Why won't group messaging work on Samsung Galaxy S7 Edge?

jw1578

    Hey guys, I recently purchased a Samsung Galaxy S7 Edge. It is an AT&T Unlocked phone, and for some reason the phone will not send group messages on the T-Mobile network -- anytime I try to send them, it sends as an individual message to each person in the group. The APN settings are what they should be, and I've done everything I can with the Group Message settings. Anyone have an idea of how I would fix this?
