Do you own a Windows Phone that's connected on a AT&T account? You might not be aware of this, but you can restrict the use of personal data, should you have any privacy concerns or simply do not wish for the carrier to contact you. Customer Proprietary Network Information (or CPNI) is personal information obtained by the telecommunications company through providing a service to the customer. 

So what is this all about, and should you be bothered? AT&T collects information from you based on the services you have on your account. All carriers (and many companies) carry out the same actions to offer similar services / products to customers. If you've received a call from a company you use often who are attempting to sell you a related product, this is exactly what we're talking about.

Majority of the time the offers are exclusive to that call and may not be available online or in-stores. A mobile carrier may offer the latest Windows Phone at a discounted price, or on a plan that has 6 months subtracted from the contract. In this case, AT&T will contact you and provide said offers, but according to the privacy policy the carrier will not sell / disclose CPNI to third-parties without customer consent. You'll need to check the policies of other carriers and companies to be sure they don't sell on your information.

To keep everything in check and restrict AT&T's use of your CPNI, be sure to give the carrier a call. Should you feel the need to do so with any other company, you can also enquire to request exclusion from future marketing and promotional offers where possible.
