Why Block Numbers? 

The answers to this simple question may constitute a long list. Blocking calls certainly stands as a solution to a problem that harasses many people. Due to unwanted calls, many people have had to change their phone numbers, which can cause them to miss out on important calls. Reasons for considering call blocking include: 

  • Your peace is disrupted by unwanted calls from telemarketers, among others. You may be deprived of your sleep or be disturbed in a meeting or some other important and private activity with a call that is not worth your attention.
  • You are harassed by someone who should not have your number but who unfortunately does. Call blocking shuts unwelcome callers off so you don't have to change your number.

Even if you don't block a caller, you can handle your calls in a smart way that makes good use of your time. For example, you may choose to divert some calls to voicemail, reply to some others with messages, and channel others to other numbers (this feature is called call forwarding).
