It is difficult to say what might be happening. list-modems shows that
NetworkRegistration mode is automatic, and the modem is registered to
symio's Edge network (2G), although the preference is umts.

The issue here is that we do not have that much control over the modem
FW: if there are 2 available networks, and one of them is seen by the
modem as a roaming network, the modem will probably register to the
other network even if it has to use a worse technology.

Please try going to

SystemSettings -> Cellular -> Operator -> Operator

and then manually select the O2 network and check if you can register in
this way.

Title:
  National Roaming not working

Status in Canonical System Image:
  New
Status in ofono package in Ubuntu:
  New

Bug description:
  I'm using a simyo (German E-Plus mvno) and when E-Plus and o2 joined
  forces, they enabled national roaming for 3G data connections
  (https://www.simyo.de/faq/national-roaming-18262.html).

  This however doesn't seem to work at all for me. My device (bq Aquaris
  E 4.5) is stuck in the simyo (E-Plus) network and has never registered
  to the o2 network so far. This is unlike bug 1449990 which claims that
  national roaming would be working if roaming is enabled in the
  settings. I can not confirm that. I have roaming enabled (and
  international roaming works fine), however, national roaming doesn't
  kick in.

  The problem now is, that ever since those operators enabled national
  roaming, the E-Plus network seems to be degrading and now has reached
  a point where I cannot use a mobile data connection inside buildings
  any more.

  Looking at my app download statistics, 25% of all Ubuntu phone users
  seem to be located in Germany. Given that E-Plus has a huge amount of
  mvno's I estimate this issue is affecting a quite large portion of our
  users.
