When someone tries to send me a normal picture message from a standard phone, my phone always says "failed to download msg." I've received a "file to large to download" before too so I understand why those won't send. But I don't get why a normal sized picture fails to download. One time I asked my friend to resend the same one a minute later and it worked, but ever since then it hasn't. Is there a mode or something I can do to fix this?
