您正试图给某人打电话，但您的电话似乎没有接通，或者他们似乎没有接听。
更糟糕的是，您向他们发送消息，但您不确定他们是否也收到了短信——因为没有回复。
发生这种情况有几个可能的原因：
- 他们的 SIM 卡有问题(Issues with their SIM card)。
- 手机电池没电了(Phone battery is dead)。
- 他们没有信号。
- 他们丢了手机。
- 他们错误地启用了飞行模式(airplane mode)或请勿打扰模式(Do Not Disturb mode)。
- 他们封锁了你的号码。
如果您怀疑此人阻止了您的号码，我们将向您展示您可以在 iPhone 上尝试的不同操作，以确认它是否属实。
如何判断是否有人在 iPhone 上阻止了您的号码(How to Tell If Someone Blocked Your Number on iPhone)
当有人阻止您的号码时，他们将不再收到您的电话或短信。
如果他们阻止您的号码，您将不会收到任何官方警报或通知。但是，如果您打电话后它响了一次或不响并直接转到语音信箱(voicemail)，则您可能已被阻止。
没有简单的过程可以判断是否有人阻止了您。但是，您可以尝试几种不同的方法来检查您是否被阻止。
- 从其他号码拨打，看看他们是否接听。如果您没有足够的通话时间，请了解如何使用 WiFi 拨打手机(how to use WiFi to make cellphone calls)。如果您致电并在几天内收到“客户不可用”之类的自动消息或类似的回复，则可能意味着他们的手机已关闭或处于“请勿打扰(Disturb)”模式。
- SMS/MMS向此人发送消息。如果您发送文本但未显示“已读(Read)”或“已送达(Delivered)”通知，您将在文本下方看到除空白之外的任何内容。在 iMessage 中，已交付(Delivered)徽章将不再出现在您的消息下方。这可能意味着您已被阻止 - 尤其是在您发送消息已经过去几天的情况下。
- 发起电话会议(conference call)，看看您是否可以连接。
隐藏来电显示 (Hide Caller ID )
如果您不想使用不同的线路，您可以键入 *67，后跟此人的电话号码以隐藏您的号码。如果电话正常响铃不止几次，这几乎肯定意味着他们已经阻止了您未屏蔽的号码。
或者，您可以隐藏您的来电显示并呼叫阻止您号码的人。您的 iPhone 具有隐藏来电显示(Hidden Caller ID)功能，该功能可以隐藏您的号码，以便其他人的手机不会检测到它。
- 点按设置(Settings)>电话(Phone)。
- 接下来，点击显示我的来电显示(Show My Caller ID)。
- 切换显示我的来电显示(Show My Caller ID)选项将其关闭(off)。
尝试拨打阻止您号码的人，看看他们是否接听。
注意(Note)：如果该功能不起作用，您的运营商可能已禁用它，在这种情况下，您可以尝试从其他 iPhone 拨打电话。
通过聊天发送消息(Send a Message Via Chat)
如果您仍然无法与对方取得联系，您可以尝试通过WhatsApp 等 消息应用发送文本或聊天。(messaging apps)
检查您是否可以在WhatsApp上给他们打电话或发短信。如果他们没有接听您的电话，他们可能处于离线状态，或者他们已经阻止了您。
为确保他们在WhatsApp上阻止了您的号码，请发送一条短信，看看是否通过。如果您看到两个蓝色勾号或两个灰色勾号，则您仍然处于连接状态。如果只是一张持续几天的支票，则表明您可能已被阻止。
您也可以尝试将该人添加到WhatsApp群组，看看是否可以添加该人。如果您无法添加他们并且收到“无法添加联系人(Could Not Add Contact)”错误消息，则表示他们已阻止您。
检查语音信箱前的响铃次数(Check the Number of Rings Before Voicemail)
如果您在呼叫发送到语音信箱(voicemail)之前呼叫某人并听到通常的响铃次数，请不要担心 - 您仍然与他们保持联系。
有时您可能会听到不寻常的铃声。这可能意味着几件事：此人的电话已关闭，他们正在通话，或者他们已将所有呼叫重定向到语音信箱。
但是，如果您在呼叫被转移到语音信箱之前只听到一声响铃并且这种模式仍然存在，那么您可能已被阻止。
它可能是别的东西(It Could Be Something Else)
在大多数情况下，您的电话或短信无法通过可能有一个简单的原因。不要(Don)立即得出他们阻止了你的结论。也许他们遇到了网络挑战，或者他们没有按时支付账单。或者他们可能打开了飞行(Airplane)模式或请勿打扰(Disturb)。
在你下结论之前，最好给这个人一些时间。如果你经常见面，你可以问问他们。您也可以尝试通过家人或共同的朋友联系。
How To Tell If Someone Blocked Your Number on iPhone
You’re trying tо call someone, and your call doesn’t seem to be going through, оr they don’t seem to be picking up.
