Think I've got the same problem. Since a while my phone (N4) hardly switches back from 3G to 2G, reception is totally gone than. 
Changed my provider a few months ago to eplus/O2. Probably the same time troubles started. Usually I restart the phone.

Title:
  National Roaming not working

Status in Canonical System Image:
  Confirmed
Status in ofono package in Ubuntu:
  Confirmed
Status in ubuntu-system-settings package in Ubuntu:
  Confirmed

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.
