new HTC user here having a weird problem

hey guys
ok so i have the TP2 running WM 6.5 professional
ROM 1.86.401.0 (67102) WWE
ROM date 25/9/2009
radio 4.49.25.17
protocol ver. 61.44tc.25.32U
my service provider is Etisalat in the UAE
the problem that im having is that when i set the BAND to AUTO, it picked up the the 3G network...but problem is that it keep shuffling between 3G and EDGE. because of that it wont recieve calls. one fix i was told was to manually select GSM BAND. the call problem was solved because of that.
but since i have done this, i been having another porblem. after using internet to say update the weather tab, i cant make or recieve call, or send sms or anything. everytime i use internet on the TP2, i have to switch to AIRPLANE MODE and then back to PHONE its driving me nuts
anyone facing the same problem? or has a fix to this?

Switching between 3G and Edge is normal, because not everywhere you have good service.
But just to make sure:
When you set band to AUTO and you are switching between 3G and Edge, can you call someone?
I had problems with my HTC Kaiser in the UAE. Etisalat and Du told me they only can provide mobile internet to BlackBerries and IPhones...

yeah, when it is switching between 3G and Edge, i cant make calls and i cant recieve calls either. they say my cell if off while its actually on

Go into the Bands page (where you manually select the bands). Press "WCDMA" to enable 3G only. That will keep you in 3G, but if you go into a non-3G area, you won't get any signal at all.
EDGE can only handle one thing at a time. If you don't have an active data connection, you can use the phone (call, SMS). If data connection is active, you can't use the phone functions. So, if you're on a webpage and someone calls you, their call won't go through.
3G allows you to use phone functions and data at the same time. So if you're on a web page and someone calls you, you can answer it.

ok that was surprisingly simple.. thanks

Edge can only handle one thing at a time? I routinely get and make calls and browse at the same time (or get emails via active outlook push connections, etc). And this is both when I'm in Edge areas (eg when I go to my cabin in Montana (heck - ANYWHERE west of Milwaukee) or when I have 3G (around here).
This does, however, appear to be a feature strictly of AT&T. But I don't believe the inability to do simultaneous data and call is a hardware or even Edge technology limitation - I believe its a network specific limitation.
Having said that, my money would be on an incorrect radio or DLL hanging around in the phone...
(Standard disclaimer: I know nothing about non-US carriers or their oddities. I reserve the right to be wrong- a right I exercise somewhat frequently )

well i upgraded to WM6.5 so the radio is the one that came with the upgrade.nothing else has been changed.
have a feeling the problem is with the phone as my pervious phone, sony ericsson's P990i had absolutely no porblems switching from data to call and back to data without having to do anything.
one thing i noted is that once i start an internet session, it keeps running unless i turn the switch to airplane mode to force a connection break.

Simultaneous call and data

Just started using my Desire last night! Feeling good.
However...
Was just on a call, tried to use the Android Marketplace. Couldn't.
Got curious, and tried to use Google Maps mid call. Couldn't.
Tried to use the internet during the call. Couldn't.
Now, I'm on T-Mobile (UK) and have just come from a Nokia E71. With my E71 I could make a call and use Google Maps.
Am I missing something or is this bit of multitasking somehow not possible???
Please tell me I'm missing something!

A lot of carriers don't currently support simultaneous data and voice. For example, I have Sprint and it has no support for this - very annoying.
AT&T is the only one I'm personally aware that supports both talking and using data at the same time.
If it doesn't work for you, you're out of luck with your carrier.

Sprint is a CDMA network, and most CDMA networks don't currently support simultaneous voice and data.
Most GSM networks do support this when you have a 3G connection. The voice call is routed over 2G and the data over 3G. If your data connection drops down to GPRS or EDGE, you will lose data connectivity because most networks do not support simultaneous voice and data over 2G, though I'm told that they can be set up to do so, so I guess it's more down to bandwidth.
Regards,
Dave

I know that Sprint's CDMA has an issue with simultaneous data and voice. Which suck. And I know they are making good attempts to sort this out for the EVO, which is good.
But again, I've been doing this fine on my E71. The only thing I can think of, in relation to Dave's comments, is that for some reason, because the Desire can suck up more data, T-mobile have restricted it. Which would suprise me because, as Dave said, simultaneous voice and data is a feature of most GSM networks and has been for a while.

