Re: how to change the language in sims 4?
@marysowa and @DrateGon You could try contacting EA customer support and asking that the language locked version of Sims 4 be removed from your account and the global version added instead. Support will sometimes do this if you get a live chat (not email). If you don't see the option to live chat, change the location in your browser window to U.S. or U.K., or choose a slightly different category of issue.

The other option is to download the game from Steam, which only offers the global version. Your EA-owned packs would work in the Steam install: you'd install them from the EA App after you installed the base game in Steam.
