nagajothisaravanan very clear explanation.i bought same type modem,with 12v power supply connected. using usb to ttl converter,i can not communicated with the modem using putty in all baud rate. what is the default buad rate of the modem. please reply waiting for your reply. thanks.

Hey thanks for your comment

[@technolabcreation]

The default baud rate of sim 900a is 115200

Hello, friend, is it possible to send an AT Command via SMS to Restart the SimCard connection? If so, what is that command?

[@technolabcreation]

To restart the SIM card connection, you might use one of the following AT commands: AT+CFUN=1,1: This command resets the GSM module, which effectively restarts the SIM card connection. AT+CREG=0 followed by AT+CREG=1: This disables and then re-enables the network registration, which can restart the SIM card connection.
