除了提供安全对话之外，Android 上的Signal 应用程序还可以用作 Android^(Android)上的^{(Signal app)}默认SMS^(Android)消息^(SMS)应用程序。使用Signal作为默认SMS应用程序的优势在于体验变得无缝。您可以通过短信^(SMS)和Signal应用程序同时与您的联系人聊天。这篇文章将指导您如何将Signal设置为^(Signal)Android上的默认 SMS^{(Default SMS)}应用程序。

^{(Make Signal)}将Signal 设为默认 SMS 消息应用程序^{(Default SMS Messaging App)}

1. 打开Signal App，然后点击您的个人资料
2. 接下来，点击 SSM 和 MMS
3. 点击启用短信选项。
4. 出现提示时，选择Signal应用程序作为默认SMS应用程序。

如果您使用，请启用短信^(SMS)发送报告和WiFi通话兼容模式。完成后，即使联系人不在Signal上，您也可以在^(Signal)Signal App中发送短信或从Signal消息切换到短信。它派上用场，因为当您没有数据时，对话仍然在同一个地方。

要将Signal作为默认设置删除并切换到另一个SMS/MMS应用程序，请点击 SMS Enabled 以选择另一个应用程序。

有趣的是，Signal 应用程序^{(Signal app)}不会读取任何以前收到的消息。它仅在成为默认SMS应用程序后读取收到的内容。对于许多希望Signal应用程序成为默认SMS应用程序的人来说，这将是一个劣势。

使用Signal App发送短信^(SMS)

将Signal设置为SMS应用程序后，它将同时显示Signal和非Signal联系人。要轻松识别Signal上有哪些联系人，哪些没有，请打开联系人并检查左上角是否有打开的锁定图标。这意味着如果您与该联系人聊天，它将不安全。此外，联系人将丢失视频和通话图标。

点击铅笔图标，然后选择联系人或按姓名搜索。如果联系人不在Signal上，您可以立即发送短信^(SMS)。如果联系人在Signal上，并且您想发送标准文本，请键入消息，然后点击发送按钮。

然后它将显示灰色发送图标和蓝色发送图标。如果您点击灰色图标，它将发送一条标准短信。您可以轻松识别SMS是标准文本消息还是信号消息。如果消息具有打开的锁定图标，则它是标准文本消息。

通过Signal App发送SMS/MMS不起作用？

如果您无法通过信号应用发送短信^(SMS)，那么您需要确保以下几点：

• 主动短信/彩信计划
• 连接到移动网络。
• 启用WiFi 通话^{(WiFi Calling)}兼容模式
• 发送短信的权限

我希望这篇文章很简单，现在您知道如何将Signal设为^(Signal)Android上的默认SMS消息应用程序了。除此之外，我们还解释了如何发送标准文本以及在安全文本和标准文本之间切换。

How to make Signal the Default SMS Messaging App on Android

Apart from offеring secure conversation, the Signal app on Android can also be used as the default SMS messaging app on Android. The advantage of using Signal as the default SMS app is that the experience becomes seamless. You can chat with your contact over SMS and through the Signal app simultaneously.  This post will guide you on how you can make Signal your Default SMS app on Android.

Make Signal the Default SMS Messaging App

1. Open Signal App, and tap on your profile
2. Next, tap on  SSM and MMS
3. Tap on the SMS Enabled option.
4. When prompted, select Signal app as the default SMS app.

If you use, enable SMS delivery reports and WiFi calling compatibility mode. Once done, even if the contact is not on Signal, you can send a text message or switch from Signal message to text message from within the Signal App. It comes in handy as the conversation remains at the same place when you do not have data.

To remove Signal as the default and switch to another SMS/MMS app, tap SMS Enabled to select another app.

Interesting to note that the Signal app doesn’t read any of the previously received messages. It only reads what is received after it becomes the default SMS app. That will be a disadvantage to many who want the Signal app to be the default SMS app.

Send a text SMS message using the Signal App

Once you have set up Signal as the SMS app, it will show both Signal and non-Signal contacts. To easily identify which contact is on Signal and those are not, open the contact and check if there is an open lock icon on the top left. It means the if you chat to that contact, it will not be secure. Also, the contact will be missing the video and call icon.

Tap on the pencil icon and then select a contact or search by name. If the contact is not on Signal, you can instantly send an SMS. If the contact is on Signal, and you want to send a standard text, type the message, and then tap on the send button.

It will then show a grey color send icon along with blue color send icon. If you tap on the grey color icon, it will send a standard text message. You can identify if the SMS was a standard text message or signal message easily. If the message has an open lock icon, then it’s a standard text message.

Sending SMS/MMS via Signal App not working?

If you are not able to send SMS through the signal app, then you need to make sure of the following:

• Active SMS/MMS plan
• Connection to the mobile network.
• Enable WiFi Calling compatibility mode
• Permission to send SMS

I hope the post was easy, and now you know how to make Signal your default SMS messaging app on Android. Along with this, we have also explained how you can send standard text and switch between secure and standard text.
