Hello,

I am very interessted in your GPRS Shield and I want to use it for my weather station.
Somebody who will send for example an SMS to my Station, should get an answer SMS with some weather informations in it.

But how to get the caller id ( the telefonnumber from the calling person ) ?
Is there an AT Command?

kind regards

For the Calling income number,you can set “AT+CLIP=1” then it will show the income call number.
you can search the AT command in the datasheet by find “CLIP”.

For the SMS,you can use the AT+CMGR,you also can check it into the datasheet.
