In the Supreme Court ruling, the Court specifically addressed the issue that the purpose for which the information was shared was relevant to the establishment of a privacy interest.
Cell phone information is shared with the cell tower operators as a necessary function of the cellular system: your phone wont work if the towers do not know how to route the data to you. You maintain a 4th amendment privacy interest in the information, even though it is shared with third parties.
Also the SCOTUS has stated:
From Carpenter v. United States (2018)
(1) A majority of the Court has already recognized that individuals have a reasonable expectation of privacy in the whole of their physical movements.
The problem is that the purpose for which the government is recording in public is to track you which violates the 4th Amendment in multiple ways. Ergo, while you have no expectation of privacy in the public with regard to observation of your person, your movements and any databased data on your persons in aggregate, do.
