Yes, it's a scam. There is NO free money. The telephone number is most likely spoofed (fake). The scammers could be calling/texting you from anywhere in the world. They will try to steal all the money they can from you. That is the reality.

This is a long running scam.  Please pay attention.   There is no Grant Dept.
