How do I remove contacts on my sim card on iPhone? By accident I imported some contacts to my contacts app in my iPhone. I do not need them there. So, If I need to avoid to import them again  by accident I would like to remove them from my sim. How can I do this?
iOS can't write to your SIM card, so you won't be able to do this on an iPhone. You have two options: find a friend with a phone that can write to SIM cards, install your SIM in their phone and erase it; or, just get a new SIM card from your carrier.
