B.1.5 SMS Menu

SMS (Short Message Service) functions are accessed through the SMS menu. For modems that support a SIM card, the SIM initialization typically takes longer than the network ini- tialization, resulting in a noticeable delay before the SMS functions become available.

B.1.5.1 New

Tapping on the New button opens a dialog for sending a new SMS message. The recipient's phone number (to be entered in the To: field) can consist of the digits 0 through 9, as well as the * and # characters, optionally preceded by one + character, indicating an international number (i.e. the country code follows immediately after the + character).

By checking the Store message in Outbox field a new message can be stored in the Outbox before being sent. If no storage space is available, or the modem does not support the storage of outgoing messages, then this checkbox is disabled.

B.1.5.2 Inbox

Tapping on the Inbox button opens the list of received messages. Reading 50 messages, for example, from the SIM can take about 30 seconds. By default the list of messages is sorted with the most recently received message first. The list can be sorted by any other column by clicking on the corresponding column heading. Clicking the same column heading twice re- verses the sort order. Pressing any letter or digit moves the highlight to the next message whose address begins with that letter or number.
