I updated my iPhone 5c and it is on wifi and no sim card. How can i get the iPhone started again?

You cannot activate an iPhone without a sim. The sim does not have to be

associated with an active cellular account; however, if the iPhone is locked to a

particular wireless provider, the sim must be from that wireless provider.

Borrow an appropriate sim from a friend/relative/co-worker for the few minutes

activation will take. You will need a sim whenever you restore the iPhone or update

the iOS version.
