Can't send nor receive photos to/from non-iPhone users
I have Metro PCS and I have unlimited data and ever since I updated to iOS 8, I haven't been able to send picture messages to non-iPhone users. I have tried everything I've found online and nothing works. It was working PERFECTLY before we updated to iOS8! I could send picture messages to anyone without any problem. The rest of my family, who share the same family plan with me, can send pictures just fine (they're all android users). However, my sister and I, who are iPhone 5s users, can't send nor receive picture messages. Every time we try to send a pic to an android user, it immediately says not delivered. It doesn't even try to send it. And it's not a problem with my data because I can watch youtube videos with my 4g just fine. I even turn off the Wi-Fi to test it out and it works well. Does anyone know how I can fix this?
iPhone 5s, iOS 8
