To put the memory card in you just push it in, there is a little picture the show which way the card goes in, and you just push it in, to remove it you push the little tab away from the card while sliding the card out at the same time. It is hard to remove, but its not hard to figure it out. If you don't know how to insert or take out the card, then how do you manage a cell phone. But like I said its hard to take out if you have big fingers. Find someone with nails and its easy lol
Your phone already has a 256Mb card in it, you need to remove that before you can put another one in. There's a little plastic tab with a hook that fits in a notch on the card, that has to be held aside while you pull out the card. Total PITA.
