Ubiquiti U-LTE-BACKUP-PRO | UniFi LTE Backup Pro

An LTE failover device for UniFi gateways that cuts over to mobile data automatically when your primary internet connection drops.

Why this one

• Failover is handled by the device itself, so your gateway switches to LTE without manual intervention — useful when the connection you're protecting is carrying security cameras or access control.
• It integrates directly with UniFi Network, so failover status and data usage appear in the same dashboard you're already managing everything else from.
• Bring-your-own nano-SIM means you choose your own AT&T data plan and aren't locked into a bundled arrangement you didn't ask for.

Good fit if you're running a UniFi gateway at a site where a dropped internet connection causes a real problem — a retail location, a small office, or anywhere with UniFi Protect cameras that need to keep recording.

Worth considering something else if you're not already on a UniFi gateway, as this device integrates with UniFi Network and won't function as a standalone failover unit on third-party hardware.

What you'll also need

A compatible UniFi gateway (such as the UDM-PRO, UCG-MAX, or UXG-PRO), an AT&T nano-SIM with an active data plan, and a PoE switch or injector to power the unit if your gateway doesn't provide a dedicated port for it.
