If you want to blacklist an iPhone, there are a few things you need to do. First, go to the Settings app on your iPhone and select General. From here, scroll down until you see Restrictions and tap on it. Next, you’ll need to add a new restriction. To do this, tap on the + button in the bottom-right corner of the Restrictions screen and select New Restriction. Name your restriction whatever you want and then enter a description of what it will do. In our example, we’re going to blacklist iPhones from being able to make calls or send text messages. Tap on the + button again and select Add Rule. Now, enter the phone number or email address that you want to blacklist in the first field and then tap on the second field to choose which apps will be affected by this rule. In our example, we’re going to blacklist all iPhones from being able to make calls or send text messages from our current phone number or email address. Tap on Done when finished adding rules. ..
