[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] Help? Call often stopps after 2 sec

Hi,
I have noticed that the switch between GPRS and HSDPA does not work good if i receive a call. Lately it has happend often, that phone calls only last a few seconds and then the connection fails. I normaly have medium signal strenght and the "H" in the statusbar and after the short phonecall the "G". When I call back the phonecall works fine. The ROM is Fallout and the Radio 20.48.30.0822U_3822.09.08.20_M. I'm in Germany and use the vodafone-network with 1+1.
Would a radio update help? When yes the one to 20.4801.30.0822U_3822.10.08.04 or the virtous-rom one(that update-file contains more elements are they all needed or just the radio.img?).
Has someone expirienced the same issue?
Thanks alot!

Seems like either a radio issue or a simcard problem.. Had the same disconnecting calls isuue as you and turned out that the sim itself was the culprit. Try having the sim replaced at your operator and if that doesn't work you can do a radio upgrade. I'm currently on the virtuous leaked radio and it worked wonders for me in terms of reception and battery life also so i recommend it..

Low / no GSM signal after update

Hi there,
I have updated my phone through "Wireless Update" found in the System menu and since it's been updated I have either low signal or no signal at all (depending on location). For example, at my workplace there isn't much signal strength by originally but my phone was available at 3/5 signal strength marks. Now I have Zero marks and no network, nobody can call me all day long. At home, the signal strength was 5/5 before now it's 4/5 constantly but if someone calls me it drops to 1/5 or 2/5 immediately.
My phone is a THL4000 with KitKat 4.4.2, MTK6582KK
Would you please help me how can I solve this problem?

Today I found out it's a phone issue and not the carrier.
I tried to switch my SIM with my colleagues' phones and my sim worked just fine, while I tried their SIM in my phone too and still no signal even with another carrier. I also contacted to my carrier and they made zero change to the signal strength or anything else in my area.
I also did a Factory Reset to my phone from the system menu. I'm not sure it reverts the recent system update that may cause this issue, but nothing has changed - again. No signal at all at my office. It worked just fine until last week and I made zero damage/fall/etc, only a system update.
So please, does any of you have idea what causes this or how on Earth can I fix this?
Thank you.

Phone calls does not work on oneplus one, cm 13

Hi,
I am usually a reader but on the last few month I am facing with signal problem on oneplus one, cm 13.
After a lot of searching I finally isolated the problem:
4G works fine- only data
H+ works fine when there is fully signal. Usually makes problems.
G works fine data and calls.
H- calls works only if there is fully H signal, 90% from the times if there is not full H signal phone calls are not able.
This what I tried to do:
I changed to lte/gsm, and made the default network 3G.
Notice ***: when I try to make a call the network changed from 4g to H+ or H, and after few seconds it shows call ended.
What I tried to do:
1. Factory reset - did not solve the problem.
2. Change mobile company- did not solve the problem.
3. I rooted the device and unlocked bootloader, then through twrp 2.8.3 I flashed 44s modem flashable, and it only broke my proximity sensors, then I flashed tugasensorsfix and it repair the proximity sensors. But still I can not call people!! Only on 2g but Who can live on 2g network??
I am desperate to help, I will appriciate any Kind of help.
Thank you,
Ido Levi! .
