Hey! Thanks much for all of your suggestions. However, I need to tell you that I was the one that phoqued it up!
It was my wife's phone - SGH-T769.
Like I had said in a previous post, I was getting a 'network unlock code' - sigh.
I followed the exact procedure - to the letter - double, and triple checked my work . Still getting a 'enter network unlock code'
She came home Sunday afternoon, I was still fiddling around with it. She looked at me and said ".....do you think maybe it's a bad SIM card..? I'm not technical, but you've tried it on two phones of the same make/model..."
I looked at her like "...holy ****e..." - I looked closely at what I was doing. Guess what?
When you purchase the Straight Talk kit, there are 4 SIM cards in there - two micro/nano SIMs and two standard sized ones. The one that worked for my SGH-T769 was the orange SIM card - I was trying to use the gray one with hers.
This, my fellow Nerds, is what is known as an Epic Failure on my part - one for the Wall Of Shame for me. My wife has a degree in Criminal Justice and I have a degree in Comp Sci and Mech Eng. I guess skoolin' can mean absolutely nothing sometimes!
Problem solved - thanks to my wife - I think I'm gonna keep her around. Girls don't have the killer instinct and perverted mind that us guys do, so their brains can function a little more clear than ours can.
The frustrating thing - she is right 9.5 times out of 10. I just have to accept in lots of aspects that she is smarter than I am.
Thanks Bugs - Love ya!
