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.

*UPDATE*
While at home downloading apps from Android Market on 3G with wcdma only selected the radio dropped with no netowkr connection. Bust.

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.
Hi all,
I realise there are many discussion threads linking to problems with maintaining connections and so on, but I'd like to ask for advice specifically about the HD2 switching from 'H/3g' down to 'G'.
Basically, I'm finding there is a fair delay between the HD2 being disconnected from a 3g network and needing to switch to 'G'. I'm in a patchy area right now, and I often look down at my phone to see it displaying 'H' or '3G' but with 0 bars. If I attempt to make a call, it sometimes seems to force it down to G, or it just hangs and I need to redial. During the time I'm on 0 bars I appear to not be contactable, i.e. no calls can be received.
Just now I made a call and the other party could barely hear me. I looked at the phone and I was on 0 bars of 3g. I had to disconnect and call back, with the HD2 then stepping down to G. Why couldn't this happen straight away as the 3g connection was struggling?
I'd like to know if there is any way I can force the HD2 to step down to G fast, or whenever there isn't 1 bar of 3g available? My Hermes was very fast at switching between the two, and I could easily hold calls on the road going through different areas with minimal dropouts.
I've been reading threads on here, someone advised changing the setting in 'Band' to another setting then back to 'Auto'. This didn't help for me.
This is probably a radio issue, but I'm on about my 4th radio now and am still struggling. On a side note, my HD2 isn't latching on to 3g and holding a steady connection anywhere near as well as my Hermes did, but I'll keep experimenting with radios. How is your HD2 comparing to other 3g devices you have?
Is there anything anyone can advise to ensure that I can actually be contacted when my phone is on and in an area with 100% 2g coverage (besides disabling 3g all together)?
Hope this makes sense.
Network: O2 UK
Location: Tunbridge Wells, South East England
Rom: HTC 1.66
Current radio (will be reflashed with something else today): 2.07.51.22_2
Thanks!
You can flash tmo radios with 1.66?!
Which ones have you tried, for reference.
Can't answer a call.
I'm on AT&T US. I have a T9193. I'm having a similar issue. The phone will not fall back to E or G while ringing or on a call. It just drops the call. By the way I show 5 bars of H and my download speeds are 500-700kbps. The phone bands are both on auto.
If I call my cell from a land line, I hear 2 rings then a fast busy. It does NOT fall back to voicemail. I can't pick the HD2 up at home at all. I wait for the caller ID then force the phone band to GSM then call the person back. It's not random at all. It is EVERY call.
If the phone is on EDGE it works fine for voice.
I have tried the 2.07.50 default radio and now I'm running the 2.10.50.
I use the SIM from my trusty x7500 as my main number and it's 2 years old. I also tried my backup number with is a SIM from last October.
I'm lost at this point and ready to back to my cracked x7500. At least I can make a phone call. That is what these things are supposed to do right?
i am on the stock radio 2.10 stock rom with alot of tweaks i have done my self ok the problem is it seems my tmobo conection is harribal indoors 1 or 2 bars edge and alway s changeing if i step outside the bars shoot all the way to full 3g will flashing the 2.11 radio help this at all or is this just what i have to deal with on tmobo network any tips or tweaks on geting better service indoors would help this seems to be any building or house not just one location PLEAS HELP!!!!

A lot of us have the same issue. I think it could be that the signal strength in certain areas is not strong enough when inside buildings.

T-Mobiles 1700mhz 3g band doesn't penetrate walls or objects as well as a lower mhz signal would like at&t's 850 band. It travels farther, though, so t-mobile doesn't need as many towers to cover an area, but that also means there is going to be more areas that have weak signals in a covered area. So, unless you're close to one of there towers, you won't get good 3g signals inside buildings.

