Dell DW5811e 4G LTE M.2 WWAN Card

This genuine Dell OEM module adds 4G LTE mobile broadband to compatible Latitude and Precision laptops. It installs in an M.2 slot and uses the Sierra Wireless AirPrime EM7455 modem. The card is designed for professionals who need cellular connectivity away from Wi-Fi networks. Part number MR7VT identifies the exact Dell service part.

Upgrade from no WWAN or failed module

If your laptop shipped without a WWAN card or the original module has stopped registering on the network, this card restores factory cellular capability. The jump is worth it when you travel frequently and cannot rely on hotspot tethering or public Wi-Fi. It fits the listed Latitude 5175, 5280, 5480, 5580, 7280, 7480, 7490, 7290, 7390 and Precision 7520, 7720, 7530 models among others.

Sustained LTE operation in a laptop slot

The module draws power directly from the M.2 socket and is cooled by the laptop's internal thermal solution. During long downloads or video calls it maintains the LTE link without throttling, provided the host chassis airflow is adequate. Buyers who need dual-SIM failover or 5G speeds should look elsewhere, as this card supports a single SIM and LTE categories only.
