title: Detect the status of two SIM cards in a dual-SIM Android phone
body: <p>I want to detect whether two SIM cards are there in my dual-SIM android phone programmatically. I found one API (<code>TelephonyManager.getSIMState()</code>), but it is for normal single-SIM phones. Are there any APIs to detect whether or not two SIMs are inserted in my dual-SIM phone?</p>
