I just switched from AT&T Wireless to T-Mobile, mainly because of the
unlimited GPRS for $19.99 a month. The only problem I had was that the
phone I got (Nokia 3650) is configured to go through
wap.voicestream.com, which gives me a private IP address that won’t work
with a VPN. So I did a little googling, came across this
thread, and did the following to make it all work:
- cd /Library/Modem\ Scripts
- copied “Nokia Infrared” to “Nokia3650″
- added the following line below
write:
"AT&FE0&C1S0=0\13"write "AT+CGDCONT=,,\34internet3.voicestream.com\34\13"
- configured the Network system preferences to use the bluetooth modem
with the Nokia3650 script, and used the PPP dial string *99# - crossed my fingers, made the connection, and was able to connect to
the VPN at work!
I figured this out while I was on hold with T-Mobile customer care; it
took me less than a half-hour of holding and talking to get escalated to
level 3 tech support. When the level 3 guy came on, I went over what
I had done, and he said that they sounded correct, although they’ve had
mixed results with the 3650 and Mac OS X. He also suggested I look at Ross Barkman’s Home Page, which
I’ve consulted in the past to good effect. All in all, the customer
care experience was excellent; most technology companies I’ve dealt with
try to avoid escalating whenever possible, but the T-Mobile folks kept
things moving and most important, listened to what I had to say.
