In this tutorial, we learn how to remove the SIM card out of an iPhone. First, turn your phone all the way off, then insert a pin into the top hole next to the circular button. Insert this until the SIM card pops out of the hole next to it. There will be a cover along with it, just set this aside. Now, your phone will tell you that there is no SIM card located in your phone. You can replace this with another SIM card or put yours back in. This is the most simple way to take out your card, so use this anytime you want to switch phones!
