3g has been up and down a lot in the Glasgow area. Right now, I can connect but not actually do anything while connected to 3G (GPRS is fine). Can anyone else in this area confirm that 3G is not working? Is this a Glasgow thing or is it happening throughout the UK?

Do you mean specifically for Tmobile or any 3G network in Glasgow?
Have you spoken to Tmobile about this?
I'm down south and having problem recently at my home address.
I mean specifically T-Mobile.
I must say, I am unimpressed with T-Mobile's fast data service. Their 3G service is down most of the time and they are reluctant to enable HSDPA even when you ask them to.

Hi
I use my Vario-2 connected to a laptop daily on my commute between Stirling and Edinbugh. Some days it works brilliantly, most of the time its so-so and sometimes it wont work at all!
Its a t-mobile issue, but they wont acknowledge it or fix it. They just keep asking me to provide them with 5 reports of it not working properly incl postcodes (which I do) then I hear nothing.
One thing I find all the time is that disabling HSDPA fixes many of the issues. Basically, HSDPA does not work well when I am moving. I notice this with downloads which may run at 70KB/sec when in the station, but as soon as th train starts to move they drift away to nothing. The phone does not switch back to vanilla UMTS soon enough when HSDPA stops performing properly.
I now run with HSDPA disabled except when I am stationary.
I wish there was a way to disable HSDPA without having to soft reset the phone for the enable/disable (of HSDPA) to actually take effect.

I searched all the threads and found nothing on this as far as I can see. I have been having this since day one with my G1. Every time I receive a call on my G1 or during the call it drops from 3G to GSM. I had stock T-Mo roms on my G1 (Pre/Post Cupcake) then JF 1.51 and now cyanogen 4.0.2 and this problem persists. I called T-Mo a few times on this and they exchanged my G1 3 times and gave me a new battery and charger free of charge. Does anyone else have this issue or know of a work around? This happens when I am at home and work. I travel for work to different locations and it still happens. When my phone rings it automatically drops 3G and goes to GSM (no icon next to the radio icon in the status bar). While making calls it stays on 3G for about a few seconds before it craps out and drops to GSM. It totally skips EDGE and GPRS. T-Mo said they sent out radio antenna tech's to the antennas near my home and they said all is fine and dandy. I live In Queens NY and work in the Bronx. When I travel to Brooklyn its the same as well as driving though Manhattan. I hope someone can help me with this.

ive always had this as well .. just never considered it a bug lol ... but i could see why someone would wanna keep their 3g while on a call .. reminds me of how sidekicks would lose data connectivity due to a call

Could you elaborate?
If you've had 3 G1's and a tech says there's nothing wrong with the network then it's clearly an issues with cupcake, be it a feature or a bug...
I don't really see why you would want to keep data conectivity while in a call, (unless you're downloading something in the background..?) so it sounds like a way to save battery..

Here's a perfect example where 3G would rule when working properly.
I'm talking to my wife on my BT headset while driving home from work. I have my G1 on my dash with google maps running with traffic patterns showing. While talking I am able to talk clearly on 3G and still see where traffic is building so I can avoid it. Being stuck in rush hour in NYC sux homeless man [email protected] Whenever I do this and my 3G connection drops my call quality drops and we both hear it while we're talking and then it cuts in and out and the call drops then I dont get updates. It's a feature I would really like to have. Even when Im working and talking and downloading a new update of an app. This happens when I am at a static location as well. I know driving from cell tower to cell tower can have bad effects but it does the same when I'm just at home or any of my work locations. When 3G works properly which is rare its amazing. Its helped me get un lost and find my way many of times.
Point being when T-Mo released the 3G statement they said all users with 3G phones will expierence higher call quality from the extra bandwidth. Why would they cap or or disable it when they are promoting it? I see the the point of saving battery life but it still shouldnt be happening. 3G is made for that feature to work voice + data being accessed together.
It might just be there 3g network, imo tmobile reception is horrible. Like at my house it is so f'ed up, I can sit in my chair and have 3 bars then walk 2 feet and lose service. It does this all through my house and at my work. They said it must be something in the buildings I am in, bull**** I say because ATT never does that nor did vzw when I used them.
same thing happens with me and 3g and calls..also about the house thing, hows this one for u ill be sitting in the same spot and have good 3g reception and all of a sudden it drops to edge. I know a way around this is to set phone to 3G only but then in areas where theres non im screwed
I don't get it. My wife who had the original iPhone and then 3g and now 3gs never had this issue. She would stay on Edge and 3g depending if she waned to save batery life. My old BB 8700g would always stay on Edge never drop to GSM in my apartment. My 3G doesnt even fall to Edge it goes right to GSM. This is really annoying.
every t-mobile phone I have does this
I'm pretty sure its normal
No one knows if this is a hardware, software, or network problem. Except maybe HTC/T-Mobile/Google.
If your phone stays connected to 3G, it's all good. If it drops down to EDGE, even if for half a second, it will NOT reconnect to 3G until you hang up.

