I purchased a used note 2 from a pawn shop, tried to put a straight talk sim card into it and it has no slot to insert the card, I watched several Utube videos to find out what to do, every video shown has a slot for a sd card AND a sim card, mine doesn't have/look the same, any clues as to what to do???
Assuming that you are in the US, does your phone have a Verizon or Sprint logo ? If so, it is the CDMA version and will not support sim cards.
