One more thing to double-check: is the SIM slot under the battery, and
if so is the battery inserted and correctly seated?  My laptop (an HP,
not a dell) has some kind of BIOS interlock so that when the battery is
removed (or poorly secured) it will rfkill the WWAN card automatically
to prevent SIM hotswapping.
