Xda II, Phone Edition or Moble Network Problem ??

I've had this problem for some time now and I have no words to describe this symptom ... I know I'm not alone as I know a few other people have the same problem:
The signal bar on Xda II shows ok, green LED still flashes like normal, even my Phone Dashboard showed that I'm connected to my mobile operator with signal strength >90% ... Nothing is suspicious until you start making calls, everything stays at "Dialing ..." and there will be no dialing tone !!! Make another call, same ...
Then you'll use the landline to call yourself on the mobile, it goes to the voice message ... All those time, you were actually not connected to the mobile network! When you realise this, the only remedy is to turn on and off Wireless / Flight Mode.
Now, have you had similar experience ?
I think, somehow the mobile network lost you, and Xda II didn't even notice it therefore did not bother to reconnect as it thought it was still connected. Is this it ? Or anyone has any other theory or solution to this irritating problem ~ which I genuinely have no idea who to blame ?

i think i know what the problem is
:idea: try to download and install this software,
http://www.gb-soft.cz/xdaii/product_gprs_tweak_en.htm
and in "gprs settings", disable "gprs always online", and set it to "search gprs on start gprs connection".
that way, you will be connected to your operator as simple gsm phone, not a gprs one.
the mobility managment in this status (imsi attached, instead of combined attached) is more simple to the network, and you won't lose service.
Hope it will solve your problem,
please update...

thanks i have downloaded it and installed, and set the "GPRS always on" to false, but the other one was default ticked ("Search GPRS on start GPRS conn").
i will start my observation today and see if the problem reproduce itself.

Chris
did this solve it for you?

Coming into the 8th day with this Tweak installed, with GPRS set to search on GPRS start (not radio start). So far, the network problem has not occured. I would like to give it another 2 to 3 weeks before announcing the problem solved.
However, just one little note, after installing the Tweak ... a day or two I noticed that the BT Icon no longer shows on the main screen task bar even after numerous soft reset. Not sure what causes it.

ISSUE : "Cannot connect. End current phone call.."

This is me trying to force a connection to the internet, but it wont cause it thinks its on a call. This is not good if you want emails coming down.
The only way I know how to over come this issue is to to a soft reset.
There has been no previous call. I open phone is inactive, I hit the red phone button. Nothing removes this obstruction.
Any ideas, how I can detect this or overcome this without doing a soft reset.
Q: How does one do a hard reset ??

I have the same problem. this issue comes when I've made a phone call and then I want to make a data session. my only workaround was is not to install programs like SPB GPRS monitor/etc...
If I'll have time, I'll install the newest ROM (the one that supports A2DP) and see wether the problem still exists or not...

I thought I had the newest ROM see my specs in signature. is that not correct. Whats this about A2DP ???

One solution to this is to use 3G (UMTS) instead of regular GPRS (GSM). 3G lets you use both data and voice connections at the same time. If you dont have 3G in the area (not sure why you bought a universal..) then you can try hard resetting by holding down the left and right softkeys (two buttons with -s) and pressing in the soft reset button.

This solution is not a right solution for me: when the Qtek is unable to create GPRS connections, it's also unable to create UMTS data connections. It says that there isn't modem on the other end of the line, etc...
The newest ROM is: WWE
1.30.77
1.30.1641.09.00
The other comment is that to use data and voice connections at the same time the network must be also capable of doing this.

Club Imate seam to be slow in posting new ROM they still show this ROM as the latest..

I have the same issue sometimes ... I usually over come it using connmngr to switch the phone off then on again ... the pain with this issue is that you don't know it's stopped unless you try to make a call or GPRS session :x

I am going to have to code something up Skschema to ensure 100% a connection every time on re freshing internet link.
Logic
Run Command Com
Turn off phone
Turn on phone
Run GSM connection
I also get other error messages like
- Cannot connect to modem at other end
- No modem found at other end.
The main point is if you dont have 4 strong bars showing internet connection will always be risky.
And as the Jas Jar ( O2 Exec ) cant have a direct fixed connection via the GSM jack on the phone, its only assistence can come from a wireless repeater for home use, and if you are mobile then the Booster cant be found as a fixed GSM connection cant be made to the device.
A repeater is not a booster.
A repeater is for home use when you are not moving. Hence wireless is ok. This is more for signal sending not receiving
A signal booster is required for mobile use and a direct connection to device is required ( not available to Jas Jar as yet). This is for both receiving and sending. Direct connection is the best option.
MAIN POINT : The manufactures should have done extreme testing with low bars signal ( say two ) as well as high signal ( say 4 bars ), with the use of signal repeaters and boosters, AND THIRD PARTY ADAPTERS....which they obviously did not do....

