IPhone 5 won't send pictures to other phones?

I just got an iPhone 5 a few days ago for tmobile.It'll let me send pictures to people who also have an iPhone, but I can't receive or send pictures to anyone who doesn't have an iPhone. I've already tried resetting the network settings, but it still doesn't work. Anyone have any idea what can fix this?

Thats the iphone useless high security system.

You were should get Android

Please specify your problem properly is it a problem in mail, imessage or some app

IPhone can only share data with an iPhone or any other Apple product. You can't send/receive anything from any other device except Apple's. Same is with Windows Phones

Android phones don't accept pictures from iPhone due to how stupid Android is!
