Were you aware that you have the ability to block unknown callers on an iPhone? That’s correct! There’s actually a concealed feature specifically designed to help you swiftly silence those bothersome spammers with just a few effortless taps.
From bothersome telemarketers to dubious phone scams, most of us have likely encountered a considerable number of unwanted calls at some point. With unsolicited phone calls becoming more prevalent and annoyinh, this handy trick discovered in your Settings can truly be a blessing.
Before we delve into the details, it’s worth noting that this particular iOS feature rejects calls from any unknown numbers. Hence, it’s essential to remember that once you activate this setting, any number not saved in your contacts will be automatically silenced, regardless of whether it displays a caller ID.
Instead, any calls from unknown numbers will be routed to your voicemail and listed in your Recents section. This means that if a family member acquires a new phone number and needs to get in touch with you, you’ll still be able to retrieve their contact information when needed.
iPhone users will also find it beneficial to know that this feature occasionally permits unknown callers if their number is associated with a recent outgoing call or if it’s a number extracted from an email or text message recognized by Siri Suggestions. This functionality can be quite useful when a loved one or an acquaintance genuinely needs to get in touch with you, ensuring you don’t miss their important calls while still filtering out persistent salespeople or unwanted retailers.
Keeping this small consideration in mind, if you’re tired of receiving those mysterious ‘No Caller ID’ calls on your iPhone, simply follow these three steps to effectively silence those bothersome spammers.
