I'll try and explain it a little easier if you like. As you were told by razmee209, the iPhone does not store any contact data on the SIM card as other phones use to. This is by design. Contacts are saved in the Contact application on the phone, and can be synced to Address book, or Windows Contacts, or Outlook on the computer. That allows for changes to be made either on the phone or the computer and then synced so both devices have the same information. A newer service is iCloud for Apple, but moving to a non-iOS device limits what you can do. If the new phone supports syncing with the computer and the applications I mentioned above, then no problem. If not, then you need to know what it supports so you can tell how to transfer them. If it will accept a cloud service, one choice is Gmail, which will support downloading your contacts to them, and then transferring to the new device if it supports it. Good luck.