Worse still, you send messages to them, but you’re not sure if they receive the texts either — because there’s no response.
There are several possible reasons why that would happen:
If you suspect that the person has blocked your number, we’ll show you different things you can try on your iPhone to confirm whether it’s true.
How to Tell If Someone Blocked Your Number on iPhone
When someone blocks your number, they’ll no longer receive calls or text messages from you.
You won’t get any official alert or notification if they block your number. But, if you call and it rings once or doesn’t ring and goes right to voicemail, you may have been blocked.
There’s no simple process to tell if someone blocked you. However, you can try several different things to check if you’re blocked.
- Call from a different number and see if they pick up. If you don’t have enough airtime, find out how to use WiFi to make cellphone calls. If you call and get an automated message like “the customer is unavailable” or a similar response over several days, it could mean that their phone is off or on Do Not Disturb mode.
- Send the person a message via SMS/MMS. If you send a text and it doesn’t show the Read or Delivered notification, you’ll see anything but a blank space beneath your text. In iMessage, the Delivered badge would stop appearing beneath your message. This could mean that you’ve been blocked — especially if it’s been several days since you sent the message.
- Launch a conference call and see if you can connect.
Hide Caller ID
If you prefer not to use a different line, you can type *67 followed by the person’s phone number to mask your number. If the phone rings normally more than a few times, it almost definitely means they’ve blocked your unmasked number.
Alternatively, you can hide your caller ID and call the person who has blocked your number. Your iPhone has the Hidden Caller ID feature, which masks your number so that the other person’s phone won’t detect it.
- Tap Settings > Phone.
- Next, tap Show My Caller ID.
- Toggle the Show My Caller ID option to switch it off.
Try calling the person that has blocked your number and see if they pick up.
Note: If the feature doesn’t work, your carrier has probably disabled it, in which case you can try calling from a different iPhone.
Send a Message Via Chat
If you’re still unable to get through to the other person, you can try sending a text or chat via messaging apps like WhatsApp.
Check if you’re able to call or text them on WhatsApp. If they don’t pick up your call, they’re probably offline, or they’ve blocked you.
To be sure they’ve blocked your number on WhatsApp, send a text and see if it goes through. If you see two blue ticks or two grey checks, you’re still connected. If it’s only one check that lasts for several days, it’s a sign that you’ve probably been blocked.
You can also try adding the person to a WhatsApp group and see if you can add the person. If you can’t add them and you get the Could Not Add Contact error message, it means they’ve blocked you.
Check the Number of Rings Before Voicemail
If you call someone and hear the usual number of rings before your call is sent to voicemail, don’t worry – you’re still connected to them.
Sometimes you may hear an unusual ring pattern. This could mean several things: the person’s phone is off, they’re on another call, or they’ve redirected all their calls to voicemail.
However, if you only hear a single ring before your call is diverted to voicemail and the pattern persists, you’ve probably been blocked.
It Could Be Something Else
There may be a simple reason why your calls or text messages aren’t going through in most cases. Don’t immediately jump to the conclusion that they blocked you. Maybe they’re having network challenges or they didn’t pay their bill on time. Or they might have switched on Airplane mode or Do Not Disturb.
Before you jump to conclusions, it’s good to give the person some time. If you meet often, you could ask them about it. You can also try reaching out through a family member or mutual friend.