The radio has to have something to do with it though because the 1700mhz band penetrates just fine for other HTC phones.
I have my HD2, MT3G and the G1...here at my desk at work, I can have all three side by side and the G1 has 2 bars 3G...the MT3G has 3 bars 3G...and my HD2 bounces all over the place between 3G and Edge... so you cannot tell me that they are receiving different signals.
...outside, or in 99% of other places I go I have no 3G problems with my HD2...unfortunately though, I spend a lot of time at work and would really love to have at least a steady 3G connection without having to put my SIM in a different phone.
Try changing the access point
if you go into the connections setting for the tmob data connection access point address. tmob default is epc.tmobile.com. try usin wap.voicestream.com or internet2.voicestream.com
well i guess we cant look foward for better service tell more towers go up i did have a sidekick lx that was not bad indoors could this be due to the danger server if so is there anyway to use that server instead
it kinda sux when friends from work sit next to me and can use att and verizon tv and streaming and i can not with my supper phone with bad indoor connection wish i could do something about it or some of the supper guys here at xda
Radios are ****, plain and simple. I have a g1 full bars 3g always on and my hd2 1-2 bars, 3g comes in and out. I called t-mo support and they tried the singal in your area bs. I said listen I have a G1 right next to the hd2 and that old clunker has full signal so stop there. Then they said, we are aware of the problem and are working on it.
same here
i have my g1 and HD2 side by side and the g1 has 3 bars 3g and the HD2 has only 1 bar edge and won't respond!
No complaints about the HD2's reception here. Having come from a Nexus One, I had them at the same time for about 2 weeks.
The Nexus One dropped calls constantly while inside at work, forget about keeping a reliable 3G signal, in fact I was lucky to keep EDGE indoors. If you moved the wrong way (literally!) it would bounce around in signal strength and would lose data connection constantly.
Looking at the HD2, I have 3G connection pretty much constantly, jumping into H on a regular basis. No dropped calls, sound quality from the ear speaker is phenomenal , and never a lost data connection.
Outdoors is even better.
Again, no complaints here about TMoUS's signal here!
anyone know if the 2.11 will help at all
I HATE that the HD2 will sometimes show full (phone) bars, not 3g or E, but yet not let you call. I had this happen to me for 2 minutes today. I had to go into settings and turn the phone option off/on and wait a minute for it to get a signal again. I'm in NYC, there's usually full 3G bars when outside.
This phone doesn't handle weak signals or situations when you enter and leave areas with no reception.
hmmmmmmm
i just found something iv been testing it for 30 min now if i lay my hd2 down flat on table or anything flat i can keep 3 bars 3g indoors i pick it up and hold in hand and boom 1 bar edge this is wierd wonder if this means anything im going to tryit at work tomorow see if it dose the same thing tryit see if your phone dose the same guys let me know i can stream video on mobi tv as long as its laying flat 3g i pick it up and the video stops and phone goes to edge

Yes, that's one of the crazy things with this phone. It can sit on a table all day and the 3G icon will be full bars. As soon as you touch the damn thing, you see the bars drop to 1 then it goes to Edge full bars then it drops to G...and will not go back to 3G until you put the phone down.
This needs to update fast. Thing I'm gonna go back to my TP2 until then.
I am a little confused here. some posts seem as if it might be a device issue and others seem to be leaning towards t-mobile. i had some really bad issues with my reception until i changed Radios. i am currently using 2.10.50.19._2 and my 3g signal seems to cut out less. but its is not as strong as my Tp2 which had excellent 3g signal, but i did call t-mobile and they said there have been issues reported in my area and they are working on it but if that is the case then my tp2 would also have the same issues which it does not! so i don't know what to make of it??

I think its the phone. I've never had issues with my G1. I went to the Cliq and it had bad reception. I could set it next to my friends G1 and Mytouch and they both had 2 - 3 bas of 3G and I would be on Edge. The HD2 is a little better but not as good as the G1 and MyTouch. The N1 has the exact same issues and they are both HTC. Hopefully a radio or software update will fix the issue. Its a know issue with Tmobile so they are aware of the issue.
You can try to go to settings, personal, phone, band, and change the select yout network type option to wcdma. Leave the slect your gsm/umts band option to auto. This tells it to only connect to 3g. I had to do it with my at&t windows mobile phone when I was at my job to keep it on 3g. Also with my t-mobile hd2, in certain places i have to do it otherwise it switches between 3g and edge. Downside is, if there is no 3G signal available your phone will have no signal. It should work since the phone is detecting 3g signal.
Its great to know that I am not the only person experiencing these issues with the HD2. I lay it down on my desk and it will read 3 bars 3G. Pick it up, and it drops to Edge. Never had these problems with my Xperia X1i. Something I have noticed is the battery life on my HD2 is much better than my Xperia X1i. Although it has a larger screen and smaller battery. I think the Engineers at HTC reduced the power to the Radio to help improve battery life. Anyone have any theories on how to increase the power to the radio antenna?
Just saw this thread when I was looking for a solution to this exact problem. I just recently moved to Houston and can not seem to get a T-Mobile signal inside my house with my HD2. It got signal just fine in Alabama, but nothing here.
I have a Dash 3G right next to the HD2 with 3 bars of 3G, hd2 has nothing. I even put my sim card in an old hacked iPhone and it even gets signal inside. I can't figure this out but its making me consider having to get rid of the phone. What good is it when the phone doesn't get signal?
I also just saw the new 2.11.50.20 radio on the forums, so after I charge my hd2 i'm gonna try that out and see if it helps.
I am from Houston too. ( Pearland Actually )
Same story here, inside my house NO 3G! However if I am driving around town I usually have 3 or 4 bars 3G. Let us know if that new radio ROM helps at all.

