T-Mobile ramps advertising ambitions - Mobile World Live 10 MAR 2021 T-Mobile US revealed plans to launch a new advertising programme which will allow it to share subscriber data with third parties, following rivals in a bid to capitalise on interest in targeted marketing. An operator representative told Mobile World Live it will begin collecting information including “broadband usage data and app data” from T-Mobile and legacy Sprint customers on 26 April, “to allow us and third parties to provide interest-based ads”. The representative added it is notifying customers and “made it easy for them to opt out” of sharing their information through their account settings.
