Quite often these days I am getting the issue mentioned above. Even soft resets do not seem to help. Until I reset a few more times.
What might be the cause of this? Thanks.
Hope someone might be able to assist on this. Thanks.
I'm also getting this message nearly every time I try to make a call. The phone then looks like it resets the connection with the cell tower and it successfully completes the call on the second try. Then the next time I try to call someone else it fails again. I came to this forum to see if anyone else has experienced the same problem.
Hey joej, I found out what might be causing the problem: make sure that your ActiveSync is closed before you try making a call. That fixed the problem for me.
Also, here's a quote from an email from one of my coworkers:
"Your Tytn was probably trying to dial a data connection at the same time that you were trying to dial voice and so it has to cancel the data request before you can dial out. There is a registry tweak you can do to the Tytn to keep the data connection always active when the phone is not in use and this may make it less frequent that you would have a problem
Activesync is supposed to stop when your data connection is unavailable. If you are making or receiving a call on the TyTN (or any GSM phone) your data connection will not be available and therefore not run. Do you have a lot of 3rd party apps running at startup as well? I have rarely had a problem with my Tytn and never during a call unless my battery dies on my BT headset mid call and then the device may get confused."
Hope this helps!

thanks for the update, i however am experiencing this issue once in a while and it is not with the activesync running nor a data connection going on. ugh..... guess mine is odd
Me too
Thank so much for the post count me in there too. I am southern central PA and just last week this started happening to me too. I have an 8525.
I have no acrive data connection nor any apps running that force a data connection. Every morning I have been resetting the phone 5-6 times before the freezing stops and it works. So annoying.
I am suspecting it is a network issue with cingular and them upgrading to 3g in my area. I suspect it as I had to travel north this week and discovered 3g coverage in Harrisburg so I am betting that is it.
I feel your pain and I have no fool proof thing to do on the phone to fix it. But man the phone on the 3g is fantastic.

yup, everything rocks in it except the phone functionality really needs to be improved to be more usable.
do you know how i can use the phonepad to do t9 for replying SMS ? right now i am finding it hard to do so as i need to use the normal input methods which is not as easy as a normal cellphone
omg I'm from Singapore using Starhub think I'm having the same problem too. Dopod 838 pro.
A soft reset works for me, but very frustrating coz you dunno whether you are missing calls - the screen shows mobile is up with signal and all but people can't call in.
Just started happening to me past few days but then again I just took over the phone from a friend who bought it 3 months ago (latest batch)
So frustrating. ... seems related to the activesync.. but then again still happens when activesync's not involved.

Same here anytime Cingy plays with towers, have you ever got a message stating the call can not be completed at this time? Been getting that one lately as well.
I think that it could be an issue with the phone heightened by the nature of the cell network.
I am wondering if the phone has issues handing off between cell towers as I have the band tab active and there are freq choices so I wonder if the phone even on gsm has some issues dealing with hand offs.
I locked it on gsm and still had issues with the phone. I locked it on 850 and still had phone issues. Put it in auto for the freq and still had issues.
On the U network on Cingular since its the only one the phone is excellent. Data and voice work great. So it will get better in the US for us on Cingular. But man its going to be really annoying during the roll out.
I'm on T-Mobile and I'm seeing this problem as well. (It didn't go away after closing ActiveSync like I said it did earlier.) The weird thing is that this wasn't a problem until about a week or two ago; now all of the sudden it's happening constantly.
Also, I just installed the newest HTC ROM (1.35.255.2) yesterday and now my phone has started to drop calls. I've never had a problem with dropped calls in the 2.5 years I've lived in this apartment.
Ain't technology grand?
Well things have not improved for me. Today after 8 resets the phone finally settled down and did not freeze and was able to get on the network. It has been terrible for me the last 2 weeks...
I removed the eten dialer skin I was using. I wanted to make sure it was not due to replacing the Cingular phone skin.
We shall see tomorrow if the phone is able to work without multiple resets..
If not it is off to a hard reset and re-load to see if that improves it any...
I have taken the plunge and did a hard reset plus reinstall of everything. I had the same apps installed again and the problem seems to be gone now. *touch wood* hopefully this doesn't come again... a restore takes too long. I have also installed Sprite and did a full backup of the phone including the memory card just to be safe.
This problem started for me this morning. (NYC/NJ Area - USA). I did a hard reset (actually, two) this morning, and it didn't fix it, even when the phone first finished the initial load (in a virgin state). Then, around 11:00am, it began to work again. Now, it's about 6:30pm, and I need the phone to call home to tell them I'm gonna be late, and it's out again. Seems like it's something not to do with the phone, but with the network (I hope). It won't connect in GSM, UMTS, or AUTO modes, FWIW.
Oh well, sure hope it doesn't takle two weeks to "go away".
returned
Well I returned mine. Did the warrenty exchange. So far so good. No freezing and the phone seems to hold onto the network ok now.
I truly believe mine was defective. As the phone would show searching and not connect to the network.
I think that not being able to make a data connection is a network issue as it clears up in a few days.

