MMS(non imessage) doesn't work for me. It appears the photos go out, but the recipient never gets them. This occurs on wifi or LTE only. I've reset network settings(I have the current carrier update) a couple of times to no avail and have updated and verified my APN settings are correct. Running out of patience here--3rd week with tmo and have had plenty of coverage issues and dropped calls.
In other words if you shut off the LTE, can you send the messages on 4G?
I've resolved the issue--few reboots and network setting resets and they finally started working. Unicorn dust.
