Azure SMS message is not received on phone after a successful response - node.js

Question

I'm using the latest Azure Communication SMS package, and basically directly copy/pasted the sample code to try sending a text to my cell. I got a successful 202 code back and can see the event successfully in the event grid I set up. But my phone never got the text, if it helps T-Mobile is my cell provider and I reside in the US with a US cell number.
Here is my code sample and response with sensitive information redacted
public sendSms = async (message: string, numbers: string[]) => {
if (this.checkIfReachLimit()) {
return;
}
const endpoint = `https://<resource name>.communication.azure.com`;
const credential = new AzureKeyCredential("<cred>");
const client = new SmsClient(endpoint, credential);
try {
const sendResults = await client.send(
{
from: "My Azure Toll Free #", // Your E.164 formatted phone number used to send SMS
to: numbers, // The list of E.164 formatted phone numbers to which message is being sent
message, // The message being sent
},
{
enableDeliveryReport: true,
tag: "workoutBuilder",
},
);
this.updateMonthlyCount(sendResults.length);
for (const sendResult of sendResults) {
if (sendResult.successful) {
console.log("Success: ", sendResult);
} else {
console.error("Something went wrong when trying to send this message: ", sendResult);
}
}
} catch (ex) {
// no op
}
};
Response:
{
to: 'my cell',
messageId: 'message id',
httpStatusCode: 202,
repeatabilityResult: 'accepted',
successful: true
}
