Contact groups are a great way to manage contacts that you may have related in some manner. Once created, removing them from your phone has never been easier! However, if iOS 7 users want to access and management of these sorts on their device itself they will need to sign in to iCloud using computer browser software instead though there’s no problem whatsoever doing this remotely so long as the person who creates or requests an item also signs out before accessing anything else over network connection boundaries (away).
Once signed into your iCloud account follow these steps to delete a contact group:
1. Open Contacts on the main iCloud menu.
2. Click once on the group you wish to delete.
3. Tap the delete key on the keyboard.
4. When the confirmation pop-up window appears, click on delete to finish.
The contact group has been deleted, but its individual members can still be found in All Contacts. Changes will sync to all devices that are connected with your iCloud account.
