sebastianha Did anyone else find something out? I still have these "mysterious" requests.
I think I saw it in a log for my SIM manager once. It happens on the owner profile only because the SIM manager app is only installed there. This is how I could pin it down to esim related.
Also the Rethink DNS log has the SIM manager trying to contact its domain - which I blocked because I only allow whitelisted app to use internet - around the same time when the connection fails it will try to report to google.
I think the error log said something like Google play services is missing or something with attestation. But I cant remember fully anymore.
You can just try using the NoGoogle filter in Rethink DNS. But it does sometimes block domains you don't really want to have blocked. Signal uses Google as one of its provider for example, for some reason one of their domains is in that list too. Similar with a Microsoft filter.
Another list had for some reason dw.com (big news website) blocked, I think it was Tinyurl linkshortener Scam list - these lists are just not always perfect.
