● Is the SIM is inserted correctly? Remove and reinsert the

	SIM in your HP iPAQ.

	in a closed area. Move to an open space or closer to a
	window. For more information, see Check connection and
	signal strength on page 29.
	● Is the network set up correctly? If necessary, try to select
	your network manually.
	● Have you activated the Fixed Dialing, Call
	Forwarding, and Call Barring functions? If yes,
	deactivate them temporarily.
	● Are you using two SIM cards, one with the Enable SIM
	PIN function activated and the other with the Enable SIM
	PIN function deactivated? If yes, deactivate the Enable
	SIM PIN function temporarily. For more information,
	see Change the SIM PIN on page 33.
	● Is your HP iPAQ switched to the Flight mode? If yes, turn
	it off. For more information, see Use Wireless Manager
	on page 65.
