How come my pictures aren't sending?

I have an iPhone 4s. The picture messaging was working fine up until last week, now my pictures won't go through. I tried sending a picture to my friend and the sending bar went up almost all the way then a red exclamation point popped up. I checked my settings, and turned off the MMS then back on and nothing happened. I also shut off my phone and then turned it back on but it still doesn't work.

I have the same problem with my LG Android phone.

  • Why aren't my texts sending? For the last couple of days my iphone hasn't been sending all the texts. The sending bar will get almost to the end and it'll stop. What is wrong with it?
