Hours and hours and hours wasted searching through so many different websites, when all I needed was what I'm about to type. I've seen recent posts in the dozens, on this site and about five others, with the same series of questions. Though there are plenty of answers, it is unfortunate that most people do not realize the specificity of what they're saying and lead many people into frustration.
This is some real, accurate information, for a only a specific case: Cingular Wireless, $20 Data Package, GPRS, Nokia 6820 with EDGE technology, Dell Axim X30.
I just achieved success with the following settings:
In the 6820 phone itself, change the GPRS access point to wap.cingular instead of isp.cingular.
In the PDA:
Number to dial: *99# (instaed of *9***N#)
Username:
WAP@CINGULARGPRS.COM
Password: CINGULAR1
In the Start/Settings/Connections/Connections tab, under "Bluetooth" and the "Manage existing connections"...enter no country code, and only your 3 digit area code. then, you must! enter, in the "advanced" portion, the following string:
+CGDCONT=1,"IP","WAP.CINGULAR"
Notice that the
WAP@CINGULARWGPRS.COM and the +CGDCONT=1,"IP","WAP.CINGULAR"
and wap.cingular in the phone ALL MATCH (as in all contain WAP). NONE of them, at least for the 6820, are isp.
Some things to remember: THIS IS NOT GOING TO BE THE CASE FOR EVERY PHONE/PDA COMBINATION, though most situations will greatly resemble this one. Let this sentence save you much grief.
Sometimes, the PDA will be just plain incompatible, and super-hesitant to even connect or maintain connected to the Phone. This was not my case, luckily. In that situation, seek driver and even more technical support.
There are basically two types of "numbers" you can dial. THIS depends on the PHONE. It varies even within the same manufacturer--completely bizzarre, I know, but it does. *99# works for the Nokia 6820 (its sitting there connected right in front of me) and also for the Nokia 6620, but I've read dozens of posts where other Nokia and Sony Ericsson users have used the number *99***N#, where N is the number 1, 2, or 3 (eg. *99***2#). You will have to play with these settings, experiment, and find the right matchup.
On top of that, the access point can differ also, from the posts that I've seen. Some people have success with isp.cingular, and others, like myself, must switch over to wap.cingular for it to work. But keep in mind that the +CGDCONT=1,"IP","WAP.CINGULAR"
string must match the access point. As in if you use isp.cingular, you must use +CGDCONT=1,"IP","ISP.CINGULAR"
(BTW, the quotation marks should be entered as I type them--I had some confusion when I saw others posting with another quotation mark before the + sign--there isn't one in the string). Likewise, if you use wap.cingular, you must use the string: +CGDCONT=1,"IP","WAP.CINGULAR"
That's about all that I can say. I've outlined my experiences in detail, and I hope they help the many people I've seen having trouble connecting the 6820 to the dell axim x30. I hope this helps some other people who have different setups as well, by helping them realize they are going to have to experiment with the different combinations possible here in the number dialed, wap.cingular versus isp.cingular, and the corresponding strings above.
BTW, all of this can be done WITHOUT paying 20 dollars for the BVRP GPRS Manager program (do a google search). However, if you find all this a bit too much to mess with, just by the program. There is a "GPRS Manager 2" out on the BVRP website that should have the settings for every modern phone out there. It might just fix your situation instantly. However, the one thing you might have to change is isp.cingular to wap.cingular on the phone, even after buying and installing GPRS Manager on your PDA.
Good Luck
Choices:
in the phone:
isp.cingular or wap.cingular
*99# or *9***N# (or other ones for Verizon,T-Mo)
+CGDCONT=1,"IP","WAP.CINGULAR" or +CGDCONT=1,"IP","ISP.CINGULAR"
