Vario II network coverage question

Recently my Vario II intermittenly loses network signals, it says No Network and I have to toggle phone off/on to make it search for signal again. This only happens when I'm at home (Charlton SE7 area).
Rom 1.21.110.3 (19/06/06)
Radio 1.05.05.00
Does anyone have the same problem?

Flash HardSPL first, then upgrade your radio.
Ive linked to my guides incase your unfamiliar with the process.
The newer radio should possibly increase your GSM efficiency. Are you in a decent area for reception?

Hi, many thanks for your detailed guides. I've upgraded Radio to 1.38.00.10 but the problem still persists. I'm in a very good coverage area, always get full bars 3G when it works. Soft-reset my phone and now it's searching in vain for network signal, I'm confused

What operator are you with ? Maybe the cell where you live is getting overloaded. We had a problem similiar to this last month when our local base station had a problem. Our work-around was to disable 3G but not using a Hermes . Apparently the handset tries to register using the 'best' data-bearer its configured for. So disabling 3G made it register with GPRS which worked fine. They then fixed the base station and we were able to re-enable 3G. I would
guess Charlton would have a lot of subscribers per cell. You would expect the coverage to be better in a built-up areas but who knows. Maybe an enquiry/ complaint to the operator would at least tell you if they know of a problem and if its temporary or longer term

Cheers for that. I'm with T-Mobile. What's bugging me is that this signal disappearance only happens sometimes. It's not that I don't have 3G (or signal for that matter) at all, I still get full 3G signals fine most of the time. But you probably were right, looks like it's a fault from the operator's cell in the area, I will give them a call next week to see if there's an explanation.

I've noticed this problem when I'm in the south London area (very general I know). People have got around the issue temporarily by forcing the phone to GPRS only

More problems! After upgrading to 1.38 and trying all sort of "good" radios like 1.17, 1.27, 1.34 I can't make/receive calls unless GSM is forced. There must be something wrong within my immediate area because with the same radios everything works flawless just 10 mins down the road. I just called TMob and there's no technical fault or anything from their side. I will just have to put up without 3G until the problem fixes itself

There are lots of people complaining about 3g on T mobile in UK. They seem to have serious issues with Hermes devices and the dropdown to GSM.
I had a problem six months ago with my hermes on orange at home in SW London. For a few weeks it was mucking about - I rang O who advised me that they were experiencing some local issues but would fix them within days. I switched to GSM for a few days. When I switched back its worked fine for last five months.

3G gone mad!
the same thing was happening to me. Full 3G reception in Leicester, tried to connect to get my e-mails and then the signal totally goes. The same thing happens when I make calls as well. Switched to GSM and everything worked. Now in York and everything is working on 3G.
Network is T-Mobile.

This sounds similar to the issues I am having.
Do you get the phone hanging as it attempts to start a call and then after a while a message stating that it was unable to connect?....sometimes resulting in a soft reset to bring the device back online? In my case toggling bluetooth will reset the connection.
I am with T-Mobile in Glasgow but get the same issues during the day in Edinburgh

No 3G

No mine doesn't say anything, it sounds "ding ding" after a few secs like when you press the hang up button. I can use the Internet but anything to do with calls is just impossible. I've switch to GSM now and everything's back to normal. A bit annoying can't use 3G at home.

"The person is temporary unavailable" very big problem..

Hi, I have Blackstone from Orange UK. I have a big problem. On 10 calls only 3-4 is good, the rest is "the person is temporary unavailable". Sometimes after soft reset is good for half day. After is the same 3-4 good rest is faulty. Why is that. This is very big problem for me becouse I missing important calls.
Sorry for my English.

Any ideas for that?

Could you describe the problem in a little more detail please? Is it receiving and making calls that this message comes up?
Petrov.

This is only incomming calls (when somebody calling to me hear this message). Outgoing, text(out,in) are good. I was set manually GSM/UMTS band on UMST(850+2100)+GSM(900+1800), (before was auto) and now is a little bit better than before. On 10 calls 8 is good
Sorry for my English.

