Verizon Galaxy s6 won't send pics or group text on T-mobile

[brdemorin]

Brought over Galaxy s6 from Verizon to T-mobile. Put in the below APN settings. Everything works fine except can't send pics or send text in a group text. I can receive a pic and receive a text in group text but can't send. I've tried 3rd party messaging apps to no avail. Please help!

See the settings here. If that doesn't work, bring the phone into a TMobile store and ask them to set the APN for you. (A Verizon S6 should have the proper bands for TMobile.)
