I was thinking of posting this in the general section but posting it here seemed more appropriate as I think the issue at hand is of a more technical nature. If this is not the case I apologize in advance.
I recently purchased a Black HTC Magic (Rogers branding) for use on the AT&T network here in the states. Since then I have had a very difficult time initiating calls while connected via 3G (UMTS/HSDPA). Even in high or low signal situations.
Unfortunately there doesn't seem to be any consistency to my ability to make a call while on 3G. At times 5/5 calls would be successful and other times 1/5 calls are successful (the latter being true more often than not).
Suspecting there was some issue with my device being on 3G I forced my device to use 2G (EDGE) connections only. At which point my reliability issues go away completely (from what I can tell).
I don't experience any strange issues with using my data connection while on 3G/2G so it seems to be specific to voice.
Another interesting thing to note is while trying to initiate a call with the Google Voice application on 3G, I experience the same call initiation issues as mentioned above. Google Voice works as expected while on 2G.
I experience these issues on the original shipping Roger's ROM, as well as all the other 3rd party ROMS (HoFo, Cyanogen, etc...)
Here is information about my device from fastboot...

Is it possible that my SIM card may be causing issues?
Anyone else with a North American Magic experiencing issues on AT&T? I appreciate any help you guys could provide.
your phone is ok
perhaps you might have heard... iphone great phone...AT&T absolute **** network
with dropped calls, and constant diverts to voice mail. dont sweat it. its AT&T not
your mobile.
I would have to agree that it's probably the network, although I might be wrong. I also have a Rogers Magic running on AT&T in Arizona, and I have this issue as well, but not nearly as frequently as you do. This same problem used to happen from time to time with my HTC Fuze and my BlackBerry Curve.
I've had a variety of different devices on the AT&T network (Northeast/Washington, D.C) and although yes I have experienced AT&T's wonderful network. What I'm experiencing just doesn't seem right. Makes me wonder if it's my SIM or particular build....

Moved into general discussion forum as not related to android development
if you are not using a newer sim card i would start by changing that. i was using an older 3g sim which i have used with many phones and i found that by changing to a brand new sim the few connectivity issues i had have gone away
which ROM?
Just a question, but which ROM is everyone here using? I, too, experience the random inability to make phone calls over HSDPA. I was told by an at&t rep in-store today that the Rogers Magic does not 'show up' in their system as 3g capable. Pure bs is what I think, but lets rule out software, yes?
If it is not your sim card then it is most likely your network.
Calls over 3G/HSDPA is fine on my Magic and was also fine on my Nokia N79 using the same Cingular SIM card that I have. However, making outgoing Google Voice calls over 3G/HSDPA is a no go.
Yeah...making calls was fine on my Unlocked Touch Diamond, too...but it's NOT on the Magic (32a).
SO...I'd just have to guess that it's *probably* not the SIM card.
I was told (via an exceptionally helpful phone rep) that the "voice 3g" in my area is not very good, but that the "data 3g" is much better. Which (she says) is why I have trouble making phone calls, but that data works fine.
I don't think so...but without *that* answer, I'm left with the AT&T stock "well, we don't support *unlocked* phones, sir, we can't guarantee that they'll work with our network".
ARRRRRGH! REALLY?! SO, phones with the same chipset, using the same technology won't have the same results?
PLEASE, FCC, INVESTIGATE THIS B.S!
Hey radikaled, I have some new developments with GV and outgoing calls. If I set the GV call options to "ask for each call" the issue of calling over 3G appears to be alleviated somewhat. Basically, when initiating a call, you will be prompted on whether you'd like to make the call via GV or not. At this point, wait a few seconds at this prompt and then choose GV. So far the call has successfully connected 100% of the time.
It appears that the data connection is too slow to establish fully over 3G, therefore, the call fails if you don't wait the few seconds before choosing to call via GV.
Let me know if this works for you.
I too had issues with my ROgers Magic unlocked on ATT. When I first got it I used the original ROM and then the HoFo ROM. Both had similar issues with dropping calls when switching from EDGE to 3G and back. I also dropped more calls than normal.
I recently switched to Cyanogens ROM and new radio. I have not had any issues since and then. Calls and switching is very stable. Also the clarity and volume is also much better. Just my experience. Very pleased with this phone on ATT now.

