When a MIDlet in server mode requests a port number (identifier) to use and it is the first MIDlet to request this identifier it will be allocated. If other applications apply for the same identifier then an ￿￿￿￿￿￿￿￿￿￿￿ will be thrown when an attempt to open

￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿ is made. If a system application is using this identifier, the MIDlet will not be allocated the identifier. The port numbers allowed for this request are restricted to SMS messages. In addition, a MIDlet is not allowed to send mes- sages to certain restricted ports, a ￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿ will be thrown if this is at- tempted.

When SMS messages are received by the MIDlet, they are removed from the SIM card memory where they were stored. The storage location (inbox) for the SMS mes- sages has a capacity of up to thirty messages. If any messages are older than five days then they will be removed, from the inbox by way of a FIFO stack.

9.5 SMS Message Types

The types of messages that can be sent are TEXT or BINARY, the method of encoding the messages are defined in GSM 03.38 standard (Part 4 SMS Data Coding Scheme). Refer to section A.5.0 of JSR-120 for more information.
