根据FCC的数据，到 2020 年，美国居民每月(4 billion robocalls per month)收到近40 亿个机器人电话，即每年 480 亿个。如果人们每次通话只花一秒钟看一眼他们的手机，那仍然是 1522 年的累计浪费时间。
没有人喜欢电话推销员、未知号码或讨厌的前任(telemarketers, unknown numbers, or pesky exes)。好消息是你可以反击。Apple使 iOS 上的呼叫阻止和识别变得容易。呼叫阻止是一项简单的任务，可以为您省去很多麻烦，而且只需轻点几下即可。
如何阻止最近(Block Phone Numbers From Recent)来电者
的电话号码
您不必通过呼叫者 ID(through caller ID)筛选不需要的呼叫。相反，您可以在手机的设置中自动执行此操作。
- 点击(Tap Phone)主屏幕上的电话以打开您的通话清单。
- 您可以从最近(Recent)通话列表、联系人列表(List)或语音邮件(Voicemail)中阻止某人。点击(Tap Recents)屏幕底部的“最近”。
- 点击通话日期右侧的“i”图标。这将显示有关号码或联系人的信息。
- (Tap Block)点击屏幕底部的阻止此呼叫者。(Caller)它将以红色文本显示，而其他选项以蓝色文本显示。
- 将出现一个弹出窗口，警告您将不再接听电话、信息或FaceTime通话。点击阻止联系人(Tap Block Contact)。
执行此操作后，阻止(Block)此呼叫者(Caller)选项将消失并变为蓝色。如果您希望以后能够再次联系此号码，只需选择取消阻止(Unblock)此呼叫者(Caller)。
如何在 iMessage
中阻止 iPhone 上的电话号码(Block Phone Numbers)
也许您的问题不在于来电(with incoming calls)，而在于垃圾短信。您还可以阻止来自 iMessage 的人。
- 打开违规消息，然后点击屏幕顶部的数字。
- 点击信息。
- 点击阻止此来电者。
- 点击阻止联系人。
这类似于您如何阻止来自最近呼叫者的呼叫。
如何通过Facetime阻止电话号码(Block Phone Numbers)
通过Facetime屏蔽号码类似于通过电话(Phone)应用程序或 iMessage 屏蔽号码。
- 打开 Facetime。
- 点击要阻止的号码旁边的“i”。
- 点击阻止此来电者。
- 点击阻止联系人。
简单明了。需要注意的一点是，一个人的Facetime ID可能与他们的SMS或呼叫者 ID 不同。如果他们使用Facetime的电子邮件地址但使用电话号码进行通话，您可能必须同时屏蔽这两个地址才能完全摆脱问题。
您还可以选择仅在使用Wi-Fi时允许(Wi-Fi)Facetime通话。如果您未连接到Wi-Fi ，电话将无法接通。
如何过滤未知邮件
坏消息是robocalls变得越来越聪明。他们通过欺骗号码（甚至是您自己的号码）与您联系，因此阻止个别号码并不总是有效。虽然您不能始终防止来自联系人的欺骗性电话，但您可以摆脱随机消息。
- 打开设置应用程序。
- 点击消息。
- 向下滚动(Scroll)并点击过滤未知发件人(Filter Unknown Senders)的切换按钮。
这不会消除问题，但会为不在您联系人中的任何人创建单独的消息列表。这样可以轻松排序和删除您不想要的对话。
如何停止来自未知号码的呼叫(Calls From Unknown Numbers)
自动电话呼叫者经常联系的一种方式是通过未知号码。虽然Apple和Android在识别和自动静音垃圾电话方面取得了很大进展，但您可以更进一步，将任何未知号码静音。
- 转到设置 > 电话。
- 点击静音未知呼叫者。
- 点击切换开关以启用该功能。
您仍会收到这些电话，但它们会直接转到语音信箱并出现在您的“最近通话”列表中。
在相关说明中，您可以打开“请勿打扰(Disturb)”以使来电静音。就是这样。
- (Swipe)从屏幕右上角向下
滑动。
- 点击半月形图标以激活请勿打扰(Disturb)。这将在活动时使所有通知静音，除了您专门设置为允许的任何通知。
如何在 Mac 上屏蔽号码
如果您在Mac上收到一条最好不要阅读和删除的消息，您可以屏蔽该号码。
- 选择对话。
- 在屏幕顶部，选择Conversations > Block Person。
- 将出现一个确认屏幕，询问您是否确定。如果是，只需选择阻止(Block)将该号码添加到您的阻止列表中。
如何解锁号码
阻止一个号码后立即解除阻止(unblock a number)很容易，但是以后呢？如果您决定需要联系已屏蔽的人，您可以查看屏蔽列表中的所有屏蔽号码。
- 打开设置。
- 点击电话。
- 选择阻止的联系人。
- (Swipe)在屏幕上完全向左滑动以取消阻止该号码
。
- 或者，点击编辑(Edit)并点击数字旁边的减号图标，然后点击取消阻止(Unblock)。
- 点击完成。
我们都意外地阻止了一个号码，无论是通过摸索手指还是在愤怒的时刻。他们很容易解除封锁，这是一件好事。
不过，这并不是你能做的全部。报告垃圾电话和信息确实有效；在收到足够多的报告后，AT&T 或Verizon等运营商将联系该号码的所有者进行调查。如果这不起作用并且您对 iOS 中的内置过滤器不满意，您可以从App Store下载第三方垃圾邮件拦截器。
未知的电话很烦人，但你不必默默地忍受它们。屏蔽你能屏蔽的号码，过滤那些你不能屏蔽的号码，并享受每天相对较少的垃圾电话。
How to Block Phone Numbers on Your iPhone
According to the FCC, US residents received almost 4 billion robocalls per month in 2020. That’s 48 billion per year. If people only spared a single second per call to glance at their phone, that’s still a whopping 1,522 years of cumulative wasted time.
