Some phone numbers don’t
appear in the SMS Lookup
Make sure the number you want is identified as a mobile
number in your Contacts list. Only mobile phone numbers and
e-mail addresses appear when you use the SMS Message
Manager Address by Last Name Lookup feature.
I can’t send SMS messages
■ Make sure SMS services are enabled on your account by
checking the SMS Preferences dialog to see if the SMS
Message Center number is on this screen. If the number is
missing, contact your wireless service provider for the SMS
Message Center number and enter it in the SMS
Preferences dialog.
Note: Receiving SMS messages does not indicate that
you have a subscription to your wireless service
provider’s SMS service. You must subscribe to this
service to send or reply to messages.
■ Verify that you are in a GSM network coverage area.
■ Make sure the destination number is correct. Some
wireless service providers require 11-digit phone numbers
for SMS messages.
I get an error message when I
send an SMS message to an
email address
Make sure you have subscribed to and enabled the SMS Email
feature. You need to get the SMS Email Center number from
your wireless service provider and enter it in the SMS
Preferences dialog. This number is different from the SMS
Message Center number you use to send messages to other
mobile phone numbers. See page 133 for details.
I get an error when sending a
long message to myself
Some wireless service providers have difficulty sending long
SMS messages to your own phone number. Try sending long
messages as a series of smaller messages instead.
I get an error when making
data calls
■ Check with your wireless service provider to make sure
that GPRS data services are enabled on your account.
■ Verify that you are in a coverage area.
The SIM Book application
won't open
Make sure your SIM card is inserted in your Treo and that
wireless mode has been on for at least 30 seconds.
My SIM Book doesn’t display
the full name and number
When a name or number is longer than will fit in the SIM Book
display, three dots appear to indicate that the entry contains
additional information. SIM Book does not truncate the actual
entry, it just does not appear on the screen.