2G sounds like your solution!
your problem as is/was mine, orange has a great 2G network, however they have this very bad habbit of setting all their new phones to goto 3G, i live in wales, and find 3G - to be NIL. So i set my phone as in the earlier posts, to the 2G setting, it cures battery issues, and ensures u have a virtually 100% call rate.
Try it, you'll notice its alot better, either that or you've a duffer, in which case get rid, they'll send you another brand new device if you've had it less than 30 days, its your right under the consumer goods act.

I did like you wrote. And is very good!!! But my question is: for what is 3Gconnection? Only for video calling and faster internet? If is that than i don't need a 3G connection.
Sorry for my English.

troxter!
i had the exact same problem with my diamond, tried all available radio roms and settings without succes. i went to warranty and they said that the mainboard of the phone must be replaced. after 33 days in service i managed to get it replaced with a new one. your phone is defective! i am almost sure! go to warranty!

Hi!
I bought this mobile 17th november 2008. Can I exchange on new phone in Orange shop? I bought phone in normal shop on Wimbledon. For e.g. I will go tommorow to orange shop at Wimbledon with broken phone and they give me a new one?

My guess is the phone is updating data and you are on a 2G network. No simultaneous voice and data, so the caller gets the unavailable subscriber message. I would try setting the phone to GSM only, if you are in a 2G area.

Although not as serious, I have the same problem on my Motorola L7 on O2 (Presumably 2G)

I live in south London, so coverage of 3G is good(on Nokia N95 was 7 bars on strength). However, when I set manually on 3G or auto, signal strenght of 3G is only 2 bars. When i set on GSM is full strenght of signal(4bars). Question is:
Is this a problem with phone or with Orange Network?

Problem with Hero on T-mobile UK

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)

HD2 phones missing calls and hanging up mid-call

Hi all,
I work in a company who have just dished out over 100 HD2 phones to their staff... we're on call and are having some problems with the handsets missing calls and dropping calls mid-call, and I just want to know if we're alone in this, or if it's a common problem, or better, if anyone knows of a solution!
We use Orange (UK) as our carrier, the phones are NOT orange branded....
When we get a missed call, we can be in an area with good coverage (3G or otherwise, it doesn't seem to matter). The person calling us gets a ringing tone as normal, but the phone doesn't seem to do anything (ie, no indication that it's getting a call coming in). Once the caller has given up (or been directed to answerphone) we do seem to get a message telling us that we've had a missed call, but this is a text message, not a windows mobile message, and can be upto 4 hours later!
We've also had situations where an HD2 has rung and we've picked it up after one ring to be informed that the caller was about to hang up as it'd been ringing at their end for over a minute!
The other issue we have is with the phones dropping calls mid-call both when taking or making a call... The phone handset shows good signal even when it drops the call... At first we thought it was people touching the hangup button on the screen with their cheek, but I've now witnessed the phones do this when held away from the caller's face and even when it's been on speaker phone waaaaayyyyy away from anything that could touch the screen or buttons...
Oh, and we're running software version 1.66.405.2 on all of the phones, and it appears that the problems are occurring on many (if not all) of the phones... They're all running BsB Tweaks and have all been setup in exactly the same way...
Anybody got any ideas? They seem to be a lovely device for everything else, it just seems that the actual telephone side seems a bit flakey...

lol... every problem you just described was happening to our company when we were using the Orange network in the UK.
We left Orange exactly one year ago after almost going legal with them due to their extremely shoddy service plus underhand and downright illegal activities with our account.
To cut a long story short...
When we took out our contract we bought every line as sim only and Orange gave us a hardware fund to buy our handsets as and when we needed them.
Turns out though... every time we bought an offline handset they were putting it through as an upgrade! This obviously increased the length of contract for the each connection in every purchase. The very definition of an upgrade in Orange's own terms of service (at that time, they may have changed it now) did NOT include buying a handset for a SIM only connection.
On top of this we had the exact same network/service problems you describe with ALL of our handsets (including the non winmo ones), plus many other other issues with their network/service.... missed calls not actually ringing the device.... text messages delivered late and voicemail notifications sometimes up to 6 days late. Dont even get me started on the dropped calls.
When it came down to the month we were supposed to be out of contract Orange told us that we were still in contract and we owed them £70,000 plus the full price of all of our handsets if we wanted to leave!!!!
Well... we told them they were talking rubbish and after a lengthy process going back and fourth with their legal department they eventually admitted defeat. They didnt have a leg to stand on really so Orange didnt get a penny and we kept all of our hardware.
Apologies for the lengthy post there i was trying to keep it short and keep my post in context. What i am trying to say is...
In my opinion your issues are more than likely down to the Orange network then anything else... but they will REFUSE to admit a problem. They also will not support your handset if you didnt buy it directly from them.

