Supl.vodafone.com = supl.google.com 😱

supl.vodafone.com is an alias for supl.google.com.

@SkewedZeppelin Thank you for your very important and valuable hint!!!

@SkewedZeppelin

It must also be noted that SUPL is overridden by the carrier and when placing an emergency call.

What exactly do you mean by that? I would like to understand a bit of the background and context. (Maybe you also have a link to the topic?).

@LibrePhoner

Would it be possible to create a possibility in the Android settings that you as a user can define SUPL_HOST yourself? I myself would then want to enter localhost. I would prefer that than Vodafone. How do Graphene, Calyx, Divest and /e/ solve this problem?

Graphene has recently come up with a solution for this:

Changes since the 2023011000 release:

• don’t send IMSI / Phone number to SUPL server when SUPL is enabled (note: using SUPL is always an optional choice in APN configuration on GrapheneOS, unlike AOSP and the stock OS)

That sounds optimal to me.

So you can simply turn off A-GPS as a normal user!

And if you do leave it enabled, Google will no longer receive your IMSI number. And that’s what it’s all about in the end, isn’t it?

I understand that this way, you can use the advantages of A-GPS and nevertheless Google is completely outside and the privacy is guaranteed. Or is there a catch? Maybe because of your comment with the “overridden”?
