Xperia C4 Dual E5333 - deactivate SIM function not working - Android 6 bug?

[Arnoldinho]

I have an upgraded Xperia C4 Dual E5333 (Andoid 6.0) with 2 SIM cards (upgrade done with Xperia Companion)
SIM1: GSM only  - used for PHONE
SIM2: LTE/ (preferred)/WCDMA/GSM   - used for internet


To decrease the battery usage, I want to Disable the SIM2 card when I don't need the Internet access.
used the "Settings -> SIM Cards", and wanted to disable the SIM2, but I got: "Error, can't disable all the SIMs." - I don't know why this option is not working as my SIM1 is absolutely active.


I read the related book here, but no solution.

I disabled Mobile Data, and tried many many combination in "Settings -> Data Usage - Mobile Networks", but the "disable SIM" function is still not working AT ALL --- AT ALL, as I have tested it wth SIM1, and also got the same "false" error.
There is ONE BUTTON solution to acivate/deactivate SIM2 to decrease the battery usage of it - I want to avoid any mobile signal when the SIM2 is disabled, this should be done by the menu in "Settings -> SIM Cards", but not working, and I think, this is a bug.

hi, could you try the following?

1.) switch the sim cards place.

2.) try the settings while on safe mode

Hello @Arnoldinho,

As @nolramlb suggested, is there any change if you switch places for your two SIM-cards? Are you then able to disable any of the SIM-cards under the Dual-SIM settings?

However if you simply wish to disable Mobile data in your phone you can do this under Settings > Data usage. Tap the slider Mobile data to disable it.

Hello, tryied the SIM card change both in Normal and in Safe Mode - I got the same "false" message 😞

I think, this is a bug this Android release, bu if you have any idea t otest this function, please share it with me.

I know, how to disable the Mobile internet, but I want to fully switch of the SIM2 as it should work.

Thanks, Arnold

It's not impossible this could be related to your service provider. I would recommend checking in with them if this is allowed or not, I've tested in one of the devices we have here and as able to disable one of the SIM-cards.

If you should be able to disable any of your SIM-cards according to your service provider I'd suggest you perform a software repair using Xperia Companion. Since this will reset your phone, make sure to create a backup first.

Hello, I'm having a same issue as Arnoldinho, I cannot deactivate SIM on my C5 Ultra Dual after an update to Android 6.0.

Previously, before an update when I was using Android 5.1 it was working fine, and now an error message appears "Error, can't disable all the SIMs".

I've tried it in safe mode with no success, and trying different service providers haven't made any change either.

Deactivating the SIM(s) is very important phone feature to me and now the button gives me an error message.

(@)Hi Arnoldinho, please advise if you had luck using Xperia Companion, and does deactivating SIM finally works?

(@)Sony support, please advise would there be a fix for this issue in case Xperia Companion cannot help? If not, please advise how can I rollback to Android 5.1 again?

Thanks a lot in advance & I look forward to your reply.

Brads,

Miro

Hello Mir0. I will give a try by Xperia Companion to repair my software when I will have eough time to setup my phone again - will inform you about the result. Regards, Arnold

Hi @Mir0,

I'm sorry to hear that.

Is there any change if you swap places with your SIM-cards?

Do you know if your phone might be branded to a specific service provider? If that is the case it's not impossible that this is the cause of this not working.

Should the above not help I would suggest performing a software repair.

I cannot assist you with installing any previous or unsupported software, if that is what you wish to do I can only refer you to our developer website: http://developer.sonymobile.com/.

@Arnoldinho, if you performed the repair, please let us know how it went!

[Mir0]

Hi @Arnold, thanks for reply, I'll keep fingers crossed for Xperia Companion to repair SIM(s) deactivating function.

Hi @Didrik, thanks for response, I'll visit the developers site too. Please be informed phone is not branded to any specific service provider and swapping SIM-cards, unfortunately didn't work. I've tried using only one SIM, just to test it, but with no success. Using the phone for the past year, before an update to android 6, and now after that update, it seems that the main issue lies in that very same update to android 6. Please advise how can we escalate this issue to further support level that might eventually result in sort of software patch for this SIM(s) deactivating function for end users of both C4 Dual and C5 Ultra Dual?

TEAM,

I have upgraded Xperia C4 Dual to Andoid 6.0(upgrade done with Xperia Companion) and made the biggest mistake of my life .

Infact I already made the biggest mistake of my life by purchasing a phone of the most disrespectful and most customer decentric company THTS SONY.

To decrease the battery usage, I want to Disable the SIM2 card when I don't need the Internet access.
used the "Settings -> SIM Cards", and wanted to disable the SIM2, but I got: "Error, can't disable all the SIMs."

This matter was already reported to SONY people in the month of October (http://talk.sonymobile.com/t5/Xperia-C4/Xperia-C4-Dual-E5333-deactivate-SIM-function-not-working-And...) I dont why it was not been rectified so far and I was also not been informed by any of the agent while I  had a talk with them regarding the upgrade, before actually doing it else I would not have dne it.

When I contacted them with this issue I got the most disgusting reply " format ur fone" how ridiculous is this, formatting my phone means loss of all data along with loss of all applications which are based on my phone number as I dnt have that number active anymore from last year , but i have been using it for last five year, how could sony make me accountable for their carelessness  that they did not upgrade their knowledge system even after being informed about this problem.

SONY I AM VERY DISAPPOINTED WITH YOU. YOU LOST A LOYAL CUSTOMER TODAY.
