[q] make/receive call work only in gsm mode? - Galaxy S II Q&A, Help & Troubleshooting

I'm facing this problem since i bought this phone.
When i set my phone to WCDMA/GSM OR WDMA ONLY mode my phone drop randomly calls and in 80% of case unable to make call ("conditional call forwarding active" repetedly appearing till call is ended).
When i switch to GSM only mode the phone run smoothly without any problem..
P.s : i thought it was related to the 3G/H issue but i don'T know exactly caus' even when i'm connected on Wifi it's the same problem.
Your Help will be very appreciable.
Regards,

please any help .. anyones facing this issue .....please help!!!!

F-f-f-f-factory Reset!
You get it on a plan or something? Or outright?

I'm afraid does'nt work for me!!!

I would guess its to do with you having a weak 3g signal and you will be connected to 3g when you make a call, then move into an area that's gsm only and the call will therefore have to drop as the signal changes.
I have a widget that goes to the mobile networks settings page and tend to keep my phone on gsm only while I'm not using the internet or on wifi etc then switch up as need be.

[Q] LG P500 network/call problem

Hello,
My LG Optimus One P500 (on Vodafone Portugal), cannot make or receive calls, neither receive SMS... Everything else works normally...
At first I couldn't receive calls only in GSM mode, and with 3G (Dual mode) was OK. Now I cannot also receive them in 3G Mode! I cannot see anything that could've triggered this behaviour... The only clue that I can come up with was installing Google Voice, but I already reset it to factory settings, and no luck!
I switched the SIM card to other phone and it works fine, GSM and 3G...
Anyone with this problem and found a solution?
Thanks!
it seems that you have an hardware problem..do an hard reset (power on+volume down+home key) if that doesn't work,just take your phone to the warranty.
The volume in incoming calls is progressively increasing...cant we change that?

Hi Utkarsh it will will great if you can share hoe you solved it, if you have solved it.
Regards,
Pradeep.
Guys how you solve it?? i am facing the same problem here.. 2g is down and only 3g is workink.. i think it has to do with the provider. when i go to other areas 2g is working great.. i am testing it an i will come up if i found any solution..
Just to inform you, that my O1 was perfect. The service provider had a problem in my area.. i spoke with them and the problem is fixed.. i think it was something with the antennas or with the signal. but anyway there is no problem..
The only thing that i can not undestand is why my O1 wasnt working and other phones (not smartphones) with the same provider in the same area was working..

Network Issue - When called to my number it says switched off!

Guys, I have a strange issue, 3 hours of IDLE time on my phone and when you call my number from other phones, it says it is Switched off!!! The network signal is full, strangely if i callback someone it rings, and then if you call me back, my phone rings normally!
I do not know what the issue might be here, I have tried resetting the phone, reinserting the SIM card. Changing the Networking setting to only GSM, but nothing helps!
This is not good, and it is causing me lot of headache, as I am missing important Client calls anyone with a remedy?
Guys .... anyone who can help me out here ?

Sounds like a network issue. Make sure you don't set the network mode to automatic/auto connect. Other than that, I can't think of much.
Edit.
Check your edge preferences and turn off any of the flip to mute functions. Also double check call rejection in Phone to see if it's rejecting calls for some reason.

Mate 10 tethering doesnt work while on active call

Anyone else face this issue? if you tether the phone internet to your laptop, it works as expected but once you make/receive a call, the internet on the laptop will stop working. I also note that the phone signal will drop from 4G to 3G/H+ on the phone once you make/receive a call.
I have tried to reach out to Huawei for support but not getting any resolution from them.
Issue can be reproduce as below:
1. Tether your phone to your laptop and check that internet is available on your laptop.
2. Have someone call your phone or make an outgoing call, you will notice your mobile signal drop from 4G to 3G/H+. Keep the call ongoing and dont hang up.
3. Check your laptop to confirm that internet has stop working.
Not surprising at all, it's by design and not linked to the fact you're tethering the smartphone's data connection.
Without tethering, use a hands free kit or earphones, make a call or simply call your voicemail and now on the smartphone try browsing or any connected app, they'll fail: data connection is lost during voice call.
In order to keep your (4G) data connection, your mobile provider has to support VoLTE and you must activate related option on your phone. I did it, it's working, didn't try calling while tethering but I'm quite sure it's the same case =)
Still no internet with either VoLTE on and off. And I dont think this is to be expected as my previous phone, Xiaomi Mi Max has no issue and can do both call and tethering at the same time. And my colleague just did a test with his new Samsung Note9 and also didnt face this issue. Not sure if this is a software bug or a hardware design flaw/limitation
I use tethering/hotspot every few days and didn't notice any problem. Signal drops from 4G to 3G because Mate 10 doesn't support VoLTE but internet works fine for me.

Please test tethering while on call, not just tethering alone. Tethering alone works fine for me as well.
Internet will pause during phone call unless your network is VoLTE. My phone network signal will change from 4G to H+ during phone call.

As I said, it works fine while on call. I use tethering in my second apartment, airports and in almost every caffe bar and didn't notice any network problems on my notebook if someone calls me. There is one lost packet when phone starts ringing and that's it.
The first photo is WiFi hotspot + phone call and the second photo is USB tethering + phone call.
Hi Guys,
Thanks for the input on VoLTE, base on this info, i query my telco (Starhub) regarding this, and just a few mins ago i received an SMS that "HD Voice Plus" had been activated for my number. HD voice plus is just what they call VoLTE. Now i have a VoLTE icon on the top left of my phone. I tried the same case again and sure enough it is working now. Cheers.
