Why can't I text photos from my iphone6 while using the LTE network?

When I text photos I get the red exclamation point and the 'not delivered' next to it.

Welcome to iMore! Go to Settings > Cellular, and make sure that "Enable LTE" is set to either Data or Voice & Data. You can also try going to Settings > General > Reset > Reset Networking Settings and checking to see if that fixes your issue.
