在 iPhone、iPad 或 iPod touch 上发送短信时，您是否一直收到“无法发送消息：需要启用 iMessage 才能发送此消息(Cannot Send Message: iMessage needs to be enabled to send this message)”的通知弹出窗口？我们将向您展示如何解决该问题。
“ iMessage 需要启用(iMessage needs to be enabled)”错误可能会出现在 iPhone 的消息(Messages)应用程序中，原因有多种。尽管可能只是您的 iPhone 未启用 iMessage（好吧，这将是一个非常简单的修复），但它通常是服务器端问题、不正确的 iMessage 设置或损坏的网络配置等其他问题。
完成本故障排除指南中的解决方案，您应该能够修复 iPhone 上的“需要启用 iMessage”错误。
1. 在你的 iPhone 上启用 iMessage
如果在新的 iPhone 或 iPad 上出现“需要启用 iMessage”错误，则可能是 iMessage 在您的设备上未激活。要激活它们：
- 在 iOS 或 iPadOS 设备上
打开“设置”应用。(Settings)
- 向下滚动并点按消息。
- 打开iMessage旁边的开关，等待“等待激活”状态消失；激活 iMessage 最多可能需要一分钟。
由于 iMessage 与FaceTime密切相关，因此最好确保后者也处于活动状态。为此，请返回上一屏幕，点击FaceTime ，然后启用(FaceTime)FaceTime旁边的开关。

2. 检查Apple iMessage服务器状态(Server Status)
如果 iMessage 已经激活，则服务器端的 Apple 消息服务可能有问题。要找出答案，请打开Safari并访问 Apple 系统状态页面(visit the Apple System Status page)。
如果 iMessage 出现故障（如果是这种情况，您会在其旁边看到一个红点），请等待Apple解决该问题。应该不会花很长时间。
3. 强制退出和重新启动消息(Relaunch Messages)
接下来，强制退出消息(Messages)应用程序，重新打开它，并检查这是否会使“需要启用 iMessage”消失。要做到这一点：
- 从屏幕底部向上滑动(Swipe)（如果您的Apple设备有主屏幕按钮，则双击主屏幕按钮）以打开(Home)App Switcher。
- 滑开消息卡。
- 退出主屏幕(Home Screen)并重新启动消息(Messages)应用程序。
4.排除本地连接问题(Local Connectivity Issues)
有时，“需要启用 iMessage”错误可能会由于网络连接的小问题而弹出。以下是一些尝试的建议：
- 打开飞行模式(Airplane Mode)，然后关闭。
- 重新启动您的 Wi-Fi 路由器。
- 切换 Wi-Fi 连接。
- 从Wi-Fi切换到蜂窝数据，反之亦然。
- 移动(Move)到蜂窝信号强度更好的区域。
- 取出并重新插入SIM卡（仅限 iPhone）。
5. 重启你的 iPhone 或 iPad
如果强制退出并重新启动“信息(Messages)”应用程序没有帮助，请尝试重新启动您的 iPhone。每隔一段时间(Every)，需要重新启动以解决本机和第三方应用程序的意外问题。
- 同时按住提高音量和侧面(Side)按钮，直到看到滑动(Slide)关机屏幕(Off)。仅当您的 iPhone 或 iPad 有主(Home)屏幕按钮时才按住侧边(Side)按钮。
- (Swipe)沿着幻灯片向右滑动电源(Power)图标。
- 等待 30 秒并按住侧边(Side)按钮，直到您看到Apple标志。
6. 关闭并重新打开 iMessage
关闭iMessage(Toggle)和FaceTime，然后再打开。通常，这有助于解决导致出现“需要启用 iMessage”错误的持续性问题。
- 前往Settings > Messages并关闭 iMessage 旁边的开关。
- 重新启动你的 iPhone。
- (Head)返回“设置”(Settings)应用并重新激活 iMessage
。
7. 注销并重新登录 iMessage
注销并重新登录 iMessage 是解决 iPhone 上“需要启用 iMessage”错误的另一个方法。要做到这一点：

轻点您的Apple ID 。
- 选择注销。
- 重新启动你的 iPhone。
- 再次前往Settings > Messages > Send和接收(Receive)” ，然后点击“使用(Use)您的Apple ID获取 iMessage”>“登录(Sign)”以使用您的 Apple ID 登录您的iPhone(Apple ID)。如果您有用于 iMessage 的不同 iCloud 帐户，请轻点“使用(Use)其他Apple ID ”并使用正确的凭据登录。
8.删除(Delete)和创建新对话(Create New Conversation)
有时，对话线程可能会损坏，修复“需要启用 iMessage”错误的唯一方法是启动一个新的对话线程。
- (Swipe)向左
滑动对话线程。
- 点击垃圾桶图标。
- 点击屏幕右上角的新消息(New Message)按钮，与联系人创建新对话。
9.激活发送短信
