This method assumes that only dialable phone numbers are passed in; non-dialable numbers are not considered emergency numbers. A dialable phone number consists only of characters/digits identified by PhoneNumberUtils#isDialable(char).

The subscriptions which the identification would be based on, are all the active subscriptions, no matter which subscription could be used to create TelephonyManager.
