iMessage 和FaceTime是“正常工作”的(FaceTime)Apple服务的绝佳示例。至少，他们在大多数情况下都是这样做的。有时，您在 iPhone 或Mac(Mac)上首次设置时会遇到激活错误。
例如，iMessage 和FaceTime可能会在激活阶段简单地冻结，并显示“等待激活”消息。或者，他们可能会抛出诸如“激活(Activation)失败”、“身份验证失败”和“激活过程中发生错误”之类的神秘错误。
如果您在iPhone 或Mac上激活或启用 iMessage 和(Mac)FaceTime时遇到问题，请使用以下提示来修复 iMessage 和FaceTime激活错误。
等待 24 小时
在理想情况下，您应该能够在几秒钟内激活 iPhone 上的iMessage 和FaceTime 。但是，如果您在几分钟内继续看到“等待激活”消息，您可能希望给它更多时间。(Waiting)事实上，Apple建议等待 24 小时！
因此，请将此页面添加为书签，如果相同的消息（或其他与激活相关的错误）在第二天仍然困扰您，请返回。
检查 Apple 服务器状态
如果您在 iPhone 或Mac上激活 iMessage 和(Mac)FaceTime时收到“(FaceTime)激活(Activation)失败”或“无法联系 iMessage 服务器”等错误消息，您可能需要检查Apple服务器的状态以排除任何服务中断。
为此，请前往Apple System Status页面并找到iCloud Account & Sign In、iMessage和FaceTime。如果您看到列出的任何问题，请等到Apple解决这些问题。通常，这应该在几个小时内发生。
排除连接问题
连接问题可能导致 iPhone 和(Connectivity)Mac上出现各种与 iMessage 和 FaceTime 相关的激活错误。尝试(Try)通过以下清单排除它们：
- 在 iPhone 上从Wi-Fi切换到蜂窝数据，反之亦然。

- (Renew the Wi-Fi lease)续订iPhone 或 Mac 上的 Wi-Fi 租约。
- 在Mac(Mac)上禁用和启用 Wi-Fi 。
- 如果可能，请在 iPhone 或Mac(Mac)上切换到不同的 Wi-Fi 网络。

How to Fix iMessage and FaceTime Activation Errors
іMesѕage and FaceTime are great examples of Apple services that “just work.” At least, they do for the most part. Sometimes, you’ll run into activation errors while ѕetting them uр for the first time on your iРhonе or Mac.
For example, iMessage and FaceTime may simply freeze during the activation stage with a “Waiting for activation” message. Or, they could throw out cryptic errors such as “Activation unsuccessful,” “Authentication failed,” and “An error occurred during activation”.
If you’re having trouble activating or enabling iMessage and FaceTime on your iPhone or Mac, use the following tips to fix iMessage and FaceTime activation errors.
Wait for 24 Hours
In ideal conditions, you should be able to activate both iMessage and FaceTime on your iPhone in a matter of seconds. If you continue to see a “Waiting for activation” message for several minutes, however, you may want to give it more time. In fact, Apple recommends waiting for 24 hours!
So, bookmark this page and come back if the same message—or some other activation-related error—keeps bugging you the following day as well.
Check Apple Server Status
If you receive an error message such as “Activation unsuccessful” or “Unable to contact the iMessage server” while activating iMessage and FaceTime on your iPhone or Mac, you may want to check the status of the Apple servers to rule out any service interruptions.
To do that, head over to the Apple System Status page and locate iCloud Account & Sign In, iMessage, and FaceTime. If you see any issues listed, wait until Apple resolves them. Usually, that should happen within a few hours.
Rule Out Connectivity Issues
Connectivity issues can result in all sorts of iMessage and FaceTime-related activation errors on both the iPhone and Mac. Try ruling them out by going through the following checklist:
- Switch from Wi-Fi to cellular data on your iPhone or vice-versa.
- Enable and disable Airplane Mode on your iPhone.
- Renew the Wi-Fi lease on your iPhone or Mac.
- Disable and enable Wi-Fi on your Mac.
- If possible, switch to a different Wi-Fi network on your iPhone or Mac.
- Restart your router.
