I own a samsung blackjack and it works just fine without the sim installed. when you turn it on it just says invalid/no sim then you push ok and it works just fine, you just cant make phone calls.
Can anyone tell me if the pocket pc style smartphones will operate without a sim card. In other words, will a phone like the cingular 8125 with windows mobile allow you to use the pda functions if you do not put a sim card in it and sign up with a carrier? I would like to buy one of these phones but I do not need to change carriers right now and would just like to use excel and word.
