people with GPRS problems...

I am one of those users that is having trouble connecting to GPRS more than once and getting the "unknown reason" problem. Only a soft reset or turn on/off flight mode will fix it. Well I found out what is causing this, at least for my device. I am running Wisbar Advance on mine and is what causing the problem. Once I closed the app, I can connect/disconnect GPRS as I please. I made calls in between also and it still works...
The developer for Wisbar is working on this issue so hopefully he will get this fixed. In the meantime, I have turned off Wisbar..
Hope this is what causing u guys' devices also.

Great info! Just a heads up. I had this problem since I upgraded to the 1.06 ROM however I have never installed Wizbar Advance. The only thing that I could get to fix it was upgrading to the Norwegian 1.11 ROM version or using the 1.10 US Radio stack. Even the Finish 1.11 did not fix the problem.

I have the problem and I'm not using Wisbar. I guess magician_os1.11wwe_bigstorage_6.zip is based on the Finnish ROM?

You can add another application to the list of problem apps (at least this worked for me)
Sygic .mobile contacts seems to mess up GPRS as well.
I've been using the 1.06 WWE rom, and i tried anasky's 1.11 bigstorage rom, and both times, with .mobile contacts installed, i received the "cannot connect for an unknown reason" error, after uninstalling it, GPRS reconnects fine everytime.
Hope this helps some of you.

i changed my sim card to a new one and now i don't get that error. plus i believe that part of that error is the service provider.
hope that helps

I have Qtek 1.11 and same problem too
It is a real pain, I do not have Wisbar, and I can only connect once then need a reset. Any ideas out there?

One cheap solution is to put the phone in flight mode and then go back to reset the GPRS. Not very smooth, but at least better than having to soft reset.

I have tried to turn flight modem on/off but i still get the error
"dialed:isplnk1.swip.net. The answering modem has disconnected. To check your connection settings and change them if needed, tap settings"
Does ne1 know what I can do? so I can use my gprs again. it worked fine just a day ago, and I havent done anythin at all that could cause this problem

I don' t have a magician but a blue angel.
I've got the same problem.
It's the last built of IA Caller ID.
I've make a hard reset with no IA Caller and no problem again.

just double check the settings to make sure that the access point name shows up in the number section of the connection settings, when its not there that can cause the answering modem problems

I have 2 SIM Cards with the same number, one for the QTek 2020, and one for a Motorola mpx200.
If they are both switched on, then my GPRS is disconnected after about 15 minutes, and I can only reconnect by going in and out of flight mode.
If I switch the Motorola off, then I stay connected, and can disconnect
and reconnect properly.

Never had that error message. Only the one hamsup1o was talking about. Is the Norwegian 1.11 Ananskyfied yet? I want to test if the problem is fixed in that one.

For me, I don't think it's any one piece of software. Since I upgraded my Jam last weekend to 1.11, it continually disconnects from GPRS. Soft resets may or may not correct the problem on the first try so a second reset is in order. Trying to turn Flight Mode On/Off is a chore in itself. I may need to tap "Turn Flight Mode On" several times before it finally does it. Even when GPRS is connected it will only last 5 minutes. Then while still connected, going to a different webpage, says that webpage cannot be found. Very freakin' frustrating!! :evil:
So, today at work I backed everything to SD and did a Hard Reset. I then cancelled out of the Operator settings, but allowed the other apps to install and soft reset. I manually added my data settings and connected. Within two minutes I lost my connection. Reset the device and couldn't connect. Reset again and it's fine. It's hit or miss. Restored from backup. Gave a MS Voice Command error so deleted that. Several resets later on the train ride home and it's been fine ever since, for now!
The question is, could this be a T-Mobile problem? I called them yesterday and all they could tell me is that data outages in the Boston area may occur in the evenings due to upgrades. Perhaps it's just a coincidence that I did the ROM upgrade and TMo is acting up. I'm pulling hairs here!!

I have the exact same problem with my Jam on T-Mobile (in Colorado) however it seems to have gotten better with the 1.11 ROM. The strange thing is that it does not ever happen with my 6315 on T-Mobile. I have spoken with their customer services serveral times and we have tried a few different things. The last thing we tried was a brand new SIM card to remove that as a posible problem. Since doing that, I can stay connected to GPRS, take calls and it re-connects with out me doing anything and it seems to have helped.
I have not tried to see if there is any change between wap.voicestream.com or internet2.voicestream.com. Which are you using?

