Hello there, i tried to search in matrix logs and in the FAQ under "What kind of connections do the OS and bundled apps make by default?" but i haven't found what i was looking for.

I get that IMSService is/could be used to download carriers configs from 3gppnetwork.org (and others idk?) for services such as volte and others but since a while i have been wondering what kind of data do it send to the second domain, a google firebase one, once i tried to look at the source code but i haven't found it on graphene os github so i gave up, now i searched again and not sure if i understand right but is the app is pulled from google rom ? It's not on github, I went to the aosp repo and found it there, while i don't understand what the code is doing, forgive my ignorance, i can read stuff about FirebaseMessaging which seem related, so i was wondering what data is sent out to google or for which feature, i can see that it's not much data and rarely, but i was curious about it since a while. Thanks for your work!

    randomname changed the title to about imsservice and connection to google domain .

    randomname there was a discussion related to this a while back. Perhaps it may help answer some of your questions, or at the very least give you a tad bit more insight.

    EDIT: note from flawedworld. this tweet has nothing to do with ImsService.

    Furthermore, as time permits, someone with more knowledge on this may be able to assist you better.

    randomname ImsService is the IMS stack on 6th generation Pixel devices. It's used for WiFi Calling and VoLTE, i.e anything to do with IMS, it gets handled by that. It just talks to your carrier to actually do that functionality, since that's done over TCP/IP.