HD2 no signal, shows exclamation

Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.

has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?

My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.

I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.

This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK

Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?

so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).

Solved:upgrade your rom everything gonna b in place

Upgrade to what?

I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.

I'm having the same problem - NO SIGNAL
Any solution?

i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.

Since I upgraded to the Vodafone rom on the htc website I have not had this problem

I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs

Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working

Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception

Have the same problem
I have the same problem now, any solution for that?

Signal is vary bad

About few weeks ago my Htc Tattoo signal become to be very bad or sometimes full gone. Tried to flash different ROMs, insert different SIM cards, but nothing changes, signal is bad too. When i bought the phone, signal was perfect, becouse I live in a center of the city. So, please, maybe anyone know what the hell is wrong with my phone?

I heard, that it is possibility to reinstall something radio rom. Said, that can fix the problem, but where should i find it?

I have the same problem here. At the time i use the original HTC ROM my phone was connected with 3G and/or HSDPA, but now with fyodor i have the problem that the best connection is 3G.
I don't know how to solve the problem - maybe it is only a display error...?
Is there a application with wich i can test (or see - that is better) how the phone is connecten (GPRS, 3G, HSDPA...)?
kind regards
srkonus

Please, I really need your help. If I took the phone to the guarantee service, they just reinstall roms or something, and nothing changes. I tried to download one radio rom from there http://developer.htc.com/google-io-device.html#s4 but when I am trying to flash it, the error appears and says, flashing aborted. I am using Amon RA racovery if that means something. So, maybe now you can help me?

Try to change your network only to GSM instead of GSM/WCDMA.

I tried that... I tried every option, which is associated with connection.

I have the same problem...

Htc Tattoo is a very very bad phone...

Yea, I've seen this. After a week about, when I return from the trip, I will took my phone to service. They wrote me that, if it is held more than a month, phone should be replaced with the new one.

I brought Tattoo as a birthday gift for my gf,now it bacome the excuse of being late when we date......because she said she can not call me on time. and I never help her solved the problem.(both of us major is telecommunication in the university,what a joke.)
anyway I read the above and other topics.
and try to
1 turn to 'only gsm',
2 manully select oprator, there appears two local oprators, but no radio button on the UI, I'm not sure if it means selected. (do this at where signal is strong)
3 I try to turn on/off 'fly mode' at somewhere no signal.
4 flash other later roms.
no use at all.
on my table signal none. at the window signal full.
but it just 2m between.
my new wildfire and O2 mda is OK on the table, 80% signal.
I like HTC,I just don't sell it as 2ed hand,(half price now......)
I heard flash the Radio can make it better or solved, any one know the details?

Sms not received and sent anymore, bad call sound quality

Well...that's my problem...
I can't receive or send SMS anymore...
Last SMS I received did not make a sound or a reminder...I accidently clicked on sms tab when I saw it...
Last few had some problems with new messages notification...it just did not disappear for a lot more seconds as it should...
The second problem is incall sound quality...
I hear very bad and sometimes computer voice...
The person on the other end hear echo of his voice...
I had this echo problem for few weeks but it was very minor...
Now suddenly I can't use SMS and calling is so annoying...
And I am very sure these problems are connected because they started at the same time...
Top taskpar also does not bring up notifications menu...only start button works and battery bar is updated...
What could be the problem?
Software or hardware?
I am using EnergyRom, but never had problems with it...

I'm guessing a problem with Radio, due to the sms failure and robot voice in call. Try flashing another RADIO, it might solve the problem.
Sent from my HD2 HyperDroidCM7v3.1 using XDA Premium

I've been using radio and rom I have for more than 3 months...situation began 3 weeks ago...
If I flash the radio again...do I need to hard reset?

Hard reset may be a good idea & you can make a backup first thus can recover fully if reset does not resolve issue.
Are you sure sim card & network are free from errors ? have you tested sim in another device & another sim in your device ?
Does the signal strength apear in normal strengh parameters.
What network/country is this happening on ?

I guess I will reflash radio and new July4 rom because I use June1 rom...
I am in Slovenia, I use Mobitel network...I did not test SIM...Signal looks same as always...
I did remember something new...weather location says Slovenia and not city anymore...this has been since the problems began...and it doesn't update weather very often anymore...
Internet connection works well...
Probably flashing would be best option...if it doesn't fix the problem, I'll return the device to be rapaired...

Sounds more like a network change & perhaps your device phone band settings & sms centre number need adjusting ! weather failing to update &/or not pull actual location is normally always network tower related so I guess Mobitel may have done some reconfigering of its towers !
Really worth swapping sims & another device before flashing or sending into repair. Also a call to Mobitel may shed some light on any network changes if you get a brighter than average human call centre drone ...
