The Department of Telecommunications (DoT) has cautioned users about fake international calls displaying the +91 prefix, urging vigilance against telecom-related cyber fraud.
India's Department of Telecommunications (DoT) warned users that calls displaying +91 as "international" are a scam, since +91 is India's country code and real international calls always show the originating country's code.
