Triple SIM Router with Auto-Carrier Detect and Select

The BEC MX-221P is a high-performance 4G/LTE Router integrating Triple-SIMs interfaces with Auto-Carrier Detect and Select, Dual Gigabit Ethernet and Power over Ethernet (PoE). Unique to BEC, the MX-221P automatically detects and measures the signal level and quality of your connection and selects the carrier priority and failover order. Alternatively,  you can create your own pre-defined selection based on preference or rate plans.

The MX-221P is highly configurable supporting seamless integration into any network deployment while providing advanced functionality such as Automatic Failover, IP Passthrough, Load Balancing, Dynamic Routing, VPN Termination, and VRRP. A versatile and feature-rich platform, the BEC MX-221P is a best-in-class solution for organizations seeking a rapidly deployable, highly scalable solution combining enterprise-grade router functionality with flexible LTE connectivity at a competitive price.
