Does anyone know what is wrong with it? I simply insert the micro sd into the KRAZR and then it comes to home page and it says "No service" at the top. From there i can not go any where. It just locks up there. Are PNY cards simply incompatible with the KRAZR? or is their a way to make this work? Any help would be greatly appreciated.
Sounds like your card is too big, my understanding is that the early versions of these phones can hold up to 1 gig of memory, a 2 or bigger will lock it up. Also ensure that the card has been formatted, if you have a card reader available, try formatting the card prior to putting it into the phone, this may help.
the krazr can handle up to 2gb i have a two gig in mine. sounds to me like you need to replace the sim card holder. that and the memory card hold in the same slot.
