How to reset an iPhone passcode? - 1

I got an iPhone 5s for Christmas this year, when I set it up it asked me if I wanted a passcode and I put 'do not add a passcode' and now there's a passcode on my phone and I don't know where it came from. I never put a passcode on my phone.

Is there a way I can reset it?

You have to call your carrier and provide info for them to help you.

If you are the owner of the phone and it has not been reported stolen, you can call apple and they can do it. You will read them the serial number from the phone
