The iPhone saves SIM card data using the device’s hard drive. However, you can use the SIM card from another cell phone to transfer your contacts to your new iPhone. The process only works when you transfer from a non-iPhone device that uses the same type of SIM card. Make sure that the old and new SIM cards use the same physical form to prevent the card from getting stuck in your iPhone. Once you import your contacts, you may need to manually edit some of the contacts if you notice duplicate numbers. Tips Warnings Writer Bio
