833116 - Unable to get data connection due to phone thinking it is roaming

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: General, defect)

Description

[:gerard-majax]

When your provider is using another provider's network, like Free Mobile in France, for roaming where it has no coverage, it is impossible to get data connection unless enabling data roaming in settings. The checkRoamingBetweenOperators() is successfully executed, since the roaming indicator is not present anymore.

This is happening on Nexus S, Otoro and Unagi.

[Fabien Cazenave [:kaze]]

Same carrier, I confirm I've always had to enable roaming for my Otoro and Unagi devices.  That’s OK for me but real-world users would probably never think of enabling roaming for that (or wouldn't enable it because of the message that says it will cause additional charges).

Comment 2

[:gerard-majax]

As far as I remember, it's notified by the provider that you might have to enable roaming. Maybe a nicer solution would be, like I see on CyanogenMod (and mybe stock AOSP), to have a « National Data Roaming » option, that could be automatically set by checkRoamingBetweenOperators() when we have a different network identifier but same country.

This, of course, if the data roaming can't be enforced from the RIL JS code.

Be aware that in some situation, this is not "free" roaming either.

Example in Canada. WIND has roaming agreement with a national carrier (shows a "WIND Away" on the phone in lieu of carrier name). The data cost *a lot* when roaming on that carrier. So we should make sure that whatever solution is implemented that we don't assume the roaming data connection is free.

I am worrying about if this would block shira(v1.0.1)?

dcoloma:
Is there any people can help to investigate more on target market?

[Daniel Coloma:dcoloma]

Brazil has a very particular roaming situation, as it has roaming across States. It sounds like this deserve attention. David, can we test this in Brazil and also with a MVO in Movistar Spain?

If this does impact TEF, this bug would be tef+. Waiting on feedback though.

Comment 7

[Beatriz Rodríguez [:brg]]

We saw a similar issue in October during on site testing in Brazil and it was fixed by then. I am not 100% sure if the issue is the same I just include here the bug reference number in case it helps:

Hi, 

Retested with MVO in Spain (different MNC), and works fine (data connection is ok, and no "roaming situation" is detected). 

We're checking how to test this in Vivo, we'll let you know asap. 

Rgds!

Please re-nom if/when this is reproduced and deemed critical.

Waiting to hear back from dpv before removing QA Wanted.

[David Palomino [:dpalomino]]

Hi Naoki, 

We're arranging some tests in Brazil, but this will take some time because of logistics difficulties. For us, as Daniel and Beatriz have already commented, it could be an issue for Brazil. 

As commented by Beatriz, the issue found in Brazil time ago: 
https://bugzilla.mozilla.org/show_bug.cgi?id=797972

It was already fixed, but we have to check if there's a regression. 

BTW, as commented in comment#8, it was retested with a MVO SIM card in Spain (Tuenti, in Spain, with different MNC), and behavior was ok. 

We let you know as soon as we'd have any testing update in Brazil. 

Thanks!
David

David - Do you have any updates on testing update you mention in comment 11 for Vivo?

Comment 13

[David Palomino [:dpalomino]]

Hi, 

Testing with Vivo was delayed indeed. We hope to finally execute, but it's not something we can do at short term. 

thanks, 
David

[Beatriz Rodríguez [:brg]]

David, any update here? :-)

Comment 15

[David Palomino [:dpalomino]]

Hi, 

We're trying to get a SIM card out of SP (with different MNC).  I think tomorrow we'll be able to have some results here... 

thks!
David

[David Palomino [:dpalomino]]

Hi again, 


Retested today with different MNC SIM Card (tested in SP, with SIM card from Campinhas), and worked fine. No roaming indication shown, and data was available.
