Multiple SIM Card Support

Android 5.1 adds support for using more than one cellular carrier SIM card at a time. This feature lets users activate and use additional SIMs on devices that have two or more SIM card slots.

You can access information about the currently active SIM through theSubscriptionManager class, including whether or not the device is considered to be roaming on the current network. This information is useful for developers who want to throttle their apps‘ data access down or off for device users who are sensitive to data access charges. Your app can be alerted to changes in a device‘s current network connection by requesting theREAD_PHONE_STATE permission and settingSubscriptionManager.OnSubscriptionsChangedListener on theSubscriptionManager object.
