Accounts created on stock Pixels don’t require phone numbers.

that haven't been true since pixel 4. it just picks your phone in the background.

a burner sim, like a literal criminal, is the only way today.

Even with a burner sim, there is the International Mobile Equipment Identity (IMEI) number, which is tied to the phone, and is known to all apps with the android.permission.READ_PRIVILEGED_PHONE_STATE permission.

That can't be true? <https://grapheneos.org/faq#hardware-identifiers>

  As of Android 10, apps cannot obtain permission to access non-resettable hardware identifiers such as the serial number, MAC addresses, IMEIs/MEIDs, SIM card serial numbers and subscriber IDs. Only privileged apps included in the base system with READ_PRIVILEGED_PHONE_STATE whitelisted can access these hardware identifiers. Apps targeting Android 10 will receive a SecurityException and older apps will receive an empty value for compatibility. The currently enabled carrier-based messaging app for SMS/MMS/RCS is a special case that's given access to certain device identifiers including the IMEI. This is normally the GrapheneOS fork of AOSP Messaging but can be changed to another app by the user.

  Since these restrictions became standard, GrapheneOS only makes a small change to remove a legacy form of access to the serial number by legacy apps, which was still around for compatibility. It used to need more extensive changes such as disallowing access to the serial number but those restrictions are now standard.

I don't know however if sandboxed google play is such a privileged app.

I couldn't immediately find whether GrapheneOS grants READ_PRIVILEGED_PHONE_STATE to Google Play. It might very well be that the GrapheneOS sandbox spoofs a fake IMEI, and I do hope so.

In any case, my parent comment was meant for stock Pixels, as mentioned by armadyl further up in this thread.

> Google Play receives absolutely no special access or privileges on GrapheneOS as opposed to bypassing the app sandbox and receiving a massive amount of highly privileged access.

It doesn't mention IMEI here, but hopefully READ_PRIVILEGED_PHONE_STATE is included in "privileged access."

There is an AppStore app, I am not sure if this is the one we are talking about? <https://github.com/GrapheneOS/AppStore/blob/main/app/src/mai...>

That one lists:

  ACCESS_NETWORK_STATE
  ENFORCE_UPDATE_OWNERSHIP
  FOREGROUND_SERVICE
  FOREGROUND_SERVICE_SPECIAL_USE
  INSTALL_PACKAGES
  INTERNET
  POST_NOTIFICATIONS
  QUERY_ALL_PACKAGES
  RECEIVE_BOOT_COMPLETED
  REQUEST_DELETE_PACKAGES
  REQUEST_INSTALL_PACKAGES
  UPDATE_PACKAGES_WITHOUT_USER_ACTION

That's grapheneos's own app, separate from the play store or play services.

		True. I think this one is closer to the truth: <https://github.com/GrapheneOS/platform_packages_apps_GmsComp...> There is no READ_PRIVILEGED_PHONE_STATE mentioned there.

That's the application software side. I would assume the IMEI and IMSI are both going out to the cell network though, and I would presume that it's trivial to tie a phone number to those with how the mobile industry generally sells subscriber data to various data brokers. The only question is how permissive those data brokers are (their major constraint is how much most people become aware of this dynamic), but when dealing with a major APT like Google I'd assume they're tuned into the best ones with songs about bona fide purposes.

Are you talking about the US here? I am hoping this would be off-limits in Europe.

Its possible to set up a phone with a google account without even a sim card in it and use it as a wifi only device, so Im pretty sure what your saying is wrong.

▲ goodmythical 2 hours ago | parent | prev | next [-]

assuming the number you get hasn't previously been assigned to a google account

I've had no end of trouble registering an account on our corporate SIMs as the phone numbers (not the actual SIM cards) had been recycled as employees leave.

		So many systems cannot handle known pattern of a phone number changing. Who's decided these are imutable values? That I have only one? That it's not shared?

It still works without a SIM card, how do you explain that?
