Twilio's test MMS (or any Twilio SMS) messages have never worked for me on the AT&T and Tmobile MVNO Straight Talk which uses Tracfone's MMS servers. I'd be curious what other MVNOs lurking about in the US are not handled by this. Does Cricket work?

Would love to learn more about why these messages are failing for you. Reckon you could shoot us some of the failed SmsSids to help@twilio.com? I'd be much obliged.

I'm not using the API only the "see for yourself" link on the MMS page at https://www.twilio.com/mms.

Webpage says it's sent but nothing ever arrives to the phone. I'll send an email to help@twilio.com with my phone number if someone over there wants to try a few test sends for debug info.

As a side note I just tested using the SMS page and it seems to work now. When I last tried it a couple months ago when swapping SIMs and trying to test SMS it silently failed with both sets of phone numbers and SIM Cards while every other SMS source I could try worked fine. That appears to not be an issue anymore so it's just MMS.

MMS to and from the phone works fine with Verizon and AT&T cellphones so I'd imagine there is some plumbing somewhere going wrong in my case.

Thanks.

Thanks for that - will definitely check it out.

I just tried this as well using my AT&T Straight Talk phone number, and the result was the same (message reports being sent, but never shows up on my end).

I'll also fire off an email so that you can have at least two numbers to test with.

Thank you!

That demo is still using our short code - we need to update that demo to use our new long code product. Thanks for the bug find!
