Random Reception problems

My Trinity has decided it's had enough of working and is doing some crazy stuff. Firstly if you have the phone in Automatic registration it never gets signal but will say G or 3G etc. At this point I cannot make or receive calls or texts. The only way I have managed to get it to work is by turning Auto to Manual and selecting the network..yet sometimes this doesnt work, it will show reception but calls and texts still dont work, Data works tho!!
The only way I can get a working phone is selecting GSM from the network type instead of Auto. Obviously it sounds like a 3G/UMTS problem with the phone, Sim works fine in other phones. Have tried reflashing ROM and Radio.
ANy Ideas

are you sure you have good 3G coverage in your area?
I would phone your operator.
I had a similar problem on Vodafone only when set to auto. The phone tries to pick up the 3G weak signal and so it's always droppin off and on.
The guy at Voda suggested that my phone was paired to a 3G base station several KM away, when it could have used the GSM station a few 100 metres away.
A plus of using GSM is battery life lasts much longer!
Of course there could be a hardware fault which would be unfortunate.

I assume that you've configured your phone to your operator and that you've tried different radio ROMS to ensure optimal "fit" between your specific PDA and network operator. If you haven't and none of sickboy555's suggestions work, maybe you should check these two alternatives out as well?
Cheers!

Well the problem initially started at random, did actually do anything, also I have tried about 4 different ROMS now and all have the same problem. I'm on
In terms of reception I have full 3G signal (4 bars according to the screen) as I am just outside the centre of the city yet nothing comes through but data. tis V strange. I may retry 3G when I'm somewhere else just in case its down to the local Cell.
I've decided to bite the bullet and just disabled 3G most of the time, if I need faster data I'll turn it on for that until I can upgrade to the TyTN 2. mmmmmm

T-mobile UK - Poor or no data connection under 3G

So i've had the HTC Desire for a week now and i'm starting to think there's either an issue with the phone or with the T-mobile (UK) network.
When the phone shows 'H' , browsing the net, downloading, or using the marketplace is a snap.
However, when this dips to 3G, either no data seems to be relayed to the phone or it does so incredibly slowly.
This means, web pages or marketplace often ask me to retry as no data connection is available.
I don't think it's a signal strength issue as i have 3bars when connecting under 3G.
Has anyone else experienced this?
*(worth noting that i got the latest OTA update pushed out today , and still have the issue)
*(Posted this in the UK tmobile forum too, to see if tmob have anything to say)

It is the Network.
Hero / G2 owners have had lot's of issues and last week I was in Europe with my Desire and I had 100% perfect connection 99% on H Speed (even on the underground!)
Came back here and 3G simply does not work anywhere near as good or actually at all!
H or G2 only it seems.
T-Mobile Customer Service feel that not having 3G is fine and acceptable as you are not paying for 3G and they are meeting their requirements of providing the ability to make calls, send text's and have net acces via 2G.

- cheers for that info. I've actually seen the issues with the G2 (hero) you mention on the Tmob forums. Can't believe so many users are being ignored.
Just disgraceful. I wish i knew this before signing up with them. I can't get H in my office, only 3G and it's useless

Is this network issue location specific, or does it affect of the UK? Presumably London or another major city shouldn't have this issue.

I live and work in central london.

Calll TM up I had a new QOS policy applied to my account and also I was told the MMS settings were affecting my speed.. I used speedtest.net app to see what speed I had no more than 300k on both 3G and HSPDA.. It is now fluctuating between 1500k and 2300k
They are still looking in to my issue thats why it keeps fluctuating..
Defo worth giving them a call

any updates ninjak?
i was VERY tempted to get T-mobile deal on this but now im not so certain...

Hmmm, my connection has been perfect no connection drops...ironic my BT line has gone fault (pretty much dead) and im using my Desire to tether internet on t-mobiles network till they come fix my landline on monday...so yeah no problems here

Where abouts in Manchester are you based? The coverage in my neck of the woods is shady to say the least.

Central......Ardwick (Apollo Theatre)

Having the same issues on T-Mobile Netherlands lately. It already started with my G2. But with the Desire I constantly need to retry... Let's hope we don't have faulty handsets...

