Re: Does chosing the option "redeem a code" instead of "redeem cash card" give me less simpoints?

You should check with EA's customer support if they charged you with anything of if it simply works that way. https://help.ea.com/contact-us

Scroll down the page to the bottom, on the right side choose your country, then scroll back up and fill in the steps, you'll be given ways to contact them for help: a message, live chat or phone number (depending on what country you're in).
