Dell DW5816e LTE M.2 WWAN Card

This Dell DW5816e is a genuine OEM mobile broadband card that adds 4G LTE connectivity to compatible Latitude and Precision laptops. It fits an M.2 slot and uses the Sierra Wireless AirPrime EM7430 module. The part number is 8XNMF. Buyers whose laptops lack an M.2 WWAN slot or who need 5G speeds cannot use this card.

Sustained mobile broadband operation

The card maintains a 4G LTE link during extended sessions such as video calls or large file transfers while on the move. Thermal output stays within the laptop's existing cooling design because the module draws power directly from the M.2 socket. No separate antenna cables are included, so the host system must already have them routed.

M.2 form factor and OEM integration

The M.2 mini-card format lets it sit flush inside supported chassis including Latitude 5175, 7275, 7285, 7390, 7490 and Precision 7510, 7530, 7730 models. Installation uses the laptop's single mounting screw and existing antenna connectors. Systems without factory WWAN antennas or a compatible BIOS whitelist will not recognise the card.

Questions about this item

How much power does the DW5816e LTE card draw when the laptop runs all day?

The Dell DW5816e is a low-power M.2 WWAN module designed for mobile broadband; typical LTE cards in this class draw well under 5 W while active and milliwatts when idle, so all-day use adds minimal heat to the system.

What must my laptop already have for this card to work?

An available M.2 Key B slot wired for WWAN, an active nano-SIM with a data plan, and internal LTE antenna cables connected to the card's U.FL ports.

Will the DW5816e fit and function in my older Latitude E7270?

Yes — the E7270 is listed among the compatible Dell models, so the card fits the M.2 WWAN slot and works with the laptop's existing antenna wiring and BIOS.
