Default [Q] SIM software using custom ROM

Hello,

I have just installed Xperia Ultimate HD ROM 3.0.2 and CTCaer 2.8 on my Xperia Ray (Urushi / ST18i).
I now have trouble using my Mobile-ID software on my SIM card. Is there a way to get this to work on this ROM?

Edit: SIM toolkit is the software I am missing.

It was working fine on the official ROM and on CM10.

Cheers.