I have just tested that and it's true - the phone doesn't have simultaneous data and voice connection
Now normally I don't need that because if I talk, I talk and not browse the web, but even my freaking G1 could do both things at the same time. What the heck? It must be something HTC did.
One more reason to eagerly wait for root...

I don't see how this is a big deal. Why would you need to make a call AND browse the market place or look at maps etc? Surely it's something that can be done after the call even if it is receiving directions or whatever.

It's a big deal because:
1. HTC (or T-Mobile) has obviously done something to disable it because Android with GSM should have such functionality;
2. Older Android phones and even some "dumbphones" have that functionality
3. No point in browsing market while talking, but what about looking up maps while talking? - That was even one of G1's selling points.

I have often been on a call and used the internet or searched Maps. So it's something that I am quite used to doing.
Though I thought I'd get an answer straight from the horses mouth and have emailed HTC support just now. I'm hoping they give me good news...

False alarm. This only happens on GPRS, which is normal. Simultaneous data and voice connection can only happen on 3G as explained in Android Forums.

and of course correctly explained by Dave in post #3 here.

Kind of tired of explaining this one but here are the 2 use cases:
- you're talking with someone on the phone and they ask you for directions, look something up on the internet, see if you received their email, etc, etc
- and even more importantly, when my rooted phone acts as a WiFi access point with android-wifi-tether and someone calls me, my freaking Inet disappears until I'm off the phone. This is the more annoying of the 2 use cases.

Well, this was their reply:
"If you start the call being connected through 2G, then yes the internet will then work. But as soon as the signal goes over to 3G then the internet connection and usuage will be turned off.
When it comes to wifi, if you are in a call and you are connected to wifi, then you should be able to surf.
Hope this answers your questions.
Thank you for contacting HTC. "
I did get concerned for a second. I've just tried the wifi and call which worked. And I just tried a call again, with wifi turned off and it worked, even though it didn't work before.
I just hope it routes voice and data in a way that doesn't trip me up in the future. I.e. voice over 2G if I'm trying to access data.
So yes, false alarm.
And funnily enough I just now got a call from Carphonewarehouse asking me if I'm having a problem sending texts as some Desires do indeed have a software fault where they have no Service Centre number for messages. For once, I've skipped the faulty units!
Cheers guys. Sorry scare anyone.

lol.
Whoever it was at HTC got their 2G and 3G mixed up.
what they meant to say was if it goes down to 2G then it'll stop.
You'll be ok in general, as long as you have 3G signal wherever you are. If you've only got 2G, you'll have to hang up, find out and then call back!
the SMSC shouldn't be a problem though, just program it in manually. Not worth sending a phone back for unless it fails then as well.

Even if I'm on 3G/HSPA, when I call someone, as soon as the call is connected, my data connection disappears (only shows bars, no G, 3G, or H) and I can't browse the web or use maps while in-call :-/

ok, well that's not right. The bars should only disappear if you turn the mobile data off. it should not get turned off by a call. Even if i try it when in G, the bars stay showing, just no data comes till i hang up the call.
If the bars are disappearing, something else is going on.
It could be a local network issue. maybe it's an old transmitter that missed an update or something...?could possibly be a full tower.
I know that a few years ago, the towers would kick off data connections to allow more airtime for voice calls which have priority, but i don't know if that's still relevant on 3G.

This was a hot discussion back when the Hero came out as well.
In the end I think it comes down to the network of your carrier. Some people report they can internet and call at the same time. Others say when they are internetting on their phone, a call is directly forwarded to their voicemail etc.
I'm afraid it's a combination between how your carrier configures their network and on what connection you are on (3g, 2g etc).

Yeah it's false alarm no #2 -- must be a spotty 3G at my house. I went to the city centre and tried it there -- worked like a charm.
Though it's a bit weird as 3G speed is not bad at all at my house, but when I call, data connection goes off :-/

Maybe at the city center you got more cells in range than in your house. Means your carrier got more available bandwith

I think reception gets spotty. Sometimes voice and data works, sometimes it doesn't. At home in my bedroom I can get H connection, 20 meters away I can't.
I think the important thing is that the phone is capable. The rest is just pinning down exactly the situation that we want to avoid.

