Verizon assures customers that this information is anonymous and can not be used to identify you. It is used for “business and marketing reports” and for targeted mobile ads. Most of the information is used internally, and some is shared with third-party companies.
If you don’t want Verizon collecting this information from your iPhone 5, then you must login to your My Verizon account and go to Verizon’s MyPrivacy section (www.verizonwireless.com/myprivacy). You can opt out of the tracking by selecting “Don’t Share my CPNI” for each mobile phone number on your account. CPNI stands for Customer Proprietary Network Information, if you are wondering.