I have the same problem with GPRS and the Cannot connect for an unknown reason. It initially connects fine, but if I disconnect it manually, I cannot reconnect without the soft reset. I started getting this error when I upgraded to 1.11WWE last night. I went back to Version 1.06WWE and the problem was gone so it is defiantely a ROM problem. Imate's Customer "Dis"-Service continues to timeout everytime I go online with them. I am in the process of trying the UK 1.11JAM Rom to see if that makes any difference. I am with T-Mobile USA.
On the Club I-mate forum there are people with this problem as well and one of them is on Cingular!!! So it's not carrier specific.
__________edit
I tried the UK 1.11 ROM and it worked a bit better. There was even a new tab in the GPRS bubble that you could click to disconnect the GPRS rather than holding down the red phone button. But alas, I still got the Cannot Connect for an unknown reason mesage. I'm going back to 1.06 (Thankfully I backed it up) It worked fine. Is anyone having this problem with the Anansky hacked ROM?
Also, why does the UK version come with Skype and the WWE version doesn't?

Could it be due to Activesync?
I too have the GPRS problem, usually it occurs after synchronizing with the PC. The flight mode trick fixes it. I can repeat this behavior and can always fix it, so it remains a nuisance...
Since you can access the internet through Activesync, maybe the OS stays locked in that mode and does not allow for GPRS to be a valid network connection...
Anybody else have similar symptoms?

Mashie, I use internet3.voicestream.com. As you said nothing seems to help.
chinadan, Yes! I had the exact same thing happen to me last night. I've been tinkering with my Jam for the last week trying to get it to work. Last night it was working fine, but then I connected it to my desktop to load PHM Registry and when I disconnected, GPRS started flaking out! Performing a soft reset didn't help.
I've been going back and forth with i-Mate CS, and it's obvious they know there's an issue. They seem to be getting a little testie since I'm basically telling them I'm not an idiot so please get the crap fixed! They had the nerve to send me instructions on how to setup a GPRS Connection on the Jam! :twisted: What nerve!
Anyway, think I'll try loading the worldwide 1.11WWE and see what happens. Anyone have a backup of 1.06 US 850 ROM?
Thanks and cheers!

Well, I went almost 24 hours without a GPRS problem on my JAM yesterday. I didn't get the usual "Cannot connect for an unknown reason" error message. This time I got a message saying that there was a problem with the modem???? I don't know where that one came from... changed my gprs setting to internet2.voicestream.com and it works now....until the next error message.
Screw it. I'm going back to 1.06. The JAM is VERY sluggish now and I can't even get it into flight mode to correct the problem. I guess I'll wait for the patch. (It seemslike we spend most of our time waiting for a patch or an update of some kind. ARGGGHH!)
ALso, I don't know if this was the case with the 1.06 ROM, but I used to have to hold down the red phone button for a few seconds to get the GPRS to disconnect. But with the 1.11UK rom all it takes is for you to click the red phone button and the connection is dropped. Example: If I'm on the Today Screen with GPRS connected, click the red phone button and voila, gprs is disconnected. Is this normal? I don't remember it disconnecting so easily with 1.06.
Also, saw this over on the HoFo: ___________________

Any chance you give us a link to those pics? Pleaseeeeeeee :twisted:

