  • Why won't my iPhone send picture messages? I have an iPhone 4 and every time I try to send pictures it gets to where the sent bar is almost full, then it just stops and won't send. What do I do? I've tried restarting my phone and it didn't do anything. It is on my plan though. I just sent a picture message yesterday but now it's f*cking up.
  • Why won't my iPhone 4s let me send picture messages? It gives me the option to send pictures and will let me choose a photo but when i press sent the little bar at the top fills half way then stops and a little red exclamation mark comes up next to the picture saying not delivered. Is there something wrong with the phone or can a change it my self in the settings?
  • Why can't I send picture messages with my iPhone to other phones? I can only send picture messages to other people with iPhones but not to anyone that has any other type of phone. I have the 4S and I have my MMS/SMS switch on. What's the problem?
  • My iPhone 5 won't send picture messages? I have had my iPhone 5 for a month now and only recently tried to send a picture to an android phone. However, when I try to send a picture message (MMS) it comes up undelivered. I have reset my iPhone and tried switching mms off and on. I also turned my phone off and on when I first noticed the problem. Does anybody know a solution? I'm on o2, so unsure if I need to set MMS up on there…
