My iPhone 4 won't send picture messages?

I was working ever sense I got it but today it doesn't finish sending and bared exclamation mark appears and says it failed sending. Why is it doing this? It worked before and I already checked my settings and everything is on.

You need to have 3G on, have you checked that?

Could be a problem with the internet from your carrier. Give it a reboot and try again. If its still not working then a call to your service provider would be best.

  • 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 isn't letting me send/receive picture messages? I don't know what generation it is but it's the one without the front camera only the back. And ever time I send a pic a little red exclamation mark comes out
