During the same year and due to the modernization of telecommunications, Teléfonos de México integrates DIPSA in the administration of Mobile Radiotelephony. In 1981, the Secretariat of Communications and Transport (SCT) was asked for a concession to install and operate a mobile radiotelephony system known as mobile radiotelephony (telephone in the car). In 1984, the concession was obtained to operate the mobile radiotelephony service network in Mexico City, under the name of Radiomovil DIPSA S. A de C. V.
