[Q] Data Network confilict

Hi all,
i noticed that my phone (drops/do not) receive calls if i was connected to the internet through the data plan, but it works just fine if i was connected through WiFi, any ideas?
PS: i changed many radios but still the same.

When the calls fail, is the phone is on 2G mode or 3G mode?

i was having a bad reception on 3G so i switched to GSM Only option.

That could be the problem - as 2G does not allow data and voice/text at the same time, could be that because data is active, calls are being dropped. Try disabling data for a while and see if the problem goes away.

yes that is correct, when the send & receive bars of the data is blinking i cant receive calls, otherwise i can receive calls with no problems.
i will try to switch back to 3G and test how it's gonna work.
thanks for your help.

No problem. I had this problem a lot before on my HTC Legend using the stock ROM. While on 2G mode, people would tell me my phone would keep going to voicemail even though I had full reception, and sometimes I would receive texts really late. It was very annoying as I never had the problem previously on Nokia phoens.
However, since switching to CyanogenMod on the Legend, and also on the Desire S, I haven't noticed the problem as much.

Have the same problem on same carrier,
Sometimes, an SMS notifies me that someone has tried to contact me with no success !!
I thought this was carrier related, but never thought this is 3G/2G radio problem on stock ROM!!
Will give the "GSM Only" option a try and will report back.
Thank you all !!!

[Q] Hero H9500 on O2 - no 3G connection

Hi, I hope somebody can help with this.
I have just received my new Hero H9500 Android phone. I am on O2 in the UK. I can connect to their network for calls & texts - I've even been able to make a video call. Internet is only achievable via WIFI. If I switch WIFI off and enable 3G, the phone just doesn't connect. I have tried downloading some apps to manage the 3G on/off, but this has made no difference. Having just got off the phone to O2, and them telling me that because it is not a phone that they sell they cannot help me, I'm now feeling a little hacked off!
The ROM is the stock ROM supplied, which I was intending to leave on, I'd rather not switch to the Zopo p900 ROM unless it is really necessary.
So if anybody has any useful advise, I'm all ears.
Thanks in advance!
****** I have resolved this problem...apologies if I wasted anybodies time! I manually changed the APN settings that O2 had automatically sent me when my SIM first registered on theor network and with a switch off and on of 3G it suddenly connected!

Help Needed: Data Roaming Won't Run, Since update, Stock ROM, confused

My father is using Tab2 (P3100). Running Stock OS, Unrooted. 3G Data Connection from Vodafone Delhi India.
since a month or so back he found a update notice and upgraded the Stock Firmware to Latest 4.1.2 using WIFI
Not sure but might be since then, Whenever he's On Roaming, Data Connection Won't work.
Currently He's in U.P. circle it won't connect, Voda has 3G Service here, And I use it everyday at home/city wide.
Tried following:-
1). Checked APN Settings, they are correct.
2). Checked Data Roaming in Mobile Networks.
3). Tried Switching to GSM Only, and WDMA Only, WCDMA/GSM Auto Option, All options same result.
4). Checked wifi is OFF, and Data Connection IS Enabled, using Widgets or APPS but it won't turn on
5). Took out the SIM from Tab2, and Inserted In my Android Phone and 3G/2G Connects Instantly.
6). Put A different SIM which is from my Region but as its not On Roaming, Data Works fine.
7). Checked with operator they have no clue whats wrong in the TAB.
8). Requested Fresh APN Settings from Operator and saved it, But Tab2 won't connect.
Can someone shed some light if this is a BUG in current latest firmware of Tab2 or I am getting and my brain fails to finds a solution.
Any help will be appreciated, don't let me down my fellow members pleaseeeeee

No 3G on Australian Xoom after installing JB roms

Hi all,
I have just tried installing the Cyanogenmod 10.1 and Team EOS 4.0 Jellybean ROM's on my Australian Motorola Xoom on the Optus network. They both installed fine, but I could not get 3G working on either.
When I go into Search Networks it usually tries searching for a few seconds then just goes back to search or connect automatically. Sometimes it shows a list of providers, but as soon as I choose one it says registered on network but 3G still does not work. On the lock screen it says YES OPTUS as the network under the unlock button and it does show a signal in white in the top right hand corner but never gets a data connection.
Can anyone help me get 3G on my Xoom?
Thanks!

At the risk of stating the obvious have you enabled Data access under Mobile Network Settings.
Otherwise might be an APN settings problem.

[Q] Only Edge 2G signal in 3G area after installing CM11 badadroid on Samsung Wave 1

I recently installed Android 4.4.2 ( CyanogenMod CM11 badadroid 4.4 made available by @volk204 ) on my Samsung Wave 1 phone with Bada 2.0 (http://forum.xda-developers.com/showthread.php?t=2609560) . The first time I booted with Android I could get 3G signal. Once I went to an area with only 2G signal it dropped to Edge. The problem is that it never goes back to 3G in areas where I have strong 3G signal when I boot into bada. In settings I have "3G preferred" and/or use a profile with the "2G/3G" setting. When I use a profile with "only 3G", it connects perfectly.
But I don't want to have "3G only" all the time because when I go to an area with no 3G I get no signal at all. So, as a solution, I made a profile with "3G only" and whenever I want to use 3G I choose this profile. And afterwards I go back to the default profile which has "2G/3G" setting.
Anyone knows if this can be fixed?
