Iphone 4 straight talk can't get picture messages or send?

Only had straight talk for a little over 24 hours can't get or receive picture messages talked to straight talk and they said i had to research it because it wasn't their problem.could somebody please help. And my iphone is not jailbroke. Can get on the internet without Wi-Fi.

Added (1). They told me they wasn't updated enough to fixed it. I was on my own. And the only way i can fix it is by jail breaking my phone and i don't know how to do that.

You need to update to the latest IOS. If it doesn't work then it might have to do with you having an older phone. Many developers update their apps and then they may not work properly on older iPhones.

  • Straight Talk iPhone won't send Pics? I have a straight talk iphone, I put a sin card in it. I did change the APN settings. The problem is that I can only send pictures to iPhones. I CAN't send pictures to other phones. Like android, etc. If you had these problems and fixed them can you please tell me? I have iOS 6, and I changed my APN setting by downloading the file from unlockitz.
