Apple Recommended post by Roger Wilmut1, March 2018 in response to "Re: how to solve maximum no of free account the phone" - https://discussions.apple.com/message/33209658#message33209658 - "Any one device can create only three new iCloud accounts, and there is no way round that. However, what you can do is to create a new iCloud account on another iOS device or Mac (not Windows or android). Then you will be able to sign into that account on the original phone."
