3G connection frequently stops/hangs

Hi Folks,
I've had my SIMfree Desire for a few days now and since the off I've been having some problems with the 3G data connection.
No matter what app I'm in, though the signal meter shows I have a very strong 3-4 bar 3G connection, after a short initial burst of HSDPA the connection seems to just stall and hangs until I restart the connection. It does this in both my work and home cell zones some 40 miles apart so it doesn't appear to be a problem with the cell zone. Sometimes it'll clear and carry on quite quickly, other times I get bored of waiting.
It drives me nuts in the browser and Market where surfing becomes neigh on impossible. In other apps (Stocks, Friendstream/Facebook, News, Android keyboard, etc.) I can usually come back later and I may or may not be lucky.
Is anyone else experiencing this?
I am on Orange so I'd be grateful if someone who's on Orange with rock solid 3G performance could post/PM me their settings so that I can check mine - though I haven't messed with them.
Could an app be causing this?
Many thanks!
___________
Update: From posts here, and the experience of a mate with a Desire on Vodaphone, it seems that many others are experiencing this problem regardless of network.
I've had all my settings checked by Orange Tech Support and though they made some changes they made absolutely no difference.
I emailed HTC about this yesterday but when I get home tonight I'll be following that up with a phone call. Can we all do the same so they actually realise it may be a problem with the phone itself?
Cheers All!

I have the same issue too with my Orange handset, thought i was in a bad area at the time but maybe not.... hmmmmm.....

I got this issue yesterday as well
I tried to browse the internet via 3G ... and it just stucked ... only the "up arrow" were lighted (traffic up) ... but no traffic down.
The icon went from 3G then H ... then 3G ...
Very frustrating ...
But after about 5 minutes ... I was able to browse internet.
I hate this.
Unlocked, unbranded, htc retail version.

I have an unlocked Desire on Voda and it only loses connection when I *try* to send a picture message.
Could someone else try test this please?

It's happening for me too. Just got this yesterday and on the Vodafone network. This is the perfect phone for me, but with this hanging / drop out 3G issue is really frustrating. Hope HTC fixes this soon or i will be stuck with a lemon

So most of the posts here confirm that it is the phone and not the network, as there is another thread with T-mobile users have issues with 3G.

I saw that thread but didn't add to it. It does appear that it isn't just T-Mobile and my phone, but something that many folks are experiencing regardless of network or area.
From what I can read of the other thread it appears that T-Mobile are accept responsibility as a network problem but as others on other networks are seeing the same issues I'm not convinced it is a network problem.

I think you could be on the mark this one, now a few operators are running the handset the issue is becoming apparant not just on T-Mobile devices.
Certainly something that HTC needs to address. T-Mobile, Orange and Voda customers all experiencing the same issue.....hmmmmm

It is definitely a problem for more Desire owners. A bit anoying if you are a hardcore mobile Internet user. And indeed, sending a picture to Facebook is already too much over 3G.

Do you guys also have problems maintaining a connection? for example today my data connection disconnected twice.. The only way to get it connected again is by enabling and disabling airplane mode.

Ive had same problem on my hero but not noticed on my Desire, both are on orange, happens loads on Hero Orange not able to explain must admit i just live with it as like the phones so much.

My problem seems to be fixed. When I started using the phone out of the box my apn setting for Vodafone Australia had been detected. What I did to make it work, was that I deleted the apns and reentered from scratch. My 3g connection seems to be more stable and consistent now.

This happens on mine also, and I've used 3 operators, in UK and Australia. It just hangs the connection, so I just have to switch connection off or go airplane mode, it will then work fine for a while.

When you have this problem ... Did you see the "3G icon" keep changing to "H" (HSDPA) then "3G" then "H" ?
That was in my situation. It looks the phone cannot maintain its data connection.
When it works, it works and fast, either on "H" or "3G".
Note that I am checking this problem on the same location, at my home And it is covered by "H" (hence sometimes it works).
Could this be a problem on signal stability of the mobile operator/provider?
I am thinking to buy a prepaid from other mobile operator and test it.
PS: I am using T-Mobile NL atm, planning to test Vodafone NL prepaid.

I'ce been browsing the web for about half an hour.Uploading, downloading stuff.
No problems with the connection whatsoever.I live in Antiparos Greece and my provider is Cosmote.
I have a sim free, unlocked, retail HTC Desire running the latest firmware and stock settings.

