Which Dell laptop models accept the DW5811e M.2 card with part number K9CNF?

The card fits Latitude models 5175, 5270, 5290, 5470, 5490, 5491, 5495, 5570, 5590, 5591, 7270, 7275, 7285, 7290, 7389, 7390, 7470, 7490 and Precision models 3510, 3530, 7510, 7530, 7730.

Does the DW5811e work in a laptop that only has an M.2 slot keyed for Wi-Fi?

The DW5811e is a WWAN module; it requires an M.2 slot wired for mobile broadband, not a Wi-Fi-only keying.

How can I confirm the DW5811e is active after installing it in a compatible Latitude or Precision?

Open Device Manager — the Sierra Wireless EM7455 modem should appear under Network adapters, and the OS will show available LTE networks.
