> Regarding your specific problem, I'm assuming you've set 'Data
Roaming' to enabled per bug #1449990?

Yes, and if the screen is unlocked there is no problem when changing
network.


 > Do you mean that you screen is on, but locked and you see the data indicator disconnect? Or did the screen go off, and when you wake the phone the network indicator shows disconnected before you've unlocked it?

I try to reformulate the problem with a practical example :)

I cycle every morning from home to work through the city.
I start with my phone connected to o2-de (or o2-de+), I lock it and place it in my pocket.
I cycle to work.
When I'm there and I unlock the phone, if it is connected to the same network (o2-de, or respectively o2-de+) there is no problem.
If it is connected to the other one (o2-de+, or respectively o2-de) then there is this problem, so the icon is the empty one and there is no network.

> Have you tried toggling flight-mode and/or mobile data to see if
either also triggers a re-connect?

Yes, I always try to do it first, but in this case it does not help.

> Finally, if you're using more than one SIM, can you please ensure that
the SIM selected for mobile data is correct in Cellular Settings? We had
an earlier bug on the BQ phone where this setting could change from one
SIM to the other. This was fixed in one of the early updates, however
it's still worth double-checking.

I have more than one SIM and I did not check it actually, but after the
reboot it works without problems on the right SIM (the other one is
foreigner and the Roaming is not activated there), I will look at it
tomorrow morning, if it connects to the wrong network.

> Are you familiar with adb and/or shh, could you reproduce the
described scenario again and attach the file /var/log/syslog from the
phone?

I am not familiar with it unfortunately, but if you link me a guide I
will gladly learn ;)

Title:
  Telephon loses data connection when changing tower

Status in ofono package in Ubuntu:
  Incomplete

Bug description:
  bq device, r21

  After experiencing this bug
  https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1449990 I also
  noticed that when the phone silently switches from O2-DE to o2-de+ or
  vice versa, the mobile data connection disappears, the symbol that
  appear is just the empty "angular" signal, if the screen is locked,
  and nothing works.

  If the screen is unlocked then there is no problem, it goes with the
  other carrier and everything is fine.

  The only way to have it back is to reboot, similarly to what happens here https://bugs.launchpad.net/canonical-devices-system-image/+bug/1435328 .
  Also switching manually back to the other carrier does not make it come back.