I don't seem to have any problems downloading when I have the 3g or H symbol, but occasionally those symbols disappear altogether suggesting the mobile network option is turned off, but its not and it still shows 3/4 bars suggesting it has a signal. I had to reset my phone this afternoon so I could actually use data, bit annoying really.

^ sorry double post..

anyone in milton keynes? with first hand experience?

Can anyone confirm what actually happens when you lose connection to the net via 3G?
My browser has "hung" a few times - page will stop loading, and neither a refresh choosing a link from bookmarks will work. In fact this stops my browsing completely - even using Advance Task Killer to kill the browser doesn't solve the problem, and I have to reboot the phone.
Are these the symptoms people are seeing here, or something else? I didnt notice at the time whether I had the 3G symbok, or the H.

T-Mobile is really bad network i was stuck with them for 18 months on my G1 poor mobile internet and phone signal, once i download some app for it, which tells you with a noise when you loose your signal. omg had to uninstall the app becasue it went off so many times. Now on vodafone with my HTC Desire much better in the warrington (in middle of manchester and liverpool) area. A while back my dad said T-Mobile used to be that bad he had to go into the garden to make a call..

There seems to be something wrong with the settings IMO.
HSDPA is nowhere near as fast as it should be I don't think. There was a topic saying if you change the APN you get faster internet but I didn't try it.

Does anyone have the TMobile handset, but flashed a generic ROM?
Does this problem still exist with the generic ROM?
I want to stay with TMobile as the prices are easily better than anyone else, but NOT if this internet/data problem persists. I would rather pay the extra £100 to Vodafone over the course of 18mths to get solid data connection.
I will be rooting my phone when the method is made public/reliable etc, so want to know if this problem goes away.

Phone loses reception, restart to get it back?

Love love love my Desire. Few little problems here and there (Music Genre, Battery life etc) but the one main thing that is really bugging me is, that if I lose reception (I live in a area with lots of valleys), it will never regain reception even if I enter a town centre or City. I always have to either switch Airplane mode on then off. Or more often than not, turn the phone off completely and switch it back on, where it then finds reception straight away.
Anyone else getting this?
I'm on Vodafone and using the latest Generic Rom

I'm not sure if this is the same problem, sometimes i
have no data connection (i guess 3x since i have the phone).
I see some bars but no Edge or H (3g) sign and obviously i have not data connection ... dunno if the phone part work, will try next time.
anyway, i could get the data connection back by switching from 3g to GPRS mode and later back. You can see in the bar that for a very short time all GSM connection is gone ... i guess it's similar to switching to airplane mode ...
Maybe it's worth a try for you, maybe it's totally useless
btw: i'm living in a city, the nearest celltower is just a few meters away.

I have similar issues but I had the same issues with my ADP, not just the Desire.
Inside my University buildings I lose reception very often and the GSM connection always reestablishes itself but not the Data connection. When I reboot my phone the same thing happens. There is a good chance that the Data connection wont initialize and I have to switch to Airplane mode and back to get the Data connection. Really frustrating sometimes :/
Another very, very annoying problem I have is that sometimes it shows a data connection but it can't be used. It shows E/3G/H but whenever I start an app which uses data, it always times out.
Another problem, which is probably not fixable, is that my Phone likes to jump between E/3G/H quite a lot and every time it does do so, it seems like the app using the data connection has to reestablish the connection. This led to quite some timeouts when it was constantly jumping around.

I get poor 3G reception on my desire ( orange UK ) , have to go outside in the rain to get a better reception

vodafone have been getting worse and worse of late, I travel from surrey to london (central) every morning and was getting the same thing. I was even getting this all the time with a blackberry 9700, It is not the phone as I tried tmobile sim card in the same areas and didn't have the problem. Only 8 months to go of my contract which I will not be renewing.

I have an issue where if I use wifI at home for an evening, when I switch wifi off, the 3g data connection does not re connect. If I re boot, it connects immediately.

Assuming Vodafone uses Sim cards. I just had the same issue, here in the states with AT&T. I thought my Tilt was at fault so I borrowed a little Samsung flip phone and put my Sim in it but it did the same thing.
I had AT&T replace my Sim card and so far, 48+ hours, it hasn't happened again on my Tilt.
Might be worth a try.

