Retrieving long messages from SIM

[abu_muttalib]

I am trying to read SMS stored on my NOKIA phone SIM using AT commands. For few messages the information is displayed in plain text and for other messages the content is not recognizable. What is the encoding /format of the message. The message retrieved is as followos:

at+cmgr=4
+CMGR: "REC READ","+919823208206",,"06/06/17,01:54:09+22",145,64,0,0,"+919823000040",145,160
05000C203220004966206D6F6E657920646F65736E742067726F77206F6E207472656573207468656E2077687920646F2062616E6B732068617665206272616E636865733F0A57687920646F6573206120726F756E642070697A7A6120636F6D6520696E20612073717561726520626F783F0A57687920646F65736E7420676C756520737469636B20746F2069747320626F74746C653F0A57687920646F2079

Is this mesage part of a long message? I have sent a message more that 160 characters long. As second part of question I wanted to know that how messages are stored on SIM.

Regards,
Abu.
