What to Keep in Mind
注意事项
Before we dive into blocking options, there are a few points to know: 在深入了解拦截选项之前，有几点需要了解：
If possible, don’t answer any calls from numbers you don’t recognize. Callers with anything important to say will likely leave a message anyway. Sadly, this strategy won’t work for many business owners or people who have interests that involve a lot of calls from unknown numbers. 如果可能，不要接听任何陌生号码的来电。如果来电者有重要的事情，他们通常会留言。遗憾的是，对于许多企业主或因工作需要频繁接听陌生号码来电的人来说，这个策略并不适用。
Never click on a link or attachment in a spam text message, because doing so could trigger malware. If possible, avoid opening such texts altogether. 永远不要点击垃圾短信中的链接或附件，因为这样做可能会触发恶意软件。如果可能，尽量完全避免打开此类短信。
Never respond to a spam text message, as doing so will confirm that your number is valid. 永远不要回复垃圾短信，因为这样做会确认你的号码是有效的。
If you are concerned that the call or message might be from a legitimate company, try typing the number into your preferred search engine. While it can be tricky to confirm a scammer’s number, it is easy to verify a legitimate number. If you can’t find any information about the number, be cautious and ignore it. 如果你担心电话或信息可能来自正规公司，请尝试将该号码输入你常用的搜索引擎。虽然确认诈骗者的号码可能比较困难，但验证正规号码却很容易。如果你找不到关于该号码的任何信息，请保持警惕并忽略它。
I’ll explain below how to block numbers, but it’s also important to report unwanted calls and messages. If you’re dealing with telemarketing, a scam, or spam, you can report it to the FTC here. You can also add your number to the Do Not Call Registry, though this only works for sales calls from reputable companies. Sadly, many organizations and scammers ignore it. Below, I will go into how to report numbers to manufacturers, carriers, and third parties. The more that people do this, the easier it will become to identify and preemptively block or label nuisance numbers. 我将在下文解释如何拦截号码，但举报骚扰电话和信息同样重要。如果你遇到电话推销、诈骗或垃圾信息，可以在此处向美国联邦贸易委员会（FTC）举报。你还可以将自己的号码添加到“谢绝来电登记处”（Do Not Call Registry），尽管这仅对正规公司的推销电话有效。遗憾的是，许多机构和诈骗者会无视它。下文我将介绍如何向制造商、运营商和第三方举报号码。这样做的人越多，识别并预先拦截或标记骚扰号码就会变得越容易。
How to Block Calls and Texts on an iPhone
如何在 iPhone 上拦截电话和短信
It’s easy to block individual numbers on your iPhone. Here’s how: 在 iPhone 上拦截单个号码非常简单。方法如下：
- In the Phone app, tap Recents, then tap the number or contact you want to block (or the Information icon in Classic view). Scroll down and tap Block Caller. 在“电话”应用中，点击“最近通话”，然后点击你想要拦截的号码或联系人（或在经典视图中点击“信息”图标）。向下滚动并点击“拦截此来电者”。
- In the FaceTime app, tap the number, contact, or email address you want to block, then scroll down to tap Block Caller. 在 FaceTime 应用中，点击你想要拦截的号码、联系人或电子邮件地址，然后向下滚动并点击“拦截此来电者”。
- In the Messages app, open the conversation with the contact you want to block, tap the contact at the top, then Block Caller. 在“信息”应用中，打开与你想要拦截的联系人的对话，点击顶部的联系人，然后点击“拦截此来电者”。
Once a caller is blocked, you won’t get notifications when they call or send a message, but they won’t be able to tell that they have been blocked and will still be able to leave voicemails. You can review and unblock callers anytime. To do so, follow this sequence: Open Settings, Privacy & Security, and tap Blocked Contacts. 一旦来电者被拦截，当他们拨打电话或发送信息时，你将不会收到通知，但他们无法察觉自己已被拦截，并且仍然可以留下语音留言。你可以随时查看并解除对来电者的拦截。操作步骤如下：打开“设置”，进入“隐私与安全性”，然后点击“已拦截的联系人”。
How to Filter Unknown Callers and Senders on an iPhone
