Need help with Sprint PCS Aircard and Mac OS X

[Madmike007]

I recently purchased a Sierra Wireless Aircard 550, which supports both 3G and voice. Unfortunately, Sprint doesn't offer tech support for 3G and Mac. So I'm own my own to figure out how to make it work. This can't be impossible!

1. The account is a PCS Vision account
2. Config using TCP/IP using PPP
3. Account UN/PW, dial up number is #777
3. using PCS Vison modem script

_G4 Ti 800
_OS X 10.2.6
_Sierra Aircard 550
_Sprint PCS Vision data plan
_-aircard was activated on a PC (Dell Latitude) and worked.

When I create a New Port Configuration, I only have the following to choose from; Interna Modem, Built-in-Ethernet and Airport. I leave Internal Modem checked and disable the others. From there I configure the modem with PCS Vision modem script and set ppp un/pw. Set the dialer to #777 and click connect.

On a good note: OSX does detect the Aircard 550 and the PCS Vision modem script has been installed.

This is the only thing I can think of thatcould be my problem. When I try and create a new port, I'm not given a choice of port for the sprint aricard. I just select internal modem and configure form there.

1. What exactly is the correct way to configure these cards?

2. Will I have to switch my account to voice and connect using SPrint PCS Phone modem script until 3G is viable on the Mac?

Thanks in advance.