also in the same area, experiencing similar problems within certain specific locations. Noteably these are locations that I get SPOTTY UMTS service, so I assume a tower upgrade is in progress or something that is causing this. Where I have full umts service, the problem does not occur.
at times i have signal, but calls don't come through (rings to calling party, but goes to voicemail before my device rings).
This is something related to 3G because when the sim is put in a blackberry 8700c, everything works A-OK.
Glad to know i am not alone in this
I have similar problems. Especially in the university of Hannover. There is UMTS. Since a few days Data Connections via Active Sync don't work.
Before I had problems with calls. For example freezing during call.
And of course in the university and on other places I have often to do calls twice.
I called O2 for that problem. They are upgrading the cell around the university to HSDPA.
Hi to all !
I had the same problems, then i removed the microSD card and the problem was gone. Now i am testing the phone without miroSD card. I forgot to say that i had the problems with boot too(No GSM) and now it boot perfectly.
Best regards
O2 XDA Trion (dopod rom)
I finally had to return the phone under warrenty. It degraded to no gsm all the time fresh from a hard reset with no mem card. The new device has been flawless radio wise for a week now.
Problems with XDA Trion SOLVED !!!
Hi again !
The microSD card was NOT the problem ! I tested the phone without SD card but that was not the problem. Then i go to my provider and change the SIM card with new one (the old one was very old so i buy new one) and wauuu it works. The XDA TRION needs the sim card with UMTS suport then it will work fine. So far NO freezing at all. I will let you know in a few days if something strange will hapen.
Best regards
Hi, to all with the problem “The operation failed” when trying to make a call:
Try to switch off bluetooth (specially if you are in UMTS (CMDA) network) and then try to make a phonecall again.
For me this helped to solve it.
First I also thought that it’s only a Provider network problem (I have 2 different providers, with one it works, with the other I have the “operation failed” problems).
So it is 100% a phone software problem. (Shame to HTC)
Give feedback if it helped you too.
Hi,
Not sure if it’s my handset or for everyone in general in the UK on T-Mobile network.
Strange but true. While traveling, internet just doesn't work on my G2. Whether on the popular motorways such as M1, M25 or on train where T-Mobile coverage is very good, I get one or two bars the internet just doesn't work. It throws up error messages that it cannot reach the host it’s trying to connect meaning no data connection. It’s definitely not the coverage problem. Something to do with the phone as I never had this problem on my Nokia E71.
I called T-Mobile helpdesk but they just don't know and don't understand. Is anyone having the same internet problem while traveling? Any workarounds? I don't want to change the firmware as I can get a replacement from T-Mobile (I suppose) if I'm persistent with them. If I change the firmware, it may void the warranty as my phone seems to be faulty.
Any recommendations or workarounds?
Thanks in advance.
Hari
I'm getting something similar some of the time. I'm waiting for the official SW update in the hope that this will be fixed.
Yes, same problem here sometimes. I wonder if it's got something to do with the phone maybe?
Do you mean WiFi or 3g? One of the best things for me was sitting on eurostar watching the gps marker shoot across the screen as the map also was updating... that was a month ago, though, couple of days after I got the phone.
So do you ever get a connection.
When travelling in a car mine seems mostly ok.
It does lose internet connection sometimes when moving from a 2g to 3g signal and can take a couple of minutes to come back.
