Hi,

I have my Jolla Phone since for about 10 month. One thing that is really s*g is that 4G almost never works correctly (3G is better). Now I have investigated a little more in this and I have found some log-message which may detail the problem:

Jan 29 15:55:08 Jolla kernel: PM: resume of devices complete after 4.635 msecs
Jan 29 15:55:08 Jolla kernel: msm_suspend_end, is_wakeup_from_pc = 1
Jan 29 15:55:08 Jolla kernel: QSEECOM: qseecom_receive_req: Interrupted: exiting wait_rcv_req loop
Jan 29 15:55:08 Jolla kernel: QSEECOM: qseecom_ioctl: failed qseecom_receive_req: -512

These messages appear very frequently and in my opinion this indicates either a bug in a driver or a hardware failure. Maybe someone is able to tell me more about this problem? Is my Jolla broken?

Ok, I am trying to detail this. 4G connection is never working if I switch off my WLAN. This is sure (points to connman?). If I take my Handy to work (no WLAN, a certain period time in between) it is possible that it works. But there are also situations in which 4D (and sometimes 3G) doesn't work although I didn't turn off WLAN or did anything else. I simply try to open the browser and get the error. Switching internet connection on and off in the settings dialog always shows me the connection error message.

After googling MNVO, I must say yes, I am using an MNVO: Constar (it uses Telecom). But 3 month ago I used Vodafone directory (no MNVO) and had the same problems. At the 6th of february I will switch to the MNVO McSIM (which uses Vodafone).

I am running the current Sailfish OS release 1.1.1.27.

Update

I found out that the systemd-service with the name ofono is responsible for the connections. Facing the problems again today, I have extracted a log-file of this daemon. I think the following part is interesting:
