I put the wrong email address on my iCloud and I can't verify it. How do I change it?

I have a iPhone SE and whenever I click on iCloud it just says verifying and won't let me do anything else.

First before doing ANYTHING, make sure to turn off find my iPhone.

Then go to https://appleid.apple.com/ and change your appleid.

Then there will be a number of places you need to log out on your phone and log back in with the correct ID. iCloud, iMessage, Facetime, game center, app store/iTunes to name most.

Then turn FindMyIphone back on.
