Short message device for wireless telephone

摘要

A short message device for a wireless phone has a receiver to receive different types of messages, a memory (M) and a deletion device. The memory (M) stores the different types of messages and has a limited capacity. The deletion device automatically deletes one type of message when the memory (M) is full, while retaining a second type of message. A display (I) lists the different types of messages together in a single list. A filtering device changes the display (I) from a combined list of the different types of messages to a list of messages of only one type. A text entry device enters text strings when out of a short message area, and a memory (M) stores the text strings. The transmitter can then transmit the stored text strings when in the short message service area. The memory (M) stores the last message unsuccessfully sent from the phone to a wireless provider. A recall device recalls the last message unsuccessfully sent and attempts to resend the message.
