[Bug 1281848] Re: Cellular dataroaming fails on Ubuntu phone(Maguro)

 

I marked this one as fixed because it has been a long time since
development on Maguro was active. I have recently traveled to
Switserland again with a Nexus4 UT and used data with no issue while the
simcard is still the same that i used when reporting the bug.

New ofono bugs should really be reported to new or other existing
threads.

** Changed in: ofono (Ubuntu)
       Status: Incomplete => Fix Released

Title:
  Cellular dataroaming fails on Ubuntu phone(Maguro)

Status in ofono package in Ubuntu:
  Fix Released

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
