Verizon Galaxy S7

I've read all of the conversations on problems bringing an S7 from Verizon to TMobile. I did all of the various modification to the settings but still can't send/receive text images.

The modifications did enable me to access data on the network but that is it.

Does anyone out there have any other suggestions?

Right now my only two options are to go back to Verizon or buy another phone.  I really like the S7 as I prefer the smaller size and everything else works great.
