-    * Toggle logical modem on and off. The difference with setRadioPower is,

+    * Toggle logical modem on/off. This is similar to @1.0::IRadio.setRadioPower(), however that
+    * does not enforce that radio power is toggled only for the corresponding radio and certain
+    * vendor implementations do it for all radios. This new API should affect only the modem for

+    * enableModem() are set to on for it.
+    *
+    * SIM must be read if available even if modem is off/inactive.
     *
     * @param serial Serial number of request.
     * @param on True to turn on the logical modem, otherwise turn it off.
