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.

I get a problem when I dial out...

I was confused... I cannot dial out any phone number... only can receive..
I try to install my sim card in another handset, it is work.
who can help me?
thanks.

Need more information to help
What happens when you try to dial out (any messages given)? Have you run through the Connection setup (under settings) for your country and operator (I assume it's a TyTN II we're referring to since we're in the Kaiser forum)? More information about your phone/ppc, sim, country and network may help.

Hate to ask the obvious: did you try a soft reset?

Where I dial out, the phone will alert "Bi Bi Bi Bi". Of course Tytn II... What you mean by "Connection setup"? in my Connection session, I only can find Tasks and Advanced but not country and operator.
I using Orange UK.
And soft-reset many times.
thanks.

Had the same symptoms occasionally when connected to 3G on my P3600. Turned out it was a network problem. Network hardware was upgraded a couple of months later and no more problems since (P3600 and P4550).
Try disabling 3G, maybe it helps....

how can I do that...

Read the manual or (translating from a German device): Phone -> Menu -> Options -> Band -> network type : select GSM.
This may or may not help, but it´s worth a try.
Good luck!

I have followed your guideline but still not work...
And I cannot access to 3G, GPRS now... Crazy...

My mistake......you should of course select GSM - typo in above post.....
If it still doesn´t work, I´m afraid I´ve no more ideas

Opposite
I have quite the opposite problem on my elf - Outgoing calls are possible, but no incoming calls. This sim card works fine on another phone, but does not work on another touch. Other sim cards work fine.
Any ideas anyone ?
( I know it's the wrong forum, but am desperate .

Cool man. It is work. But Do you know why I cannot set as Automatic? is that mean I cannot use 3G now???

Looks like it is indeed network specific. You might want to contact your provider and see if they are aware of any problems. As I said, my network did have the same issues occasionally and I believe Orange in France had some troubles as well about a year ago or so.....

Well with my (HTC branded and non network customised) TyTN II, Connection Setup is the name of an icon in Settings, Connections Tab. It allows me to select the country and network and the program configures the rest.
I using Orange UK.

Ah that may explain it. If you have an Orange provided version of the TyTN II, they may have customised the options on your phone to remove that program/function. Connection Setup is explained in my manual immediately after the section on Comm Manager (pg 163). I'll be interested to hear what your network provider has to say about the problem.

Problem Text Messaging outside of my home!

Hello guys, i'm about to pull my hair out from frustration! I have an unlocked Tilt, on T-Mobile running on the HTC windows 6.1 Rom and for some reason i cannot send or receive text messages if i leave a good distance from my house!
Once i'm near my house by a block or so i'll receive and send text messages no problem, but there are patches around my town where i can't send or receive it. I tried switching my Sim card to an older phone and texting where i couldn't text on my Tilt, and the texts went through no problem, i just need to know if it's my phone or the carrier's fault. I plan on testing my Tilt and Wing in the same area's to see if that can shed some light, but i need help!

What's the reception like? You might try flashing a new radio, might give you better reception in some patches. What wm6.1 rom/radio are you using?

Currently my Rom Version is 3.03.405.0 WWE
Radio Version 1.64.06.04
I've tried countless rom's at first i thought it was because of windows 6.1 so i tried the HTC Windows 6.0 rom which didn't work either.
If you think i could use a better rom would you please let me know, i'm willing to do anything to fix this problem!
Thanks

i think it has nothing to do with a better rom...its just if the radio is fitting for the location u are at

well i don't know for sure that changing the radio will make any difference but it might help. you're having that trouble just with the sms huh? and always only in those areas?

Yeah it seems touch and go, in some places it refuses to work, but in others, such as my home it works flawlessly. It even worked on the freeway on the way to Canada, and even in Canada on Roger's network. I tried calling T-Mobile and they thought it was weird how it works in some areas but not others.

Please make a follow-up post to let us know what your findings are. It's an interesting problem you're having, and your data could be very useful for this and other issues!

So far tried a number of different radios and still haven't fixed the problem, but i've singled out the problem as the Phone, as i tried texting in places where i couldn't with my Tilt, on 2 different phones, one being the Tmobile Wing and they went through with no problems.
I'm gonna try Dutty's 6.1 rom and see if that changes anything, i'm pretty much trying anything that works now.

