Cant find Network on Kaiser

Hi, I have noticed that a few have already complained about this issue
I'll tell you what happened to me:
I went on holiday from Israel to Jordan for 2 days.
My Kaiser did not roam as my sim wasn't open for Intl. Roaming so it couldn't find a network.
Also I did not charge it so the Battery went dead.
Following that two days I got home gave my Kaiser a full charge and could not get the network back.
I have done many Soft resets, 2 hard resets & spoken to HTC Help Desk.
The only thing HTC could tell me was to send the Kaiser to the UK for repair as they have not heard of this issue before.
Obviously I do not want to send it as I am sure it's not hardware but something else only.
My Kaiser was perched in the US (made in GB)
Network is Cellcom , which by the way I have tried other Sims in me Kaiser since this happened but with no success.
This issue is very frustrating as I feel helpless regarding this issue & I don’t know what to do
If any one has an idea ………….Thanks

First, try just removing the SIM card, then re-inserting it to see if the phone reconfigures itself. You may have to do a power on without sim card, before you re-insert it.
If that fails, do a hard reset so it goes back to factory default settings, then the inserted SIM card should set up the phone settings properly.

Thank, but like I said before……
I have done 2 hard resets tried every way of rebooting with sim / without sim
Nothing works !

hello saper747:
mine switched to flight mode and swap back,it cant find network any more,too,no matter hard-reset or flashing rom,its still.........
looks like we got the same problem, is yours telling "no sevice"? just a "!" on the service icon,right?

I think this MIGHT be a bug/issue
I had this last week for almost 4 hours. I dont think the network was down but if it was then T-mobile did not state anything anywhere
I had reception all day and then suddenly around 5:30pm, I lost it and did not get it back until late evening

Hi , yes its the same problem
It shows the networks arround but it can't register to them only the !.. icon
This has nothing to do with the network carier as the sim works in all my other phones .

Hi i was wondering if anyone has a solution yet ?

I have THE SAME situation. I believe this is the bug which MUST be solved by HTC! Or at least by someone. I still haven't found the solution. Have anybody done??

Has anyone tried what happens when 3G is disabled (GSM mode)?
I'm having the same problem for the last couple of days in the UK with Orange, but when I switch to GSM (Settings->Personal->Phone->Band->Network Type = GSM) it works fine.

I tried to do that - no result. I have made hard reset - no result. I have dowloaded update WM6.1 from offical site HTC and installed it - no result.
Also, during two days, I calculated at least 20 persons who had this problem around the world. I can not believe that nobody researched this problem yet!

Me 2
I am also suffering from same issue.
My kaiser drop network at around 5PM till 1 hr approx, it hapeend for a week almost then I update radio then it was working ok, but still its not permanent solution.
Now a days my kaiser leaves network anytime and then it will not connect how hard u try, reset, hard boot, flash anything and after sometime suddenly it works.... magic.
I check sim with other phones its working gr8. but with this phone network gives trouble, I dont have 3G here in India, so its running on GSM.
Please somebody find solution, I'll post if I get any solution.
Thanks,
Dilip

Did you try with manual selection of mobile network (start->Settings->Personal->Phone->Band->Network)?

i did the network setting and put it as GSM and it works like a champ
BUT
i lost the 3G capabilities. One of the reason i purchase Kaiser is because the 3G capability.
using other Kaiser will give me a full 3G capabilities so i start wondering whether this is a hardware issue or software

No-one one here experienced the 3G bug then?

This is a problem where you have an apparently good 3G signal BUT you cannot make or receive calls or texts and you can't establish a data connection. There is no obvious sign that you are in this state until you try to call, text or access data.
The "solution" from T-Mobile in the UK is to force the phone "band" setting from Auto to GSM, then it works. But of course its not a solution as you lose 3G.
If you are at work with a 3 icon on your phone, just try calling it from your desk and see if you get straight to voicemail or not.
After discussions with T-Mobile they are sending me a replacement handset but if the postings in Modaco are anything to go by then I am not alone in this.
What is not clear is whether this is restricted to:
1. The T-Mobile UK network
2. The T-Mobile UK Vario III firmware
3. A combination of the above
4. A general design fault with some Kaiser's
This is being discussed in the Modaco forums but I couldn't find any mention here.

I make dozens of calls, and send around 50+ SMS a day.
No problems in the last month.
I am an Australian Kaiser owner running on the Three network.
ROM: 1.81.861.0 WWE

Hi there,
I have the same issue on T-Mobile in Germany.
What I have not been able to figure out is if the phone works again after a while or if one needs to reset (as I always do).
Regards,
Martin

I have tried soft resets and even a hard reset and it appears to be random whether it starts working again. This seems to be same experience as the Modaco users.

