How to get Apple Care from Sprint?

Okay so I'm eligible for an upgrade. I'm upgrading my iPhone 4S to the 5s.sprint is my carrier. I was reading up on sprints insurance and apples insurance. Does sprint not offer apple care up front anymore? When I buy my iphone would I have no insurance on it then drive to the apple store with my purchase info and buy apple care there? Someone please confirm.

Generally when you upgrade you would be offered AP+ by Sprint. If they don't then ask about it. AppleCare+ is superior to all the carrier insurance plans offered by any carrier. And carrier plans suck as you pay into them but when something happens they tell you to get ahold of Apple anyway.

You could go to an Apple store. You could also call Apple and purchase it over the phone. Apple will run a remote diagnostics on your phone and if it checks out will proceed.
