Hi, I'm Ben from The Cellphone Broker in San Jose, California. Today, I'm going to show you how to take the SIM card out of your phone. The SIM card is a subscriber identifier module, and there are only a couple of companies that use this little...this little device that goes inside of the phone. What the...what the SIM card does is it gives all the information about your provider to your phone, and it also gives all the information about your phone to your wireless provider. So it's important that you have a SIM card installed. If you don't have a SIM card installed in your phone, it won't let you even turn on the phone or access the full menus. So AT&T, T-Mobile, Boost Mobile, and Nextel are the four companies in the United States that use the SIM card. So I'm going to show you how to do that right now. The first thing you're going to do to remove your SIM card is turn the phone completely off. The phone says it's powering off, and there it is, it's off. Then what I'm going to do is turn it around and remove the battery cover. I'm going to set that aside and I'm going to remove the battery now. Once the battery's removed, you'll usually see a little door right here on the bottom, and what you can do is you stick your thumb right under there and this door pops open. And then there's your SIM card. Your SIM card has some brass contacts right here. Just try to avoid touching that. It's not bad if you do touch it, but just try to avoid doing it because, after a while, the oils on your fingers can build up on there and cause problems to the contacts here in the phone. So to put that back in, as you notice, it has a little notch right here at one corner. Make sure you align that up with the notch in your phone otherwise it will not work properly or it might not even fit properly. And then shut the little door and go back and put all of this stuff back in there. And your phone's ready to go.
