Is there a way to activate iPhone from home if I'm with US Cellular?

So I broke my phone, but found my old phone and figured I'd just switch out the two (nothing's wrong with the old one). How would I need to go about that without actually having to go to a US Cellular store?

You just switch your SIM cards. There's a small door on the side of the phone with a hole. Push a paper clip in to release the SIM card and put it in your old phone. If you need better instructions search for a video on youtube. Otherwise there's dozens of strip mall stores that fix phones now. You really should just get it fixed or sell it as is on eBay. Even a broken iPhone can be worth a few hundred dollars.
