owned by Amazon eeronew $99.99 eero Signal 4G LTE, Office has partnered Wednesday, serves as an instant backup if your internet goes down, if you have an eero subscription.

Customers plug the new eero Signal into any compatible USB-C powered eero device with Wi-Fi 6 or higher. eero Signal automatically switches to cellular when an outage occurs, then returns to Standby mode when service is restored.

This is ideal for employees who work from home, those who need security systems to stay online, or those in places that are prone to getting lost.

Since the cellular network is only used on a one-to-one basis, the subscription is cheaper than most similar 4G LTE plans. At launch, users can choose between a $99.99 annual eero Plus subscription with 10 GB of backup data or a $199.99 eero Plus 100 plan with 100 GB of data. Both offer a discounted price when you first purchase the device. Eero says the device supports several major carriers, including AT&T and Verizon, and connects to the best network at the time using a built-in multi-carrier eSIM.

Later this year, the company will also launch a 5G version of eero Signal for $199.99, and support for the device will also come with eero Business plans.
