有时，阻止来自电话营销公司(blocking unwanted calls from telemarketing companies)、未知号码和联系人中某些人的不需要的电话可以让您高枕无忧。但是，如果您在此过程中不小心阻止了朋友怎么办？或者，您想取消阻止某人但不记得它是如何完成的？本教程将引导您完成在 iOS 和Android设备上解锁号码的过程。
注意：(Note:)本教程中的步骤可能会根据您的设备型号（主要适用于Android）及其操作系统版本而有所不同。我们使用了运行Android 10操作系统（带有库存 UI）的(Android 10)诺基亚(Nokia)智能手机和安装了 iOS 14.7.1 的 iPhone。运行自定义Android UI的(Android UI)Android 设备(Android devices)（来自Samsung、OnePlus等）可能有不同的取消阻止联系人的步骤。如果以下方法均不适用于您的设备，请访问制造商的网站以获取明确的说明。
在 iPhone 上解锁号码
如果您记得您阻止的联系人，您可以轻松地从电话(Phone)应用程序中取消阻止他们。但是，如果您无法调用联系人，请检查“电话(Phone)设置”菜单中的已阻止号码列表并相应地取消阻止它们。
在本节中，我们将向您展示在 iPhone 和 iPad 上解锁联系人的不同技术。
1.从电话应用程序中取消阻止联系人(1. Unblock a Contact from the Phone App)
启动电话(Phone)应用程序，点击您要取消阻止的号码旁边的信息图标，然后点击取消阻止此呼叫者(Unblock this Caller)。
如果联系人不在“最近”部分，请前往联系人(Contacts)选项卡，选择要取消阻止的联系人（使用搜索栏更快地找到联系人），然后选择取消阻止此呼叫者(Unblock this Caller)。
2.从设置菜单中取消阻止联系人(2. Unblock Contacts from the Settings Menu)
如果您想粗略查看 iPhone 上所有被阻止的联系人，这是最好的方法。
- 打开设置(Settings)应用程序，选择电话(Phone)，然后选择阻止的联系人(Blocked Contacts)。
- 点击右上角的编辑(Edit)。
- 点击要取消阻止的联系人左侧的减号图标，然后选择取消(minus icon)阻止(Unblock)。这将取消阻止号码并将其从阻止的联系人列表中删除。点击完成(Done)以保存更改。
附录：取消静音未知呼叫者(Addendum: Unmute Unknown Callers)
iOS 和 iPadOS 附带一项功能，可自动将呼叫从未知/未保存的号码转移到语音邮件。将其视为“软块”。如果您没有接到来自您没有阻止的号码的电话，则“静音未知呼叫者”功能可能处于活动状态。
前往Settings > Phone > Silence Unknown Callers并关闭Silence Unknown Callers。
在 Android 上解锁号码
如果您在Android设备上屏蔽了某个号码并且想要恢复该操作，则有不同的方法可以解决。
1.从通话记录中取消阻止一个号码(1. Unblock a Number from the Call Log)
手机通话记录中被屏蔽的号码或联系人将显示一个划掉的图片，即一个圆圈，其中有一条线穿过它。要取消阻止联系人/号码，点击它，选择取消阻止(Unblock)图标，然后在确认提示上再次点击取消阻止。(Unblock)
或者，点击打叉的显示图片(crossed-out display picture)，点击三点菜单图标(three-dot menu icon)，然后选择取消阻止号码(Unblock numbers)。
2. Unblock Number/Contact from the Phone Settings Menu
如果被阻止的联系人不在您的通话记录中，请转到拨号器设置菜单以取消阻止该号码。
- 启动电话应用程序，点击右上角的三点菜单图标(three-dot menu icon)，然后选择设置(Settings)。
- 选择屏蔽号码(Blocked numbers)。
- 点击要取消阻止的号码旁边的x图标，然后在提示中选择取消阻止。(Unblock)
您还应该关闭“阻止(Block)来自身份不明的呼叫者的呼叫”选项。这将自动取消阻止来自不在您的联系人列表中的号码的呼叫。
3. Unblock Number/Contact from the Google Contacts App
如果您的Android(Android)设备上的本机拨号器应用程序没有用于查看已阻止联系人的菜单，您可以从“联系人(Contacts)”应用程序中取消阻止号码。
- 启动通讯录，点击左上角的汉堡菜单图标(hamburger menu icon)，然后选择设置(Settings)。
- 前往“管理(Manage)联系人”部分并选择已屏蔽号码(Blocked numbers)。
- 点击被阻止号码旁边的x 图标(x icon)，然后在提示上选择取消阻止。(Unblock)
4. Unblock Number/Contact from the Messages App
当您将SMS或MMS报告为垃圾邮件时，Android会将号码添加到被阻止的联系人列表中。以下是如何检查通过默认消息应用程序(default Messages app)阻止的号码以及如何取消阻止它们的方法：
- 打开消息应用程序，点击三点菜单图标(three-dot menu icon)，然后选择垃圾邮件和阻止(Spam and blocked)。
- 从您要取消阻止的号码/联系人中选择对话，然后在下一页上选择取消阻止。(Unblock)
使用第三方应用程序取消阻止联系人(Unblock Contacts Using Third-Party Apps)
如果您通过第三方来电显示应用(third-party caller ID apps)屏蔽了某个联系人，您可能不会收到此人的电话或短信，即使该号码不在您设备的屏蔽联系人列表中。在应用程序上查看联系方式，或在应用程序的设置菜单中打开被阻止号码列表并取消阻止该号码。
更好(Better)的是，将设备随附的系统电话应用程序设为电话的默认应用程序。
前往设置(Settings)>应用和通知(Apps & notifications)>默认应用(Default apps)>手机应用(Phone app)，然后选择系统默认的Android手机应用。
根据需要阻止和取消阻止号码
重要的是要说明阻止和取消阻止号码是特定于设备的操作。将您的SIM 卡(SIM card)切换到另一台设备是解锁号码的一种简单且间接的方法。
将您的 iPhone 或 Android 智能手机重置(Resetting your iPhone or Android smartphone)为出厂默认设置也将清除被阻止的联系人列表并取消阻止所有号码。虽然这很极端——因为你会丢失你的文件和设置——但它是取消阻止联系人的有效方法，我们将它放在那里是为了教育目的。

How to Unblock a Number on iPhone and Android
Ѕometimeѕ, blocking unwanted calls from telemarketing companies, unknown numbers, and certain people in your contacts could bring you peace of mind. But what if you accidentally blocked a friend in the process? Or, you want to unblock someone but can’t remember how it’s done? This tutorial will walk you through the process of unblocking a number on iOS and Android devices.
