Hello everyone,

I've been using my Jolla phone happily for almost 4 years now, but a few days ago, a really strange error popped up that I have yet to find a fix for. When I open the "Phone" app and try to call someone, it will consistently give me the "No network coverage" error despite a network connection being clearly available. Not only can I send and receive SMS just fine, I can even receive calls, but not make them. I've tried to look in the forums here for a fix but it doesn't even seem like someone's had this problem before... Any ideas on what the cause might be?

Thanks in advance!

Edit: Calling from the terminal gives me the same error and "(true,)" as an output

How do you call someone from terminal?

This seems like some old bugs who where fixed in the past.

See this threads: https://together.jolla.com/question/40725/call-ended-but-phone-is-still-processing-the-ending/

The guy you need from Jolla is Joona. he fixed it in the past: https://together.jolla.com/users/1139/joona-petrell/

I'm afraid none of those threads describe the same problem I have. This situation of supposedly having "no network coverage" has been continuous for at least the last 3 days, and I haven't been able to call anyone at all during this time. I have no problems receiving calls or with the phone not noticing that a call has ended. I also have the latest version of the OS where the bug you mentioned has long been fixed.

I've updated my Jolla1 to v2.2.1.18 two days ago, and started experiencing this issue this morning. The flashing "connected-connecting" data connection status occurred as well, but rebooting the phone fixed that. I however can't place any phone call, even after a reboot, but receiving phone calls, sending and receiving text messages, and 4G data all work. This rendered the phone almost unusable, as placing phone calls is one of my central use cases for this phone.

Same problem here, on an Xperia X with Sailfish X 2.2.1.18.

An actual fix would require Jolla's devs to fix bugs in ofono (something that we community can't do easily). So think about filing a bug on the official Jolla bugzilla. They might ask you for logs, etc.

Meanwhile :

Workaround :

Standard I have a bug procedure :

  • restart alien-dalvik (sometime it's not even a bug, there's just an app hogging some ressource)
  • put phone in airplane mode, wait a few seconds, put it back online (this force to restart the cell modem connections)
  • put phone in airplane mode, restart network connections (either using Sailfish Utilities app from Jolla store or systemctl restart connman.service ofono.service on the console), put phone back online
  • shut down the phone, remove the SIM tray, wait a few seconds, put back SIM inside, turn on the phone (while no cable is connected).

Usually most of the No network coverage problems go away, with solution 1 or 2. Today is one of the few times I needed to go all the way to rebooting.

I have the same phone, same OS version and same problem once a week. What I have discovered that if I go to SETTINGS and NETWORK (mine is in finnish so I hope I got it right) the line under my network operator is flashing connected-connecting continously. This happens when ending a voice call somehow the connection to the network is lost and the phone warns that there are network problems ("ongelmia verkossa" is shown on my screen). By now I will check the settings and if the line under my network provider is flashing I usually reboot. This have always fixed the issue for me.

In my case, the network setting didn't show anything unusual, and actually internet connection usually works. Often, only voice is blocked. (weird)

I have also witnessed every now and then this "continous connected-connecting flashing" and the loss of network. Usually nothing helps but rebooting the damn thing !? :-)

Thanks for the response! I ended up getting impatient earlier today and just reset my Jolla to factory settings about an hour before you posted your workaround. Everything works now, so I sadly can't check whether your procedure would've been successful in my case, but as a factory reset worked, it seems like your solution might as well.

Have to do network subsysten re-start almost daily. Starts to be a bit annoying to be on 4G area without network. Plus there is no way to know when you have dropped of coverage if not actively check something over network. Sometimes has to do phone restart to get back online. Sure it's a bug and has been around since Jolla1.