确保(Make)您的 iPhone 可以选择通过SMS发送短信，以防 iMessage 不可用。为此，请转到Settings > Messages。然后，向下滚动 iMessage 设置列表并打开以短信形式(SMS)发送(Send)旁边的开关。
10. 更新你的 iPhone 或 iPad
主要 iOS 和 iPadOS 更新的早期版本（例如 iOS 16.0）通常包含恼人的错误，这些错误会导致第一方应用程序（如消息(Messages)）出错。安装较新的增量更新是修复它们的最佳方法。
要更新您的 iPhone 或 iPad：
- 前往Settings > General > Software Update。
- 等到(Wait)您的 iPhone 扫描更新的软件更新。
- 点击下载并安装。
11.将网络设置重置(Reset Network Settings)为出厂默认设置(Factory Defaults)
如果损坏的网络配置导致“需要启用 iMessage”错误，修复它的唯一方法是重置您的 Wi-Fi 和蜂窝网络设置。如果你想继续：

如果上述修复都无法帮助修复“需要启用 iMessage”错误，您必须联系 Apple 支持(contact Apple Support)。他们应该能够提供更多修复程序来帮助解决问题。同时试用这些适用于 iPhone 的第三方消息传递应用程序(third-party messaging apps for the iPhone)。
11 Ways to Fix iMessage Needs to Be Enabled Error on iPhone
Dо you keep receiving a “Cannot Send Message: iMessage needs to be enabled to send this message” notification pop-up while sending text messages on your iPhone, iPad, or iPod touch? We’ll show you how to fix that.
The “iMessage needs to be enabled” error can appear in the iPhone’s Messages app for several reasons. Although it could just be that iMessage is not enabled on your iPhone (well, that would be a pretty easy fix), it’s typically something else like a server-side issue, an incorrect iMessage setup, or a corrupt network configuration.
Work through the solutions in this troubleshooting guide, and you should be able to fix the “iMessage needs to be enabled” error on the iPhone.
1. Enable iMessage on Your iPhone
If the “iMessage needs to be enabled” error occurs on a new iPhone or iPad, it’s likely that iMessage is not active on your device. To activate them:
- Open the Settings app on your iOS or iPadOS device.
- Scroll down and tap Messages.
- Turn on the switch next to iMessage and wait until the “Waiting for activation” status disappears; it may take up to a minute to activate iMessage.
Since iMessage is closely linked to FaceTime, it’s a good idea to make sure that the latter is also active. To do that, head back to the previous screen, tap FaceTime, and enable the switch next to FaceTime.

2. Check Apple iMessage Server Status
If iMessage is already active, there’s probably something wrong with Apple’s messaging service on the server side. To find out, open Safari and visit the Apple System Status page.
If iMessage appears to be down (you’ll see a red dot next to it if that’s the case), wait until Apple resolves the issue. It shouldn’t take long.
