      On my Fairphone 4 with Ubuntu Touch 20.04 OTA-7 and a german amiva (Vodafone) SIM mobile data doesn't work.
      It's a used phone and I think I tested the mobile data with Android.
      At one time with this Ubuntu installation mobile data worked. But after a power cycle mobile data is gone again.
      I tried another SIM card from congstar (Telekom) and mobile data doesn't work either.
      Both SIM cards work on other phones with Android.
      Airplane mode on and off, Data roaming on and off doesn't have any effect.

      I tried serveral ofono commandos and I think here is the problem:

      activate-context

      gives this Error message:

      Error activating /ril_0/context1: org.ofono.Error.NotAttached: GPRS is not attached

      I attached the output of

      list_modems

      Could anyone help?
      list_modems.txt

          @Martin5 What happens when mobile data don't work? I'm actually having an issue on mine too and turning on mobile data will just change the Wifi icon to something like it's trying to connect but never connects. However, there are times mobile data works fine. In my case, there are multiple possible causes. This is a new FP4 I transferred to from my old FP4. I also upgraded to OTA-8 before transferring. And lastly, my new FP4 has an eSim configured on Android but it's inactive in UT.

            @kugiigi I'm not sure if I understand your question correctly. When mobile data doesn't work, the only effect is that the button for mobile data moves to green. Beyond that I cannot see anything happen.

              humm, did you ever had battery-saver ?
              If so maybe the service is still running if app data hasn't been cleaned ?
              systemctl --user status batterysaver.service

                @lduboeuf No, never used that.

                This is by the way what happens when I encounter this issue. The Wifi icon has dots and stays like that.

                  @kugiigi I'm sorry for providing the wrong answer yesterday. It's the same like in your picture: Activating cellular data brings the dots in the Wifi icon.
                  @lduboeuf Never used that too and output of

                  systemctl --user status batterysaver.service

                  is

                  Unit batterysaver.service could not be found.
