sim-card

There is a "SIM card lock" option in android "setting/Location & security settings" page. It's necessary to input a PIN code after booting if the option is set. Is there any programmatic method to detect if PIN is required ? (not current sim state but the setting option value ex: true/false) You can use the following class: TelephonyManager http://developer.android.com/reference/android/telephony/TelephonyManager.html You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE) TelephonyManager manager

I would like to access the SIM menus on an Android phone using STK. I am trying to write an APK that shows the SIM Menus and perform operations on it. However, since the software would be used by users, replacing the OS core modules may not be an option. How can I do this? This is, unfortunately, not possible.

The SimToolkit application (which is signed by the manufacturer or mobile operator so that it has special

I'm trying to write a program that change default SIM card on my dual-sim android, what functions do I need for this? The Android SDK has no support for manipulating multiple SIM cards. You will need to contact the manufacturer of your device and ask them if they have an SDK add-on or something that enables you to work with multiple SIM cards. If your phone is based on Mediatek, there is a way to do what you want to. Have no doubt about that. Dual SIM Switch Widget (I've developed it) is able to control SIM states on most dual SIM devices with Mediatek's boards. Take a look at this page: http:

We have a product where the user registers by providing their phone number. However after they register they could potentially change their sim. Is it possible to programatically determine if the sim has been removed or inserted? (Thanks if you provide it, but any digression comments on the use of using the phone number in the first place would be irrelevant to this discussion, I don't want to discuss that aspect of things, only the sim aspect). Oleg Trakhman Yes, of course it is possible. Link CoreTelephony.framework to make following code compile: CTTelephonyNetworkInfo* info = [