Well, I worked for T-Mobile UK recently and had the very same issue on my Vario II, even whilst at work where there was a large mast and the 3G coverage was the strongest in the country.
on further investigation, everyone else in the area had the same issue. sometimes it would work ok, a lot of the time i had to manually set to 2G just to be able to use the phone functions.
in T-Mob we could check the strength of various 2 & 3G signals by postcode, and the signal in the area was very strong, with no outstanding work issues or problems (according to our system)
was never able to figure out why this was happening, and nobody was able to answer the questions.
so -
seems to be T-Mob UK (perhaps just in various areas at various times), and is not limited to your Kaiser / Vario, so at least you can relax cos it's not a faulty phone

Thanks for the very useful post. Unfortunately that doesn't give us a solution. If this cannot be fixed then T-Mobile is useless for me.

i've been experiencing the same - no data access when using 3g (whilst showing 2 bars) but connecting fine using gsm.
can anyone point me in the direction of a replacement comm manager with the same icons as the default kaiser but with a 3g switch in the vacant slot ?
i've been looking at a few replacement comm managers but can't seem to find what i'm looking for ...

This is NOT a problem with your Kaiser, replacing your phone will not make a difference. It is problem with your provider's tower hard/software. Strange that T-Mobile has not told you this when you contacted them about it.
T-Mobile in the Netherlands does not have this problem, but the KPN network does. KPN is however in the process of replacing the faulty hardware (or maybe they are already done now, even) and suddenly the problem disappears

Found the solution!!
Hello,
I had the same problem untill one day I inserted my sim card in another phone (a very old nokia - as basic as it gets).
For some reason that I don't know, when I put the sim card back in the TyTN II it was working and keeps on working.
This has happened over a month ago, and I now don't hv a problem.
Try to do the same, see if it works for You
Regards
XTP

Nope, I already tried the SIM in another phone (an SE W880i) and it was okay. I put it back in the Vario III and it still didn't work.
I also tried soft and hard resets.

i can confirm that this didn't work for me either. :-(
worth a try though ...

I had this with a Hermes on Orange UK a year ago. They admitted that the local cell was faulty and was being fixed and asked me to go to GSM for a week. After a week I switched back and it was fine.
Am now using a Kaiser (O Tytn2) in same location and its fine.

well i know ive been having problems sending mms whenever im on the 3g network, but as soon as i switch to gsm then the mms sends fine!

This is correct, the problem is indeed not your Tytn II. I've called with a dutch provider (Telfort) which makes use of the KPN network. And it is technically not possible. So we must wait till the provider makes sure this is possible.
I also was surprised that they never told me this in advance. Actually they didn't knew it was an problem till I called them.

Er, exactly what "is not possible"?
3G to 2G switching works fine on my other phone (an HSDPA-enabled Nokia 6120 Classic, on the same network).
So how can this not be handset related? I can see how it could be a combination of the phone and the network but if other handsets can cope then it must be related to the handset in some way.
Incidentally I am now using my replacement Vario III and so far so good but its early days yet.

which ROM versions are experiencing this problem?

I get this in the UK on a Tuesday at around 16:00 and then all is ok after 17:00. If I turn off HSDPA then this does not happen at all.
My view is the T-Mobile network. Being as I know when it happens its not a problem but I think they have time slots for software upgrades etc to the HSDPA side of things and this is when your phone goes into a GSM lockout.
If I keep the phone on 2g then it never happens .
This also happened on my N95 on the same day at the same time also , so i would guess its a network thing

I had this occur again this morning, on the new handset. I tried to call home with a full set of bars and the phone in 3G - the call wouldn't go through.
Switched to 2G, call goes through.
The problem is that when you are in this mode there is no way to tell, without trying to make a call. Your phone is effectively useless as no-one can call or text you and you can't call out. You are blissfully unaware.
This is not an acceptable situation.

I have suddenly started to experience this problem on T-Mobile UK, starting last night. It finds a 3G network, but I cannot receive or send calls or SMS. If the network drops to 2G, I can generally receive texts, but it's only if I lower my band to GSM only that I can make or receive calls, or use data.
T-Mobile are generally crappy in my area anyway, my phone is forever flipping between 2 and 3G. Can anyone confirm what 3's coverage is like in south london (stockwell area if possible) and what sort of data/call packages you can get sim-only, as I fear that they may not work out as cheap as T-mobile's.

incidentally, I don't think it's an MDA vario problem as I'm running the TyTn II.

