If you’re an iPhone user and use iMessage to communicate with friends and family, it’s important to be sure you’re registered for the service. To do so, you’ll need to create a new Apple ID and password. Once you’ve registered, you can’t use iMessage until you’ve updated your account information. To uninstall iMessage on your iPhone, follow these steps:

  1. Open the Settings app and select Message & Contacts.
  2. Scroll down and select the account that you want to uninstall from iMessage.
  3. Tap Remove Account and confirm your deletion by tapping OK.
