Cannot make calls while on 3g. Tmob advised me to switch to GSM as the solution!!

grrr
what a **** workaround!
that was their response... a **** workaorund that degrades my service..
anyone else had this or any thoughts on it?

Don't switch to GSM, switch to AT&T!
I am not a fan-boy for any of the carriers, but I must say that over the years I have gotten excellent service from ATT - except for when they changed to Cingular, which was a collection of regional companies with regional problems and inability to service - IMHO - a truly mobile client (like I live on the East Coast, but kept a west coast cell number - Cingular couldn't understand or deal with that one)...and the coverage is now better than Verizon's (not to mention the phones and the fact that you can do high-speed data and a call at the same time).
Did T-Mob start pro-rating their release contracts yet?

Don't know.
Am in the uk so cannot get at and t..
boo!

yep, get the same issues, whereabouts are you? im in rainham, and have to turn off the 3g to get reliable incoming calls and make calls, dont have to go too far and it works ok!
romford / ilford seem to be ok with 3g switched on.

I'm in Ilford and when set to Auto band miss calls intermittently so can't use that setting reliably. I wondered if there was a way to set the phone to use only 3G so it doesn't keep trying to switch between 3G and GPRS?

I'm from Indonesia and discovered that sometimes when my network switches me to 3G automatically, I can't receive or make voice calls.
So, I went to phone -> menu -> options -> band -> select network type to GSM istead of AUTO or WCDMA
Unfortunately, I left the 3G coverage area before I had a chance to see if it made any difference

Same here, in central London - have been ranting about this for some time over at Modaco eg here. Not a clear answer apart from perhaps swapping the handset but its hit and miss
Its a really severe problem and I'm losing the plot a little with it. Gutted.

BTW, if you need a way to quickly switch between the two modes, read http://forum.xda-developers.com/showthread.php?t=345524

There are about fifteen threads about this on here and on Modaco. Its a fact of life with 3g and HTC devices.
It is primarily down to relationship between the network cells and the device.
3G cells are notoriously unreliable and need a lot of maintenance - if you report a problem cell to your network, they may check it out - although they use their own testing to determine which cells need fixing.
Some devices do have weaker transceivers and hence the odd occasion where a device swap helps - but 99 times out of 100 its the network cell. And thus the reason that users find their device works fine on 3g in another location.

Poor voice clarity

I have been using the 8925 for about 3 weeks now. On occasion, my phone will act as if I have a weak signal. Choppy voice etc., on both ends even when connected to a landline. The signal strength will usually have at least 2bars, W/ 3G displayed. The phone will play audio & video W/ out chopping or skipping and this doesn’t always occur in the same area, so I'm unsure what would be causing this. Any comments or advice (pertaining to my issue ), would be greatly appreciated.

what network are you on are u using a sim or a usim
how old is your sim
do you have a spare handset to try your sim in?
have u raised this with your carrier? any known site issues in your area
have you tried manually roaming to see if this fixes the problem?

yea mine is also kinda poor too.
i have a cingular 3g sim card, i can put it in my sda and get full bars, but with this i get 2 bars most of the time.

they say this happends when your phone is connected to 3g and phone at the sametime. try turning off the 3g and initiating a call again

Turn off 3G?
I appreciate the replies.
1. I am on the At&T network
2. Sim
3. No spare phones to sim swap

Since I am located in a major city, 3G is on all the time. Shouldn't the device automatically make voice a priority over data once a call is made or accepted W/ out the user having to shut it down? Let alone having to tell the person on the other end; "Let me call you back, I have to turn off the 3G so my calls won't sound like shizit."
Tobe

**Update**
At&T told me they performed an over the air sync to my device. So far, I have not sen any improvement. I've even tried to shutdown the data before talking on the phone. Now AT&T is telling me to return the phone, since I only purchased it on Nov. 14th and they now believe the device is faulty.
Tobe

Here we go again
This is my second 8925 now & still the same thing W/ chopped up conversations, even when I have full bars and am making calls to landlines.
I have tried to disable the 3G prior to calling etc. Also, this never seems happen in the same area, so I don't think it's a coverage issue.
Is anyone else having this problem on the at&t network?
Thanks,
Tobe

I was having alot of the same issue until I upgraded my tilt to xda live 1.2 is current version. The new radio in that rom made a big difference in my neighborhood.

xda live 1.2

Diamond and UMTS is working fine? (Or worse than Cruise?)