Tilt: lost signal never recovers

Folks,
(I've searched around a bit and seen some reference to this problem but no definitive discussion. I apologize in advance if I missed anything and humbly request a pointer to the existing info if so.)
Just got a Tilt last weekend. On 3 occasions so far I looked at the screen and noticed that the phone had no signal (triangle with ! next to it). So for several hours each time, no one could call me. Going into comm mgr, the phone radio was still on.
This was in an area with no signal problems; soft reset or pulsing the phone radio in comm mgr would restore functionality with 3-4 bars. I finally nailed this down to having been in an area in the center of the building where I work, where signal gets lost. It appears that my Tilt never automatically recovers from a lost signal.
I saw this problem on the ROMs that came with the device and now it also continues with the new one that was just released by HTC a couple of days ago. In case it matters the phone is unlocked (using jump_spl and the other related tools and procedures found here, thanks).
Do I just have a defective Tilt? I mentioned this to others in my office and a few folks also claim to see this, and like I said I have seen *some* mention of this on the internet... I'd be astounded if this were really a problem endemic to all Tilts -- would people really put up with this?
Anyone have any additional insight?

It used to happen with me when I had the stock AT&T rom. I flashed the stock HTC rom and I don't recall ever having that problem, and now I've flashed SNE v2.5 and I don't have that problem.
My suggestion is to flash a new rom and see if that helps, and to make sure you're using a correct radio.

where do I get official htc radio and rom downloads?
hi folks,
where can i get official HTC radio and ROM downloads? I have an HTC TYTN II (acquired in Hong Kong) with ROM 1.56.721.3, Radio 1.27.12.11 & Protocol 22.45.88.07H just last month and already I'm encountering problems with the phone just losing the signal and staying lost and I'm considering upgrading however since my phone is brand new (practically), i want an "official" upgrade so as not to void the warranty. any help would be appreciated.
thanks and best regards...

I'll have to decide whether I have the cohones to flash an HTC ROM. Might at least be worth a try.

try this, go into comm manager, than settings for the phone (right soft key), than over to the Band tab, if I select the network type as GSM and leave the band on auto mine will contstantly serch for signal. i know this because my office is as close to a bomb shelter as they come and it never stops searching.
another good to this is battery life is improved
the BAD, if you want to use 3G you have to turn network back to auto and band to auto. not really a big deal cuz i dont have 3G here (yet).
a little workaround that works for me.

Thanks for that... I am running an AT&T ROM and even though I've supposedly turned on the Band tab in phone settings via KaiserTweak, I do not see a band tab. Should I?

I have almost this same exact problem! As of two weeks ago, my tilt started not allowing me to make calls
I then realized that it was also sending all my calls to voice mail. Thing is, the phone says that I have signal and has the Edge connection sign at the top. Whenever I try to make a call, the phone says "operation cannot be completed" or it will simply beep at me as if the call ended, right after it started.
A soft reset allows this to work. I've had this problem even happen right after hanging up with someone, and then trying to redial another number 5 seconds later. I doubt the phone really lost the signal.
Any ideas?

Hello

I had the same problem with my O2 XDA Stellar, it was fine for a couple of months, then I could hardly call out on it, email wouldn't send, could rarely go online etc etc. It seemed to be better on GSM/GPRS than 3G, HSDPA etc. I assumed it was a harware problem & as it was under warranty I got a replacement from O2 & it's been fine so far.

AT&T replaced the SIM card in my phone and I believe this has fixed the problem. I have lost signal many times (elevators, garages, etc) and it recovers each time.

Serious problem with Kaiser on 3UK

A few weeks ago, I bought an unlocked O2 XDA Stellar (Kaiser) from a work colleague. I put my 3UK sim in and had everything working well, but the next day when I turned on the phone, it wouldn't connect unless I forced it to use GSM mode.
The guy I bought it from put his O2 sim in and had the same problem, so he took it back to O2 under warranty. A week later it came back "fixed". It would appear to connect using 3G but it was impossible to make or receive calls unless it was forced into GSM mode, so it went back to O2 again.
Yesterday, I got a replacement unit from O2 and it worked perfectly with my 3UK sim.
Unfortunately, this morning it is back to only working if locked into GSM mode again.
I have heard of problems with Kaisers when they have been roaming (3UK roams onto Orange if the 3G signal is too weak), but I can't really imagine the phone isn't compatible with 3UK since they sell these as well!
As my work colleague is now on holiday for 2 weeks (so it can't be taken back for 2 weeks), does anybody have any ideas, or has anybody else experienced this problem?
Thanks
BTW, it's still running the stock O2 ROM

ditch the stock o2 rom flash it that fixed mine when i got an orange tytn2 im also on 3 but pandg. dont mean it will work work for you but hey worth a try?