Thanks for sharing your experience. May give CM ROM a shot.
Good read.
Nice post. Interesting topic.
I tried to send several other users your way...I'm sure they eventually checked this out. I've come across this issue with some other folks recently too.
Best of luck though.
Me TOO!
I also have a similar problem. When connected with HSDPA, about one third of the calls I make fail immediately, even with full signal strength. I then wait a few seconds and dial again, and it works. I actually am using the sim card from a previous nokia POS phone I had from two years ago; the ATT people just took it out of the previous crap phone and put it into my poor fuze. How much does a new SIM card cost? Can I get a new SIM card without att bothering me about not having the stock rom? I'm using Da_G's clean fuze 23008 winmo 6.5 with the 1.12.25.19 radio. I live in the Youngstown, Ohio area (between cleveland and pittsburgh), so cell reception on any network is pretty bad, but it seems the ATT/cingular network around here is particularily bad. Any ideas?
So I am using my N1 on att so therefor it only works on EDGE. The problem is that whenever I have an active data session open, my phone does not ring and calls just go to vmail. Is there any way to set the phone to take the call and suspend the data connection?
No one has an answer? Not even through rooting the phone can I get it to accept calls over data...
i haven't used my N1 on the ATT network, but i've never head of data overriding voice. on any network. Voice should kick your data connection. I wonder if you have an issue with an APN setting.
I'm looking for the same,
IM in the Netherlands on vodafone. 3g works fine, but can't call and use internet on the same time.
Dont you need to be on at least 3g to have voice and data at the same time?
this has always been my experience on quite a few phones I have had when in an EDGE only area and tethering on O2 in the UK, phone does not ring.
On 3G it does, in fact last night while on a conference call on speakerphone I decided to run the speed test app to see how much a voice connection impacted data and I got 300-400kbps and I normally get 1-2Mbps, only ran it once and forgot to run it again after the call has ended, so it could just be local conditions....
You are correct that you cannot have voice and data working at the same time unless you have 3g (HSDPA). If you only have and EDGE connection, you can use data or voice, not at the same time though.
So I called HTC directly and asked what the heck was going on and if there is a way to change this and they told me there was NOT. The device is set up to accept data over voice. So basically the sell it as an "unlocked" device but the functionality is is majorly flawed if it cant run on 3g. I am a little angry at this point, yes I should have researched a little more, but who the hell sells a cell PHONE where data overides voice

Apparently HTC does, probably based on usage stats. I use several gigabytes of data and 1500 text msgs per month on my plan b/w myself and my wife and we only use 200 - 400 minutes. I am pretty sure that we are not the exception either...

I understand what you are saying and I am the same way. But being such a heavy user I do often get calls when I am on the web. So it is crap that this device is really not a fully functioning phone on EDGE.
Asking your phone to put voice over data as priority on edge is like asking your phone company to put your mom's phone number over others and having her call kick someone else's call off while you are talking.
This is not an issue with the Nexus One, all phones, when on EDGE, behave this way. This is just the way EDGE works, this is why they push 3G devices and network services and not EDGE. It's old and not as functional.
If you are not happy with the Nexus One because of this, I would suggest selling it and waiting for AT&T to get their device that will compete with this.

That is not true. Blackberry curve for instance runs on edge, if a call comes it it will interupt the data connect to take the call. You cant do voice and data at the same time, i agree with that. I have had other devices like the G1 when it first came out and when it ran on edge and I was getting a call while on the internet it would suspend my data and take the call...
And I like the N1 that is why I still have it. It just sucks that on a PHONE, data is prioritized over voice. I was looking for a solution for this situation by either rooting or figuring something out within the phone, but I guess there is not a way to fix this.

You are mistaken. I've had at least 10 phones that ran edge for data and none of them could interrupt data for voice. You are probably using more data intensive Apps or webpages compared to the blackberry, so its more likely you are missing calls.
Go use the blackberry to download a 7 MB file and see if you can call it.
where i live i'm just outside the 3G areas
my past phones have been HTC and i just end up with a voicemail notification when someone calls and my phones were ALWAYS on data, people used to get pissed thinking i was avoiding them.
google voice fixes this, i can just switch to my notification, listen to voicemail or if i'm lucky read the transcription (usually doesnt match though ) without having to effect what i was doing.
On my winmo phones, if i tried to do this, i would sometimes go back to my browser to find it decided to close while i was on the call to listen to my voicemail and then i would lose what i was doing and have to start all over anyways. so this is just another reason i love the nexus one and google voice, you say useless data>voice, i say a fix to my problem. i love you n1! lol
I can not speak to blackberry phones but this behavior has been the norm for all of my smartphones, to include the G1. If I make heavy use of Edge in a non 3g area then phone calls would not get through. It is annoying but not a problem specific to the N1.
The other day one of my friends told me that when he rings my phone lately (since I've started using Android) it always diverts to my voicemail. I did a bit of testing, and figured out that is seems to be happening when 2G/3G data connection is active. Has anyone else had this problem, and can a few people test this out?
I've tested this with 2 radios:
Leo_RADIO_2.12.50.02_2
Leo_RADIO_2.07.51.22_2
and 2 android builds:
30.08.2010¦ ?shubCRAFT 1.5?CM6 Final?¦ ?Kernel: ElBartoME 2.6.32.9 #1? ¦
New Nexus One Android 2.2 Build FRG33 [ mccm v1](5.9.2010)
I have tested on WM and this problem isn't happening there. I am on O2 UK Post Pay.
I have this problem and it happens when my phone is sending/receiving data, not when the data connection is idle. It happens on WM, Android, and on my iPhone too. My provider says this is normal and nothing can be done.
Sent from my HTC HD2 using XDA App
Switching from 2.12 radio to 2.10 in my sig helped this a lot.
Sent from my HD2 mattc froyosense using XDA App
I gave 2.10 a go, but it seemed to make little difference for me.
I had the same problem with the 2.12 radio. I wouldn't get any calls from sprint users.
This is normal with GPRS aka 2G. It's like you go online with a modem and a phone line in the old days (dial-up). Even when you are trying to send a txt, and a call come in at the same time, the text sending will fail. This is very annoying.
not sure about 3G tho, some say that the 3G can handle data and calls at the same time.
I get this too, Plus when i recieve a call i cannot hear the caller for 10 seconds or so ? but the caller can hear me straight away ?
I did post this in the HD2 general thread but got no responce...
Have changed sim card as i was told this could be the issue but no luck also tried various radios/Builds inc android again with no luck..
Looks like were gonna have to live with it