Hello I bought the Diamond yesterday, I'm very satisfied except for the UMTS signal.
I already have a Touch Cruise (it didn't work in UMTS so HTC repaired it on warranty and now it works like a charm).
In the last 48 hours I had Diamond and Cruise one next to the other, and Diamond has always 2 lines less:
* when Cruise is in HSDPA with 4 lines, Diamond is in HSDPA with 2 lines
* when Cruise is in HSDPA with 2 lines, Diamond is in GSM.
Is this normal?
Many thanks in advance.
J.

Everyone has it i have also a TC and indeed, its shows always 2 lines more then the TD.

Same here my htc diamond has always two lines less than my htc kaiser.
The diamond has really a poor UMTS signal reception. I hope they will be able to boost it with a new ROM.

Same here
before with TC i got 2 lines 3G now non

Thanks for your feedback!
So it seems to be a common problem.
Today I checked during all the day, moving from a city to another city, half the time the Cruise had more lines, half the time they had the same.

Other feedbacks? Thanks

same problem here in austria. before i had full signal with my sony erricson t650i, now with the touch diamond i only have the half signal strength...

Well, it doesnt give many bars, but it works like hell here.
When using it as a modem (I often do on the road) I get speeds upto 150kb/s for browsing and emailing and that is just perfect for everything.

My 3G Reception is also VERY Bad.....
I´m using the latest Radio ROM 1.00.25.03.
Because of this weak 3G Recepion the Diamond changes to GSM very often, this eats the Battery up in about 6-8 Hours.....Even if I don´t play around much and the 3G Coverage here is excellent.....
Diamond: 1-2 Bars
Nokia E51: Always full Bars (-87dBm and up)
Hopefully Reception will be better with a new Radio ROM.
If it´s an Antenna issue.........DAMN!!!
I never had a Mobile with THAT bad 3G Reception.
BtW: GSM Reception is fair to good.... could be better also....

Poor 3G signal
That's right,
I have also very poor 3g signal, even though I live in the city area. I have also missed incoming/outgoing calls because the poor 3G signal.
That's not nice

same prob here (big city)
switched manually to gsm not to loose calls

Are you sure this is just 3G and not worse reception in general (ie due to smaller antenna in Diamond)?

in gsm mode i never experienced any trouble with calls.
in auto mode diamond switches to 3g (half signal strength), but one can't call me

Uh, this sounds even worse. Having a bad reception is one thing but showing a "fake reception" is a complete different level of bug.
Just to ensure that I did not get you wrong: You see a 3G reception (e.g. 2 or 3 bars) but the phone does not receive incoming calls and the caller is redirected to your mailbox instead?

yes, got me right.
in my case it's not the mailbox, just a message ("not available" or something like that) because of my settings, but that's petty.
thats why i manually switched to gsm. for using 3g (internet) i have to swith this back again.
annoying!

This should not happen, even when I have the minimum bars in 3G or H others can call me.
When you have full bars in 3G does it work?

same here, although i found that switching off umts and just using plain 3g solved the issues.

yes. when it's stable at full bars or even H, i can use it.
but i deacivated 3g anyway because of powersaving. only using it for web access.
there's a tool for switching 3g in comm manager easily, now i'm happy so far.

So, is it phone or is it just peace of s***?
Hi All
Do you have any fresh idea could it(lousy 3g signal) be hardware or software related issue?
The globe is full of small 3g phones without that kind of problem. That's why I really hope this issue could be fixed with the new ROM radio version...???
I hope I'm right, because if the pain is hardware related, we all have bought pretty expencive peace of crap -not the phone. It is not acceptable if the incoming / outgoing calls are missed!

Same problem, poor 3G reception .
Cruise was far better for receiving 3G signal.
Hope it is software only....

Intermittent GPRS / Internet issues.

