I am having this same issue. I was a Verizon customer and never had issues with group texts. Now after switching to t-mobile I am either not getting group text messages with android and/or galaxy users, getting them 2-3 days later, or the android/galaxy users are getting kicked off the message and it's being switched to iMessage. Please let me know if this problem gets fixed for you and how!
