Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::Cost Control, defect)

Description

[Marina Rodríguez [:mai]]

+++ This bug was initially created as a clone of Bug #1083541 +++

Description:
If the user has a SIM Pin enabled, and boots the phone with Airplane Mode enabled, the Usage app will display an odd looking loading screen when launched, which the app will not be able to progress past.

Note, if the Usage app is launched just with Airplane mode enabled, it will launch normally.  If it is launched with just SIM PIN enabled, it will display an appropriate error message.
   
Repro Steps:
1) Update a Flame device to BuildID: 20141015001201
2) Perform the initial set up for the Usage app
3) Enable Sim Pin
4) Enable Airplane Mode
5) Restart the device
6) Launch the Usage app
  
Actual:
Usage app displays endless loading screen
  
Expected: 
Usage app displays an error message for the user.

Currently,
When flame boots up with airplane mode enabled, gecko only knows there is a sim card inserted, but don't know more detailed information, e.g. is it a GSM card? is it locked? (because the radio is off)
So in such case, gecko reports card state as 'unknown' given that we don't have enough information about the sim card.

We should add an error message for this scenario (assuming the bug cannot be fixed), the message should be specific and understandable to the user.

Hi,
Is the error screen only happens when restart the device with airplane mode? Or it also happens in other uncertain cases?
If geko knows the device is in airplane mode and it only happens in the case you describe, we can drop the exist string:

"Please turn off airplane mode to enable Usage."

But if this error also happens in other unknown cases no matter in airplane mode or not, we may need new string to cover all possible error cases.

Hi,
I don't know if there are another way to reproduce this scenario. 

Hsinyi, could you help us with this? Do you know if it exists another way to reproduce the scenario where the simcard returns the 'unknown' state?

Saludos

A possible scenario is if my device is GSM mode and I insert CDMA SIM card, or vice versa.

Any update?

[Juwei Huang[:juwei]]

I think Hsin-Yi's case is more like a general issue across the whole device, not specific to usage app. If users insert a CDMA SIM card into a GSM device, it just not work in any cases including data connection.
So I think this error case should be handled by a higher level instead of app specific level.

Yet if it cannot be resolved right now, the string can be:

"Unknown Error ! 
Please make sure your airplane mode is off. "

Need info Matej for adive.

Hi Matej,
In this case we need to provide a string that includes both "Please turn on airplane mode to use usage app" & "Unknown error so we cannot open Usage app"
It would be great if you can provide some advices.
Thank you!

It seems odd to tell a user that the error is "unknown," but then give them a suggestion. It implies that turning off airplane mode will fix it.

Do we have to say "unknown"? If not, it could be:

Error 
Please make sure airplane mode is off.

Ok cool!
Thank you for your advice :)

Hi Marina,
Can you help with this? The message would be
"Error
Please make sure airplane mode is off"
