When the receiver of the text message tries to check the identity of the sender, they can only see the changed version that the fraudster is willing to show.

Text spoofing is carried out by using an SMS gateway software by which the texts are sent in bulk before masking the identity of the sender. The scammers are known to impersonate renowned companies with inadequate safeguards or even have their SMS gateways in place.