Hi all,
I am using my Diamond on the UK Orange network and am having constant problems with the data connectivity over GRPS/3G. I have the phone synced to our Exchange server and also have an IMAP email account. It is set to use push but I often find the active sync in "waiting for network" mode rather than connected. If I keep hitting "sync", it will eventually connect and get my mail. I also find frequently that Opera times out and my IMAP mails fails saying it cannot "connect to server". Other times I can see the data connection restart or just go missing. I thought it was just my handset but after looking at a few collegues with Diamoinds, also on Orange, they seem to have similar issues. I'm going to bring this up with Orange but wanted to see if anyone had any ideas.
We are all running the official Orange 1.93 Rom. (With us having replacement insurance I am not keep on flashing a non official ROM via HARDSPL. I've had four Diamond already due to various faults!)
Any advice would be appreciated. data is a business critivcal function for us and currently either Orange or the Diamond are letting us down.
Thanks!
Steve

Hi i am on orange in nottingham and i am having the same problem i am running a offical HTC rom 1.93 and i cannot get online just keeps cutting out the data connection, if you call orange and get an answer please PM me as i need this fixing cos its getting bad now no internet on my diamond
Thanks

YIPPY me 3!! i thought it was just me with 3G problems!!
i'm also having issues making video calls and surfing the www via the 3G on orange i have looked and looked for settings concerning 3G and it's coverage and i'm drawing a blank.
i've called orange too and was told there should be no reasons as to why i'm having so many problems with it, as all things were normal and correct as far as they could tell and my location nottingham has 3G masts all over infact i was in the middle of 3.
i was wondering what effect changing the network type would have from auto to GSM/WCDMA and changing the GSM/UMTS band from auto to one of the others listed (too lazy to type them all out )
are there any tweek tools out there which can booost the signal reception?? it does my nut in to see the 3G icon flash up and disappear as soon as i try to use any of the 3G functions..

I've been getting this problem the last week or so too. Very odd as it used to work perfectly.

Problem with Diamond GPRS
Hello all,
I live in Tehran, Iran and I use Irancell network operator.
GPRS is available in this network and I could use it on my old cell phones such as SonyEricsson W810 and Nokia N81. But now I have HTC Touch Diamond and when I try to connect it to GPRS it tooks a long time to connect, showing "Connecting" but after a while it cannot connect!
Everything is OK, all settings, etc. I called Irancell but they say your phone is not compatible our network!
I think there must be a way to use this networks GRPS on my Diamond!
The first reason that made my buy this cell phone was its Internet capabilities...
and I know this networks use the same settings as South Africa Network Operator.
If anyone can help, please tell me.
Thanks.

Sounds more like a network problem than a handset problem imo. I hope I am not tempting fate but I have not had any problems with data connections on UK T-mobile. That said, I get a weaker signal than I do on my old MDA Compact III handset so I think part of the problem could be the internal aerial
The bottom line for me is that the Diamond is a good but flawed phone. ****e battery life and too clever, compact, aestheticaly pleasing for its own good
You get a very quick GPS fix for Google maps and sat nag though
Apologies for going off at a tangent

I'm on Orange, also in Nottingham and have been having this problem for the last week or so too.
Must be a network problem. I have to tap on the "H" connection icon, tap Disconnect and try again.

I agree that it's flawed, the biggest problem being battery life. The next biggest problem is that TF3D seems to be incredibly poor and half-finished. My solution is not to use it, that way you have a normal old-style WM phone but smaller, sleeker and faster with a VGA screen. HTH

Im all good here

I have a orange Diamond and live in cheshire, i have never had one problem with connecting to data services, always get a strong signal.
My phone is running duttys rom 2.3a (there are newer virsions, time of writing 2.7rc2) and the latest radio BS14, That radio is very quick at switching from Gprs, 3G and HSDPA, it has also increased my signal strenth a tad. its worth looking at that.Other than changing these, knowing orange it could be there network, it happens from time to time.

i have considered flashing my phone with a new ROM but since i've never done this type of thing before, i'm worried i'll end up creating a nice looking paper weight and with all the ROM's out there how do know which is best??

wrong answer edit.

Diamond drops from HSDPA -> G/3G during calls

Hi all, I'm wanting to know if anyone else seems to be experiencing an issue where during a call the signal icon will change from H to G and the quality of reception / voice also drops to what resembles a non-3G phone.
This seems to happen quite often regardless if the call is inbound or outbound. I can be sitting at my desk and have what appears to be full reception with the H icon, then 2-3 minutes into a call (still sitting at my desk) the icon will change to G and from the quality degradation it must be reducing to 2G... why is this? I could understand if I was walking around but it happens regardless and will never go back up to H during a call only once the call has ended... is this a limitation of the cell network/carrier?
I'm using Dutty's v4, radio 1.09.25.23, Olinex 1.93 hardspl. Network carrier is Optus and I'm located right in the middle of the city - Melbourne, Australia.
I'm wanting to try some of the newer Raphel radios but need to get Security Unlocked first - already PM'd Olipro... just waitin
Any comments ?

