SMS send and receive sample

Shows how to use the SMS API (Windows.Devices.Sms)

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Specifically, this sample shows how to:

  • Send text message.
  • Set filter rules for registering with background infrastructure and then receiving the SMS based on filter rules.

Windows.Devices.Sms is a low-level API intended for use by mobile operators to push information to apps on devices by using SMS as the signaling channel. For example, a mobile operator may send a specially-formatted SMS message to signal the voicemail app that the number of unread messages has changed.

If you are interested in writing a chat app for sending and receiving messages that are visible to end users, then use the Windows.ApplicationModel.Chat namespace instead.


This sample accesses privileged APIs used by mobile broadband operators. Hence it requires the cellularMessaging capability, a special-use capability, to be declared in the package manifest.


  • This sample will not pass WACK because it uses a special-use capability.
  • This sample requires phone devices to be OEM developer unlocked.

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2017 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
