Without going into a lot of detail, the short answer is the N800 can't always set up the right options to connect to T-Mobile USA. Occasionally this is due to a phone needing some advanced settings, but most often it appears that T-Mobile USA is just inconsistent, most likely a result of Voicestream's (it's name before the Deutche Telekom acquisition) growth through acquiring dozens of other companies.

The easiest thing to check is the "Access point name" and "Dial-up number" in the connection properties. Try using *99***1# for the dial-up number and internet2.voicestream.com for your access point. If that doesn't work, change the access point to internet3.voicestream.com. Those are the settings I pulled from the SIM card of my Treo 680, and they work for me.

As one who is Brain F**ting, (AND just got both the phone AND the N800) can you provide a bit more info after the pairing?

This is completely impossible with prepaid yes? I use T-Mobile prepaid - I only use the phone about 20-50 mins a month, so that costs me <$5 a month. Getting a monthly plan plus an internet add-on would be much more money than it's worth to me. However, if they allowed internet on prepaid, I'd buy a capable phone and be all over it.

The USA seems to be oblivious to prepaid. T-Mobile seem to be the only ones who make it really worthwhile. Buy $100 of credit and you get 1000 minutes, with nothing more to pay for a year, and all credit after that refreshes the existing credit, and lasts a year, so I just pay another $10 annually and it keeps it going. I keep meeting people who pay $40/month with similar low usage to me, and they just don't seem to believe me that prepaid works, or they get hung up with "I have 50000 minutes a month available, which works out at $0.001/minute, and you're paying $0.10/min! Mine's better value!".

(My other phone is a hardware SIP phone using Gizmo w/local call-in number, and Skype, so between my wife and me, our combined total fixed and mobile telephony costs are about $210/year, including frequent hour-long international calls)

D,

I tried the second option. Found the cab and loaded it with a sync then ran it but still don't see the option to use DUN. I can see the CAB file on my dash and execute the file, but don't see anthing. Am I missing a step?

I just posted a quick howto on connecting an N800 to T-Mobile USA using a Bluetooth-enabled phone (in this case, my Treo 680):

HOWTO: Nokia N800 + Treo 680 + T-Mobile USA

These really should work for any phone you've successfully paired to that supports the Bluetooth DUN profile. Having said that, I know there was at least one report here in the ITT forums that mentioned they had to add special AT cmds in the Advanced settings (though that was an older Treo, I think).

I have a Nokia 6086 phone, 29.99 Service and T-Zones and can't pair with my 800, either thru Control Panel-Phone or Bluetooth. Can you explain your post and how I can do this?

my n800 tethers to my dash with no problems. you can access PAN profile via xterm as root

Got the phone and N800 to pair and yhe phone to connect to the net, but I can't go anywhere (yes I know I COULD go to h*ll) any ideas where to look for a fix?

I do see packets sent AND received on the N800's end.

I use my N800 with T-Mobile USA on a Nokia N80 phone. I use the $30/month internet plan with no problems at all. The pairing is painless and you can easily share files between the two devices. I have not tried it with tzones.

You do have to make sure you pick T-Mobile USA as the provider when you set up the connection.

I AM trying to use T-Zones.
