      I've been using Focal for three weeks. Today, after a reboot, the cellular connection is not established anymore. Instead of displaying my provider name, now it displays 'unknown'. If I remove my sim card, it says 'no sim'
      The reason for the reboot was the unability to start Morph, tapping the icon did not result in starting the app. After reboot, Morph works again, but the cellular connection is gone. Rebooting doesn't solve the issue. The SIM card is good, as it still works OK in my Nexus 4.
      I noticed some different messages in the ofono logs. What should i do to fix this issue?

      Ofono log when SIM unknown is displayed:

          @WillemHexspoor also have you tried shutting down and then booting up, instead of rebooting? I haf a similar issue on my Jingpad today, but with wifi. Rebooting did not help, but shutdown, then startup did restore it to a working condition.

            @lduboeuf I changed to devel just before posting this, but it doesn't fix the issue
            @arubislander I've tried both rebooting and complete shutdown followed by manually initiated booting, it doesn't fix the issue

              I just flashed to stock android and the issue persists. I assume a hardware failure

                If you can access sim tray contact pins directly, try to clean them up with isopropilic alcohool (or normal ethanol 70/90%) on a tissue or alike.

                If you can't access pin directly, try to put some alcohool on sim, just a thin layer, on simcard contacts, and insert it in sim tray, pull of and clean sim with piece of tissue, and repeat this multiple time.

                Device shutted down obviously.

                An before power on back, wait for any alcohool to vanish, use a hair dryer if needed.

                  @WillemHexspoor maybe the sim-card itself is broken? I've had an issue like this with a specific batch of a simcard in the past.

                    @Luksus I would think unlikely if it works in another phone.

                        I reinstalled Android, the SIM card still did not work properly. I was able to read the correct provider name in the phone settings. I tried different SIM cards from different operators, all had the same issue. I could read the operator correctly, but no cellular connection did not work.
                        Than GPS also started to show issues, in the first weeks I was able to get and hold a fix. But now the first fix was ok, but after a couple of minutes the GPS stopped working.
                        I opened the device, because previous owner said it got a new battery. half of the screw were missing. I needed my phone for work and had no time for further investigation.
                        In the end I bought a new Pixel 3a and am installing UT at the moment.
