Hey guys!
I tried searching the forums on an answer to the question I'm having, but no luck. So.. without further adue, my first topic..
Is there a way to disable GPRS, and have only UMTS (and 3G, HSDPA) connections?
The reason I'm asking this, is that whenever I move into an area without UMTS coverage, it automaticly switches to GPRS. When this happens during a phone call, the call gets dropped! Also, while having a GPRS connection, noone is able to call me, without me noticing.
What I'd like to happen is that when there's no UMTS coverage, there will not be a data connection, at all, not even GPRS. (of course, GSM will be available at all times).
I've tried the utilities Bandswitch and CommMgr Pro (www.commmgrpro.com), but both do not seem to offer this feature.
Any idea's?
I am having a strange problem.
As soon as I start a call all data connections (including Wifi) are dropped.
They automatically come back after the call is ended.
Has anyone else experienced this?
Is this something that can be fixed?
Thanks in advance for all the help.
I have had this happen to me only when connected to edge. While on 3g the connection stays.

the point of 3G is that the connections will not drop.
Thanks for all the info.
I tested the Wifi again and that did work.
I don't live in a 3G market. So i guess i'll have to wait.
it only comes down to the equipment of the gsm network operator
i never loose data connection with any of my phones be it
gprs or 3g
but if the network operators central equipment dont support it
it dont matter what protocol
I actually lose 3g when in a phone call...Emails, Txt's and other stuff does not come though. On my blackberry, txt will still come through while in a call. Its wierd, I have full 3g reception and I cannot browse through 3g while in a call or recieve any txt.
Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

i have sprint as well and when someone calls you when youre running hybrid, you should not miss calls. you will get disconnected from the internet when someone is calling though

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?
Hello,
the HTC support tells me, that you can´t surf (with and without tethering) and make a phone call at the same time.
Is there a hack or patch to do this at the same time?
P.s. Somewhere i saw, that iPhone can do this with a hack.
You can do it if you're on 3G or WiFi.
If you're on GSM you can't do it.
That sounds great!
But when im on gsm in internet, does i still get incoming calls?
That is very importent for my business...
No, only on 3G. GSM supports only call or data, not both at the same time. If data is connected but not actively transferring stuff, incoming calls will go through, but if you're downloading at that moment the call will just sound busy/go to voicemail. That's a network limitation.

Actually it is not a network limitation.
There are Class A devices out there that can handle simoultaineous voice and data sessions.
GSM is not a network connection like GPRS and other. GSM is like old 56k modem which dials up a number and holds the line. Therefore, you cannot connect to GSM and make a call. This is a network limitation, not related to phone (unless you have 2 sims).
GPRS, EDGE are extensions of GSM... and today's general use of "GSM" includes those... GSM = not 3G
I have TMo tab with att sim. Done everything like flash, carrier unlock, root, modemswitch succesfully. I was just checking what happens when i am watching online stream video or surf web but i when i called from home phone tab is going to voice message, no rings on tab. But with wifi i can surf, watch videos and am able to receive calls. Any solutions?

That's because you can't!
EDGE is 2G, and on 2G you don't get simultaneous voice and data.
If you are connected via 3G, you should be able to do it.

Dave
BTW, that T-Mo Tab doesn't support AT&T 3G frequencies normally, and I don't know if it has a soft radio to allow for flashing that kind of support or if it's still a "hard" radio like most phones and devices are.

It is a hardware limitation. T-mo tab=t-mo frequencies and no rom or modem flash or settings can change that. So EDGE will be the fastest cellular speed you can get. And no simultanious data/voice.
Ok I hope someone fix that edge issue. It would have been better that i had bought AT&T tab because of voice and 3G.
...so why did you buy thr t-mo version? This part lost me.

It isn't an EDGE "issue" because it simply isn't possible under EDGE!

First of all, it IS an issue. Agreed, you can't do both data and voice while on Edge. However, what happens is that if you are surfing on Edge (data) and you receive a call, your data connection drops off and allows the voice connection to take control!
pat123 but i did roto's 2g modem update. Do you know 2g and data works together?

Still not an issue, because that is under the carriers control to decide whether or not to prioritise voice or data. If you are on a network that supports NOM1, when an incoming call is received the *network* suspends your data connection to allow your call through. If however, you are on a NOM2 network, this does not happen, and no amount of ROM flashing or tweaking is going to make the slightest difference.
The point is that unless you are on a NOM1 network, there is nothing you can do about it from your phone!

Dave
The technical term is network capability. That network is older than android.
Thanks all got it
