Here are the steps to set this up. I worked it out with their tech experts. this is not yet documented for the public.
- Visit Taniwha.org and scroll to "Scripts for Motorola GPRS phones." Download the file and put "Motorola GPRS CID1" in your scripts folder: /Library/Modem Scripts/
- Connect the phone to the computer via the USB cable
- Open System Preferences and click on Network. It should say that it detects the v188
- On the PPP tab, set the following:
- Service provider: tmobile (or whatever you want)
- Account Name: leave blank
- Password: leave blank
- Telephone number: internet2.voicestream.com
- Alternate number: leave blank
- (Advanced Options:) Uncheck ALL
- unchecked = send PPP echo packets
- unchecked = Use TCP header compression
- unchecked = Connect using a terminal window (command line)
- unchecked = Prompt for password after dialing
- unchecked = Use verbose logging
- On the Modem Tab:
- Modem: I had success with Motorola GPRS CID1.
- check = Enable error correction and compression in modem
- unchecked = Wait for dial tone before dialing.
