Amazon SNS for SMS won't send texts/fails to my mobile number


I am able to send text messages to other mobile numbers, but for some reason when I try to send to my phone, the SMS always fails.

There are no numbers listed for "Opted-out phone numbers (0)" shown in the console.

Our API code shows it was sent without issue:

Sent SMS messageId: c463103f-ec86-5671-aa81-4d074fa3219e; responseMetadata: AwsResponseMetadata(metadata=[AWS_REQUEST_ID, x-amzn-RequestId, Content-Length, Date, Content-Type]);

And it also fails if I try to "Publish Text Message" via the Console.

I can't see a way to note the failures in the console, it just shows counts of successes and failures.

  • Also, I am sending from the US to another US number and my phone is an iPhone.

  • Thank you. I have done this, and not it says:

    delivery.providerResponse Phone has blocked SMS

    How can I see where this phone number has blocked SMS? It is my phone number, but I don't know how to configure it to be usable for SMS. Perhaps I did a "STOP" reply to a text to show that users can opt out (they should always be able to do so), but since it's not listed anywhere I know, I can reactivate it.

    On the Amazon SNS page for "Text messaging (SMS)", the "Opted-out phone number (0)" shows "No numbers have been opted out."

  • FYI I ended up resolving this by sending the "unstop" to my SMS/Pinpoint phone number and that did restart it, though I'm not sure why it wasn't listed as an "opt out" phone number.