Having the exact same problem here so it can't be a carrier problem. This issue goes hand in hand with the switching of bands problem reported in another thread. The only solution as of right now seems to be turning off 3G network-capabilities completely until we get a radio that functions as it should. Would you mind contacting HTC? I think that a company threatening to sell their devices due to bad support on their part might make them do something about it. Us regular consumers they just ignore.

imo... its definately a network issue....Which carrier are you using?
i have HD2's on Vodafone and T-Mobile (both UK) and do not have any of the issues i had previously with Orange (didnt have HD2's at that time though so maybe its just unbranded HD2's on Orange?)

The same carrier I used on my Touch HD and had no problems with(Saunalahti). Going to try the new 2.09 radio and see if that solves my issues.

Which country?
It would be helpful to actually post some details!
Like i said above... it could be the HD2 on your particular network that has an issue.
I really dont think its a handset problem as if it was literally everyone with an HD2 would be going legal!
Ive been using HD2's since Novemeber 2009 and havent encountered any of the problems described in this thread.

My HD2 is switching networks and dropping calls whenever it feels like it. Currently using HSDPA only with GSM + UMTS. I'm guessing my problem is more related to the switching of bands than anything else. Why it would loose its connection from one second to the next is beyond me, but this is a known problem.

Thats a slightly different issue to the OP. Your problem does indeed sound like it is down to band switching. There are a few threads on these forums about this as you already know.

I know, but I think the underlying problem is still the same - I've had plenty of calls dropped even when having full bars. Could be a carrier problem, but due to the amount of people having similar issues I'd say it's a hardware/software problem.

with the band switching issue im unsure... i dont have the problem on any HD2 so i cant possibly comment what the cause could be.
But the OP in this thread has other issues unrelated to to the band switching problem... voicemail notifications delivered late... calls being missed due to phone not even ringing etc... these are NOT related to dropped calls caused by band switching. Im 99.99% sure they are network problems having seen the exact same issues on the exact same network myself.

Maybe he has both problems? shoddy network service AND the band switching issue?
who knows as he hasnt posted back?!

What's interesting though is that we've previously had HTC Touch Diamond 2s, Touch Pros, iPhones (although only a couple) and standard Nokia boggo handsets with the same provider (Orange UK) with no problems.... It's only the HD2s that seem to be affected by these problems...
I'm not sure if it's a band switching issue... is this where it drops from 3G to GSM (or the HDthingy half way between!)? I have noticed the phone drop from full 3G to the H symbol at times for no apparent reason...

er... you do know that H is faster then 3G right?
Its goes like this: HSPA>3G>GPRS>No data/only GSM
I assumed that you knew this if you were supposed to be supporting mobiles for your company.
If you have only 1 bar of HSDPA/HSUPA it is still faster then 4 bars of 3G.
Also... i sort of got at this in a previous post but the Orange network does not like it if you use handsets on their network that are not bought directly from Orange themselves. Your story is oh so familiar to me.
What i would suggest you try with one or two handsets is flashing them with an official Orange ROM for HD2. This firmware must be floating about somewhere as i do believe Orange have the HD2 on their books.

I don't support the phones, I just set 'em up and give 'em out... I'm a broadcast engineer who supports IT and Radio broadcast studios, not mobile telephones... as I said in my original post, I am on call with an HD2, which is a company phone and is dropping/missing calls... I just came on here to see if it's a known problem with HD2s, and if there's a solution, or if it's likely to be something with the network (Orange) which we may be able to jump up and down about and get them to resolve...
I had remembered it the wrong way around with HSPA and 3G, so thank you for clearing that up for me...
Is the band switching issue when it swaps between each then?

nobody else got any ideas?