Hi,
Same problem to me... downtown of the fifth biggest city in France...
Don't worry if I may say so: the phone is the problem. it has crappy reception, probably the crappiest of all time... I have tried any possible Radio ROM available, none of them changed a signle thing...
Worst HTC phone ever made for reception... All my friends with way cheaper phones have at least four to five bars when they are at my place, I don't get that... but all my other phones do.
Eve worse: the phone totally disconnects from network when I have one or two bars of H or 3G... I receive NO phone call, no SMS and I am notified two days later (30 voice msgs, fifty SMS... all sent two days ago). I even had issues at work becaus eof all this, people complained they couldn't reach me for hours and days...
I now have to set it back to G alone (switch off H or 3G that I want to use all the time...), which is a shame for such an advanced device...

Correct me if I'm wrong, but you're not supposed to get a H during calls, maybe for video calls, I'm not sure. But for regular 3G calls, you shouldn't get a H, H should only appear when there is data transfer, like when using Internet for example.

I'm not really qualified to comment except from my own experience... My phone always has the H symbol, when there is no data activity then the H symble is faded/semi transparent and becomes solid as soon as I make a call or transfer data (eg. updating weather) and I never have the 3G icon - always H or G. I belive this may be related to the operator and the frequencies they use for both HSDxA and 2G modes.
Probably for about 80% of my calls I'll keep the H symbol, but when it drops to G it's really annoying as the quality turns to sh*t

My phone never seems to be able to hold a signal.
I'm on the 3 network in Australia & my phone doesn't stick to the network. If I choose options under the phone and press 'find network' a couple of times it will lock on, but then minutes later I get the 'searching for network'. Over & over again.
My phone is unlocked using the Olinex method, my radio is current & I can't even recieve incoming calls or texts...outgoing is fine (when I've got network0 & I can use browse the internet & use GPS etc...just nothing incoming...

i have a theory on this its called " crap design"! i thinks its because the internal antenna is towards the bottom of the device so when you hold it you are covering the antenna.
try holding the phone with just two fingers trying not to cover the back (below the battery ) this works for me! i only say this out of observation

Could just be the way the network is configured for HSDPA. Voice traffic can be pushed on to 3G (or release 99 as it is sometimes called) to reduce the loading on the HSPDA carrier / layer.
See it as a good thing

Most handsets I have owned usually drop from HSDPA or 3G or GPRS during a voice call, probably just a design feature to save battery life. Should latch back on after call though. I have to say though, I had the MDA compact IV and the reception is positively shocking! dropping signal is soon as I picked it up and i'm in a good signal area! On its way back to T-MO as I speak as this wasn't the only issue. Shame, great form factor as well.

Symbols on your phone are just that symbolic, they don't always mean what you think they mean.
If a UE is on your desk in idle mode and it looks like you have a great signal and a H displayed, great. It means that it is measuring the quality of the network and you have the ABILITY to hold a HS data session should you want. The reception barrs on most 3g UE's aren't a measure of the radio reception but of the amount of noise. More bars less noise, less bars noisey environment.
If you make a voice call, there is no way any decent network would use HS to carry your call as it is wasting resource somebody else could use and of course pay for. Once in a call the UE has to monitor many things and also maintain that call or data session. In simplistic terms if the conditions do not allow the call to be carried over 3G it will step down to 2G. If it was a data session it could go from HSDPA to 3G, then 3G to GPRS.
Also a network could easily by the swap of a 1 or a 0 carry your voice call over 2G without you knowing at all, freeing up that 3G network that cost billions to roll out and pay licence fees for, for data which they can charge more for.

I think they made a mistake in the International English manual where it says the antenna is located at the bottom. Either that or it's different for different regional phones. If you download the HTC Touch Diamond_Asia_English_Manual_Manual_080521.pdf or HTC_Diamond_User_Manual_Asia_WWE.pdf from HTC's site, it shows the antenna being at the top next to the camera.

The operators do not do this. Do they switch you to a land line when you call a land line, no. It is all down to radio quality where you are making the call and not what number or type of line you are calling. The phone networks are not that intelligent

Actually, they are, they know what types of numbers you're calling. This is why even for long distance prices, there is a different between calling a land line and a cellphone number. Either way, the system can tell what type of line you're connected to.