[Q] Can't receive calls while on 2g

Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?

It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?

Voicecalls not coming through whenever data is on

Guys
Noticed something funny with my Galaxy Nexus. Calls don't seem to be coming through whenever it is transmitting or receiving data on the 3G. I can still make calls no problem.
My previous phone (the N97) would disengage packet connection (a warning comes up) before the call comes through.
I'm still analysis the data but I am hoping that one of you has experience this before and can offer some insight.
I've done the following test:
1. Wifi and 3G on. Some calls come through, some goes to voicemail.
2. Wifi and 3G on - streaming a video from my NAS box - Some calls come through, some goes to voicemail.
3.Disengaged Wifi and 3G on - Some calls come through, some goes to voicemail.
4.Disengaged Wifi and 3G off (2G only) - Calls comes through fine (when I send text I get the volume bug).
5.Disengaged Wifi and Data on but only on 2G - Calls comes through fine.
In all above instances when the 3G/data is on, I make sure I am transmitting (I synch my hotmail account).
So is this normal (this is my first android phone)? Am I the only one or are there others?
Any feedback would be appreciated.
Thanks
***** Sorry for the question mark icon, I put [Q] down but didn't know by selecting the question mark, it overrides it************

Which network?

It's certainly not normal behaviour in Gingerbread and earlier at least (still waiting for my GN to be delivered). Even on 3G calls should be able to come through and then if needed decide to switch down to 2G if it decides it's needed.
Have you confirmed that you can actually make and receive call on 3G currently? Might be something wrong with your plan or your SIM.

I'm still testing but it does appear that whenever it's transmitting on 3G (3G or H in the icon) incoming calls go to voicemail.
I just did another test, in the previous tests I was just calling my voicemail service (901) but I decided to call my house phone and here's the strangest thing.
- With the wifi on and 3G I couldn't make any phone calls (apart from the voicemail), the calls just end. I turned off the wifi, tried making a call it works. Then turned on the wifi on again and I can make calls again. How bizarre.
I'm hoping it's a network issue but I won't know until say about a weeks time (if its a network issue it should have been fix within that period). But my first adventure with Android isn't going very well.

Rang O2 and it sounds like an issue with the network . According to them 3G was affect all over the country recently and still have issues in the London area.
I also put my sim back into my N97 and after numerous attempts was able to replicate the fault So happy.
But the customer support suggested that I should still go and get a replacement sim from the shops tomorrow since mine is quite old. From 2009 but still 3G enabled.
So fingers crossed that its def a network issue and not a fluke that it affected my N97.

How will a new SIM be able to work better? I thought, as long as it has 3G, it's all good?
My SIM is from 2008, I guess, so quite "old", as well...

Does SIM age really matter? I've been using the same SIM card since 2005.

I don't know if the age of the SIM matters, but what I do know is after I replaced my old SIM (AT&T) my data got faster (a few phones ago).
It never hurts to use a new SIM. The manufacturers change every few years (gemalto, etc) and I'd bet that newer is better...

No internet when I'm on voice call

Hi folk, so I've something strange: when I'm on voice call (make or receive) my network change from 4G to H/H+ and internet doesn't work. When call finishes, network go back to 4G and I'm able again to surf internet.
I called my mobile company, Vodafone IT and they told me it's a phone problem (they don't use VoIP) so I contacted Google assistance but since my phone is magisked they can't help me.
Any idea?

This is a normal behavior and has nothing to do with your phone or Magisk: If your carrier does not support VoIP, the phone has to switch to 3G or even 2G to make the phone call. After the call has ended, it switches back to LTE.
I know that this can be a PITA, especially when you are supposed to take part in a Skype or Webex meeting with screen sharing and you are sitting in a hotel with bad WIFI. Then you use the phone as WIFI hotspot. As soon as you call in, your web meeting is unreliable.
Been there, done that. There is no way around this, the only thing which works for me is to take part in the call via my notebook instead of calling in via the phone. Then LTE stays - as long as nobody calls you

@BabelHuber thank you for your answer.
But why this happens?
Why isn't possible to have call and 4G/LTE at same time?

Because the LTE standard simply does not support voice calls.
Hence if you don't have VoIP, the phone has to switch to 2G or 3G. The alternative would be not being able to perform voice calls at all!
