First, I'm an android rookie. I'm managing a softball team. I need to be able to send 40+ phones the same message at the same time (SMS is fine), but get individual replies (each player/parent's reply should come to me but not go to the whole team). I just switched from an iPhone 4 to a Galaxy S5. iPhone app "Group Text!" was perfect - I'm having trouble finding something comparable for the S5/android. Advice?
