I would like to know if all of your nfc phones (belle) are based on the secure element based in the UICC (NFC SIM) or if you have phones with embedded secure element?

Supposing that I have a partnership with a MNO or a UICC manufacturer and that I have my cardlet installed of the UICC put in one of your NFC phone (belle), is it today possible to access the cardlet via an external reader (maybe APDU commands), in other words is it possible that the phone works in total "card emulation" mode even if the phone is off ??
