Jolla not receiving and/or sending SMS

There are already some reports regarding different issues of the SMS engine, so have a look at them:

Also have a look at the BTRFS issue and check if you are fine with your metadata space: https://together.jolla.com/question/30822/root-and-home-disks-full-and-causing-various-problems/

As far as I know is the delivery report itself a SMS, sent by your phone, but cost free and invisible. So your phone is reacting.

I would try to open the database located in ~/.local/share/commhistory/commhistory.db manually. Copy this thing (!) to your desktop computer or elsewhere and use a sqlite managing application. (In Ubuntu I use SQLiteman, but there are some similar programs for windows.) The content is in "Main|Tabellen|Events", you will find the whole communication protocol there, including content and metadata. Try to find the lost SMS there, or some irregularities, so you will know that.

Once you have stored this database and know you can access your data, you may delete this file on the phone and reboot. The (empty) database will be recreated immediately. If the old database was damaged, this will solve the problem. - But seems there's no way back, it's not possible to simply overwrite the new file with the old one to have your old SMS reappearing in the phone. You might use the regular backup mechanisms for doing so. (Edit: you can still do it, I just tested it. Had to delete the two other files in this folder, too. After a reboot the old messages reappered. But that's not the official way to handle these things, I guess...)

If then there are still lost messages, I have no idea anymore....

@Alex - these questions are not related to my problem. But they help me to debug/log this sh*t... Thank you :)

@Robomike - Thank you, I loaded the database file using SCP and checked it's contents, but the entries are the same as described above (conversation). So I think, that my Jolla really does not receive the messages, or get's an error while receiving them and is not able to write them into the database. I think the only way to find the cause is to write a script, which sends many SMS one after another and log what is happening on both Jollas :/

since a week i have quite regurarly: 'Problem with sending' messages when i try to send an sms it usualy works when i click on retry, but it is not very comfortable this way ;-)