No one likes telemarketers, unknown numbers, or pesky exes. The good news is that you can fight back. Apple makes call blocking & identification easy on iOS. Call blocking is a simple task that can save you a lot of headaches, and it only takes a few taps.
How to Block Phone Numbers From Recent Callers
You don’t have to screen unwanted calls through caller ID. Instead, you can do this automatically in your phone’s settings.
- Tap Phone on your home screen to open your call list.
- You can block someone from your Recent call list, from your Contacts List, or from Voicemail. Tap Recents at the bottom of the screen.
- Tap the “i” icon to the right of the call date. This will bring up information about the number or contact.
- Tap Block this Caller at the bottom of the screen. It will be in red text versus the other options in blue text.
- A pop-up appears warning that you will no longer receive phone calls, messages, or FaceTime calls. Tap Block Contact.
Once you do this, the Block this Caller option disappears and changes to blue. If you want to be able to contact this number again in the future, just select Unblock this Caller.
How to Block Phone Numbers on iPhone in iMessage
Maybe your problem isn’t with incoming calls but spam text messages. You can also block people from iMessage.
- Open the offending message, then tap the number at the top of the screen.
- Tap Info.
- Tap Block this Caller.
- Tap Block Contact.
It’s similar to how you would block calls from recent callers.
How to Block Phone Numbers Through Facetime
Blocking a number through Facetime is similar to blocking through the Phone app or iMessage.
- Open Facetime.
- Tap the “i” beside the number you want to block.
- Tap Block this Caller.
- Tap Block Contact.
Simple and straightforward. One thing to note is that a person’s Facetime ID might not be the same as their SMS or caller ID. If they use an email address for Facetime but a phone number for calls, you might have to block both to rid yourself of the problem completely.
You can also choose only to allow Facetime calls when on Wi-Fi. The calls won’t come through if you’re not connected to Wi-Fi.
How to Filter Unknown Messages
The bad news is that robocalls are getting smarter. They spoof numbers (even your own) to contact you, so blocking individual numbers doesn’t always work. While you can’t always protect against spoofed calls from your contacts, you can rid yourself of random messages.
- Open the Settings app.
- Tap Messages.
- Scroll down and tap the toggle for Filter Unknown Senders.
This won’t eliminate the problem, but it will create a separate list of messages for anyone not in your contacts. This makes it easy to sort and delete conversations you don’t want.
How to Stop Calls From Unknown Numbers
One way robocallers often reach out is through unknown numbers. While Apple and Android have made many strides in identifying and automatically silencing spam calls, you can take it a step further by silencing any unknown numbers.
- Go to Settings > Phone.
- Tap Silence Unknown Callers.
- Tap the toggle to enable the feature.
You’ll still receive these calls, but they will go straight to voicemail and appear in your Recents list.
On a related note, you can turn on Do Not Disturb to silence incoming calls. Here’s how.
- Swipe down from the top-right corner of the screen.
- Tap the half-moon icon to activate Do Not Disturb. This will silence all notifications while active, except for any you have specifically set to allow.
How to Block a Number on Mac
If you’re on your Mac and receive a message that’s better left unread and deleted, you can block that number.
- Select the conversation.
- At the top of the screen, select Conversations > Block Person.
- A confirmation screen will appear asking if you’re sure. If you are, just select Block to add that number to your block list.
How to Unblock a Number
It’s easy to unblock a number immediately after you block it, but what about later down the line? If you decide that you need to reach someone you’ve blocked, you can view all blocked numbers in your block list.
- Open Settings.
- Tap Phone.
- Select Blocked Contacts.
- Swipe left completely across the screen to unblock that number.
- Alternatively, tap Edit and tap the minus icon beside the number and then tap Unblock.
- Tap Done.
We’ve all accidentally blocked a number, either through fumbling our fingers or in a moment of anger. It’s a good thing they’re so easy to unblock.
That’s not all you can do, though. Reporting spam calls and messages does work; after enough reports, carriers like AT&T or Verizon will contact the owner of the number to investigate. If that doesn’t work and you’re unsatisfied with the built-in filters in iOS, you can download third-party spam blockers from the App Store.
Unknown calls are irritating, but you don’t have to silently suffer through them. Block the numbers you can, filter those you can’t, and enjoy the relatively lower number of spam calls that come through each day.
