I see a lot of original N-Gages on ebay...but will they work without a SIM card? I don't have to have to get cellphone service just to get the system to work...I'd only be using it for gaming.
Original N-Gages and SIM cards
No, you need a SIM card to boot up the N-Gage I'm afraid.
is there such a thing as a dummy sim??
Yes, I suppose there is. According to Ewan's review of the QD (http://www.allaboutngage.com/reviews/review2.php?id=103), that one should come bundled with a dummy SIM.
Any sim will do, even an ancient pay-go ..long disconnected, it just warns you that the sim has failed registration the you can carry on.
