Detect "Ask Every Time" setting on outgoing calls for Dual Sim Phones

I am working on an app that successfully intercepts NEW_OUTGOING_CALL broadcast on outgoing calls and handles calls accordingly. Everything works perfectly fine on single SIM devices.
On Dual SIM devices, I am able to detect which SIM is the default calling SIM by reading the ICCID (it changes depending on which SIM is the default calling SIM) and I am also able to handle calls accordingly (either handle it by my app or pass it back to the native dialer).
The problem I am facing is when users choose the "Ask every time" option. When they choose that option, the ICCID is still read as whichever SIM was set as the default SIM last.
I would like to detect that users have chosen this option so I can pop up a dialog thats asks them, which SIM they want to conduct their call over.
I searched through stackoverflow and scoured everything I could find on Dual SIM but I couldn't find an answer to this question. All the logic I added into handling calls on Dual SIM phones has been rendered useless by this part.
Is there something I can read (whether its a broadcast or an intent extra or an android setting) that would tell me that users want to be asked which SIM to use every time they attempt a call?
Thanks for the help.

Dual sim api (like Dual Sim Control)

I need to develop an application to enable data of a dual-sim android phone.
For example, sometimes I need to enable data on the first sim, and other times for the second sim.
I discovered an api called mediatek
It is an api that allows us to manipulate dual sim. I take a look on the playstore, and then I found the application
Dual Sim Control which allow us to manipulate sim card of the phone.
When I look at the api reference of mediatek, I only see some method to get the sim card information but no method to change the sim information.
I need your help to enable or disable data on the dual sim android phone baseed on mediatek processor.
Thanks

How to find out phone number of a sim given its IMEI number?

I have a dual sim Android phone. Using this solution I retrieve IMEI numbers of both sims.
Given the IMEI number, how can I find out the phone number of each sim?
There are methods getDeviceIdGemini(int slotId) and getSimStateGemini(int slotId) it is possible to find out the IMEI number and the state of each sims.
I'm looking for a similar method for reading the phone number of the sim.

You can't. Phone number it's not stored on sim card, it's stored on operator's servers. Look for TelephonyManager.getSubscriberId(), this will give the unique id for each SIM.

Programmatically obtain the phone number of the Android phone
Basic answer- there is no way to get your current phone number. There's things that sometimes work, but not always and not on all carriers.

No,
Android doesn't support dual sim devices.
See: Detect the status of two SIM cards in a dual-SIM Android phone
as Android does not support multiple SIMs, at least from the SDK.
You can contact your device manufacturer and see if they have an SDK add-on or something that allows you to access the second SIM.May be an API which can help youto get your desired result.
Although you can find out the status of the device whether it is Dual sim or not by using this link Android : Check whether the phone is dual SIM

Using reflection, I looked at the methods of TelephonyManager and found this method: int getLine1NumberGemini(int).
I tried to invoke it (getLine1NumberGemini(0) for first sim and getLine1NumberGemini(1) for the second). In both cases I received an empty string.
But the reason for this seems to be the inability of the phone to get the phone number of my sims:
TelephonyManager.getLine1Number() returns empty string as well.
When I open "Sim management" in the settings of the phone, no phone numbers are displayed.

How to capture event of removal of SIM card in android?

In android, how do I capture the event of SIM card removal? Usually on phones like htc 1x, we can remove the SIM card without removing the battery and there is no notification as such of power off or restart of the phone. I want to capture the event of SIM card removal, so that I can pop-up some messages.

Check answer number one, You can check whether the sim card is available or not in device by using TelephonyManager class.
How can I check whether the Sim Card is available in an android device?

According to this answer, the system sends out an android.intent.action.SIM_STATE_CHANGED intent when the SIM card when the SIM card changes, for example when entering or leaving airplane mode, and presumably also when removing or inserting a SIM card.
It should be noted that as this is an undocumented API that may change without notice, and it may also not be available on some devices.
As for shutting down or restarting, according to this answer, the system sends out an android.intent.action.ACTION_SHUTDOWN intent (on Android 1.6 or later).
