Amazon Eero Signal review: 4G LTE internet backup for your Eero mesh network

Amazon has added the $99 Eero Signal to its Eero lineup, bringing 4G LTE backup to compatible Eero mesh systems.

Setup is simple through the Eero app, and cellular backup service is available via Eero Plus plans with different data caps.

The device offers Eero users a relatively low-cost way to keep home internet running during broadband outages.

It is especially useful in areas where broadband service is unreliable.