Ok, been tinkering around this evening concerning the GPRS connection issues and this is what I have thus far. First, Club IMate has new Operator Settings on their website. One of their techs was kind enough to e-mail it to me this afternoon and checking their website this evening shows T-Mobile ver1.6. Applied those settings and it seemed to do a better job at installing my VPN settings for internet3.voicestream.com. However, when I checked the Connections screen it listed My Isp with my VPN connection and My Work Network was setup for wap.voicestream.com. Ok, nice but I don't use the wap settings. Connecting through IE to wap.yahoo.com resulted in the TMo Wap connection to launch, but not my VPN connection. So I went back into Connection settings and set both Work and Internet to "My ISP". Upon doing this and selecting any website from IE, it wouldn't connect and give me the error "Make sure you have your modem installed blah, blah, blah". If I then press and held on the "G" and tapped connect, it connected just fine.
So that got me thinking about the Registry again and why in the Connection screen for both Internet and Private network, why there was no option for "The Internet", or "My Secure WAP" so forth and so on. When I had my XDA IIs, those where options. So I loaded PHM Registry to the device and went exploring. The first thing I found and deleted was in: \HKLM\Software\HTC\WModem. I deleted the Preset GPRS key. The next thing I found where all the Interent settings I just mentioned in:
\HKLM\Software\Microsoft\ConnMgr\Destinations\. There is listed "The Interent" (which I tried to create myself in Connections but it said it already existed) and My Secure Wap plus others that I had made. So for starters I deleted "The Internet" key and reset the device.
Went back into Connections and created a new network called The Internet and added my connection to internet3. I then switched it to only look at The Internet network. Launching IE again and trying to go to wap.yahoo.com. Again, I get the "Unable to Connect: Ensure that your modems are presentand inserted correctly, and no network card present".
So obvioulsy, my edits to the Registry made little difference. So again that got me thinking. Why would their be a WAP connection when I selected T-Mobile VPN during the new cab installation? Because it needs it!
I then went back into the Network Management screen under connections and left it set to The Internet for programs that auto connect to the internet and set it to My Work Network for the private network option. Since doing this I've had no issues when any connection while browsing. If I go to a WAP site it automatically connects to T-Mobile WAP connection. If I then decide to go to a full blown HTTP website, it automatically stops the WAP connection and launches the VPN one. There is no delay when it does this, well, maybe a second! :lol:
My thinking is (and, I'm no programmer or Registry master!) that the problem lies in the Registry settings for IE. Perhaps it runs deeper than that but if one of you Guru's could take a look perhaps we can get this ironed out once and for all. Thanks for listening!

QTEK9100 and GPRS/EDGE - AAARGGHH!!!!

For some reason - my QTEK 9100 fails to maintain the connection to my GPRS service. Once I connect, it holds the connection until I make/receive a phone call. Thereafter, the device shows the connection in place, but it fails to pass any more data through the connection. To keep using the data connection, I must either soft reset or switch flight mode on/off.
(Needless to say, I have been able to use my SIM in other GPRS-enabled phones).
ROM 1.1.7.5
Date 9/22/05
Radio 01.01.10
Protocol 4.0.13.16
ExtRom 1.1.7.105
Anyone have any ideas?
Is there a ROM upgrade or RegEdit that could do the trick?

Same **** with mine 9100 on MTS. We should get together to solve this issue. Let me know if you got the solution. My ICQ 2662731, phone no. 916 137 7540, Leonid.

Absolutely the same problem with my Qtek 9100 on MTS. Some people on the forums say it's operator's problem; others claim it's not. However, switching from MTS is not an option for me anyway (corporate cell phone number, etc.) so I would be very much obliged for any solutions, or at least hints towards what can be causing it.
One possible solution (haven't tested myself yet) is setting GPRS to 'always on' via the registry editor; however
a) Will it drain my battery much more than usual?
b) Won't GPRS get disconnected in standby mode?

hi
hi. try to initiate GPRS connection with the default inbox email. press send and receive to check email. let it connect GPRS. when someone call u. it still maitain but the during call, the other person must pick up the phone. if nobody pick up the phone. the GPRS will have problem and need to turon and turnoff radio again. this is the only to maintain gprs, that is, to initiate GPRS connection with the default inbox email.

ad a) -
One thing I know for sure:
it will not drain your battery any more that when connecting gprs on demand. I used to use the "grps always on" feature and can't tell the difference in battery life.
Regardless of the "gprs always on" setting I do sometimes have problems with the connection. The icons (gprs) say it's on but no data is transferred (no e-mail/www received) but it happens very rarely and I can't tell in what circumstances.
By the way: holding the red off-hook key for 5 secs closes the gprs connection - check if it doesn't make your problem easier to bare ;-)
Maybe you could try another operator's SIM - at leat you'd know if it's the Wizard or the operator.

Yes, I know about this one; however, since GPRS won't reconnect anyway, this doesn't solve anything for me.
Oh well, I'll keep experimenting and hopefully Qtek will release some ROM updates in the future to deal with the problem.
Update: After playing with the settings a bit, the problem indeed seems to be with phone calls; i.e. I can disconnect/reconnect GPRS manually without any problems, but once a phone call is made or received, GPRS stops reconnecting. I have a suspicion it's actually an operator issue but haven't had time to try some other SIM yet.

