Earlier quoted context omitted.
If carriers let outsiders buy cell tower data there is literally nothing you can do except switch on airplane mode.
Or, complain to the local gov't/FCC/consumer ombudsman that carriers are selling this data without consent from the consumer. Embroil them in a PR nightmare. Make it costly.
Anyway I just get cynical when I see people talk about how evil Google is and how Apple protects privacy. Every company you do business with WILL sell of your personal data and that includes mobile operators, banks and ISPs. Until that is illegal the entire discussion about privacy is irrelevant and a sham.
