Sandboxed Google Framework access to Identifying data?

Pflanzgarten

I'm a privacy newbie and searched for my question but couldn't find an answer. I want to dump Google and my mobile number and use an anonymously purchased SIM to run VOIP on a anonymously purchased new phone. I want to port my legacy number to Google Voice because it's cheap and the number and my google account are already compromised. After the transition is complete I would stop using Voice and the legacy number completely.

If I make a new GOS profile and run sandboxed Google framework, services and store and install Google Voice in that profile will Google have any access to any personally identifying information from the phone like the Android Identifier, IMSI, SIM, Device IP Address, IMEI or MAC address?

Pflanzgarten Sandbox play service has no access to anything, and according to a GrapheneOS developer, if you don't use a sim card you can be anonymous.
