If i switch iphone 4 sim card into iphone 5c will it transfer my files?

I'm upgrading my iphone 4 to iPhone 5c tomorrow and I have t mobile so I have a SIM card for it, when I put my SIM card into my new iPhone 5c will it transfer my files such as ; music, photos, contacts, etc?

No it won't. The sim card only transfers contacts. In order to transfer your music, photos, etc. Back it up with iTunes then transfer all your stuff to the new phone.

No, sim card will only transfer your contacts. Make sure to export your contacts to the sim

No, it won't. IPhone does not store that data on the SIM card.

Sync the 4 with iTunes on your PC. After the new phone is activated, restore to the 5. Done

No, it will not transfer your files. You need to do that by yourself. I used to transfer my data between my iPhone 4 and iPhone 5s with this Phone to Phone transfer, works fairly well, you may give it a trial. Hope it helps. Contact me if you have any other question. Hope it helps.
