Sim tool kit.  Page (126 - 151).

I have read this doc.

But I need some clear explanation with example.

Do have you a serial link to module.
if so at Terminal you send command ATI and module replies with
SIMCOM_Ltd
SIMCOM_SIM300C
Revision: 1008B09SIM300CM32_SPANSION

if you have a old serial modem (you don't need to connect to phone line) you connect it to your pc serial port and try using HyperTermial. and see responces you get back.

A example about text mode for u:

AT
OK
AT+CMGF=1
OK
AT+CMGW="+85291234567"
> A simple demo of SMS text messaging.
+CMGW: 1
OK
AT+CMSS=1
+CMSS: 20
OK

Here is a description of what is done in the above example:
    + Line 1: "AT" is sent to the GSM / GPRS modem to test the connection. The GSM / GPRS modem sends back the result code "OK" (line 2), which means the connection between the HyperTerminal program and the GSM / GPRS modem works fine.
    + Line 3: The AT command +CMGF is used to instruct the GSM / GPRS modem to operate in SMS text mode. The result code "OK" is returned (line 4), which indicates the command line "AT+CMGF=1" has been executed successfully. If the result code "ERROR" is returned, it is likely that the GSM / GPRS modem does not support the SMS text mode. To confirm, type "AT+CMGF=?" in the HyperTerminal program. If the response is "+CMGF: (0,1)" (0=PDU mode and 1=text mode), then SMS text mode is supported. If the response is "+CMGF: (0)", then SMS text mode is not supported.
    + Line 5 and 6: The AT command +CMGW is used to write an SMS text message to the message storage of the GSM / GPRS modem. "+85..." is the recipient mobile phone number. After typing the recipient mobile phone number, you should press the Enter button of the keyboard. The GSM / GPRS modem will then return a prompt "> " and you can start typing the SMS text message "A simple demo of SMS text messaging.". When finished, press Ctrl+z of the keyboard.
    + Line 7: "+CMGW: 1" tells us that the index assigned to the SMS text message is 1. It indicates the location of the SMS text message in the message storage.
    + Line 9: The result code "OK" indicates the execution of the AT command +CMGW is successful.
    + Line 10: The AT command +CMSS is used to send the SMS text message from the message storage of the GSM / GPRS modem. "1" is the index of the SMS text message obtained from line 7.
    + Line 11: "+CMSS: 20" tells us that the reference number assigned to the SMS text message is 20.
    + Line 13: The result code "OK" indicates the execution of the AT command +CMSS is successful.

CMGF=1 (text mode)

CMGF=0 (hexmode)

This command also works for sim toolkit (STK).

I dont need help about simply sending, receiving, or deleting the SMS.

Anyway,thanks for your trying.
