The radiotelephone is bidirectionally coupled through a wireless interface to a network operating in accordance with a wireless communication protocol. A method comprises steps of (a) composing a text message in the radiotelephone for transmission to the network, (b) before transmitting the text message, entering information into the radiotelephone for specifying a state of at least one protocol element of the wireless communication protocol for placing the wireless communication protocol into a selected configuration, and (c) transmitting the previously composed text message from the radiotelephone to the network using the selected configuration. The user may also specify that a SMS message transmitted from the radiotelephone be converted to another message type (e.g., a facsimile message, a page message, or an electronic mail message) by the network, before being forwarded by the network. Another method of the invention includes the steps of (a) providing in the memory a plurality of sets of variables, each variable relating to a respective protocol element, (b) composing a text message in the radiotelephone for transmission to the network, (c) entering information into the radiotelephone for specifying a value for a selected variable of one of the sets of variables, (d) selecting one of the sets of variables for placing the wireless communication protocol into a selected configuration, and (e) transmitting the text message from the mobile terminal to the network using the selected configuration.
