Not sure how they are planning to achieve that.<p>The only edge they <i>potentially</i> have is access to location data without a possible opt-out. Everything else is behind HTTPS, so impossible for them to track. Facebook can pull it off because people stay within Facebook's services (FB, Instagram, WhatsApp, etc). The carriers don't have any kind of compelling service users would spend all day in.<p>This will fail miserably, and I'm very happy about that.
