What is a sim card?

[Iconoclast]

I want to upgrade my cell phone and I was thinking of getting one on ebay. It says all I need is a sim card. Do I have one? Where does one get such a thing?

You probably have one in your phone depending on the service and how old your current phone is.

I don't know if the SIM card you have in your curent phone will work in the new one, and it is located underneath the battery of your phone. You could contact your service provider for a sim card as well. :)

I have a treo 650. It is about 10 months old. I am thinking of getting a treo pro. Can I take out this card thingy and just put it into the new phone, and bingo, it will work? My service provider is Verizon. They suck.

[jessiehannan]

IT should. You might have to call and tell them that you are using a different model though.

At att you can just switch the sim card but idk how it works with verizon.

it looks like this and is located behind the battery usually

Mine is a different color, but they all have the same shape. I think Verizon is the same.

IDK about the yen, I googled an image and picked that one because it gives you an idea of the size.
