Cingular Windows Mobile 2125, 3125 or 8125 using as a PC modem
Unless stated, the following information does not represent the authors opinion or ideas, this information is presented as a composite for information freely available on the web sources that are provided where possible.
This article describes how to use the ModemLink feature on your Microsoft Windows Mobile 5 based phone over a Cingular's MediaNET Unlimited account, which at the time of this writing is an great value at $20-month for unlimited Internet usage over Cingular's EDGE (G2) network.
STEPS TO SETUP
These steps are required the first time you wish to use the SmartPhone
as a modem.
For Step 1: Connect to Internet
For Step 2: Set up my connection manually
For Step 3: Connect using a dial-up modem
For Step 4: Enter "Cingular" for ISP name (any name will actually work)
For Step 5: Enter *99# for the phone number
For Step 6: Enter WAP@CINGULARGPRS.COM for username and CINGULAR1 as the password
Once the wizard completes you'll need to Control Panel, open up "Phones and Modem Options", click on the "Modems" tab and select "HTC Modem" go Properties and then Advanced Properties. For "Extra Initialization Commands" past the following text.
You're all done with the setup.
TO CONNECT TO THE INTERNET USING YOUR SMARTPHONE
If you have problems connecting, try powering down the phone. Take the
battery out to reset it if you must. Once the phone restarts, put it to
Modem Link Active mode and try again.
Regarding if this process is authorized by Cingular, the answer is unclear but properly not relevant. In an e-mail exchange with someone who claimed to be a Microsoft mobile engineer (I have to say claimed because I can't verify, but he sounded knowledgable) I was told that the ModemLink software abstracts the data from the service provider, in other words Cingular can't tell (or more importantly, can't prove) when you're using a Windows Mobile 5 SmartPhone and ModemLink as a tethered device, as long as you log into their MediaNet server (WAP.CINGULAR).
ModemLink is an advertised and documented feature of the 8125, 2125, 3125, etc.. it's available on every Windows Mobile 5 SmartPhone solid in the US (source: Microsoft Windows Mobile 5 architecture and developers guide)
If you want faster connect speeds for you laptop or PDA, consider a laptop card and a subscription to Cingular's PDA data connect package. You'll pay considerably more, but you will have access to their ISP.CINGULAR gateway. WARNING: The Cingular 3125's Users Manual instructs you to use ISP.CINGULAR for your gateway when configuring modem link, this will likely result in "PDA Data Connect" plan rates or disconnect if you have not signed up for a PDA Data connect package.
Although it's not documented in the Users Manual, you can use the steps above to connect to the WAP.CINGULAR gateway using your 3125 without any problems. If you call Cingular support you may get conflicting information. I was told by a Cingular support rep that if you pay for MediaNET account you get access to Cingular's WAP gateway and that they do not audit what you do with the data you obtain through that network or how often you are accessing it, to quote the rep "you are paying for unlimited access... we do not audit your usage on the WAP gateway with MediaNET". Of course Cingular has their overpriced laptop PDA data connect service they want to try and push, so they aren't too open about how to "tether" over their WAP gateway.
How can you be certain all of this is true? Worried that Cingular will bill you extra or cut you off? Don't! All of the information in the post is a composite of data gathered from multiple sources. The origin of this material seems to be from this blog entry from an imfamous Microsoft Software Engineer Mike Poulson, that blog entry is still on-line.
I had an e-mail exchange with Mr. Poulson a few months ago and he confirmed that Cingular has taken no action against him or Microsoft for that blog entry (you have to consider, his blog appeared on a Microsoft sponsored blog, inadvertently his comments represent Microsoft, if this were a big deal there swords would have risen, but that didn't happen). Mr. Poulson also confirmed that he has never had any additional charges on his bill for data services.
I have personally been using this method for the past two months with no problems with billing. During my first month I even streamed video (as best one can stream video at 230-kbps) and left the connect going for over eight hours, Cingular did not disconnect or bill me beyond the $20 MediaNET Unlimited account.
Before engaging in WAP tethering using a SmartPhone, I sought out responses from this newsgroup and others. I looking for people with billing issues or service disconnect that could be unquestionably tied to WAP tethering over MediaNet, no one has reported this happening and if you search there web there isn't a single reported case.
All evidence seems to point to the way these devices have been designed, prevents Cingular from regulating their use in this way. So while the disclaimer is always "do at your own risk", know that this is sound and has been proven.
Make sure you've called to get the Media Net Unlimited. And not any of the other MediaNet packages. They have too many which are for text messages, or combinations of, or picture mail or what ever.
Just make sure you ask for the "unlimited internet" or if you don't have a cingular plan just get the: "SmartPhone Connect Unlimited w/Xpress Mail" which is just $19.99 /month.
To get you going the MediaNet Unlimited with just internet (no messages, or picture mail extras) is $14.99 so if you have trouble with the rep make sure to step him/her through the list and keep saying "NOPE" until they tell you a plan that's $14.99 and includes nothing but internet access.
Then hang up and follow the instructions that JDeats showed you here to get online.
JDeats' advice is excellent (and well written)
Just be careful that some things are in upper case and some in lower case.
According to the: http://www.gruups.com/cingular_internet page you have to have the APN of wap.cingular in lowercase (it shouldn't matter but I'm just following the page) and the username and password in upper case.
There's also instructions there about how to do it with bluetooth (it's super easy. As long as your cell already connects to the internet just fine it's just a matter of pairing it)
well i was wondering if there was any way of using the 3125 to dial in like a standard modem using the AOL dialing system. If so can you let me know in detail how it is done or link me to where i can find out how?
i am currently connecting through the USB cable supplied with the 3125
GPRS/EDGE and 3G work like broadband- Cingular itself is your provider- you can't "dial up" your own ISP on GPRS just like you can't dial-up your own ISP on DSL or a cable modem.
ok, so this means that i am not able to use my cingular 3125 as a "bridge" as it were and just use the call function of the phone itself to dial in like a standard 56k? i sort of understood ur response above but to me it seems like what i am trying to do is a functionality configuration question, not a service configuration question. I am trying to shy away from cingular internet service all together and just tap into my pool of minutes and use them to get internet on my PC.
In all honesty the way i see it is that if i can call a number on my phone and talk to someone on the other end, y can't i have my computer to do the same?
Please Let me know if there are some restrictions or minor details that i may be over looking. I know very little about cell phone to PC dialing but i have to say it doesn't seem to me like it should be a terribly hard thing to do.
The "modem" in the cell phone isn't really a modem in the traditional sense, but hardware/software that allows the phone to exchange data with the cell provider, who's really making the analog modem connection for you. This CSD connection between you and the carrier is the 9.6k bottleneck- the carrier's modem is capable of a faster 56k connection, but your phone connects to the carrier at a slower (9.6k) rate. CSD is "1G"- the original GSM data transfer method that has essentially been "replaced" by GPRS, EDGE, UMTS, etc.
For example, an eon ago when I was a Cingular TDMA customer, I had CSD on my account,and it worked at the relatively blinding speed of 14.4k (TDMA and CDMA use a faster implementation of CSD than GSM does- something about the larger bandwidth of TDMA and CDMA slots- I forget all the details.) Whenever I roamed on ATTWS, who didn't support CSD, the "modem" in my phone magically stopped working, even though I changed no settings on my phone. The only difference was Cingular accepted "data calls" and AT&T rejected them.
Even today, with T-Mobile, who supports CSD, I can make a dial-up call to an ISP, but I can't send a fax through my phone, because while T-Mo accepts data calls, they reject fax calls unless you add their $10/month "business CSD" service, which apparently lets you use their faxmodems in addition to their "regular" modems.