The first time I had this problem, I flashed one of Dutty's ROMs but it didn't cure the problem. It just meant I had to reflash the original and Soft SPL etc. before it went back to O2.
Thanks anyway.

I've got a HTC branded Kaiser and I've had nothing but trouble trying to find a suitable radio ROM. The stock HTC ROM was just plain lousy on Orange & O2 (I have both SIM cards) whereas my old Nokia & Ericsson work perfectly well. I mean SO lousy that I more often don't have any signal at all most of the time, regardless of location. I've lost count of the number of ROMS that I've tried trying to find that "perfect" one. Now I'm convinced that it doesn't exist and because of this, the Kaiser and HTC themselves are sh1t!!
I had one ROM (forget which one) where the Orange signal would go from full to nothing on about a 3min cycle.... off, on, off, on etc eventhough the phone was in the same location.
I know this doesn't really help you, but at least you know you are not alone. Good luck finding that Holy Grail of a ROM. If you do, let me know!

Thanks, but it went from working really well yesterday to not working at all on 3G today.
I haven't made any changes since it worked.
If I enable 3G, it connects but shows the carrier as "3G 3" instead of just "3" and also shows the triangle roaming symbol (which it always shows when connected in GSM mode, but not normally when using 3G.
I'm not convinced that it's a ROM, or radio ROM related issue, but I can't believe that both Kaisers have developed the same problem, and both within 24 hours of using them on 3UK!
I may have to try and get it replaced again and sell it on though I would be very sad to see it go.

I've had the same problem, i was wondering what that triangle ment, yesterday i started getting the Roaming notification, 3 is expensive enough without roaming charges!
I'm wating to get an 02 sim card anyway but im hoping i havnt screwed up my phone the GPRS icon still shows.

It appears to me that your "3" network is just too weak, therefore the device selects automatically the next available stronger network. Try setting your device on MANUAL NETWORK SELECTION and select the 3 Network.

Loosing network signal

Hi!
After weeks of flawless function my Xperia can not find my carriers phone network.
I have updated the phone to the new ROM but that does not help.
The phone finds the SIM card and asks for the code.
Strangly it can connect to internet through my carrier (Tele2).
But I can not get a connection to the phone network and make a normal phone call.
Is something wrong with the phone?
NO, cause with another carrier (Telenor) everything works pefect.
Then obviously something is wrong with my carrier (Tele2) or the SIM-card.
NO, cause when I put my Tele2 SIM-card in another device (Ipaq 6515) it works perfect.
The Ipaq is not a 3G-phone. Can that have anything to do with it?
I'm getting lost here, all help is appreciated.
(ORIGINAL MESSAGE
Hi!
After weeks of flawless function my Xperia has started to lose it's phone network.
I notice it after I wake my phone up from stand by mode.
It doesn't help to turn the phone option off and on in Comm manager, but it has sometimes helped turning flight mode on and off.
Other times I had to restart the phone.
This happens a couple of times every day, after long times of not using the phone. I have not been able to trigger this problem, so I don't know what causes it or exactly when it happens.
Strangly it can connect to HDSPA while it has lost the phone network.
I have also experienced som freezes when I'm flipping between the panels to much.
All help is appreciated, thanks.

It would be helpful if you could give us more information.
What ROM are you using
Which carrier you have
etc.

I'm using:
ROM 1.02.936.3
Radioversion 1.06.25.29
The carrier is Swedish Tele2.
In Sweden we have GSM-900 and GSM-1800.
Tele2 also provide me with UMTS and HSDPA.

Today the problem became worse.
Even after repeated soft restarts it refused to find the phone network.
Then I change SIM-card to another carrier and it found the network.
I also tried the SIM-card that's giving me problems in another device. Works fine.
So both SIM-cards works. I'm now gonna go with the new carrier during the day to see if the problem come back.
If anyone have any ideas, please help.

All I can say that Xperia sometimes looks for the signal a bit longer it should IMO,
but I also know that carriers have many many problems usually and they're also often responsible for signal drops in some places too.
I know that 'cos I was talking to my carrier many times about it and learned something about it...

have u tried hard resetting the phone or re-installing the software? ..
if u run the sony update software it will give u the option to re-install your phones software - not sure if that has the same effect as a hard reset ..
probably worth trying

Have you tried disabling 3G/HSDPA?
Chance that you have very poor 3G on your phone, whilst the IPAC is picking up ok 2G.

Thanks for replying.
I disabled HSDPA/HSUPA in the advanced network menu. But it didn't help.
I also tried to choose GSM only in the phone seetings menue. But I could not even change the setting. Just got an error message about not being able to change the network (or something similar).
Is there any other setting that might be worth trying?