Restart iPhone/Mac
Sometimes, simply rebooting your iPhone or Mac can fix iMessage and FaceTime-related activation errors. On the iPhone, make sure to disable iMessage and FaceTime—if they’re stuck in the “Waiting for activation” phase—via Settings > iMessage/FaceTime before you restart the device.
Note: On iPhones with Face ID, press and release the Volume Up button, press and release the Volume Down button, and then press and hold the Side button to bring up the Slide to Power Off prompt.
Wireless Carrier Checklist
Your iPhone will attempt to authenticate your mobile number while activating iMessage and FaceTime. If you keep receiving an “Activation unsuccessful” error, for example, here are a few things that you may want to go through:
- Check if your carrier is listed within Apple’s wireless career support pages. If not, contact your carrier and verify that you can send or receive international SMS messages.
- If you have a pre-paid mobile plan, make sure that it has enough credit to send and receive SMS messages.
- Head over to Settings > General > About. If you see a Carrier Settings Update alert, tap Update.
Set Correct Time Zone
You must have the correct time and time zone set up on your iPhone and Mac. If not, you will fail to activate or authenticate iMessage and FaceTime.
Set Time Zone – iPhone
1. Open the Settings app and select General.
2. Select Date & Time.
3. Turn on the switch next to Set Automatically. If your iPhone fails to pick the correct time zone, turn it off and select the correct time zone manually.
Set Time and Time Zone – Mac
1. Open the Apple menu and select System Preferences.
2. Select Date & Time.
3. Select the correct date, time, and timezone using the settings underneath the Date & Time and Time Zone tabs.
Update System Software
Have you updated your iPhone or Mac in a while? iMessage and FaceTime are both integral parts of the operating system, so you may run into issues activating them on older versions of iOS and macOS.
Update iOS
1. Open the Settings app and tap General.
2. Tap Software Update.
3. Install any updates, if available.
Update macOS
1. Open the Apple menu and select System Preferences.
2. Select Software Update.
3. Install any updates, if available.
Change DNS
Try changing the DNS, or Domain Name Service, servers for your Wi-Fi connection on the iPhone or Mac. Google DNS, for example, can help your iPhone or Mac locate Apple’s activation servers without running into issues.
Change DNS – iPhone
1. Open the Settings app and select Wi-Fi.
2. Tap the i-shaped icon next to the active Wi-Fi connection.
3. Tap Configure DNS.
4. Tap Manual.
5. Delete the existing DNS servers and enter the following:
8.8.8.8
8.8.4.4
6. Tap Save.
Change DNS – Mac
1. Press Command+Space to open Spotlight Search. Then, type network and press Enter.
2. Under Wi-Fi, select Advanced.
3. Switch to the DNS tab and replace any existing DNS servers with the following:
8.8.8.8
8.8.4.4
4. Select OK.
Reset Network Settings/Wi-Fi Preferences
You can rule out any corrupted network settings from causing iMessage and FaceTime-related activation errors by resetting the network settings (iPhone) or the Wi-Fi preferences (Mac).
Reset Network Settings – iPhone
1. Open the Settings app and tap General.
2. Tap Reset.
3. Tap Reset Network Settings.
Note: You must manually set up any Wi-Fi connections on your iPhone after the reset procedure.
Reset Wi-Fi Preferences – Mac
1. Open Finder and press Command+Shift+G.
2. Insert the following path and select Go:
/Library/Preferences/SystemConfiguration/
3. Move the following files to the Trash.
- com.apple.airport.preferences.plist
- com.apple.network.identification.plist
- com.apple.network.eapolclient.configuration.plist
- com.apple.wifi.message-tracer.plist
- NetworkInterfaces.plist
- Preferences.plist
4. Enter your user password when prompted.
5. Restart your Mac.
Note: If your Mac runs into any issues connecting to Wi-Fi networks afterward, try restoring the deleted files from the Trash.
Contact Carrier/Apple Support
If none of the fixes above worked, then it’s time to throw in the towel and ring up your carrier (if you’re trying to activate iMessage and FaceTime on the iPhone) or contact Apple Support. They should be able to help you get through the activation phase by suggesting fixes relevant to your device and region.