You could try forcing a 2g connection only to test if that works ?
Hi!
I have the handset for few weeks and for couple of days I have a problem at the times to connect to internet. Look like Hero try to send data but there is problem with downlink. Some times when you turn off and on the internet it seemsd to be working at the times ....
I have already updated the software to the newest from T-mobile but still the same problem.
Any ideas ???
Thx
Well i have the same problem with Telus in Canada I thought it was a network problem but now you have me wondering if it is a defect.
same here on T-mobile UK in London... I noticed a reboot solves the problem most of the times... But I am not too sure why it happens in the first place. I noticed it seems to happen in very crowded locations rather than when I am somewhere with not too many people. Every time I install a new radio I hope to see the problem disappear, but it never really does. Quite disappointing... :-( Hope for a fix in the near future though.
I've been getting the same problem.
The HSDPA icon will change to 3G, then the connection will stall completely. I'll have to put the phone into airplane mode and back again to restore it.
T-Mobile tried fobbing me off with my contract didn't allow high speed data, to the next person telling me to just try it in a different post code, they're not aware of any problems, with finally the most recent tech support person telling me T-mobile is aware of a HSDPA and 3G problem that should be fixed in 5 days, please bare with us.
W*nkers.
I definately feel like I've bought a red herring with this phone. Or should have at least got it straight from HTC. I'm reluctant to put a new ROM on there so soon after getting it.
In Canada it seems like it is a network problem. I went out of town about a hour and data worked, came back and it did not work. Phoned and was told it is a network issue and to bear with it they are fixing the problem in a couple days. It seems odd that the same thing is happening in two different across the ocean at the same time though. Who knows if it is the same problem though.
I have the same issue with Orange till this weekend when the phone won't work on 3G at home at all even though it gets a signal. The 3G netwrk is down in my home cell area for a week so I'm stuck on 2G. 2G speeds on some sites are even better than 3G as it doesn't stall on the downlink.
I had this issue but it seems to be OK now. Probably a network issue.
Hi !
It look like the blame is the simcard
Someone suggest something and it give me idea. I have put bit of paper betwen simcard and the thing that hold it and then just a bit on top of it and does seem to have problem. It look like Hero have very sensitive simcard holder
Good luck
All fine here!
I'm in south London, UK and never seem to have a problem with the internet. I'm extremly impressed as on my bus journeys I frequently stream like radio without much problem. I hope things improve.
I'm also in south east london
I get awesome speeds with HSDPA, but not so great with 3G.
I generally stream from last.fm and it pretty much stalls when on 3G. Web-browsing on 3G alone is also not that great for me.
This sounds like it's more a problem with the coverage than the phone though (althoguh it's interesting that a reboot/re-enabling mobile net fixes it).
Couple of things to try:
1 - Download a speed-test and see what speeds you're getting.
2 - Check coverage here: http://www.t-mobile.co.uk/services/coverage/street-check/
im having problems to , i spend half the time on Wifi and only use mobile network if im out and about, but im barely getting 3g and im in heart of england (birmingham)
I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance
.
do you ever enter a building, subway, or some other location where the GSM becomes poor?

