Not as of yet - though that is one option being discussed between SpaceX and potential customers. Point is that Starlink isn’t physically capable of “tracking all the cell phones” as E. Pluribus there seems to think it is.
Starlink uses Ku band and V band for terminal links thats 18ghz and 40ghz. Cellphones use UHF, L band and some S band particularly 5G and iridium & globalstar sat phones use Lband and Sband respectively. There’s no what via physics that starlinm could track a conventional or even a sat phone. Sorry thats just tinfoil nuttery.
Iridium absolutely tracts the position of it’s mobile phones it must do so for billing, compliance with national frequency and security restrictions and also as a function of the spotbeam and handoff requirements of the coms link itself. Globalstar also must track the location of it’s phones for the same reasons. I’m a operations and field geologist I use iridium on the regular as well as inmarsat and globalstar spot 3 beacon for tracking and SOS beacon. I’m hoping that spacex will come up with a bgan like terminal that can hookup to starlink at anything above 50kbps which is where voip, email,sms, and slow scan 10fps vidcoms is possible for moral reason back to home office.
