Re: The Sims 3 Online account moved to new e-mail WITHOUT login?

For everything account/serial code related, you need to contact Customer Support.

They can be found here: https://help.ea.com/contact-us

You have the option to contact them by mail, phone or Live Chat. Make sure you have a game, a category and a platform selected for the options to become available.

If the Live Chat option is not active for you, choose US as your country.
