Another bogus call! Does that happen to you? What can you do about all those unwanted calls?
When you receive those calls on an iPhone, you can look at your list of Recents in your phone App; tap the “i” in a circle (see picture on left). The details are displayed. Next, scroll down to “Block this Caller” and tap. Like magic, future calls, text messages and FaceTime calls from this number will no longer bother you. (If you change your mind later, go through the same steps and tap “Unblock this Caller“.)
