Read Message +CMGR
Description: This command allows the application to read stored messages. The messages are read from the
memory selected by the +CPMS command. A message read with status “REC UNREAD” will be
updated in memory with the status “REC READ”.
Currently “Sent/Unsent” and “Status Report” messages are not being stored and therefore can
not be read using the +CMGR command.
