Hi @Amardeep Sharma We are sorry to hear you're facing this issue. Did you make any recent changes to your C# app?

The “Unauthorized” error you’re seeing typically means there is an issue with the authentication or permissions. Here are a few things you could check:

Access Key: Ensure that the access key you’re using is correct and has the necessary permissions to send SMS messages. If you're using an API key for authentication, ensure that the API key is still valid and hasn't been revoked. If you're using a connection string, verify that it is correct and hasn't changed. It should include the necessary information for authentication.

Check Azure Communication Services Resource Access:

Ensure that your Azure Communication Services resource has the necessary permissions to send SMS messages. You might need to check and update the access policies or roles associated with your resource.

Phone Number: Make sure that the phone number you’re using to send SMS messages is registered with the phone number capability sms:PhoneNumberCapabilityType.Outbound

Best,

Hi @Grmacjon-MSFT

Thanks for reply ..

c# code seems fine.. i was using same code earlier and it was working fine. Even if i am trying to send sms using CLI after generating fresh Primary key, still i am getting same error.

For: sms:PhoneNumberCapabilityType.Outbound , where can i get full example for this. as on stackoverlow

var capabilities = new PhoneNumberCapabilities(sms:PhoneNumberCapabilityType.Outbound);

// ... register the phone number and use it in the following code:

SmsSendResult sendResult = smsClient.Send(

from: "<from-phone-number>",

to: "<to-phone-number>",

message: "Hello World via SMS"

);

Its not told where to bind or use this capabilities .

Pemissions are given for to numbers to send sms.

@Amardeep Sharma thanks for the update. Can you please share the CLI command you're using to send the SMS. In the meantime. We will check internally with the engineering team to see if this is a known issue and get back to you.

I am using following command in CLI..

az communication sms send --sender "+18552398XXX" --recipient "+12794992XXX" --message "Hello there!!" --connection-string "endpoint=https://lms.unitedstates.communication.azure.com/;accesskey=MYACESSKEY"

If you need real connection string, i can only send that on email id. cant disclose here.
