User Guide
Why were some of my messages
deleted from the device?
If your BlackBerry® device memory is full, your device
deletes the oldest messages from the messages list to
accommodate new ones. It does not delete saved
messages.
Why aren't all the SMS options
described appearing on my device?
Depending on your service provider plan, some SMS
message options might not be available on your
BlackBerry® device. Contact your service provider for
more information.
What are the Validity Period, Sent As,
and Network to Send Over fields in
the SMS options?
The Validity Period field specifies how long the service
center should keep your SMS messages if they cannot
be delivered to your contacts immediately. The Sent
As field specifies how to send your SMS messages. The
Network to Send Over field specifies the type of
network through which your SMS messages are sent.
