Windows Mobile 5 Smartphone as GPRS/Edge Modem

These are the steps to setup your smartphone to connect to lets say Cingular's WAP network with Dialup networking (DUN). This is also known as tethering.  I have the MediaNet unlimited plan and would recommend it for anyone doing this (don’t want a big cell phone bill).

I will use it via Bluetooth on my Windows Server 2k3 SP1 machine (should work on XP SP2 also)

Once you have your Bluetooth modem installed do the steps below

  1. Open the BT modem from the control panel of the PC (Control Panel -> Phone and Modem Options -> Modems Tab ->Properties button)
  2. Go to the Advanced tab and add (without quotes, case sensitive) "+CGDCONT=1,"IP","WAP.CINGULAR"
  3. Save and close that

you can create a new DUN connection

  1. Phone Number: *99#
  2. Username: WAP@CINGULARGPRS.COM (this is case sensitive)
  3. Password: CINGULAR1 (case Sensitive)

I got 115kb/s from my office.  Enjoy.  This was hacked together from data from a bunch of sites found using my Fav Search engine (will go nameless)

  1. In the Cingular store today the clerk there told me that Cingular would charge their data connect rates if they detected that the phone was being used in a tethered mode (this was at a store in Berkeley CA, the clerks seemed reasonably well informed though you never know).

    I may still experiment but just a cautionary note…. per KB rates could get pretty ugly….

    Very nice trick — I tried using some other configurations that use +cgdcont=1,"IP","ISP.CINGULAR" instead of +CGDCONT=1,"IP","WAP.CINGULAR".  The previous thingum didn’t work, but the WAP.CINGULAR does.  However, for login/pass I’m using ISPDA@CINGULARGPRS.COM and CINGULAR1 still… (and actually, I think they’re both lowercase).  Strange eh?  And, do you know, does this violate cingular TOS?

    Worked like a charm (Cingular 8125)

    Speed Test: 90/40Kbps

  4. Some people have been asking about how to tether (GPRS/Edge) with their Windows Mobile 5 SmartPhone via…
