The iPhone doesn’t let you copy contacts from your phone’s address book to your iPhone’s SIM card. But that doesn’t mean you can’t back up your contacts. You just have to do it another way. Here’s what you need to know.

The iPhone doesn't store any data like contacts on the SIM card. It doesn't need to and it doesn't fit Apple's philosophy of how users should use their data.

Older mobile phones stored data on the SIM card because there was no standard, easy way to back up or transfer data to new phones. Eventually SD cards came along, but not every phone had them.

There are two backup options for iPhone, however: a backup is created every time you sync your iPhone with your computer, and you can back up your iPhone data to iCloud.
