My Treo won't register to the
network
■ You are probably outside a network coverage area. Try
using another GSM phone to verify whether coverage is
available in your current location.
■ If coverage is available in your location, try your SIM card in
another GSM phone. If it still doesn’t work, your SIM card
may be malfunctioning. Contact your wireless service
provider for another SIM card.
■ Turn off the wireless mode on your communicator, and
then turn it on again. If a dialog appears asking if you want
to search for a network, tap Yes.
I tried dialing a phone number,
but my Treo just beeps at me
■ Make sure you dialed the correct number.
■ Wait a few minutes and try again. If the network is very
busy, calls cannot connect.
■ Verify that you are in a network coverage area and then
move a few yards away and try the call again. If you are in
a weak coverage area (1 bar of signal strength or less), you
may not be able to complete calls even though you are
registered to the network.
I can't dial international
numbers
For security purposes, some wireless service providers require
you to enable international calling on your account. Call your
wireless service provider for details.
Call waiting doesn’t work Enable call waiting in the Call Preferences dialog. See the
section that begins on page 97 for details. If the problem
persists, contact your wireless service provider to confirm that
this feature is available in your area.
Call forwarding doesn't work For security purposes, most wireless service providers require
you to enable this feature on your account even though there
is usually no extra charge. Call your wireless service provider to
enable call forwarding.
Caller ID blocking for my
outgoing calls doesn't work
Some wireless service providers require you to enable this
feature on your account. Call your wireless service provider to
enable blocking your Caller ID.
Some incoming caller’s
names don’t appear in Call
History
■ Find out if a caller has blocked their Caller ID.
■ Call History does not show names for records you marked
hidden in your Contacts list.
