My iphone 5 won't send photos?

I recently got the iphone 5 for Christmas and I had a bad sim card when I got it so I had to go to the att store to replace it, I was able to send photos up until two days ago. Now it takes forever to send or doesn't even send at all. It does this everywhere I go so its not just my internet connection. How do I stop this?

Go to settings general reset and reset network settings problem solved happened to me on my iPhone 5

  • Why can't I send my photos from my iphone to my email? I tried to send multiple photos from my Iphone to my yahoo email. I clicked on email photo and then typed the email and the subject in the correct boxes and clicked send. I've tried doing this in the past and it did not work and I just tried it again about 20 minutes ago and I checked my email and did not get the photos. I checked my mail and my spam and they were not there. Is there any other way I can do this! Why isn't it working?