I've noticed this as well, when it's on 3g I can't actually browse but on g or h then it's fine! I'm on t-mobile.

Not exactly what I want to hear
I have the exact same problem with my HD2 on TMOBILE UK and am getting the Desire tomorrow BECAUSE of this.
I REALLY hope it won't be the same case, in that case it's a common thing.
HD2 AND DESIRE both have this issue.

There is/was a well acknowledged issue with the Nexus One and 3G connection (on T-mobile) - search it on Google.
There's nothing so far (that I've read) that says it is definitely the phone or the network.

I have the same problems.
Please contact the HTC support about this issue, perhaps they will release a fix for it.

HTC Desire can only connects "G" instead of "H".. a problem with device?

HTC Desire can only connects "G" instead of "H".. a problem with device?
Since the last few days, my Htc desire can only connects on GPRS aka "G" connections, can't no longer on "H" HSDPA 3G..
I thought this was the cell provider connection issue but, when I put my HTC HD2 next to it using exact same cell provider, the HD2 can still connect on "H" HSDPA..
I made sure the option of "connect thru GSM/WCDMA" is ticked, so my htc desire is set to connect not just gsm.
would this be a device problem on the Desire?
Cheers

I am seeing weird stuff with my desire as well. At first, when I got a data bundle woth Jimmobile (Belgium) I could only connect to the EDGE network. I didn't think much of it, because I thought that was a provider limitation. Then I just checked the use only WCDMA and it connected using HSDPA. I was surprised because when I switched it back to automatic, it chooses EDGE. I had this for a week or two. And now it suddenly grabs HSDPA all of a sudden and almost all the time.. I have decided to just roll with it. It doesn't make sense to me.. I doubt it will at any time.

Thanks for your input.. yes indeed.. weird..
Not sure if removing the battery and let the device off for a while then put the battery back n switch the device on will resolve the problem, but I will try that..
This weirdness, a nuisance coz Gprs is slow

Maybe take a look at this thread: http://forum.xda-developers.com/showthread.php?t=656192
You might find something useful.

My problem is that I'm almost nowhere getting any quality 3G/H signal, especially in buildings, where my old N73 got full bar 3G. I'm working on Gprs or Edge if lucky with the Desire. Very, Very disappointing to say at least. This has nothing to do with Wifi here.

Dont compare the "bars" ... they are just UI/graphics.
Check the speed and reliability.
What I noted ... when you activate mobile data (from OFF to ON), it will take some times (like 30 - 60 seconds) to connect. This may vary on different mobile operators.

My Desire can connect to H without any problem.
Perhaps wonky batch?

It can connect, when the signal is strong enough, like on the open. But thats way worse what my other Nokia 5230 can do with the same signal strength. It connects in the deepest and darkest hole.

I set it to WCDMA only. It got 3G 0-1 bar. No data transfer and some seconds later it showed a big fat X.

Data connection keeps randomly not working?

It seems random when the data connection works and the internet works on my phone. I'll sit there with full 3G signal and i get "cannot find the DNS Server" error when trying to load webpages :S
is this a problem with my Samsung Omnia 7, Windows Phone 7 or my network (Orange UK)?

I have this problem on my HD7 as well. If I have a 3G connection, it doesn't work. It only works on H (HSDPA).
Funnily enough, I had the same issue with my HD2 running WM6.5, which makes me wonder if WP7 is using the same comms drivers.

I have this problem too! A LOT everyday in diferent locations.
Actually how can I enable the HSDPA on my HD7? Because I can only get 3G.

These are just network errors.
I use internet alot and it happens on every device I had.
My WP7 is actually pretty stable in this regard.

Same! Never works on 3g only ever H you sure its just network errors cause it happens alot

YES this is a major problem for me with my Omnia 7, I even got a replacement phone from my carrier (Optus Australia) because of it... and it's exactly the same. It's extremely frustrating and makes the phone damn near unusable. Happens on every device? what a load of rubbish, if I put the SIM in my old iPhone 3GS it works FLAWLESSLY. I don't know what I'm going to do.

Can you explain then, how come a reboot always fixes the problem?

Yep, I have the same problem with my Omnia 7.
On all 3 of the networks i've used it on, T-Mobile, Virgin and GiffGaff.
Only solution is to reboot the phone.
I thing i've noticed, is it seems to happen when I move from an area where I have WiFi access (Home/Work/Cafe) to an area where i'm using a Phone network ?

