Have spectrum, with active, iCloud, AOL, google. When we turned in our equipment with Comcast the account dropped off, 2 months later, I signed in and it reactivated..no idea why. Always used Comcast for those you won a car if you give us your email. My iCloud is for important emails. We could keep same phone number if we choose to switch.
Bonus leave junk e-mail with Comcast and switch everything else to new account.
