Title:
  Cannot send MMS messages with combined contexts with WiFi connected

Status in network-manager package in Ubuntu:
  Confirmed
Status in ubuntu-download-manager package in Ubuntu:
  New

Bug description:
  Cannot send MMS messages with combined contexts in case the WiFi is
  connected, for some operators. Combined contexts are able to handle
  internet data and MMS data. For the operator for which I've seen the
  bug, the data is:

  $ /usr/share/ofono/scripts/list-contexts
  [ /ril_0 ]
      [ /ril_0/context1 ]
          Password =
          MessageCenter = http://www.pepephone.com
          Name = MMS Pepephone
          Username =
          Protocol = ip
          Preferred = 0
          IPv6.Settings = { }
          Settings = { }
          MessageProxy = 10.138.255.43:8080
          Type = internet
          AccessPointName = gprs.pepephone.com
          Active = 0

  Sending an MMS with cellular data and WiFi enabled fails for this
  operator when using a combined context. Disabling WiFi I was able to
  send the MMS.

  The error I see in ~/.cache/upstart/dbus.log is:

  E0513 09:55:03.254148  4565 file_upload.cpp:345] Upload ID{
  d0e5da6eb7664d908ab49b810ff55e01 }  http://www.pepephone.com
  ERROR::Network error UnknownNetworkError: an unknown network-related
  error was detected

  The interface that were up when the failure happened were:

  $ ifconfig

  See attached the tcpdump of the packets sent when this happened. Some
  quick analysis shows that the uploader is sending through the WiFi
  (192.168.1.40) instead of using 10.60.155.62, so it is clearly a
  routing problem. The MMS proxy has private address 10.138.255.43 so it
  is not reachable from WiFi.