I think we can only hope that the upcoming WP7 update fixes this. Also it seems enabling airplane mode then disabling it also fixes it in a similar way to rebooting the phone.

Im having the same issue with my HD7. Only EVER works on H. Not on G or 3G. It's driving me insane. The exact same sim on the same provider never had an issue on my Touch Pro 2, but this phone is shocking for internet

I get this occasionally on my HD7. Not really an issue right now. It does get annoying sometimes when the wifi in my house isnt strong enough to connect

You do realize that phones switch to H only while they are actively swapping data, then fall back to 3G while dormant, to save battery?
Try it - leave your phone alone for a bit and it will switch from H to 3G. Now access something on the net and it will switch to H (if possible) to get the data, then after a few seconds of inaction it will switch back to 3G.
So yes, it is correct that it only ever works on H!
Mind you, it would be nice if it worked on G too, I'm sure it should but mine never does.

hm i thought the " H " means that i dont get 3G signal.
but i think i had the same problem!
solution:
you only need to turn OFF WIFI
somehow its not using 3G when wifi networks are close,
even if you not connected to one.
turn OFF wifi or maybe only "discover new networks"
turning OFF wifi always brings me 3G back ...

Just to add my experience here...
I have a Samsung Omnia 7 and had never experienced any issues with 3G/H data/internet issues on the 3 network in the UK.
However, I've come over to Australia to visit the folks and have put in a Virgin SIM, now I really struggle with this. The connection just isn't working even with full 3G signal.
As pointed out, toggling my Airplane Mode works most of the time - I guess this is because the phone re-registers itself with the network when you enable>disable airplane mode (just like it would if you rebooted it). Curiously toggling the data connection option seems to have no effect.
Pain in the a*se.

I had connectivity issues with my Samsung Omnia 7. I worked out that my phone was not playing nice with my router and so my wifi connected but didn't actually work.
Also, I found that 3G performance was sub-par and many apps timed out because they were taking so long to get connection.
I solved these problems by flashing a new firmware. It was a little tricky and it is potentially risky, but a quick google will lead you to the relevant information.
I used a European firmware (I am in Australia on Optus), but it works fine. I just had to change all the language settings.
Now my phone's 3G and WiFi connections both work a lot faster (no more waiting for an eternity for the marketplace to open for example).

I have the same problem and read on create.msdn.com it has something to do with how wp7 handles the connections.
If the provider cuts off the connection frequently it loses its 3g signal or something like that. Thats why my push notifications are just unreliable. If I take my sim out and use wifi only. It just works and keeps working as soon as I connect to wifi. When 3g comes into play and the carrier cuts me off because im not actively using, the phone struggles to recconect for push etc.

Text/call problems on 3g only

Hi,
Does anyone have any ideas on a specific problem I have with the One X (on t-mobile - sim only contract in UK)
Had the phone since it first came out and the last 6 weeks I've been unable to send or receive texts while the phone is in 3g (wcdma mode or wcdma/gsm auto). The only way I can receive/send texts and calls is in gsm mode. I've been on the phone with T-Mobile for over an hour making sure my service centre number and network operator is correct and I have no signal issues (mostly full signal).
I've tried turning the wi-fi off to see if that's an issue but it makes no difference. What's weird is that in 3g (wcdma) mode I have no problems with data, so I can use the internet/facebook/twitter apps and upload/download pics and files just fine.
The engineer at T-Mobile (android dept) told me there's a 3g and 2g antenna in the phone and the 3g antenna may be faulty. Sounds plausible but wouldn't that mean no data connection on 3g too? I've also been told to check my micro sim in another phone, which I'll do when a friend comes round (I don't have any other phone that uses micro sims).
I just thought I'd check in here to see if this is a known issue. I've googled and nothing's turned up with this particular problem. Normally it isn't an issue as I use wi-fi for data so just keep the phone in gsm mode. However, when I'm out I swap to 3g sometimes and forget to swap back. I had two days worth of missed calls and texts when I forgot to switch back this weekend :laugh:
In summary:
gsm mode = texts, calls and internet all working fine (though slow data connection, obviously)
wcdma = no texts or calls but internet fast and working fine.
Any ideas, help or advice would be appreciated. I don't want T-Mobile saying it's a phone problem and HTC telling me it's the network's problem.

The same problem here using a WWE model (no carrier) in Vivo Mobile (Brasil).
No solution until know...

Mobile Data stops working

Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605

Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!

THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