Having worked for several phone companies a few years at customer service I know what the procedure is.
-First thing they do is ask you to do a "crosstest", try your SIM in another phone and see if that works.
-You'll tell them that you did that and everything works fine when you use another phone.
-They'll automatically conclude that there's something wrong with your phone (correctly)
-They'll ask you if you could do a hard reset ( You did that too)
-Then maybe they'll try and reset the network (which almost never works)
Basically they'll have no other choice then for you to return it and have them look at the problem / replace your phone.
I don't think we here can help you with your problem
Good luck and keep us posted

Get a new SIM card. I've seen problems like this before, and an updated SIM card solved it.
The best way would be to test your SIM card in a similar phone, the ipaq not being close because it's not even 3G.

I'm so confused right now.
Got my new sim card today, problem remains.
I call the carrier support and after they've looked the IMEI-number up they say that the phone is barred by an external operator. They won't tell me the reason and by what operator.
So I call the other carriers support and after they've done a IMEI-search they say that the phone is not locked in any way, by them or any other operator. After have been talking to Xperia support they come to the same conclusion. The phone is not locked but agree to that something is wrong, with phone or carriers, and they want me to try with a third carrier.

Final
I've handed in my phone to the seller and got another one back instead.
The end

Exact same problem
Howdy folks,
I have the exact same problem: My Xperia has worked fine for a month. Suddenly I can't register with Tele2 network (tried another Tele2 card as well that didn't work) for calling but have access to data channel so I can surf. Got told by the Tele2 support that my phone was fu**ed up. Got pissed off. Tried a sim for another provider (Telenor) that worked. Called the Tele2 support again. They noticed that I have an old (2g) sim, so they will send a new (3g) card to test if that fixes this mess. It should arrive late this week or early the next. Can't wait...
I'll keep you posted in this thread (or, if I should instead have made a new thread, a moderator may spank me and I will do better).

Nope, new sim-card didn't fix it. But I have found at least one other xperia-user with this problem...

bad GSM signal
I have a X1
rom 1.03.931.10
radio 1.10.25.18
protocol version 52.56.25.29W
and since from the start I have bad GSM signal I have like 1-2 lines onli and it go up to 5line but onli from time to time (and then it drops again to 1-2line or none but If Itray to call is working or I get called but I can berly hear them bicose of the bad signal) on O2 network and in T-mobile is the same no mather wher I'm in town or outside of town; I'm in UK
is the phone damaged?? or...
sry for my bad english

My phone does the same thing
My x1 has had no problem with phone function or network. However, from the last week, the signal began to be lost sometimes, and the machine turned off automatically. and finally today, there is no signal at all.
MY SIM card works with other phones, so, I thought it might be software problem, and hard reseted with new rom. However, still no signal. It keeps looking. Does anyone have the same problem, and hopefully, solution?

I´m using my X1i with Tele2 as my service provider,but i don´t have any problems with signalstrength.. Works just fine..

I know I should've introdouced myself first, and that this is a strange first post, but:
HOLY SMOKES!!!
Xperia has FIVE reception bars????!!!!!
I always thought that 3 is the max value, since it only happened once that it went up to three bars, rest of the time it's maximum 2, usually 1.
I am also on Tele2 carrier, in Sweden that is, and since yesterday, I have no reception AT ALL.
Nothing.
Tried turning off 3G(or whatever it's called), nothing happens.
Tested with 3 other cards (one Tele2, one Telenor, one Telia) - all seem to be working okay. Except that the Tele2 one has slightly lower reception than the others.
Tested with 3 other phones as well - iPhone 3GS, Nokia 5800 Xpress Music, HTC Desire. All of them worked perfectly. Full coverage on that super-fast network thingy(the 3G symbol on iPhone).
Internet is just flowing on other phones - but Xperia is just falling behind in the most important section - reception.
Calls get dropped (2/3 of the calls), I must send same message at least 3 times in order to get it sent, Internet is crappy - if there's any at all.
Any kind of guidance is mostly appreciated.
P.S. A bit of those numbers which seem to be important:
Microsoft Windows MobileR 6.1 Professional
CE-OS 5.2.19608 (Build 19608.1.2.60)
ROM-version: 1.05.936.9
ROM-date: 04/19/09
Radioversion: 1.14.25.55
Protocol version: 1.0.11842.32680

Since all of you seem to have problems with one and the same carrier (Tele2) why don't you simply switch to another one? I once had a problem that was very alike the one described here and after several unsuccessful attempts of the carrier to fix it I simply switched to another one and all my problems were gone.
