's the exclusive cellular provider for Nest Secure.

Through T-Mobile, you'll be able to get the full Nest Secure pack, including the Nest Guard base, two Nest Detect door/window sensors and two Nest Tag key fobs that let you arm or disable the alarm system without having to mess with a passcode. It also comes with a Nest Cam Indoor security camera with intelligent alerts provided through Nest Aware. And, of course, it comes with cellular backup that will kick in whenever your WiFi becomes inaccessible.

The T-Mobile Nest plan costs $240 down and $10 per month (for 24 months) once a $5 monthly credit is applied. That credit is only available for a limited time, according to T-Mobile, and it's unclear how long the deal will last. If you cancel your wireless service plan before the 24 months are up, though, you'll have to pay the remaining balance. If you want to buy the setup without T-Mobile's service, you can get it for $698, which is what it would cost through Nest.

The Nest security pack will be available in T-Mobile stores starting November 10th.
