T-Mobile takes on US banking market
T-Mobile is bidding to shake up the US banking market with a new service which offers current account-style features to the country's millions of underbanked.
T-Mobile US is stepping beyond cellphones and offering payment cards in the latest effort to differentiate its service from bigger rivals.
The No. 4 U.S. mobile provider said it is offering a Visa card with banking features and a smartphone money management application with reduced-fee or zero-cost services for T-Mobile wireless customers.
The company, which has gained attention with promises of more flexible and cheaper cellphone services, is hoping to attract a similar following in personal finance.
