Carriers already have access to sms data since they they deliver them and there is no end-to-end encryption. Same goes for for location data(tower triangulation, might not be as precise as gps but close), call history, sms history, all data traffic use that is not encrypted, dns lookups, which ips you connect to. They might not track all that information on the backbone but they could.
