I'm hoping one of you resident phone expert brehs or brehettes might be able to help with this. Since I've been with Verizon for the last 2 yrs, I've had 2 Galaxy phones, the S5 and S6 Edge, was with Sprint prior. Was on the phone with a friend the other night, she sent me some pictures through text, I didn't get them until I got off the phone. I got a message that said "mobile data needs to be turned on" on the S6. I have wifi at home and phone is always connected to it there, the phone will bounce from 1x to 3G and 4G from time to time in the house. I use the Chomp messaging app, I would think pictures messaging would be able to use wifi while I'm on the phone, maybe I'm wrong.....
