is there any AT command which can reset the sim in a gsm usb modem. now i am using a MOBIDATA E66 modem. so if any can provid me the command or know similar command then please help me.

when i communicate with the sim if the connection is lost or modem is disconnected then the sim remains at that state (say i opened a menu and then got disconnected). so i need a reset command which will send the sim to the initial state.

thanks..arefin

Have you tried AT!GRESET or AT!RESET? I don't know if they are supported in your modem.

If none of them are working, use AT+CLAC to get the modem's available commands and search for some kind of RESET/RST command.

If you can't find a reset command, try turning off and on the modem radio using AT+CFUN=0 and AT+CFUN=1.