Note: The steps in this tutorial may vary based on your device model (mainly for Android) and its operating system version. We utilized a Nokia smartphone running Android 10 OS (with stock UI) and an iPhone with iOS 14.7.1 installed. Android devices (from Samsung, OnePlus, etc.) running custom Android UI may have different steps for unblocking contacts. If none of the methods below apply to your device, head to the manufacturer’s website for clear-cut instructions.
Unblock a Number on iPhone
If you remember the contact(s) you blocked, you can easily unblock them from the Phone app. But if you can’t recall the contact(s), check the list of blocked numbers in the Phone settings menu and unblock them accordingly.
In this section, we’ll show you different techniques to unblock contacts on your iPhone and iPad.
1. Unblock a Contact from the Phone App
Launch the Phone app, tap the info icon next to the number you want to unblock, and tap Unblock this Caller.
If the contact isn’t in the “Recents” section, head to the Contacts tab, select the contact you want to unblock (use the search bar to locate the contact faster) and select Unblock this Caller.
2. Unblock Contacts from the Settings Menu
This is the best approach to follow if you want to have a cursory view of all blocked contacts on your iPhone.
- Open the Settings app, select Phone, and select Blocked Contacts.
- Tap Edit at the top-right corner.
- Tap the minus icon to the left of the contact you want to unblock and select Unblock. That’ll unblock the number(s) and remove it from the list of blocked contacts. Tap Done to save the change.
Addendum: Unmute Unknown Callers
iOS and iPadOS ship with a feature that automatically diverts calls from unknown/unsaved numbers to voicemail. Think of this as a “soft block.” If you aren’t receiving calls from numbers you didn’t block, the “Silence Unknown Caller” feature is probably active.
Head to Settings > Phone > Silence Unknown Callers and toggle off Silence Unknown Callers.
Unblock a Number on Android
If you blocked a number on your Android device and you want to revert the action, there are different ways to go about it.
1. Unblock a Number from the Call Log
A blocked number or contact in your phone’s call log will have a crossed-out display picture, i.e., a circle with a line through it. To unblock the contact/number, tap on it, select the Unblock icon and tap Unblock again on the confirmation prompt.
Alternatively, tap the crossed-out display picture, tap the three-dot menu icon, and select Unblock numbers.
2. Unblock Number/Contact from the Phone Settings Menu
If the blocked contact isn’t in your call log, head to the dialer settings menu to unblock the number.
- Launch the Phone app, tap the three-dot menu icon at the top-right corner, and select Settings.
- Select Blocked numbers.
- Tap the x icon next to the number you want to unblock and select Unblock on the prompt.
You should also toggle off the “Block call from unidentified callers” option. That’ll automatically unblock calls from numbers that aren’t on your contact list.
3. Unblock Number/Contact from the Google Contacts App
If the native dialer app on your Android device doesn’t have a menu for viewing blocked contacts, you can unblock numbers from the Contacts app.
- Launch Contacts, tap the hamburger menu icon on the top-left corner, and select Settings.
- Head to the “Manage contacts” section and select Blocked numbers.
- Tap the x icon next to the blocked number and select Unblock on the prompt.
4. Unblock Number/Contact from the Messages App
When you report an SMS or MMS as spam, Android adds the number to the list of blocked contacts. Here’s how to check numbers blocked via the default Messages app and how to unblock them:
- Open the Messages app, tap the three-dot menu icon, and select Spam and blocked.
- Select the conversation from the number/contact you want to unblock and select Unblock on the next page.
Unblock Contacts Using Third-Party Apps
If you blocked a contact via third-party caller ID apps, you might not receive calls or texts from the person—even if the number isn’t on your device’s list of blocked contacts. Check the contact details on the app, or open the list of blocked numbers in the app’s settings menu and unblock the number.
Better yet, make the system phone app that shipped with your device the default app for phone calls.
Head to Settings > Apps & notifications > Default apps > Phone app and select the system default Android phone app.
Block and Unblock Numbers as Needed
It’s important to state that blocking and unblocking numbers are device-specific actions. Switching your SIM card to another device is an easy and indirect method to unblock a number.
Resetting your iPhone or Android smartphone to factory default will also clear the list of blocked contacts and unblock all numbers. Although that’s extreme—because you’ll lose your files and settings—it’s a valid method to unblock contacts, and we’re putting it out there for educational purposes.
