967944 - [Flame] SIM Card apparently detected only in left slot (not right slot)

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Vendcom, defect)

Description

[John Hammink]

Flame
build from February 1 (that came with the device)

The SIM card is apparently detected only in left slot, but not the right one.   I alternated T-Mobile and AT&T SIM cards with two different devices, and the issue appears on both.

Settings does not contain the SIM Manager when 2 SIMs are placed in the phone.  I think it has to detect 2 Sims for the UI to show.  Can you confirm enpei?

qablocker as this blocks the DSDS feature

1.3 OEM does work with dsds with the change :
adb shell setprop persist.radio.multisim.config dsds

1.4 DSDS does not work.

Moving to RIL as if this is confirmed to work on 1.3, then it's likely a regression on our side in RIL.

Hi John,

Is Flame our reference phone? Which code did you flash on it, is the code for dual SIM?

I checked with Gaia dev that SIM manager will show if mozMobileConnection length is 2.(https://github.com/mozilla-b2g/gaia/blob/master/apps/settings/js/settings.js#L275) So I wonder if the build you use support dual SIM or not. If build is for dual SIM, then even if there is only one SIM inserted SIM Manager would still show.

Flame = reference phone. The phone is dual SIM supported.

This might be the problem, so rechecking on latest flame image.

Restesting on Foxfone build 7, a.k.a. build identifier 20140218183708  (not able to get remote debugging to work, so no other version information available).

Here are the results I'm seeing with this version (base + foxfone build7):

Gaia      9ea16d757a290de5b374d809e43dc1e99f4f802d

two sims:
SIM Manager shows up (in Cellular & Data settings) for both SIMS
However, it's only possible to toggle on/off data connection for SIM 1 (not SIM 2).  SIM2 Data connection UI is greyed out.

Note that messaging, data and a-gps settings are populated for both SIM cards.  It is also possible to enable roaming for both SIM cards.

Let me know if more information is needed.  It's not easy getting a logcat because the phone is so frequently going blank and dying.

OK ^ that was cellular & data settings, not SIM manager.  My bad.

Another very strange observation with SIM Manager on this build:

When I had active, working T-Mobile SIM in slot one and active, working AT&T SIM in slot two:

SIM 1
T-Mobile
16509965746

SIM 2
No operator
16508610891

but when I switched them, I got:

SIM 1
No operator
16508610891

SIM 2
No operator
16509965746

Clearing qablocker flag - this flag can only be used for issues on existing test workflows, not new test workflows.

Seeing the same results on both the

and

What's more, I'm not seeing even SIM manager or Dual SIM support any more in Settings => Cellular & Data.  Filing a new bug on that.

The dual SIM function as well as setting should be enabled by ADB command on current version(v107 which release on Feb. 20), but still have some issue on it. This function will default open in future release.
Current ADB command to open it are:
adb root
adb remount
adb shell setprop persist.radio.multisim.config dsds 
adb reboot

[Al Tsai [:atsai]]

tested w/ v107 and followed steps in Comment 12. It'll keep searching for signal. Wait for partner's patches.

[Francis Lee [:frlee]]

hi Yanan,

do you have any update?

Comment 15

[John Hammink]

Hi all, just looking into this now.  After flashing 109 (with 107 user image and separate modem files), enabling dsds and restarting the phone, I'm seeing what Al described in comment 13.   

Except on one phone, where it's detected the SIM only in slot #1.

Comment 16

[Tony Zhao]

Hi all,

We did aware of this issue and still working on it, for detail please refer to comments 4 of issue 987410, thanks

Comment 17

[Mike Lien[:mlien]]

verify with v10B build, DSDS is default enabled and both SIMs can be detected normally
