can't configure Pantech UM175

I started this post under Network/Internet, but it was suggested to placed it here. I have a Verizon Pantech UM175 that is recognized by the system, but Yast will not configure. KPPP also has some interesting glitches with it. I was able to get it to work using NetworkManager, but it freezes NM for 30+ minutes after shutting down an internet session. I have to wait for the system to decide it wants to play again. Is there possibly a conflict or setting that is messed up? Any help is greatly appreciated.

Please see the following post.
