@Aphelele See here for a very handy help.

To add to RicoK answer: There sadly is no English version. All you can do it use translators to translate it.

Hi @Aphelele,

Thank you for your message. Good question!

I see that @Groentjuh and @RicoK already informed you correctly about this (thank you guys!). Unfortunately, we do not have the ability to change the language in Mijn Simyo to English. I did forward this request to the relevant department, who knows, maybe this option will be available in the future! 

Kind regards,
Roeqajja
