i purchased used iphone 6s yesterday and i have a problem to creat apple ID because too many IDs already have been created on this iphone so pls do the needful and allow me to creat a new apple ID on this iphone 6s.

Try creating it at https://appleid.apple.com

Do you really want to create a new Apple ID? You already have one - you use it to log in here - and you may already have an iCloud account or be using it in the App or music stores. If you create a new ID it weon't access any of those.

If you really want a new ID you should be able to create it at https:/appleid.apple.com and then sign in to your new phone with it.

I want new Apple ID

This is iPhone 12 not iPhone 6

That makes no difference.

I even created my ID at https://applied.apple.com successfully but couldn’t still sign in on my phone and it says “Too many free account signed on this iPhone
