Appendix B
Some wireless service providers require 24 hours or more to
activate your wireless service. If it has been longer than your
wireless service provider's activation period, report the problem
to your wireless service provider.
Your wireless service provider may need to install your phone
number onto your SIM card. Contact your wireless service
provider to see if they can send a message to your Treo that
writes your phone number onto your SIM card.
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.
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.
For security purposes, some wireless service providers require
you to enable international calling on your account. Call your
wireless service provider for details.
Enable call waiting in the Call Preferences dialog. See the
section that begins on page 101 for details. If the problem
persists, contact your wireless service provider to confirm that
this feature is available in your area.
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.
Some wireless service providers require you to enable this
feature on your account. Call your wireless service provider to
enable blocking your Caller ID.
