I posted a question about Killer Bees on another forum a couple years ago. A member told me to get ahold of John Smith at 205-239-6680. He's the guy that makes Killer Bees and the Sunray phones. Not sure if the number is still valid, but I did get in contact with him that way a couple years ago. Hope this helps.
Oh. The helpful member also told me to text him. Might have better luck that way.
