My laptop has a SIM slot but no "Cellular" in settings - why?

Either your configuration has no module installed (a slot with no module behind it is common), or the module sits without a driver. Device Manager settles it: an unknown device with a modem's Hardware ID means the second case.

Which driver does my LTE module need?

The modules are made by Quectel, Fibocom and Sierra Wireless, but take the package from your laptop model's support line - it is built with the right settings.

The modem works but the connection keeps dropping - will a driver help?

It may: updating the module's firmware and driver is the first remedy for drops. The second is antennas and coverage, where no driver can help.

Modems & mobile broadband drivers

WWAN drivers serve the cellular modems built into laptops - LTE and 5G modules by Quectel, Fibocom and Sierra Wireless - plus USB modems. Without the driver, the SIM card in your laptop simply does not exist for Windows. The packages here are from official sources.

About modems & mobile broadband drivers

A WWAN module is a rare beast: even within one laptop model it ships only in some configurations, and after a Windows reinstall its driver has to be hunted down by hand. The telltale signs - an unknown device in Device Manager with a SIM inserted, and no "Cellular" section in network settings at all.

The package is found by the module's Hardware ID; for business laptops (ThinkPad, Latitude, EliteBook) it lives in the support section of the exact model.