I have this same problem at home (in South London) with my desire and had it with my G1 too (both on T-Mobile). I'm pretty sure it's a network issue rather than android or the phone. I constantly have 3 bars of H signal and during the daytime it's blazing fast but after around 5pm and all day at the weekends it becomes basically unusable with network timeouts more often than usable connections. I work 40 miles away down south and I get a consistently fast data connection down there with none of the time out problems.
I also tried using a t-mobile sim in a 3g dongle and had the same issues, it was great during the day and incredibly slow with loads of timeouts in the eve. It reminds me of when unmetered ISPs first came out and couldn't cope with the amount of bandwidth being used, I'm pretty sure this is a similar capacity problem in some areas.
I've been in touch with t-mobile and they are escalating it to 3rd line support so will wait and see what happens. As it's at home I can use wifi and it's not the end of the world but it some respects I wish I hadn't upgraded and switched networks instead, my gf's on O2 with the phone that is not to be named and doesn't have this problem at all.

In response to your most recent query on a different thread you had posted (now closed):
Will changing the radio help me?

Yes, by updating the Radio version this can improve things like battery life, network reception, Wi-Fi, and GPS signal strength, but this also depends on your region - it will either work better for you or could be worse. It may be worthwhile changing to Radio 4.06.00.02 for a few days and try to establish whether or not it improves your situation. If it doesn't, then just revert back to the stock Radio version.

I had a very similar problem on my Touch Diamond 2. It turned out to be a faulty aerial and had to go back to HTC for repair. Worked ok for a while after that, then it started again. An update to their latest ROM then solved it. So a hardware issue and a seperate software issue both produced the same fault for me.

[Q] 3g everythere but at home????

I have a problem with my Tmobile g2 running 2.2, it is all stock no modifications whatsoever other than handcent and fancy widget.
The problem is I can not connect to 3g or hsdpa network when I am at home. By this I mean the cell tower that provides service when I am at home. I have txt and calling capabilites but I have no data whatsoever. I have to manually switch to 2g or edge to check email or use the browser. I have called tmobile and they keep telling me that the problem is with my phone, however when I am 2 or 3 miles from my house and it goes to any other tower on the planet everything works fine.
I have searched the g2 forum here but could find no answers. I apologize in advance if this has been indeed covered or discussed to death and I have just failed to find it.
I did find the *#*#4636#*#* option and when it is on 2g I can run a ping test and it finds the server just fine, but on 3g it always fails to connect. Again this only occurs of course when I am sitting at home!
Thanks to anyone who can shed some light on this or point me in the right direction because leaving it up to tmobile has proven to be fruitless.

It might also be worth mentioning that i replaced the sim card today as well, this too had no effect on this phenomenon.....

My mom's nexus s has the same problem. Only difference is that when i walk out the door i get 3g. Once i walk back in, I get edge...... I think its might be just tmobile frequencies poor ability to pentrate walls.

Sounds like a problem with the 3G network in your area, or just a weak signal there.

I know its not the signal strength, I always have full bars at home Its something to do with the network....

Full bars on 3G or 2G ? If you have full bars on 3G then it sounds like a network problem.

I have the exact same problem, but my building is probably over 100 years old with 300 coats of lead paint on it. It depends on your building. Signals can bounce off of mirrors for example and other materials. The more material the signal has to go through, the more attenuation happens.

I have a similar problem, my G2 can't maintain a consistent connection, I will go from 4 bars of HSPA+ to 4 bars of Edge to nothing (lost connection to network) and it will jump around wildly between these three states (every few minutes). My wife's MyTouch 4G doesn't do this, my G1 did not do this, our kids (dumb) phones have consistent connections.
I know it's some interaction between my phone and the TMO network, I'd say it was a defective phone except the only place it happens is inside my house.
I wish that TMO offered a microcell.

There is no reception problem, I have had the phone working here for awhile and it always has full bars, like I said I can hop in the car and drive a couple miles and it works just fine. Tmobile finally got back to me today and said they are having their Engineers troubleshoot the tower that provides service when I am home. I hope they get this fixed soon, they said 72 hours.......

It's that anti-cellphonereception chemical they put into paint!!