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...
i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

do you have an old sim card? i had a 3g sim card that wasnt even 1 years old and replacing it fixed connectivity issues on my nexus 1 and i had a similar experience with my old htc magic

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time
I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.
Get a new SIM card.
same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone
did you guys see this other topic?

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430
Pls keep reporting..

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...
I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.
fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)
i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......
yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..
Chryssa
Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...
Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..
Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....
Hi all,
I flashed my phone, and thought I’d go with Darky's Raw Steel Edition (4.1), which is awesome btw. I installed it correctly, installing I9000XWJM8 first (the MODEM and PDA, not CSC as none seemed to come in the package).
Everything was working smoothly until I realise 3G/Data Network is no longer working (it did previously). Not only that but it seems it won’t connect to my service provider (Three) at all (emergency calls only), and I’ve also now noticed GPS doesn’t seem to work at all, I can’t even get into GPS test mode. Wireless does however work though it being off, or on, has no impact.
I’ve tried:
Flashing different firmware - Stock JM8 and Doc Froyo’s latest JPO.
Hard Reset
Deleting and re-entering APN settings, though they were correct and already on the phone anyway.
Testing my SIM on another phone – signal is strong, inc. 3G on that.
I’m really at a loss here. Any ideas anyone?
Thanks
UPDATE: So, I won't bump this myself, but incase anyone finds this thread in the future: the gprs, gps, 3g, etc all work - just not in my house, on the SGS, anymore. I have no idea why - my other phone, it's fine.. and it used to be fine with this phone too. I'll update again if I figure it out.
the other phone works fine with the same sim you are using in the SGS?
Yep, the same SIM works in my old Nokia 6600 fold, people in my house also with Three are getting solid reception right now. 4-5 bars with 3g established.
It worked beautifully all the way home from work on the bus, just not in/around my house.
It's as if the local cell towers near my house have blocked my SGS specifically (can't receive calls or texts either). I did turn the wireless on and off in short succession (which would cause the gprs/3g to try to re-establish each time).. maybe I flooded them and they blocked my IMEI? Or is that just a ridiculous idea?
The real odd thing is GPS not working either (again, just around my house/street); surely it doesn't need a cell site for that?
It does seem as if I can't download apps from The Market anymore either, and have tried various cache clearing solutions to fix it (problem occurred roughly when I noticed my reception was nill).
You might have a problem with the band selection thing of your phone.. have you tried downloading/speed test when you /do/ get a connection? If it seems capped at 40kbps, you might have the same problem I experienced before, of being stuck on 2g. (Despite settings saying otherwise).
I fixed it by doing the solution to having a missing 850 band, the thread of which is found somewhere in this forum.
Thanks. That sort of worked earlier.
It made a slow data connection, and some texts came through.
I then went out to a location a few miles away, had a look and it was still on a slow connection type for a few mins, then all of a sudden it went to HSPDA (with the occasional 3G flicker) and was blistering fast.
Now that I'm back home, I've lost all reception again and can't make/take calls
[EDIT] Clicking around my phone in the hopes of finding something: checked product code in my nv_data.bin file with SGS Toolbox, and it's showing I9000HKDKOR; whilst the backup is showing I9000HKDH3G - could I be on to something? I backed up my efs folder after rooting before doing anything else - so, going to try restoring that.
I have a hunch based on a 2 year old post (http://forum.xda-developers.com/showthread.php?t=445913).
From what I understand, Three UK piggy back on Orange's network when Three's 3G cell towers are out of reach. Orange don't provide Three users with the full service though, just 2G and I'm guessing they prioritise Orange customer traffic.
I think when I flashed my phone, I removed code commanding the phone to prefer Three cell towers. Without that code, the phone simply goes to the strongest/first signal it detects. I'm guessing in the area near where I live, it's Orange (or maybe any old network which is why I'm often getting Emergency Calls only).
This is all guesswork. I'm hopeful, seeing as if I quickly switch the SIM to my two+ year old phone, then I quickly get 5 bars and 3G.. unless the SGS's signal issues really are *that* bad.

Try see if you have the symptom of a missing band?
Hi Nwsk, I tried that before and assumed it didn't work, but actually the change isn't sticking. Which seems to be the case for a couple of others! Thanks for pointing me back to it!
[Edit]
Ohhhh dear. Now I have another theory (I really hope I'm wrong).
I've just read on a thread that some phones don't have the 850 Band, it's down to a lack of hardware support. I'd wager every Three UK branded phone sold will have the correct hardware as stock. I sent my phone back to Samsung for repair, they said they replaced the motherboard.. inference: they replaced it with one without the WCDMA 850 support.
Hmm, I'm definitely no authority on this, since I'm just guessing.. but I figure if that if was a true hardware defect, you wouldn't even be able to get it temporarily?
Are you using any 'battery-saving' type apps? Something might be messing up and keep reverting the settings. I had this occur to me a second time when I was trying out the superpower app here, I think it conflicted with another app I was using, and it borked out my network connectivity. Somehow fixed that after a few reboots, and lots of messing around in the phone debug menu with the 3g/2g thing, it suddenly worked again.
I've not seen it manage to get onto 850MHz WCDMA in my house for a while, not since the mobo got replaced (I should qualify that with a statement on my bad memory ). It will occasionally latch onto something if I walk around the house, giving me a slow data connection with the G symbol showing - it will drop pretty quickly.
Messing around while I write this, I've just realised if I set my phone to GSM(2G) with roaming [Three UK phones need this on so they can connect to Orange towers], then it does establish a data connection at 1800mhz. If I force WCDMA only, I get NOTHING. Setting both/auto leads to it being dodgy/instable, as I've discribed above.
My Nokia 6600 supports 850mhz UMTS, which would explain why it's working well inside my house.
I don't think it's an app. I've flashed a few different firmwares in an effort to get this fixed, it's currently on official Froyo JPO (not even rooted!) with Multi-CSC and a few completely harmless apps. I'd try the stock Three firmware if it was available somewhere.
I'm hoping it's software like you suggest! I will tinker away for now!
Thanks for all the help, at least now I'm fairly sure I'm on the right track!
