NFC java card contact reader OK, but contactless can't select the applet..

hope to solve the problem here..

I read many entries, some of them helped me really.. But I still have some problems..

I develop a Java Card applet and install it in a sim card..

I have a contact reader ACR1281U, and contactless NFC reader ACR122U.

With a contact card reader (ACR1281U) I can select the applet with the ISO-7816 APDU commands and communicate without any problem. Everything works fine..

The problem:

I have an Otiglobal COPNI™ (Contactless Payment and NFC Add-On):

I use this Add-On, to communicate with the simcard via contactless reader..

Unfortunately, if I send the same APDU commands, I always become the response 6A82, which means no file found..
It seems I can communicate with the sim via ISO-14443, but not ISO-7816..

Do I have to initialize something in the applett or the reader to work ISO-7816 and select the applet via NFC reader? or something else? like to activate the reader or the applet for NFC..

Or am I on the wrong way?

Thanks in advance..
