Thanks in advance. I am using arduino and sim900 module to send my sensor data by SMS.

Now I want to check SMS left in my sim card. I'm using below code to do that.("AT+CUSD=1,\"*451#\"\r").

I want to send that response to my mobile. but i don't know how to do that. Any one please help me.

Thank you.

Read the response from the modem into a string and send it as an SMS. – SoreDakeNoKoto Dec 12 '16 at 00:31
