Sprint shared the following statement with FOX4:

Because Sprint takes this matter, and all matters involving our customers’ privacy, very seriously, in addition to the initial customer notification, Sprint is taking the extra step of separately sending letters to impacted customers to remind them to update their existing PINs and that a dedicated Care Team has been established for assistance. As a precautionary measure, we have also provided information on tools and resources that will help our customers safeguard their personal information.
