I figured you were trolling but gave you the benefit of the doubt right up until you mentioned “all credit reporting agencies”, in Belgium. There are no credit bureaus in Belgium, only a central bank which (unlike US credit bureaus) is public sector and not interested in grabbing data for profit, or in obtaining any data it’s not legally required to obtain.
Nice try though.
But FYI, your assumption would be wrong even in the US as well. Request your credit report from whichever credit bureau you believe is buying location data from your mobile phone provider. Notice the realtime location data is not on that report. Then go to your local small claims court and spend ~$100 to open a lawsuit against them for $1k (+~100 in court costs). Bring to court proof that they acquired your realtime CDMA/GSM location data, a copy of your credit report showing it’s not there, and a copy of the federal law requiring that consumer credit reports are complete when sent to the subject of the report (yourself). It might be the easiest $1k you’ve earned. You don’t have to prove actual damages either because the statute specifies $1k per violation. If you can catch all three credit bureaus doing what you claim, that’s an easy $3k. You can even hit all 3 in one case. Good luck!
BTW, I don’t put much stock into what you’re saying at this point but I am curious about the claim that phone providers are sharing sensitive personal info with Visa and Mastercard. Cardholders are just a number to visa & mc. Visa & MC do not even typically know the names of card holders. Exceptionally, if you buy airfare using a credit card, then the airline reveals the name of the passenger to the credit card company. Though to store that name as the account holder is ad hoc because they would have to make the assumption that the passenger and the buyer are the same person.