I called service today about this problem, they heard nothing about it, they said. Also they invited to flash rom, that was released month ago, they said. I asked them about version but call operator didn't know.
I'm afraid to do that because they could flash older verison than I have, and there are some roms that have troubles with incoming calls, I read in russian Qtek forum.
My version:
OS: 1.3.9.4 RUS
Date: 9/29/05
Radio: 01.01.10
Protocol: 4.0.13.16
ExtROM: 1.1.7.105
I read there are some utilities to save rom but I cannot find how to save rom to hard disk to restore it in future surely.

My version is:
ROM 1.1.7.9
Date 9/16/05
Radio 01.04.10
Protocol 4.0.13.17
ExtRom 1.1.7.111
(Russian OS)
Just read on some Russian forums that there were the same problems with s100 until the new radio version was released, so I guess we just have to wait.

Just tried it myself, didn't work for me either.
So far, the problem can be diagnosed as: regardless of GPRS status, a phone call (outbound or received) will screw up the existing GPRS connection and any future attempts to reconnect unless a soft reset/flight mode switch is made.
I hope to god a ROM update will be available in the near future; meanwhile, any and all suggestions are welcome.

Today I visited service, they flashed me the same rom I already had. Then they tried to solve problem at least 2 hours but with no success.
I advised them to be ready for crowd of users of 9100 who connect to MTS.
Technician said I have to wait new rom update, but he cannot say nothing about release date.
I want to beleave...

Some guy at Russian forums put forth an idea that our problem might in fact be an issue with lousy MTS implementation of EDGE.
So in theory it could be solved by turning EDGE off entirely (if it is indeed possible).

Same problem on my Qtek 9100 ... is there any updates available for the ROM?

I have this same problem on both my Kjam and Qtek 9100. I am in the United States and use Cingular. I suspect this is not a carrier problem.

I'm in the US on Cingular with a Qtek 9100. I think the issue is that the carrier drops the GPRS connection after time, or the signal is lost and WM5 doesn't react. Either way, seems like leaving GPRS in constant ON mode plays into the problem rather than help it. After installing GB-SOFT Tweak http://msmobiles.com/news.php/4714.html and setting it to release GPRS if unused for more than 10 or 15 minutes, I don't get the GPRS problem nearly as often. Furthermore, when a GPRS lockup does occur, turning flight mode on and then off again restores function without the long cycle time of a soft reset
Christian

I had the same problem on my IMate and it was fixed by turning off (2sec) and then turning on your device once the GPRS connection was established. Haven't tested on my jam yet

I have the same problem since upgrading to AKU2 ROM - before I never had that issue...

Cannot connect, End current call and try again error

I have an Xda Exec with:
JasJar
ROM 1.30.76
Radio 1.11.00
ExtRom 1.30.164
I keep getting error messages connecting to T-Mobile USA I reset and it works for a little while but then it drops again. The phone function is acting up too, sometimes it tells me either call failed or no service where I know there is service, usually a reset fixes it but it is very unrelialble.

Yep happens to me too. I started a thread on this subject matter two months ago I think Here : http://forum.xda-developers.com/viewtopic.php?t=46646
The Jas Jar (HTC 3G phone) has to switch from phone to data, data to phone. Sometimes it does not know if the phone is finished. If you get heaps of calls then using a PPC may not be your thing. But if you need PPC for the other PC features then it works great. I dont get a lot of calls so others may rebut this.
Having a poor signal doesnt help, getting adapters and antennas is the challenge see other threads on this forum. Currently they ( any manufacture ) are just starting to make adapters available, however no forum users have posted any success stories yet.
With skschema (http://s-k-tools.com/) , I wrote a script that checks data conection every hour, if the connection fails I force a reconnect, if reconnect fails, I turn GSM off then back on, if that fails I reset and reconnect GSM and internet . This script is like "Stay connected" software out there. I also have other maintence scripts, email checking, etc.
I was knew to PPC this year, I took me 3 months to get sorted, but I am happy now !
GoodLuck

I don't agree with your obversation about a PPC not being good for lots of phone calls I have a Wizard that is stable and does almost everything.
For the money of these phones I would expect to have both. I cannot believe that it has such a hard time with the simple things.

Fair enough, I use mine for data, emails, and internet.
I dont distribute the phone number, I use device as a mini laptop.
You are correct, it should handle all the calls you get.
However the Jas Jar is one of the first phones out there with phone to data on 2G and 3G. So maybe the next or future device/Operating system of this functionality will be better at switching between the two infomation types.
I thought 3G was not yet in USA ?