If any of those 3 know they should fix it or at the very least advertise that the calls you make are dropped to the lower bandwidth of the GSM network.
T-Mo finally got 3G for the last year don't dumb it down guys. Fix this.
Yes it is true once your phone drops beneath 3G it will not go to 3G until you hang up the call.
try running 3g only or wdma only by creating phone info shortcut on anycut .. im going to try that out and see if it ever drops .. should be a temporary fix for you atleast with the whole maps thing and such but if you ever in an edge only are your screwed

I changed it to wcdma only in phone info. Hopefully this works. Everywhere I travel to throughout NYC has 3G. Hopefully this works. Also I have noticed that when downloading anything from 3G be it the market or browser it would drop from 3G to Edge as well.

Did she use att or tmobile with the iphone? Because att has a much stronger 3g network then tmobile which could be why. I am pretty sure it is something to do with tmobiles network and not your phone, perhaps your area has to many users for it to stay on 3G. I have read about how the cell towers work and they have only so many bands for each user to access at any given time so if tmobile doesn't have enough towers or those things mounted on the towers it may be set up so you only get 3G for data usage and not calls since they don't technically require it to work.

My wife is on ATT. Isn't lower frequency better at penetrating through walls and such? (T-Mo 1700 MHz and 2100 MHz compared to ATT 1800 MHz) They haven't booted their 850 MHz antennas yet so I hear.
If that is true then why not boot me down to Edge or gprs why all the way down to gsm? I been living in the same area for 26 years. I have been with T-Mo before they even had antennas in my area and walking outside was the only way to get a signal with my phone. Now I get full reception in and out of my apartment and 3G connectivity in my apartment with a signal strength of -93dBm through out my apartment on 3G and -79 dBm on Edge.
T-Mo stated that this should not be happening. Hence the 3 phones new battery and charger and techs to the antennas. I'm starting to think its a HTC Android problem and not a T-Mo problem. Hopefully a new radio update can fix it.
I didn't even know GSM was still used in that way, I thought GPRS would be the bare minimum. How can you tell the difference? I use to only get a G icon and I looked it up and for the g1 it said that meant GPRS, what does it show for GSM? Not like any of this matters though.
I really have no idea why all this is happening to your G1 but I hope it gets resolved, good luck.
edit: on the tmobile coverage map it says edge/gprs and 3g, no gsm. does that make any difference? I checked for NYC overall not any specific boroughs.

GSM is what Edge Gprs and 3G run off of. Think of it as a progression. GSM>GPRS>EDGE>3G.
The way I know it is on GSM is to the left of the Radio icon on the home screen there is another icon that shows the network your on. 3G=3G E=EDGE G=GPRS and no icon means GSM. GSM is still being used. Most SMS and MMS messages get sent to your from through GSM while you are on a call.
is there anyway or any application that is out there that will let you browse the web and talk om the phone at the same time?
If you have GSM then you can do that without any special app. If you have CDMA then you can't do that unless you're connected via wifi.
Yup wifi and phone works really well LOL...

