I have a simple JavaCard applet installed on my SIM card. I try to communicate with my applet using Omnikey 5121 CL reader and NFC-enabled Sony Xperia L through NFC/SWP (single wire protocol).
The problem is I cannot select the applet - as a status word I get 6999. The LED light is turned on, so I suppose there is some communication between reader and the SIM card. Moreover, I cannot select my security domain either.
However, when I put the SIM card into a standard contact smartcard reader, everything works fine.
Is there any extra configuration of Android OS, SIM card, NFC modem etc. I have to setup before communicating with SIM card over NFC? Any ideas?

Receiving status code 6999 in response to the SELECT (by AID) command is a clear indication that the applet was not found/not selectable. If the applet has been installed and is selectable (using the same AID) over the contact interface of the UICC/SIM card, then it is likely not made selectable over the SWP (contactless) interface. Typically secure elements allow to selectively enable/disable applets for specific interfaces (in addition to this, applets can detect over which interface they are selected and can react accordingly).
Applets typically need to be explicitly made selectable over the contactless interface by setting the Contactless Protocol Parameters in the INSTALL (for MAKE SELECTABLE) command (or later on by doing a registry update). See Amendment C to the Global Platform Card specification for further details.
Btw. the security domain not being selectable over the contactless interface is not unusual for a SIM card. Card management is typically restricted to the contact interface for security reasons. (Card management over the contactless interface is typically not used in production environments anyways.)
