Ubiquiti Launches UniFi 5G Backup as a $99 Failover Option for UniFi Gateways
Ubiquiti has introduced the UniFi 5G Backup, a compact WWAN failover device designed to keep UniFi networks online when the primary internet connection goes down. Priced at around $99 in the United States, the new device offers a simple way to add cellular backup connectivity to compatible UniFi gateway setups.
The UniFi 5G Backup is built as a small antenna-style unit that can be mounted on a wall or placed where cellular reception is strongest. Instead of requiring a separate power adapter, it connects through Ethernet and draws power via Power over Ethernet. That means users will need a PoE-capable port or injector to run it.
Once connected, the device is designed to integrate automatically into a UniFi network. A built-in status display provides quick information about the current connection, making it easier for administrators to monitor failover status without digging through settings.
The main purpose of the UniFi 5G Backup is reliability. It gives businesses, home offices, and managed networks a secondary internet path in case the main broadband, fiber, or cable connection fails. For environments where downtime can disrupt payments, remote work, security systems, or cloud services, a plug-and-play cellular backup device can be a practical addition.
In the United States, Ubiquiti is working with T-Mobile US, allowing the UniFi 5G Backup to operate without requiring users to insert a physical SIM card. The device still includes a SIM card slot, and Ubiquiti says it is not SIM-locked. It also supports eSIM, giving users more flexibility when choosing a mobile network provider.
For European availability, the technical details do not clearly indicate whether a similar carrier partnership is in place. If no preconfigured mobile profile is available, network administrators may simply need to add their own SIM or eSIM profile before using the device.
Technically, the UniFi 5G Backup uses 5G RedCap, short for reduced capability. This version of 5G is intended for devices that need dependable connectivity without requiring the highest possible speeds. As a result, performance is modest compared with full-speed 5G routers.
Ubiquiti lists speeds of up to 220 Mbps over 5G and up to 195 Mbps over LTE. That means the 5G mode is only slightly faster than LTE, but the real benefit may come from improved network efficiency, lower complexity, and the reliability advantages associated with modern 5G infrastructure.
The device is not meant to replace a primary internet connection. Instead, it is designed as an affordable backup layer for UniFi networks. If the main WAN connection fails, the network can switch to cellular connectivity and help keep essential services running.
The UniFi 5G Backup is now available through Ubiquiti’s official US store for about $99. It requires a UniFi cloud gateway or compatible gateway in the network, along with a PoE connection for power and data. For UniFi users looking for a clean, compact, and inexpensive internet failover option, this new 5G backup device could be a useful upgrade.