We have 3G but it works on the 1900 spectrum which make this phone useless execpt for GPRS.
I bought it for the larger screen and the keyboard I like how you don't have to press the function key to imput numbers while typing.
If I can't get this to work I will have to go back to my Wizard.

Phone Not connecting to Network

Not sure if any of you guys here have faced this issue. But quiet often when I reboot my phone it starts up to the home screen and then doesn't connect to the wireless network, so basically i see the home screen and none of the buttons work, I remove the battery several times and suddenly it connects to the network.
Is this a known issue and is there a workaround?
I use the official windows mobile 6.1 rom released by HTC for the Sprint Mogul

I'm hearing two problems here:
1 - Your phone doesn't connect to the network. Have you tried to do a hard reset? That sounds like a software issue. Make sure you back up all of your cab files and contacts/mail/texts that you want to keep.
2 - Your buttons don't work. That sounds like a hardware issue and not necessarily related to the network issue. Have you brought it in to a Sprint store to see if they can repair or replace your phone?

i am also facing same problem, my mogul shows wifi on status but does not detects the wireless network, and after several on/off (through wifi on off hardware slider) it sometimes gets connected.
Please help

Its neither 1 or 2.
usually when you switch a sprint phone on you get a pop up saying "connecting to the sprint network dialing # 777" and after sometime, once the network connects then the phone is fully functional.
sometimes for my phone on rebooting it doesnt connect to the sprint network and as a result my phone remains unusable, in the sense the touch screen/buttons dont work. after several soft resets/battery removal it finally connects. I live in an area where there is good network connectivity!

OK, thanks. That gives me a much clearer picture. I don't think this is a network problem. You most likely have something on your phone that causes it to freeze during start-up. Did you install something new or make a registry change just prior to this starting? Also, would you be willing to either reflash or hard reset your phone? A new flash with a re-cooked or different ROM will most likely help you out.

which recooked rom would you suggest. I use the default windows 6.1 rom released by sprint. and btw I removed phone alarm from my phone and it starts up fine now.

There are a few great options, and it's personal preference.
Ryan has made some very good ROMs available here on the upgrade forum.
DCD's last public version are still widely popular.
TPLane37 has made some neat WM 6.5 ROMs available
There's also some good stuff going on over at ppcgeeks.com using the most recent build of WM 6.5
You can also try cooking your own ROM using the tools at ppckitchen.org
Make sure you read up on how to flash before you try it. The process involves a number of steps that must be completed in the proper order.

TD2 losing network reception - handset or network at fault?

Hi guys, I'm hoping one of you knowledgeable people might be able to help please, I've done a bit of seraching/googling but not really got anywhere...
I've noticed over the last few days that my TD2 keeps losing reception in places where I normally have a very good signal - e.g. the handset will be sat on my desk at work for a while, and when I pick it up to use it to make a call, send a text etc I notice that the network icon on the taskbar at the top is showing an exclamation mark to indicate there is no signal. I have to power off the handset and turn it back on to clear this problem (I've tried going to the comm manager and disabling/enabling 'phone' but when I disable it I cannot re-enable it afterwards).
I was wondering if this is a problem with my handset or the network (T-Mobile UK)?
Anyone got any ideas please?
Device information in case it's needed:
ROM Version: 1.39.405.2 (47382) WWE
ROM Date: 04/07/09
Radio Version: 3.43.25.19
Protocol Version: 61.20t.25.10U

I had the same problem in areas where the 3G signal is weak. I disabled 3G and everything is OK. I also noticed a dramatic increase in battery life.

the handset will be sat on my desk at work for a while, and when I pick it up to use it to make a call, send a text etc I notice that the network icon on the taskbar at the top is showing an exclamation mark to indicate there is no signal.

I get this every 2-3 weeks (known strong signal area, no reception at all indicated), it could a bug in the Radio ROM, perhaps? Updating the Radio ROM might help. But this...

..doesn't sound right. I do this and it clears the problem without restarting the phone.

@ kskar - Sometimes I'm in a good 3G area when this happens (Manchester city centre, UK) and sometimes I'm not (at home), so I don't think this would be causing it.
@ Pete_S - I was wondering if it could be anything to do with the Radio ROM... I also tried turning airplane mode on/off in comm manager, but it usually won't come out of airplane mode either without powering off & back on.

You could also try constraining the phone to operate only in the UK bands (phone settings - Band - GSM(900+1800) + UMTS(900+2100)) and, if you only use 3G, set network type to "WCDMA".
