Attachment: foo.txt

+++ This bug was initially created as a clone of Bug #961927 +++

If data call is established and enter into no coverage area, the registration status is still 'registered'.
I think it is caused by below error, so that gecko doesn't update status successfully.

After checking the RadioInterfaceLayer.js, I guess the JavaScript Error is happened in below function.

checkRoamingBetweenOperators: function(registration) {
  let iccInfo = this.rilContext.iccInfo;
  if (!iccInfo || !registration.connected) {
    return;
  }

  let spn = iccInfo.spn && iccInfo.spn.toLowerCase();
  let operator = registration.network;
  let longName = operator.longName && operator.longName.toLowerCase();
  let shortName = operator.shortName && operator.shortName.toLowerCase();

  let equalsLongName = longName && (spn == longName);
  let equalsShortName = shortName && (spn == shortName);
  let equalsMcc = iccInfo.mcc == operator.mcc;

  registration.roaming = registration.roaming &&
                         !(equalsMcc && (equalsLongName || equalsShortName));
}

I think I know the possible case to trigger this error.
But unfortunately I did not reproduce yet. :(

1). We should check |network| here as well for the case that operator information is not ready yet.
2). Use |connected| as a condition is not so accurate. The |connected| of data is true only if the "default" connection is established. So for the case that device doesn't have "default" connection, the |roaming| of data will not be updated correctly. So I propose check |state| instead.

------
  if (!iccInfo ||
      !registration.network ||
      registartion.state != "registered"){
    return;
  }

Now I am working on marionette test cases.

Block bug 961927 which is 1.3?, so mark as 1.3? as well.

Attachment: Part 2: Refactor test_mobile_{voice|data}_state.js and add more tests for data roaming status, v1

Detailed information about this patch:
1). Put common code in mobile_header.js.
2). Refactor test_mobile_voice_state.js.
- Include mobile_header.js
- Move the cell information tests for voice to a separated file, test_mobile_voice_location.js. (Just like we have test_mobile_data_location.js for data)
- In original cell information tests, we did not restore cell information to default, it will affect subsequent tests. Correct this missing.
3). Refactor test_mobile_data_state.js.
- Include mobile_header.js
- Add more tests for roaming status of data.

(((Note: I think we should also refactor other tests. Let's do it in another bug. ;))))

This bug blocks bug 961927 which was marked as 1.3+ already.
I think this bug should be 1.3+ as well. Could someone help to triage this?
Thank you.