如何在 iPhone 上过滤未知来电者和发件人
Unfortunately, blocking individual numbers isn’t very effective when telemarketers or scammers are contacting you, as they use multiple numbers and change them frequently. But there is something else you can do to filter unknown callers and senders: 遗憾的是，当电话推销员或诈骗者联系你时，拦截单个号码的效果并不理想，因为他们会使用多个号码并频繁更换。但你可以采取其他措施来过滤未知来电者和发件人：
Open Settings, Apps, Phone, and scroll down to tap Screen Unknown Callers. Then, select Ask Reason for Calling, which requests more information from unsaved numbers before ringing your iPhone, or Silence, which automatically silences calls from numbers not saved in your contacts. They can still leave a voicemail, and the calls will appear in your recent calls list. 打开“设置”，进入“应用”，选择“电话”，向下滚动并点击“静音未知来电者”。然后，选择“询问通话原因”（这会在 iPhone 响铃前要求未保存的号码提供更多信息）或“静音”（这会自动将未保存在通讯录中的号码来电静音）。他们仍然可以留下语音留言，且这些通话会出现在你的最近通话列表中。
You can establish the same process for messages by going to Settings, Apps, Messages, and scrolling down to toggle on Screen Unknown Senders. This will hide notifications and move messages to the Unknown Senders list. You may also want to toggle on Filter Spam here to hide messages from known spam sources. 你可以通过进入“设置”、“应用”、“信息”，然后向下滚动并开启“过滤未知发件人”来对信息执行相同的操作。这将隐藏通知并将信息移至“未知发件人”列表。你可能还想在此处开启“过滤垃圾信息”，以隐藏来自已知垃圾信息源的短信。
If a message looks like spam, you can swipe left without opening it, tap the trash can icon, and then Delete and Report Spam. If you open a message that turns out to be spam, always tap the Report Spam link under the message and then Delete and Report Spam. 如果一条信息看起来像垃圾信息，你可以在不打开它的情况下向左滑动，点击垃圾桶图标，然后选择“删除并举报垃圾信息”。如果你打开了一条信息发现是垃圾信息，请务必点击信息下方的“举报垃圾信息”链接，然后选择“删除并举报垃圾信息”。
How to Block Calls and Texts on an Android Phone
如何在 Android 手机上拦截电话和短信
It’s straightforward to block numbers on an Android phone, too, but the method differs among manufacturers. 在 Android 手机上拦截号码也很简单，但不同制造商的方法有所不同。
On a stock Android device, like a Google Pixel phone, you’ll open the Phone app and tap on the Home tab. Long-press the number you want to block, and then tap Block or Report. You can choose whether to uncheck the box marked Report call as spam or to check the box next to Report call as scam. Either way, you’ll tap Block after selecting. 在原生 Android 设备（如 Google Pixel 手机）上，打开“电话”应用并点击“主页”标签。长按你想要拦截的号码，然后点击“拦截或举报”。你可以选择取消勾选“将通话举报为垃圾信息”框，或勾选“将通话举报为诈骗”旁边的框。无论哪种方式，选择后点击“拦截”即可。
On a Samsung phone, open the Phone app and go to Recents, then tap the number you want to block, then select the Menu icon and tap Block. 在三星手机上，打开“电话”应用并进入“最近通话”，点击你想要拦截的号码，然后选择菜单图标并点击“拦截”。
How to Filter Unknown Callers and Senders on an Android Phone
如何在 Android 手机上过滤未知来电者和发件人
If you are getting a lot of unwanted calls and messages, and the numbers keep changing, you might want to filter out any unknown numbers. Here’s how to do that on an Android: 如果你收到大量骚扰电话和信息，且号码不断更换，你可能需要过滤掉所有未知号码。在 Android 上操作如下：
Open the Phone app and tap the Menu icon, then three vertical lines at the top left, then Settings, Blocked numbers, and finally toggle on Unknown (or Block unknown callers on a Samsung phone). 打开“电话”应用，点击菜单图标（左上角的三个竖线），进入“设置”，选择“已拦截的号码”，最后开启“未知”（或在三星手机上开启“拦截未知来电者”）。
You can also turn on caller ID and spam… 你还可以开启来电显示和垃圾信息拦截……
