The Connected Solutions Group CSG-m212 is a WiFi 6 LTE Cat 12 business router certified on Verizon, AT&T, and T-Mobile, engineered for small and medium businesses, MSPs, and distributed teams that need reliable primary or failover internet connectivity with built-in battery backup, dual-SIM redundancy, and enterprise-grade security right out of the box. Supporting LTE Bands 2, 4, 5, 13, 48, and 66 across all three major U.S. carrier networks, the CSG-m212 delivers up to 600 Mbps cellular downlink through a WiFi 6 dual-band access point supporting up to 85 connected devices, and keeps your network live for up to 8 hours on its removable 5,900mAh battery when commercial power is unavailable. Paired with an ISPTek SIM card data plan on Verizon, AT&T, or T-Mobile, it becomes a complete primary or backup connectivity solution deployable in minutes.

What It Does & Key Features:

  • LTE Cat 12 — Up to 600 Mbps Downlink: Cat 12 delivers three-carrier aggregation and 4×4 MIMO across Bands 2, 4, 5, 13, 48, and 66 for peak downlink throughput up to 600 Mbps and uplink up to 150 Mbps — certified across Verizon, AT&T, and T-Mobile to provide that throughput on whichever network delivers the strongest signal at your deployment site.
  • WiFi 6 Dual-Band — Up to 3 Gbps Combined Wireless: 802.11ax WiFi 6 with OFDMA and MU-MIMO delivers up to 574 Mbps on 2.4 GHz and up to 2,402 Mbps on 5 GHz — distributing cellular bandwidth efficiently across up to 85 simultaneous connected devices without the performance degradation that affects older WiFi standards under dense-client load.
  • Dual Nano-SIM with Automatic Failover — Zero-Downtime Redundancy: Two Nano-SIM slots with automatic failover keep your connection live if one SIM or carrier link drops — no manual intervention, no reconfiguration required. Load two different carrier SIMs to ensure continuous connectivity regardless of individual network events.
  • 5,900mAh Removable Battery — 8 Hours Untethered: The removable 5,900mAh lithium battery delivers up to 8 hours of runtime under normal operating load — providing built-in UPS-style backup during commercial power outages and making the CSG-m212 fully portable for field deployments, pop-up events, and temporary office setups without requiring any external power infrastructure.
  • LAN/WAN Switchable Gigabit Ethernet — Flexible Wired Connectivity: Two Gigabit Ethernet ports configurable as LAN or WAN deliver flexible wired integration — connect downstream switches and wired devices via LAN, or designate one port as a wired WAN input when a secondary ISP connection is available, with LTE automatically serving as the backup path.
  • OpenWrt Firmware with CSG View Cloud Portal: The CSG-m212 runs OpenWrt-based firmware managed remotely through the CSG View cloud portal for configuration, real-time data usage monitoring, and batch device management across multiple deployed units — giving MSPs and IT administrators full remote visibility and control without on-site access.
  • AdGuard Home & VPN Security — Enterprise Protection Built In: Integrated AdGuard Home provides network-level ad and tracker blocking for all connected devices without additional licensing, while built-in VPN support secures all traffic from the WAN link inward — delivering enterprise-grade network security at the router level, out of the box.
  • USB-A Port with Network Storage & Charging: The USB-A port supports external USB drives and TF card adapters for network-shared folder access across connected devices, plus 5V/1A output for charging connected accessories — adding practical utility for field installations and temporary deployments beyond pure routing.

Certified on Verizon, AT&T & T-Mobile:

The CSG-m212 carries official certification on Verizon, AT&T, and T-Mobile. ISPTek activates SIM card data plans on all three carriers — insert your ISPTek SIM into either slot, power on the CSG-m212, and your certified LTE connection is live the same day on whichever network best serves your location.

  • Verizon Certified — Band 13 Low-Band & Full Mid-Band Coverage: Certified on Verizon’s network with Band 13 (700 MHz) for extended-range low-band coverage and deep building penetration, alongside Bands 2, 4, and 66 for three-carrier aggregation at peak 600 Mbps downlink in metro and suburban markets. Activate on Verizon with an ISPTek SIM card data plan for certified LTE coverage across Verizon’s nationwide footprint.
  • AT&T Certified — Band 5 Low-Band & Mid-Band Data Speeds: Certified on AT&T’s network with Band 5 (850 MHz) for reliable low-band reach in rural and suburban areas, plus Bands 2, 4, and 66 for high-throughput mid-band LTE in dense markets. ISPTek’s AT&T plans deliver business-grade data with static IP options and pooling for multi-site deployments on AT&T’s network.
  • T-Mobile Certified — Broad National Coverage on Bands 2, 4, and 66: Certified on T-Mobile’s network with Bands 2 (1900 MHz), 4 (1700 MHz), and 66 (1700 MHz) delivering reliable LTE coverage across T-Mobile’s national footprint, including suburban and rural locations where T-Mobile’s mid-band frequencies provide consistent data performance.
  • Band 48 CBRS — Private Network Compatibility: Support for Band 48 (3500 MHz CBRS spectrum) enables deployment within private on-premise LTE networks alongside public carrier connectivity — making the CSG-m212 a compatible endpoint for enterprises building CBRS-based private wireless infrastructure in facilities, warehouses, and campuses.

Enhanced with ISPTek’s Cellular SIM Card Data Plans:

  • Public Static IP Addresses: Assign a fixed IP to your LTE WAN link for VPN tunnels, remote device access, SCADA systems, and hosted services — available on Verizon, AT&T, and T-Mobile plans through ISPTek, fully compatible with the CSG-m212’s built-in VPN capability.
  • Data Pooling Across Devices: Share one monthly data pool across multiple CSG-m212 units and SIM-equipped devices — reducing cost and simplifying billing when managing connectivity across 5 or 50 business locations on a single ISPTek account.
  • Over 12 Custom Plans: Choose from light monitoring tiers to fully unlimited throughput plans on Verizon, AT&T, or T-Mobile with no throttling or overage surprises — matched to your actual usage and the carrier with the best coverage at each site.
  • No Activation or Cancellation Fees: Start, change, or stop service at any time with zero setup costs or termination penalties — ideal for short-term project deployments, seasonal businesses, and event connectivity that doesn’t fit into long-term contracts.
  • Zero Touch Advanced Security: Automated security provisioning protects your cellular WAN from day one without manual configuration — complementing the CSG-m212’s built-in AdGuard Home and VPN features for defense in depth across both the network edge and the WAN link.

Who Benefits?

  • Small & Medium Businesses: The CSG-m212 delivers a complete primary or failover LTE connection with WiFi 6 for up to 85 devices, built-in battery backup, and remote cloud management — without the complexity or cost of enterprise-tier hardware.
