Grouping your contacts makes navigating them on iPhone much easier and allows you to message and email a multitude of contacts at once by allowing you to simply use the name of the group rather than typing in each individual every time. Unfortunately there is no way to do this on the iPhone itself without a third-party app. Apple prefers you to use iCloud to make contact groups which, once you created, will sync across all of your devices. Here’s how to make a contact group with iCloud: Log into iCloud on a computer. Open Contacts and click on the “+” button in the bottom left.
