It’s not the SIM card with the language setting; it’s the device (the handset). At least, it should be. I just did a quick search and found this PDF user manual in English. If the phone as sold in the Spanish-speaking country where it was originally sold has the option, it seems that pressing and holding the * key will call up the language menu. If it doesn’t, then I’ll venture that the handset doesn’t have more than one language on it.