GPRS/Edge does not necessarily allow simultaneous voice
Well I had no idea. I thought that one of the main advantages of GRPS/Edge was simultaneous voice and data, but I guess not. Apparently it is dependent one the cellular network configuration/capacity.
Here's an MSDN article related to it (not that I consider MS a reliable source of anything, but worth a read )
http://msdn.microsoft.com/en-us/library/bb416348.aspx
I had this exact problem. For me it started after using android on my HD2 then whenever i had my phone on UMTS i could call it with another phone and 4 times oout of 5 i would ring all the way to voicemail and never notify me. I first thought it was ATT but i tested my sibling's phone and it was fine, i even switched SIM cards. the problem seems to have gone away with my HD2 after two weeks however I ended up ordering a telus desire with ATT bands. Although now my HD2 reboots in android randomly whenever using UMTS data.

This is what I get as well, except the caller doesn’t hear me for 5 secs or so. I end having to say “hello” 3 times before they can actually hear anything and by that time they usually hang up. I’ve had this problem with WinMo as well, using Telstra on Rogers. It’s kind of annoying since I end up having to use daytime minutes to call them right back.
I found that some x.51.xx radios helped but Android as far as I know is only compatible with x.50.xx radios. So hopefully a new radio will help with this though I’m not really counting on it.
I thought I was going mad
I have the same problem but only just found out. I use my Google navigation a lot, but just discovered when I do that incoming calls are routed to voicemail. I have tried 3 different Radio's from the recommended Leo_RADIO_2.15.50.14 down to 12 and even 08 nothing seems to work.
I have also tried different ROM's from HD Desire to Gingerbread, again no difference.
Not sure if the problem existed on the SD ROM's but it is sertantly an issue on the NAND ROM's.
I am using RMNET as this is the only one that seems stable on O2 in the UK.
This problem is driving me crazy.
Someone else please HELP!!!!
Hi guys,
First of all, I'm a GSM user running the latest OTA stock ROM and Baseband.
So I've been making more calls lately, and I keep getting complaints from people saying my voice is unclear and breaking up on them. I decided to do some experimenting, and have come to the conclusion that it is not my SIM, phone's mic, ROM, or the other person's problem.
I've noticed, when calling from my Razr M to another phone (let's call it Phone2), if I set Phone2 to mute, then my voice is heard perfectly fine on Phone2. If it's not muted, then Phone2 can barely hear what I am saying from my Razr M. The whole time, anything the person says into Phone2 is heard crystal-clear on my Razr M
I know it's not my SIM card is because I just went to the AT&T store today and replaced it
I know it's not the mic is because if I use GrooVe IP to place the call via VoIP, everything is heard fine on both ends
I know it's not the other person is because I've had at least 4 different people tell me they can barely hear me on their phones, and I've tested it myself by calling the other phones in my AT&T family plan, and my landline, and the issue still occurs.
I found that changing
Code:
persist.audio.mic=digital
to "analog" instead, helps a little because it makes the voice louder, but it doesn't help with the audio breaking up.
Reverting back to the older baseband (the one that is included in Matt's Utility 1.20) doesn't make a difference.
Does anyone else have similar experiences? Ideas for me to try? I'm especially curious to hear from other GSM users.
Have been using this phone for about 1 year and 2 months now. Used a multitude of ROMs as well. Disregarding the different battery lives and heating issues, some problems remain consistently.
When on call, be it a WhatsApp audio call or regular cellular one, after talking for a while I start having network issues.
1. I can hear the person but the other can't
2. I can't hear the person but the other can hear me
3. Audio breaks up between us
4. There is no audio
This only happens in long calls, say over 7 or 8 minutes. Also, doesn't happen always but majority of times. Problem persists in both device mic and headphone mic.
Sometimes others tell me they get my number unreachable or engaged, but in that time I have full bars of network and am not in another call.
It happens with all network providers I've tried, namely Airtel, Vodafone, Aircel, Reliance Jio. And I am almost always on Wi-Fi, so I don't think there is any issue of data messing up calling. And also I always have full bars.
Went to the service centre a few months back as well, they did something after which the call quality did improve, but other problems are still there.
Any ideas on what my problems could be and should I go to the service centre again and pay or get it checked out by a local repair shop??
All ideas are welcome.
Thank you.
