SAN ANTONIO, Texas: US telco AT&T has launched an advertising campaign to let consumers know it is ditching the Cingular Wireless brand and marketing the largest US carrier as "Wireless from AT&T".

The move follows completion of its acquisition of smaller rival BellSouth, giving it full control of the Cingular and its 58 million customers. It was previously a joint venture.

AT&T says its will save around $2.8 billion (€2.16bn; £1.42bn) a year from dissolving the BellSouth and Cingular names and advertising everything under it own moniker.
