i would guess - if the encryption of the channel(s) you d want to subscribe is the same with encryption of the card,
Globecast would inform you that the same card could be used...
But if the encryption of the channel(s) happened to be not the same with encryption of the card, then it's only logical to assume, that another card would be needed.. and that Globecast would provide it to you
Can call directly to Globecast by the way also.. and ask them directly