Just came out? AFAIK 3G on AT&T's network thats one of the benefits. I believe all 3G smartphones that had web browsing had voice capabilities at the same time... that's part of what 3G on a GSM network creates.
You can talk and surf in AT&T 3G network for sure. I am not sure if it works on T-mobile though. I would think it should, as it looks like it depends on technology and not the network itself!

So I guess AT&T is full of crap! Hmmm whats new!!!LOL
Yea you can do this only with 3G connection. Cuz you are using E to talk I would assume! And 3G for data...
this is only possible using a GSM network(at&t, t-mobile...etc) without using wifi.
3g makes no difference in this situation.Verizon & Sprint run on CDMA networks and is not possible to "talk & surf" at the same time

Well the commercial is a response commercial to Verizon's ads... so at least in this case they aren't full of crap. Verizon's 3G network is based on EV-DO Rev A. You get the speeds of a 3G GSM connection but you don't get the simul voice/data functionality.

AT&T does not support browse/talk on its Edge network. So if your phone steps down to an Edge connection you lose that ability. AFAIK Edge CAN support the functionality its just that AT&T doesn't support it.
I will check on verizon when I get a chance, but if you look in the Kaiser forum, I showed everyone there in a thread how to get this functionality b'c the carriers (US) usually strip it out to preserve bandwidth. It has to do with the RIL settings in your provisioning xml. beeen a few years, but it is there if you want to dig. Look in kaiser rom development. Also, it has to be cooked in. the provisioning registry changes will always revert back to OEM settings if not cooked in.
It is not a matter of carrier but a matter of technology. Edge and 3G are akin to narrowband and broadband for landlines. Just like you can't talk and surf the web and talk on the phone on dialup but can on DSL. It's simply a matter of bandwidth.
To explain this in a more simple matter, 3g is essentially a CDMA connection. Being that CDMA carriers use said transmission for voice, they cannot use data and voice simultaneously. However, with t-mobile and at&t, voice is transmitted over the GSM radio and a 2nd radio is present which carries the CDMA 3g technology. If said GSM device looses that 3g service and falls back to edge or gprs, the simultaneous voice and data becomes inoperable. The key part to this is that a 2nd radio transmission takes place to allow the simultaneous transmission of both services. I have often wondered, however, why other carriers like sprint and Verizon don't incorporate a 2nd radio in their devices to simultaneously connect two CDMA transmissions similar to how a TIVO/DVR box works with cable/satellite services to allow the viewing of one channel while recording another. This functionality would allow them to compete with the GSM carriers.
cdma gsm
I know that when I used to work for ATTWS (long time ago), they were freaking out about the new carriers rolling in with CDMA (some with hybrid AMPS and D-AMPS 850 mhz spectrum) because, in theory CDMA should wax TDMA's call load significantly. TDMA, at that time could only hold 3 calls per channel. So about (here comes a geeky number) every 6.67 ms the calls on the channel would switch functions. Only one could TX, one could RX, and the other was Idle.... this was all transparent to the caller of course.. CDMA rolls around with the theory that becasue it's data piggy backed on the channel, it would increase their call handling ability 10 fold. Unfortunately theory didn't work out to real work practicality b/c the new PCS CDMA carriers really had about the same call capacity as everyone else.
Now, I've always touted VZW speeds here in my market bc TMO didn't even have 3g here till like 6 months to a year ago.. .and AT&T's 3G was laugable here in Jacksonville...might as well have kept the E or G icons on the phone for as slow as things ran.... HSDPA and UMTS could put a cramp on VZWs claim to speed...as long as they can get it consistent nationwide... I'd be tempted to leave for the right data speeds.....but for now, I'm in love with my overpriced VZW plan because of the coverage, quality, and speed..... who knows what tomorrow will bring.
Sorry for the long post, but it takes a bit to explain it.. (even though most of you know it.)
Thanks,