*tumbleweed passes....*

I'm having similar issues on AT&T in the US. My callers get a fast busy after my phone rings a couple of times. It does not forward to voicemail. I have to force the phone to GSM then call the person back. UNACCEPTABLE.
Sometimes they get "all circuits are busy" message too.
Did you ever geta solution? My 3 year old x7500 is a better phone than this HD2 is at this point.

They probably won't tell you what equipment they have in your area (due to security reasons) but if they have Motorola based cellsites, then you're going to get these issues as the radio equipment struggles to pass from GSM to 3G and back again.

You are not alone........
I don't think this problem is necessarily restricted to Orange; my company had the same problem when rolling out un-branded Touch Pro devices to our users....and we're on the O2 network in the UK.
Our users experienced exactly the same symptoms - calls dropping, unable to answer calls before the other end hung up, etc...
It wasn't until we installed a ROM update from HTC on all the handsets that the problems....um, lessened...they got better but were still present at a much lower level than before.
I think that one poster has already suggested trying a different radio (i.e. the bit that actually handles the calls/band switching etc.), which is separate to the software (version 1.66.xxx in your case). There may be an HTC ROM update on their site - these usually include software and radio updates in one. You can find your current radio version by going to Settings | About Phone | Software Information - it's listed as "Radio Version" (and the latest is somewhere around 2.10.xxx - taken from a T-Mobile US HD2 I think).
When networks brand the HTC handsets, they also test the various radio ROM's on their networks, before loading a (suitably bloated) software ROM and known-working radio ROM onto the devices before shipping. This, in most cases, is something you can try loading on your unbranded devices - not so here, since Orange never released the HD2 in the UK (ok, don't shoot me - they did release it in very small quantities on their business tariff before pulling it due to "issues found in testing"), so they sure as **** didn't release an updated ROM for the device.
Your best bet, if you can't find an HTC ROM update later than 1.66 (which I don't think there is...yet), is to get involved with this forum in the Leo section. Learn about flashing a new HSPL and then try some other radio ROMs to see if any of them solve your particular problem. You'll have to devote a day to reading/learning before you get down and dirty with a handset....unless you have a few of these £500quid beasties you don't mind turning into paperweights!! Only trouble with this route is, once you've found a radio that works on Orange (and doesn't rinse your battery in two hours!), you're gonna have to repeat the HSPL/radio update process on 100 handsets, then re-install/re-configure each and every one.
Not a very inviting prospect (we "only" had 45 handsets to do!), but the end justifies the means. The HD2 is a marvellous handset - I know, I've got one (on T-Mobile UK ) and I wouldn't be without it.
Keep posting any questions/thoughts.....we'll be here to offer our "useful insights" and "helpful suggestions" as long as you can take it!!!
Good luck!!!

s4 data connection issue comes from my 9505...

Helo all..
I just brought that phone s4 9505 lte version for 1week ago. And at that time I did not find any issues on my phone. As u know I only checked using wifi and play games. It seems to work well everything. But today I am realized that something wrong in my galaxy s4 particularly when I use data network. The main problem is in the H symbol that always appear in the top of the screen with 2 sides arrow. When I do nothing with my phone or idle for a short while, the data connection suddenly stop working which means u can not browsing at all even making a call and texting. So the only way is to refresh the network or change the mode or restart your phone.
I dont know why it always happen in my phone many times. I have tried to refresh network and change the mode then give back to the wcdma mode. It occurs same issues again after a couple hours. But I did not notice where I use gsm mode.
About my signal is good. No drop signal at all. But I always encounter that problem. Maybe anyone who has the same issue .. plz inform then we can try searching out the solution. Thx

Addition information.. I buy this phone from singapore comes with official local warranty.
Actually. I have not tried to change another provider and I hope this cell is not fault factory.
I will try with different area and provider first then decide possibility

Are you on vodafone? There is quite some discussion going on in german forums where the lte - 3g change seems to be problematic when on vodafone network with the i9505. If so you might want to check forums like android-hilfe.de or so. Btw. Im in switzerland on provider swisscom and have the same problems. Data connections drops completely every few minutes. Very annoing.

I just tested set into wcdma mode along night and until now it still work perfectly. This problem can not be predicted when it will occur. Sometimes I browse internet for 2 hours..afterwards my phone can not be used completely even testing and calling. I hope this is a provider caused.
