I'm not sure if there is such a AT command but anyway you can find all the sim900 AT command in the link below. https://www.robotshop.com/media/files/pdf/command-manual-im140318007.pdf

After you receive the SMS text, you need to parse the message to separate the caller_ID, date & time, and the actual message body.

There are many guides to parsing SMS messages

There are many examples out there - both in this forum and others.
The goal is to enable SMS reception, and accept +CMT messages.

Google is your friend... that’s how I learned, along with hours of experimentation & practice.

Suggestion: When you find examples, DON’T use Strings —- use C-strings to avoid unstable operation with a small memory processor like Arduino.

c-strings are a learning curve, but offer performance and flexibility benefits when you’re handling character strings.
