hi Paco,

Thanks for reporting this! However this bug is old and specifically related to the Galaxy Nexus (Maguro) phone. Although your report sounds similar, I believe it needs either a new bug or should be added to a currentlu active bug thread (also depending what device you are using). There are a few issues with mobile data on both aquaris and nexus at the moment. Your issue might be related to them (so maybe not related to roaming at all).
Best thing to do is call out on IRC #ubuntu-touch to the developers of this part of ubuntu touch and decide with them if it needs a new bu or adding a +1 to an existing one.

I have not seen this issue on Mako so this bug thread ought to be closed
i think.

cheers,

Mat

Title:
  Cellular dataroaming fails on Ubuntu phone(Maguro)

Status in ofono package in Ubuntu:
  Incomplete

Bug description:
  short description: I was in Switserland recently using Maguro with a sim from my dutch provider. I was expecting to be able to establish a data connection through a local swiss provider when I enabled(toggled) both Cellular data and Data roaming. However, this did not work. No internet connection was created.
  (To make sure, I checked that on an Android phone, using the same sim, this did work)

  As I am lazy :) and this has been discussed on the Ubuntu-phone
  mailing list, I will copy the final part of that thread below for full
  details:

       I live in holland and have a dutch carrier sim. I was in Switserland
      last week of januari (fully updated the phone before I left so I would
      have been on something like r150, if thats important).

  
  Yes, in general build numbers are helpful whenever discussing such issues.

      /Can you clarify what you mean by "But when selected, no data
  connection

      is created"?  Did you mean that when both "cellular data" and "data
      roaming" are selected,/

  
      Yes, thats what I did exactly. The local carrier that always appeared
      automatically behind the 'carrier' label on the Cellular tab of system
      settings was 'Swisscom'.And If i remember correctly, the name of my
      Dutch provider appeared behind it in parantheses.
      (I am back home now so I am not able to replicate this behavior atm)

  
  OK

      /or are you referring to selecting a carrier/

  
      No. That did not work. Refreshing the list of available carriers manualy
      resulted in a continiously spinning wheel and not much else, if I am not
      mistaken.

  
  Also good to know.  We've been looking at the various devices and maguro seems to be a bit broken with regards to operator scanning.

      /One question, do you know whether or not your SIM card is from a

      primary operator ( eg. Orange, T-Mobile US, Telefonica, ... ) or a MVNO
      ( eg. Straightalk in the US )?/

  
      I am not quite sure: My dutch carrier is Telfort. It is a subbrand of
      KPN Mobile, which is a primary operator. Seeing as Telfort is just a
      brand owned by KPN, you might expect it to also be recognized as a
      primary operator, but that probably depends on how they implemented the
      Telfort network within KPN. I don't know enough about that.

  
  I guess in hindsight, it's not that critical when roaming.  One last question, if you run the script:

  /usr/share/ofono/scripts/list-modems

  Can you check the MobileCountryCode and MobileNetworkCode listed under
  the NetworkRegistration interface?  Do the value s

  MCC = 204
  MNC = 12

  
      /Lastly, ofono logs messages to the standard syslog ( /var/log/syslog ).

      The command "grep ofonod /var/log/syslog" is a quick way to extract
      these messages, which can be very useful when diagnosing telephony
      problems./

  
      Grep ofonod gets a lot of info. I am afraid I am not a good enough judge
      on which bits are relevant so I will gladly leave that up to you and
      others :) . I have extracted the entire syslog for the relevant period
      and posted it for you guys to have a go at it if you feel like. Here is
      the link:

  http://paste.ubuntu.com/6957213/

  The log will show that I tried to set up a cellular data connection
  many times. As said, this failed every time.

  Hopefully someone can confirm (or deny) this.

  Cheers,

  Mat
