Use iPhone 5c as iPod with UNACTIVATED SIM card WITHOUT computer?

So my UNACTIVATED SIM card just came in the mail and I didn't realize that my PC graphics card is dead, so I can't access iTunes and I would like to know if there's a way for me to use my iPhone 5c as an iPod with an inactive SIM card. Currently, my iPhone 5c is at the setup screen and I can't get past it with my inactive SIM card.

Not sure why it's not working but it should be able to. My old iPhone 5c is inactive but still works. On Wi-Fi even the calls work…

You need a SIM card to activate the phone. Let your carrier activate the SIM and you can activate. Or if you've access to any other SIM card (parents / friends) from the same carrier, you can use their SIM to activate. Or if the phone is unlocked, you can use any SIM card to activate the phone.