3. Force-Quit and Relaunch Messages
Next, force-quit the Messages app, re-open it, and check if that makes the “iMessage needs to be enabled” go away. To do that:
- Swipe up from the bottom of the screen (or double-click the Home button if your Apple device has one) to open the App Switcher.
- Swipe away the Messages card.
- Exit to Home Screen and relaunch the Messages app.
4. Rule Out Local Connectivity Issues
Sometimes, the “iMessage needs to be enabled” error can pop up due to minor niggles with the network connection. Here are a few suggestions to try out:
- Toggle Airplane Mode on, then off.
- Restart your Wi-Fi router.
- Switch Wi-Fi connections.
- Switch from Wi-Fi to cellular data or vice-versa.
- Move to an area with better cellular signal strength.
- Take out and reinsert the SIM card (iPhone only).
5. Restart Your iPhone or iPad
If force-quitting and relaunching the Messages app didn’t help, try restarting your iPhone. Every so often, a reboot is needed to resolve unexpected issues with native and third-party apps.
- Press and hold the Volume Up and Side buttons together until you see the Slide to Power Off screen. Hold the Side button only if your iPhone or iPad has a Home button.
- Swipe the Power icon along the slide to the right.
- Wait 30 seconds and hold the Side button until you see the Apple logo.
6. Toggle iMessage Off and Back On
Toggle iMessage and FaceTime off, and then back on. Usually, that helps resolve persistent issues causing the “iMessage needs to be enabled” error to show up.
- Go to Settings > Messages and turn off the switch next to iMessage.
- Restart your iPhone.
- Head back to the Settings app and re-activate iMessage.
7. Sign Out and Back Into iMessage
Signing out and back into iMessage is another fix for the “iMessage needs to be enabled” error on iPhone. To do that:
- Go to Settings > Messages and tap Send & Receive.
- Tap your Apple ID under your iMessage phone number and email address.
- Select Sign Out.
- Restart your iPhone.
- Head to Settings > Messages > Send & Receive again and tap Use your Apple ID for iMessage > Sign In to log into your iPhone with your Apple ID. If you have a different iCloud account for iMessage, tap Use Other Apple ID and sign in with the correct credentials.
8. Delete and Create New Conversation
Sometimes, a conversation thread can go corrupt, and the only way to fix the “iMessage needs to be enabled” error is to start a new conversation thread.
- Swipe the conversation thread to the left.
- Tap the Trash icon.
- Tap the New Message button at the top right of the screen and create a new conversation with the contact.
9. Activate Send As SMS
Make sure that your iPhone has the option to send text messages over SMS in case iMessage is unavailable. To do that, go to Settings > Messages. Then, scroll down the list of iMessage settings and turn on the switch next to Send as SMS.
10. Update Your iPhone or iPad
Early releases of major iOS and iPadOS updates—e.g., iOS 16.0—often contain annoying bugs that cause errors in first-party apps like Messages. Installing newer incremental updates is the best way to fix them.
To update your iPhone or iPad:
- Go to Settings > General > Software Update.
- Wait until your iPhone scans for newer software updates.
- Tap Download and Install.
11. Reset Network Settings to Factory Defaults
If a corrupt network configuration is causing the “iMessage needs to be enabled” error, the only way to fix it involves resetting your Wi-Fi and cellular settings. If you want to go ahead:
- Open Settings and go to General > Transfer or Reset iPhone > Reset.
- Tap Reset Network Settings.
- Enter your device passcode and tap Reset Network Settings again to confirm.
After the reset procedure, join a Wi-Fi network or use mobile data (your cellular settings will auto-update themselves) and check if iMessage works correctly. If that fails, perform an all-settings reset instead. Repeat the steps above but select the Reset All Settings options in step 3.
No Luck? Contact Apple Support
If none of the fixes above help fix the “iMessage needs to be enabled” error, you must contact Apple Support. They should be able to provide more fixes to help resolve the issue. Try these third-party messaging apps for the iPhone in the meantime.
