Support for third-party SIM cards. Avoid internet downtime and productivity losses by adding a UniFi LTE Pro to your existing UniFi network. The UniFi LTE Pro provides backup cellular internet connectivity to ensure that your UniFi WAN network is always operational. This model operates in the EU region and supports European LTE and WCDMA bands. It features a Nano-SIM card slot for your own card. Simply insert the Nano-SIM, connect to any switch port in your corporate network, and activate the device. For easy monitoring, the 1.5-inch display shows status information, such as the failover status: ready or active. You can also track your LTE data usage during a failover for the current billing period. The UniFi LTE offers excellent coverage with its internal high-performance antenna. If you need greater LTE coverage and performance, you can connect an optional high-gain antenna to the RP-SMA antenna port for a stronger signal. The external antenna can be mounted outdoors for optimal positioning.
