sounds to me like a bad solder of the port to the phone's board.
Any time you wiggle and get some contact - it's usually a cracked solder
or, as I had once on my Mac II, a line one of the layers of the board had cracked -
and it needed the extra weight of having the card slots filled to put enough
downward pressure on it to clear up the problem.
I could literally put my fingertip on the right place, and push down, and the problem
would clear up. I ended up using a roll of dimes in just the right place.
You can imagine the motherboard costs back then, and the blood pressure that
was relieved when the roll of dimes fixed the problem. I just realized, I probably still
have that $5 in that machine right this moment -- which is more than the machine!!
