All of this info comes right from a letter from T-Mobile’s CEO.
Experian is a credit bureau. They maintain records about your credit cards, including the applications that you might fill out with your name, birthdate, Social Security number, and mother’s maiden name.
T-Mobile uses Experian to process credit applications for new customers.
All of the T-Mobile customer application records from September 2013 through September 2015 were stolen from Experian.
Affected customers can get 2 years of free credit monitoring.
And who is going to monitor your credit for you? Experian.
Fortunately, this particular breach doesn’t apply to me. Because I think I’d pass on that offer.
