S7 won't send pics via text over LTE, they immediately fail. Why?

    Problem started a couple weeks ago. My phone can no longer send mms picture messages over text when on the LTE network. When I manually switch to the "3G/4G" network in the settings it works fine, but on the "3G/4G/LTE" setting it immediately fails any pictures I send.

     

    No luck after multiple calls to tech support and the engineering team. All resets, etc were done by tech support with zero luck. I suspect the latest update to 7.0 screwed something up. Any resolution to this issue??  After 13 years with Tmo I may be headed to Verizon due to Tmo's downward spiral the last few years.
