Lenovo ThinkPad Fibocom L860-GL-16 CAT16 4G LTE WWAN M.2 Cellular Modem Module

The Lenovo 4XC1K20995 is an M.2 cellular modem module that equips compatible ThinkPad laptops with Fibocom L860-GL-16 CAT16 4G LTE WWAN connectivity. The card slips into an open M.2 slot and integrates with the system firmware, so there is no need for external dongles, cables, or additional adapters. Once installed, the laptop can tap into 4G LTE networks and reach gigabit-level data rates when carrier conditions allow, giving you a reliable link for cloud apps, large file transfers, and real-time collaboration.

This built-in approach is ideal for professionals who work on the move, students who study in locations where Wi-Fi is unpredictable, and field teams who need quick access to corporate resources from remote sites. Because the connection comes from inside the system, you can open the lid and be online without searching for a public hotspot, and the USB ports remain free for other peripherals. When LTE coverage weakens, the module automatically falls back to earlier mobile technologies that the carrier supports, helping you stay productive on highways, in rural areas, or at client sites with limited infrastructure.

• CAT16 LTE mobile broadband that supports gigabit-level throughput
• Installs directly into an available M.2 slot with no extra cables needed
• Provides Gigabit Ethernet over cellular for fast, consistent data transfer
• Automatic fallback to earlier network standards when LTE is unavailable
• Ideal for travel, remote work, and any environment where Wi-Fi is unreliable
