How to log in your account from different device

There is a way to do it cause I just transferredmine from my iPhone to my pixel 3 android phone. You have to make sure the account is saved to facebook before this will work. I have mine saved to facebook and EA email. What I did is install the game on my android phone and get past the tutorial to the part where you can add your facebook account. I think that’s lvl 4 then log in via facebook but make sure you have facebook installed on your phone and your logged into your facebook before doing this then after you log into your facebook app then start your sims mobile game and get to the part where you can log in via facebook. 

Hope me this works for you as well. @KittySheng
