the sim card type is your 9-month subscription for xplus and inxtv from hotbird. the funcard 7 is used to load the dragonfiles (latest is predator 349) so that you can view the encrypted channels (or whatever is left of it anyway). for legal purposes, most CAMS are being shipped not pre-programmed. but you can get the files on most forums. you need a card writer (or CAS3 if you have the budget) to reprogram your T-rex.
