Sprint notified customers that unless you opt-out, Sprint reserves the right to share your private calling data with third party marketers. Sprint hires these companies to market other Sprint services to you.
The data includes:
• whom, where, when, and for how long you call;
• what products and services you buy;
• how those products and services are configured;
• what details are contained in your bill.
You can call 1-(800)-865-7786 to opt out. Of course, that number is nowhere on the written notice, as Sprint seems to prefer the efficiency of you snail-mailing one in. Notice scan inside.