So just to be clear, when you use an unlocked Tilt on T-Mobile's network, you have difficulty receiving text messages. But when you put your SIM into a T-Mobile phone (Wing), text messages come through fine? If I understood your posts correctly, and my summarization is accurate, then it sound to me as if the Tilt is having problems accessing data services when its roaming off T-Mobile's network.
I would make a note of 3-5 specific areas where you have problems with SMS (ie 300 Block of N Maple Ave), and then call T-Mobile and ask them where their closest cell tower(s) is/are to those areas.
If my memory serves correct, T-Mobile uses GSM 1800/1900 in the US, but AT&T is still mostly 850/1900, and the Tilt may have issues receiving SMS messages while on a GSM 850 tower. You mentioned that the phone worked in Canada on the Rogers network, maybe they are on 1800/1900. Can someone from Canada confirm this last part??
These are just some thoughts of mine as I mindlessly watch TV, so who knows, I could be entirely wrong...

Hmmm interesting, now if i informed T-Mobile of this problem is there any way to remedy it without having to go back on a Tmobile phone?

is your tilt set to text through gprs or gsm? that might make the difference..

If it is an issue with GSM 850, then you may be stuck with running cooked ROMs based off of AT&T originals since their network still supports this frequency. To my knowledge there are no WM 6.1 ROMs with an AT&T base currently available.
It could also be a hardware issue... The section of flash memory on your device that stores the radio could have bad sectors (GSLEON3 would be someone who may be able to help you check this).
How did you come to get the Tilt? If you know someone with AT&T service, you can have them put their SIM in and then call AT&T Warranty and get the phone replaced under the 1 year warranty.
EDIT-
Second thought... Have you tried to force the phone into 1800/1900 GSM through the Band Settings tab under Settings --> Personal --> Phone --> Band ?

Currently it's set as GSM, do you think i should change it to GPRS?

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

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.

Dropped signal on v1615 t-mobile uk

I have a strange problem with my Kaiser, the signal with t-mobile uk keeps dropping, I have changed various radios and roms but still have the problem.
Current Phone is: V1615
KAIS130
SPL-3.34.Hard
CPLD-8
Current RomDA Ultimate X-V3 (but have tried anumber of others including stock t-mobile)
Current Radio: 1.70.19.09 (but have tried a number of others)
Any help would be appreciated.
p.s. Yeah on my first post, been a lurker for far too long.

Do you use 3G networking?, if not, try to change under Band menu to GSM network, it works pretty well and most places has good signal for it.
Good Luck!

I've had a nightmare with mine on T-mobile..
3 months ago, my phone developed a problem where it'd drop its network for a few hours, then I'd get a few hours of it working, etc. etc.
It was sent to T-mobile, who just re-flashed it. Still didn't work! Had it sent back and it was away a long time, I believe they replaced the motherboard.
It's been working perfectly for the last month until today - When it hasn't had a network connection the whole day! I'm worried it's still broken..
Hopefully our problems are network based! T-mobile warranty returns are terrible.

Aha! Changing my "Network Type" to GSM from Auto fixed things.
...But now when I receive a text, it vibrates until I reset!

turn off vibrate

Hi Milmirex & Jamiepyrite, thanks for the comments.
I've changed to GSM and it has been working fine for the last ten minutes, will test for the rest of the day and report back.
Does anybody else have any idea's how to fix 3G problem? I receive emails all day so could really do with this being resolved.
Does anybody else have same issue but with different network? would possibly point to hardware issue if you do.
Thanks again.
P.S. I didn't have the problem with vibrating on receiving texts

I had flashed back to the original T-Mobile ROM when it was doing the vibrate thing. Flashed it again back to the ROM I was using before and all works fine now

Even I have the similar issues from last week. Mine is MDA VARIO III. Even after changing my band to GSM, the issue stil seesm to be there. For about 10 mins i get a weak sigmnal, then it disappears.
Where did you get the original TMobile Vario III ROM. I would like to reflash and see if it fixes the problem. Can you please direct me to the right place
Thanks

I think my problem may be similar. I'm with Virgin Mobile but I think they use T-Mobile network.
Have had my Tytn II for over a year & haven't touched software or settings for several months & all has worked well. For the last few weeks I've had no signal in places that other people on the same network (using different phones) are fine. Sometimes if I reboot it comes back. I'm also now finding low battery a lot but I think that the signal issue is draining my batter as it seems to be constantly searching. I get low/no signal with a completely full battery so I don't think that the battery is the problem.
Might this be a H/W problem? Anything I can do to sort this?

i have the same problem. I use Telkomsel operator in indonesia. My Kaiser is HTC Brand.
Any idea why is this happen? Seems like A LOT OF Kaiser went bad this way
Anyone have solution?