Intermittent phone signal

I've had my HOX now for just over a month and i'm loving it. One thing that is slightly bugging me is that occasionally the phone signal will completely cut out giving me an 'x' where the signal strength normally is and telling me that I can only make emergency calls only.
This will correct itself within 30 seconds or so and go back to giving me a signal. This doesnt happen all the time which has made it harder for me to diagnose. Do you think it is a problem with the sim card (Orange UK network) or is it likey to be an issue with the radio software?
I never had an issue with Orange on my Desire although this is a different SIM card.
Any help or advice would be appreciated.
Thanks

I think this is a common problem I'm on Vodafone and this happens to me. I applied a fix when installing insertcoin Rom a while back and it doesn't do it as often now.

I'm glad this has been mentioned now because my One X (On Vodafone) drops connection all the time. The amount of times that I have been somewhere and needed to transfer money through the Natwest App and haven't been able to is getting annoying now. As I am not rooted I can't try any fixes but I have found by using GSM only around where I live, it won't drop signal half as much or often. I don't have a 3G mast near me so its always dropping connection switching between the two as opposed to a smooth transition.

Hi,
You are not alone. I'm on Orange UK and have seen this problem on quite a few occasions. Unfortunately, as yet I can't see any pattern to understand when it happens or what causes it.
Tim

Happens to me on 3. Sometimes I have to hard reset to get it back.

Glad that its not just me. At least I can rule out an issue with the sim.
As it seems to cover more than 1 network, could it be a radio issue that is addressed in a future firmware upgrade?

It is definitely not just you. I'm in Malaysia on the Maxis network and have this problem as well. It happens randomly - at the most it happens twice in a day.
Do you also sometimes get the message 'Preparing SIM card...' at the bottom of the screen?
I brought my phone to the HTC service centre and they offered to take it in to test the radio. I will do this when I get back from my holiday and keep you guys posted!

I do get that message at the bottom of the screen. I'd be interested to hear what the outcome is once you've had your radio tested.

Yep, it's the [email protected] radio firmware HTC has provided us with. Radio 2.05 is much better. HTC are useless with updates. I've had problems with my network connection for 2 months!

Me too.
Except I am on Tim @ Brasil.

This is nearly always down to signal.
If you're in an area that has decent 2G signal but fluctuating/low 3G signal then the phone will keep trying to connect to the 3G signal. Sometimes it'll be too weak and not be ableto connect and will stick with the 2G signal. If the 3G signal is only just strong enough to connect the phone will switch to 3G mode (dropping the 2G signal). Then it'll realise that the 3G signal is too weak to do anything with (showing an 'X' in the signal area) and drop back to your full 2G signal.
3G signal is breathable which means that if lots of people are connected to the 3G mast then it's signal area (i.e. distance from mast) is reduced. If no-one is using the 3G mast then it's area is bigger.
Perhaps your signal is breathing in and out of use where you are.
Obviously the radio can have an affect too, but with so many people using the same radio software there are going to be some it works well for and others it doesn't.
Personally, I keep my phone on 2G/GSM Only for most of the time and then switch to 3G when I want to use data. I hardly ever get problems with signal, and if I do I shrug and put it down to the coverage in the area I'm in.
P.S. Saying this, my 2G signal seems to drop in and out when I have WiFi turned on. Usually when I'm using wifi I'm not making calls anyway so it doesn't bother me...

Thanks for this useful info. How do I set my phone to 2g only so I can test this theory out ?

It seemed 'good enough' to me, but I only had 2 days with my phone on 2.05 and then my camera wouldn't work at all. So I sent the phone back for a replacement. Crazy it's still not fixed!

Which is correct, however any phone working correctly should manage to switch between 2G/3G without problems, i.e. you should not find the phone without a signal at all provided there is 2G coverage, which seems to be the case being reported here. My previous phones with 3G/2G never had a problem, and the HTC One X has been no different for me, it hasn't dropped it's signal, I'm on Vodafone in UK.

This is happening fairly regularly for me on UK T-Mobile. Seems to happen when switching between Orange and T-Mobile or T-Mobile and 3G T-Mobile. I've got a ROM that distinguishes between a 2G and 3G connection in the carrier name area.

Which, and what about it was supposed to be a fix? I'm using MaXimus 2.1.

It happens to me also. I'm on 3 in Denmark. They providing only 3G coverage in area. So far, I figured out that it's happening when I'm loosing signal completly (i.e. when I go down in concrete basement), and when I'm within coverage again, phone is unable to register on any network at all. Sometimes can help turn airplane mode on and off, or sometimes I have to turn phone off and on again.
