I have no issue sending or receiving pictures from other people with my S4; however, when I send pictures, I'm regularly told by who I was trying to send it to that it wouldn't come through or wasn't attached. On my end it looks like it when through, though. Some of my AT&T friends receive a message saying the message was deleted. I have the issue with all carriers, including Verizon, and with mulitple different phones. I've checked the Global/LTE mobile data issue and this problem happens when I'm on WiFi and when I'm not. Happens at least half the time. Sometimes, they get it if I resend it, but many times it's a lost cause. Really frustrating...I didn't have this issue with an iPhone, but it's making me want to switch back.
