I can't really use my mobile connection. After a connection to the cell network is established, it gets interrupted after a few seconds. It's not just the mobile internet but the connection to the network itself. I am new to GOS and dont really know how to gather information for debugging. I played around with the connection settings but nothing seems to help. Does anybody encounter the same thing and can somebody help? Thank you so much!

    Till More information would be helpful if you can provide it. Which carrier? Did the same SIM work before GrapheneOS was installed? What are the symptoms when the disconnection happens? Does it happen everywhere, or just in one location?

      de0u Of course! Carrier is WeTell which operates within Vodafone network in Germany. Same Sim card works on my OP8 with Lineageos. Symptoms are: "Service not available" message is shown for maybe 10 seconds, then it connects to the network, when i am without Wifi even internet works, then after a couple of seconds it gets disconnected again everything begins again. It is independent of location and i have signal with other phones in the same location.

        That is great information. I am not a carrier expert, certainly not a European carrier expert, so hopefully somebody else will chime in.

        One more question: how old is the SIM card?

        • Till replied to this.

          The Pixel you use with, is simlock/ carrier free? If you don't know, ask some one their simcard and try if that works to connect any service, call or what you now can't.

          I'm no expert on anything, but I can tell you that my GrapheneOS installation on my Google Pixel 7 has no issue working with Vodafone. I got the phone with the mobile contract I have with them and haven't had any connection issues whatsoever.

          After again inserting the Sim-card, i was not able to put in the Sim-Card-pin. After putting in my code, it said: "Error when unlocking your sim Card" or similar. I have now tried putting in another Sim-Card from another carrier. Same error. I tried all things i could find from here: treequell but nothing worked. I am now reinstalling the OS..

          I installed Stock OS and had the same problem. So i guess it has nothing to do with GOS. Ill send back the device. thank you all for your help!
