Source code | Package (NuGet) | Product documentation

Getting started

Install the package

Install the Azure Communication SMS client library for .NET with NuGet:

dotnet add package Azure.Communication.Sms


You need an Azure subscription and a Communication Service Resource to use this package.

To create a new Communication Service, you can use the Azure Portal, the Azure PowerShell, or the .NET management client library.

Key concepts

SmsClient provides the functionality to send messages between phone numbers.

Using statements

using System;
using Azure.Communication.Sms;

Authenticate the client

SMS clients can be authenticated using the connection string acquired from an Azure Communication Resource in the Azure Portal.

var connectionString = "<connection_string>"; // Find your Communication Services resource in the Azure portal
SmsClient client = new SmsClient(connectionString);

Alternatively, SMS clients can also be authenticated using a valid token credential. With this option, AZURE_CLIENT_SECRET, AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables need to be set up for authentication.

string endpoint = "<endpoint_url>";
TokenCredential tokenCredential = new DefaultAzureCredential();
SmsClient client = new SmsClient(new Uri(endpoint), tokenCredential);


Send a 1:1 SMS Message

To send a SMS message, call the Send or SendAsync function from the SmsClient.

SmsSendResult sendResult = await smsClient.SendAsync(
    from: "<from-phone-number>", // Your E.164 formatted from phone number used to send SMS
    to: "<to-phone-number>", // E.164 formatted recipient phone number
    message: "Hi");
Console.WriteLine($"Sms id: {sendResult.MessageId}");

Send a 1:N SMS Message

To send a SMS message to a list of recipients, call the Send or SendAsync function from the SmsClient with a list of recipient's phone numbers. You may also add pass in an options object to specify whether the delivery report should be enabled and set custom tags.

var response = await smsClient.SendAsync(
    from: "<from-phone-number>", // Your E.164 formatted from phone number used to send SMS
    to: new string[] { "<to-phone-number-1>", "<to-phone-number-2>" }, // E.164 formatted recipient phone numbers
    message: "Weekly Promotion!",
    options: new SmsSendOptions(enableDeliveryReport: true) // OPTIONAL
        Tag = "marketing", // custom tags
        DeliveryReportTimeoutInSeconds = 90
foreach (SmsSendResult result in response.Value)
    Console.WriteLine($"Sms id: {result.MessageId}");
    Console.WriteLine($"Send Result Successful: {result.Successful}");


SMS operations will throw an exception if the request to the server fails. Exceptions will not be thrown if the error is caused by an individual message, only if something fails with the overall request. Please use the Successful flag to validate each individual result to verify if the message was sent.

    var response = await smsClient.SendAsync(
        from: "<from-phone-number>" // Your E.164 formatted phone number used to send SMS
        to: new string [] {"<to-phone-number-1>", "<to-phone-number-2>"}, // E.164 formatted recipient phone number
        message: "Weekly Promotion!",
        options: new SmsSendOptions(enableDeliveryReport: true) // OPTIONAL
            Tag = "marketing", // custom tags
    foreach (SmsSendResult result in response.Value)
        if (result.Successful)
            Console.WriteLine($"Successfully sent this message: {result.MessageId} to {result.To}.");
            Console.WriteLine($"Something went wrong when trying to send this message {result.MessageId} to {result.To}.");
            Console.WriteLine($"Status code {result.HttpStatusCode} and error message {result.ErrorMessage}.");
catch (RequestFailedException ex)