Yes my phone shows H when I'm trying to surf and talk. I think since I have a cooked rom, it may have altered my stock internet configuration and proxy settings or something and now it doesnt work.....idunno......thats my guess. Hoping one of you guys have the answer.
Thats definitely the problem make sure proxy is off and your connections setting are going to the MEdiaNet server and that should fix it.
I got an email while on a call without wifi. I'm in dallas. Anyone else getting data and voice now?
Has been possible since the beginning of time as long as you are on 3G
I concur. ↑
Sent from my Nexus One using XDA App
Really? I've never been able to do that until recently.
Usually when I'd start a call I'd lose the 3G icon and if I received email while in call it wouldn't show up until after I hung up.
Couldn't mess with data without wifi.
Used to do this on my cliq and G1 as well...
Odd.
Also been doing both (on TMob 3G) since February...
Any gsm phone can do that, but it is impossible for cdma
Your phone may have been set to WCDMA only up until now.
chalk that up as a win for GSM and a lose for CDMA

WCDMA is 3G, it has nothing to do with CDMA
In a weak 3G signal area, the phone usually does a handover and transfers the call to the GSM network when the 3G signal falls under some threshold, and GSM doesn't support simultaneous voice and data (icon disappears while on a call)
maybe you have better 3G coverage now and your nexus doesn't need to go the GSM route
I've noticed problems with using data and voice together too. What seems to happen is that it works ok at first, but the instant you lose 3G it never comes back until the call is over, no matter how good your signal. Very frustrating when trying to use your data while on a long call.
Both AT&T and T-Mobile (as can any GSM carrier worldwide) can do voice and data at the same time as long as your phone has a "3G" connection visible while on the phone call. This has always been possible.
What you may see happen is that if you wrap your hands around the bottom of the phone during a call, the signal may drop to "E" or Edge. You can't use data and voice at the same time if your phone is on Edge.
To alleviate this, use a wired or Bluetooth headset, or hold the phone with your fingers rather than your whole palm.

Have you ever seen my problem where once the signal drops to Edge it will never go back to 3G? It doesn't seem like normal behavior to me but it seems to always happen when I need my data during the call. I've been stuck on multi-hour calls where my phone refused to go back to 3G almost from the beginning, and then the second I hang up the phone goes right back to a 3G signal with full bars again. Very frustrating!

the ATT 3G network is not setup to do handoffs from gsm back to 3g. it currently will ONLY handoff from 3G to gsm during a call, and if you are still on your call, it will not switch back until you hang up. in the future this can be enabled both ways. tmobile apparently is setup the same way for now. so you're experience is normal until they reconfigure their network.
Actually it depends on the phone hardware. It IS possible to use GPRS and voice as well if the hardware supports it, its not only something available on 3G/UMTS/WCDMA. There is a pretty even split between class A and class B phones these days, you should look up the specs of the phone you're using.
Nearly all 3G devices allow you to use data and voice together since it isnt timeslot based and so voice and data is logically split and not time divided. This means you dont need specially designed hardware to do it, just the processing power to do it.
Class A
Can be connected to GPRS service and GSM service (voice, SMS), using both at the same time.
Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded.
Class C
Are connected to either GPRS service or GSM service (voice, SMS). Must be switched manually between one or the other service.
@kam187, thanks for that. I've been with T-Mobile since they were Voicestream, about 10 years now. And I thought I was making voice and data connections with my Nokia phone years ago, before their 3G rollout.
Here is the last phone I used before going the G1 route.

I was on the Phone with Dell trying to order my new Sony Bravia TV and I was trying to use the internet so I could give the rep the proper item number. To my surprise I couldnt surf the web and do voice at the same time. I thought on GSM network this was possible. When I had Cingular a few years back this was possible. What gives? Why am I not about to do both at the same time?
That's strange. I've been on the phone and surfed the internet and/or used most of the other functions on the phone at the same time.
I've had no problems talking and surfing at the same time provided I had a 3G signal. Maybe you were in a marginal reception area and the signal wasn't solid but it does work.
I dont know why it didnt work, and it sorta pissed me off, does it have to be 3g in order to do voice and data

Was data working otherwise in that area? I've been in some areas where data doesn't work at all.
it should have been.
On edge I can't get consistant voice and data with any phone I've ever had, it is more consistant when getting a 3G signal.
You need a 3G signal to do Voice + Data as 2G (G)PRS nor 2.5G (E)DGE have enough bandwidth to support both.
