I'm new to the Windows Mobile platform using GSM and I'm trying to understand the operation of GPRS connection. I have a PPC, HTC TyTn, and I use it to connect to the internet. Most of the time I get a good signal with the antenna and four or five bars next to it. I also get the E or G icon for the GPRS connection. Sometimes when I move into an area I get the antenna symbol with an "!" next to it and the "G" symbol. From my understanding the "!" means no service but I can still connect to the internet. My questions is, due you need phone voice service to get a GPRS connection.
Thanks
E
yes voice is the lowest common denominator
both gprs, edge, 3g, h use the same signals
and voice is the base
Thanks for your reply but I'm still confused. I understand gprs and voice use the same signal but my phone indicates "no service". I can't dial out or receive calls but I can connect to the gprs network and get on the internet. My understanding is "no service" means voice service or the phone could not register on the network. If this is true how can I get gprs service or connectivity .
2 reasons as i see it
1. i'm wrong
2 you are roaming on a network which for some reason only roam data

hey
i have a really strange net thingy going on
two things
1- sometimes i get a E on my kjam and the internet works so great and my connection shows EDGE instead of GPRS and i like it so much but when im home it doesnt do it how can i configure it be just EDGE never only GPRS?????
2- when im on net on my phone or on pc thru my wizard i cant get incoming calls wats da deal with that help plzzzzzzzzzzzzzzzzzzzzzz
thanx
1. No, EDGE connection is possible because of the equipments of your phone provider, but it may not possible for all towers to have EDGE support, so you may get EDGE only on specific locations.
2. Because GPRS data connection shares the same connection with voice connection, so if you are transferring GPRS data, incoming calls are not received (However it is still possible to receive phone calls if GPRS is connected but not active).
hmmm thats sad
so is there like a specific rom that can boost the gprs speed?
and how can i know which towers are which?
thanx
It just depends where you are. When I'm at home (poor reception) its usually gprs, but when I'm at uni its edge.
My Polaris regularly loses the connection to my cellular operator (Vodafone in the Netherlands).
It happens more than once a day and even in areas with good reception.
The display then shows "No Service" where normally the operator name is shown and the icon for signal strength shows an antenna with a cross.
This in itself wouldn't be such a problem, if the phone tries to find the operator after the connection is lost. But it doesn't. Once it is lost, it stays lost.
I have to disable the phone in the communication manager and enable it againt to force the Polaris to search for the operator network.
My previous phone (a Nokia) didn't experience this problem and was used with the same SIM.
Does anyone else experience this problem?
And more important: is there some kind of setting (registry key?) to force my phone to search for my operator?
I too have the same problem. This happens for EDGE connection also on my mobile. When ever i connect and disconnected the device to my laptop, the connection to my EDGE connection is disconnected. Even if i open a new internet address, it will say cannot connect to server. I need to soft reset the device to connect to internet. I am having T-mobile USA connection. Please help. It disturbs a lot.
A work colleague is using a sim free touch cruise on the vodafone network but vodafone don't have any support for this device (mind you neither does HTC ). We got the vodafone settings for billpay vodafone off the internet and input them and can now surf, download gmail etc over HSDPA (H icon shows) and then it automatically reverts to 3G when not in use.
The problem is that the icon for 3G/umts in use is always on (ie the small 3G over the signal strength) and when the bigger 3G icon is touched it shows how long connected to 3G and as the device is still connected it keeps counting time even though the application using 3G is shut down.
My questions are as follows:
In this state (big 3G icon showing and small 3G icon above signal strenght) is this costing anything being constantly connected to 3G but not using it?
How can it be set to automatically disconnect?
My own touch cruise is on the 3 network but I don't have this difficulty.
My thinking is that it might have something to do with "vodafone live" but not sure what is happening or possibly have selected the wrong set of settings for vodafone ireland as there is a few different sets.
Sorry this is a bit long winded but any advice much appreciated.
The always ON connection is general behaviour... it doesn't matter which network is the device on.
The big 3G/H icons only represent the available network (G(PRS)/E(DGE)/3G/H(SDPA))
The smaller is the signal strength...
The cost of the always ON connection depends on the dataplan being used... if it's an unlimited or a fairly large one like 5GB, it won't matter... but it realy depends on the data recieved....
In my case the avarage hourly traffic is around 1 MB, but i have a little e-mail traffic going so... whith a few mails and every 30 minute checking the traffic should be around 500 KB or lower...
As for the Auto-Disconnect, please search the forum... there are several threads about this in both subforums.
Thats great gnick666 thanks for your reply.
I know the Advanced Configuration Tool has an auto disconnect feature, but I had some issues with it and never went back to go play around with it.
You can also hold down the End button and a menu pops up and you can end data connection there. Or alternatively you can configure it so that holding down the End button always disconnects your data connection.
I have an unlimited data plan so not worried about data, I'm not sure however what the impact to battery usage is so I disconnect "just in case".
As for the 3G / H icon behaviors. Depending on which part of the country I'm in, I get different icons. Sometimes I get 3G and it switches to H when doing data. Othertimes it's always H whether disconnected or connected. (This is assuming that I'm in a 3G location) and not switching back to Edge.
Mine mostly shows the bigger 3G icon and the signal strenght icon with the little antenna icon (I'm on the 3 network which is 3g) but when I download data the small icon changes to 3G and then both change to H as required. Once finished it disconnects and reverts back to 3G. I have Schapps Advanced config tool installed.
Can anyone tell me how to do the simultaneous voice and data? I remember my Hermer used to let me do that. Any solution?
Don't know - it just does! However only a 3G network will support this, so make sure that you have the H or 3G symbol at the top. If you are on 2G, the data connection will terminate whilst on a call.
I think that some phones had two radios..one for voice and one for data..I'm guessing the TP doesn't have this
is there some way how to set the HTC PRO to the situation that the phone has priority from the EDGE?? something like that, when i am in data connection and there was call comming, that the data connection will close and i can take the call??
Now i am unreachable when data conncection
A 2G network is NOT capable of both telephony and data at the same time - it has nothing to do with the phone. As to what takes priority - i am not sure, but if you have an active data connection, i guess the network sees this as the phone being "engaged". THis is a limitation of the network and not the phone. I use my phone in 2G mode with the data connection always open - to allow email push. When i get a phonecall, the data is dropped by the network to enable the call. You need to ask your network provider.
3G can carry both data and telephony at the same time and doesnt need 2 radios. The touch pro supports this.
Hi,
My connection is HSDPA(the letter H is shown).
I was trying to access the internet while making a voice call. Sometimes it works, but most of the time the icon changes to G or E and go to suspended!!!
After the voice call ends, it goes back to H!!!
Is anyone having this issue?
That happens to me a lot when I'm in an area with almost no 3G signal. I get the 3G and H with one or two signal bars until a call comes in and it shows E and shows 3 or 4 signal bars. Haven't had these issues inside a major metro area with strong 3G signal.
