I'm trying to write a program in VB.Net that establishes a GSM data connection from my XDAII to a Siemens M20T GSM modem.
I've been looking in the .Net documentation, and from what I've read it's unclear wheter I should better use Connection Manager (with the corresponding C++ code) or should call the Phone API :?:
Does anybody have any experience with gsm data calls?

Does anyone know if there is a way to connect to a normal ISP, using a GSM connection, instead of GPRS. I have data calls on my t-mobile account, but when i set up my isp details and dial it, the XDA tells me the remote computer is not responding, when it blatently is, cos i can dial it using my laptop.
Hi Dave,
If you are UK based T-Mobile have released their GPRS service last week. They have a number of packages including 0.075p per KB or £15 for 10MB.
Its not on their website but their staff know about it.

Your settings are wrong. Put the correct settings in. Ask someone who knows what the correct settings are in order to discover the correct settings
Maybe it's not all about wrong settings.
After I tried to connect to O2 using GSM from Danmark last week, I called O2 Germany and they told me it won't work. They have no roaming partner for GPRS in some countries and they disabled the GSM for whatever reason. The old numbers I could use to dial in last year won't work any longer. I get timeout error messages or "The connection you dialed does not answer". (It doesn't say it don't exist!)
Considering to quit O2 and use T-D1 again instead. I am very disappointed by the O2 net coverage.

OK, some networks do not support GSM data, and frequently networks will not have GPRS agreements with other networks in other countries.
Can you register onto Telia? In Denmark I believe they have GSM data @ 9.6kbps
You also need to make sure that your home network enables 'full' GSM data, maybe that's what you meant in your post. If they switched it off ask them ever so politely if they'll turn it back on.
I connect to the net using the wap number which is included in o2 minutes on the 250 package, (the gsm internet number was not included minutes) you can change the number dialled in the connection settings box. also set it to "always dial"
check the number dialled as it puts a prefix depending on country settings etc you also need data enable on your sim which is done thru your gsm provider. Sorry if i'm saying the obvious... hope this is of help
Dave, you need to have T-Mobile enable CSD (Circuit Switched Data), which is off by default. There is no charge to have this enabled.
Can someone tell if ROM versions RUU3.16.52 and RSU3.23.01 finally support GPRS Class B, thus if incoming (or outgoing?) voice call will NOT disconnect current GPRS connection?
TIA.
I downloaded the T-Mobile (NL) application for PPC2002 ("T-Mobile GPRS Connect") which should take care of the GPRS connections, but it does not work. It keeps complaining about not able to open the modem connection (I'm using the Cellular Line modem): "Can not find the name of the serial port".
Anybody any ideas?
It is a nice utility which displays the speed, send/received bytes and connection time, but useless sofar...

hey marco,
i bought a t-mobile pocket pc in the US and unlocked it. With my vodafone sim i now can do everythinh with the device. So I know how to make a GPRS connection to Vodafone, but don't know the settings for t-mobile.
A few days ago I also tried to install t-mobile app. but it sucks. I suggest you try to find out the correct settings with t-mobile nl to make a descent GPRS setting and not use the t-mobile application

Hi
I bought the first imate jasjam I put my hands on last week; I had read all the reviews I could find and I "thought I did all the research before paying $1100". Well I guess I missed one thing: mtctouch (Lebanon Operator) declared the device "incompatible with their GPRS server" and they are not planning any upgrade for the moment; still no reply from i-mate on the matter.
Am I the only one with a device too advance for the telcom op.?
Can I upgrade or patch the radio stack to become "backward compatible"?
I am running" JASJAM_Arabic_1.20.305.3_1.20.304.104_1.07.03.10
Cheers
for time being use setting phone and under band insted of auto for network select GSM and for GSM/UMTS select GSM 900+1800+UTMS 2100 (first select) or other for your country.
Hi Ridaz,
There should be no reason why this device doesn't work on their GPRS netowkr unless they use a portal system which checks the model of the device connecting to 'taylor' the content to the device.
Tell me do mtctouch offer a internet only GPRS APN or only a GPRS WAP one? Hope you know what I mean bu the term APN. The TyTn in effect should be setup to use the internet one and the mtctouch GPRS network would just see it as a laptop PC.

Hi
All 3G phones owners will have to wait until MTC finish upgrading their "equipment", hopefully mid December
Cheers
If there is anyone who owns a dopod 838 I need help. I need to know if GSMbeam works when you are using an ordinary gsm sim in your dopod. I don't care if the dopod is doing the sending or receiving, just that you are on a normal gsm network. I can't test myself because since I bough my 838, I transfered my number. Until I buy a new prepaid gsm sim I am stuck.
Give us a call.
SecureGSM see my pm. You must have encounted this problem. I have called three and tried to varify if they support umts csd but I am less than confident the modem support tech guy even knows what I am talking about. He said it is not supported but only after I sloooooowly explained what it is. The thing that bothers me is that my remaining gsm sim gives unreachable from the dopod in the same time as the 3g one. It should take a bit longer. I think the dopod is not realy doing anything when I use LINEMEDIAMODE_DATAMODEM. I have tried to use a plian LINEMEDIAMODE_INTERACTIVEVOICE call and that dose get through, I then do lineSetMediaMode(hCall,LINEMEDIAMODE_DATAMODEM) with both ends before using the call but it makes no difference as it is not supported.
Without LINEMEDIAMODE_DATAMODEM no negotiation takes place and even though on the sending side write attempts return success it dose not work.
CSD is not supported by carriers on 3G networks.
Please see for details:

Thanks for that cab, impressive. It is much better seeing the manual band options! The problem may well be with the 3g provider but I suspect that my regular gsm functionality is also not working on my dopod. In a few hours I will have another gsm sim and I will use the manual settings with that sim to test.
Using the cab from SecureGSM it is now possible to configure my dopod to work correctly with GSMbeam. I did vodafone to vodafone and it was smooth. I was also able to configure my 3g provider to put me into roaming mode using gsm bands but unfortunately no data call (csd) would go through. The bands tab did however disapear after resetting a few times and the cab needed to be reapplied.
next step- find how to use dual sim, setup call forwarding from my 3g number to my gsm number.
Thanks again SecureGSM!