No help. 2.11.50.20 isn't doing anything, still getting 0 bars inside and 2 bars of when I go onto my front porch. Down the road I get full 3G, so I don't understand whats going on at all
I'm in an area that t-mobile maps show should have excellent phone and data coverage. Both are horrible. Data service is almost always edge with very few bars. If I ever do get 3G its usually only momentary and never above one bar.
The problem is reception doesn't seem to improve regardless of where I am. I drove to a neighboring state along freeway that t-mobile showed had full coverage. But the few times I did get a signal, I was roaming.
So, I arrive in Boulder CO thinking I should have excellent coverage, but nothing changes. Hardly any signal strength when I do have a signal. I've tried all the radios, several ROMs... even the stock one. Nothing helps.
The question is:
Does t-mobile coverage general suck? This is my first time with the company. I plan to get someone's version of the Galaxy S, but if t-mobile coverage is this bad, I'm not getting theirs.
Does the Leo radio generally suck?
Do I have a bad phone?
Is there an app that measures and logs signal strength (preferably with GPS)? I've seen them for wifi, but is there one that tracks and logs the voice/data signal on the t-mobile network?
I had a G1 before the HD2 and I usually get the same or one bar less than what I used to get with my G1 in the same places.
Try these

1: its the reception but they have REALLY good reception around the US are you surround by tress or alot of buildings/businesses?
2: i prefer the 2.10 radio it works really well
3: call t-mobile and tell them bout your problem, but before you call do a hard reset and dont install any apps, if that doesn't work Switch your sim to another phone and see what type of service you get but use a touch screen phone
i have a different problem BUT VERY ODD!
At my house i get 3g but i can't even receive calls or call out but i can text perfectly and use the internet, i switched my sim to another phone and had the same problem i get 3g but wen people call me it goes straight to Voicemail, i found 2.10 works the best for me but i live in VEGAS it still didnt fix it but it kinda made it better...

At my house i get 3g but i can't even receive calls or call out but i can text perfectly and use the internet, i switched my sim to another phone and had the same problem i get 3g but wen people call me it goes straight to Voicemail, i found 2.10 works the best for me but i live in VEGAS it still didnt fix it but it kinda made it better...

Home office in an average neighborhood. I tried to find an app that measures the GSM signal strength. I found a demo of MobileGX P3Kit and it did just what I wanted except it doesn't log the signal strength. But, I guess the company went out of business. It only worked once, and the website link is dead.
Does the data connection use a different frequency than the phone signal connection? That's about the only thing I can think of that would cause the problems you have at home. Weird stuff.
I am in a marginal coverage area and the HD2 radio is horrible. I'll go from 3 bars to no bars back to 2 bars then to none in under a minute without moving my phone.
On my Blackberry I would get usable coverage everywere in my house, none in the basement, with the HD2 its pure luck if I can use it on the front porch.
When I'm standing below a T-Mo tower I will often drop a bar of signal... and thats standing under a tower, several other people with HD2's that I have spoken with have the same experience.
Seems like it varies from phone to phone, and from location to location.
I had a Cliq and despite it being a POS, it had excellent coverage, then I got a Nexus One and its coverage would drop regularly at home. It would drop so often that I didnt really use pandora or surf the internet unless I was on WiFi.
Now I have the HD2 and its been somewhere in the middle. Lots of people say changing the radio will fix your issue. I would definitely start there. Just because a radio version works for some doesnt mean it will definitely be the best option for your location.

So, I arrive in Boulder CO thinking I should have excellent coverage, but nothing changes. Hardly any signal strength when I do have a signal. I've tried all the radios, several ROMs... even the stock one. Nothing helps.

Strange, I just left Boulder and I had full 3g signal strength.
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.

Yep E61 is on nokia's list of Class A devices:
