On my K3 Note, I can't pick preferred network mode on ANY rom/firmware.
I've tried everything, but it always sets the default preference which is 4G>3G>2G.
What I need though is permanent 2G and I can't set it this way. (4G signal is weak on my operator and then it keeps switching between 4G and 2G over and over)
Is there any way to entirely disable or block 4G on a phone so it will never set that mode again?
Any help would be appreciated!
Any help guys? No one knows what could be the issue?
I tried using the *#*#4636#*#* code and set the "GSM Only" but it still doesn't work.
Is anyone else having the same issue?
Edit:
Also what I've noticed is that while using CyanogenMod (atm), it stays on 2G until I turn the screen off. Then it goes back to 4G.
After turning the screen back on it then goes back to 2G again.
same problem here when dialling number it said invalid MMI code and when switching to 4g the other network appear no signal.. hope someone here have solution. i try several roms but same problem issue.
Well after a lot of fiddling, it seems it works on the stock firmware, but the mobile operator as himself has quite troubling network.
But I think we are slowly coming to a conclusion..

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?
maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.
When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?
Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available
Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives
Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!
:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location
I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".
I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).
If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.
I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave
have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"
Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....
i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks
participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?
Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks
I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.
solution for this
Guys....even I had the same problem.....but was able to solve it.....
Go to settings >apps>all >Google framework services in this disable it and clear data and again enable it....
Enjoy 3g once again ....it worked for me

I tried this as soon as I put WCDMA preferred I lose signal, I have tried doing this in several locations as I live in the country, tried at my school where my friends get H+ and I still lose connection. tried going back to stock still the same issue
Can someone fixed this problem? "WCDMA only" mode make my N4 lost signal.

Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks
Hello everyone, I'm experiencing a terrible situation with my OPT - O2 2.1.2.
I used to rely on Intelli3G (an Xposed module that switches mobile radio to 2G when screen is off to save battery and then reverts back to LTE on screen on).
This worked perfectly with OPO but I noticed strange disconnections of the mobile data with no possibility to switch on again without rebooting.
I've studied what happens when the phone is asked to switch to 2G Only:
with the *#*#4636#*#* menu I noticed that the network type says "unknown,unknown" and there's nothing I can do to get things working again until a reboot.
In this situation I see that there's signal, triangle is full, but I'm unreachable.
If I keep my radio to WCDMA preferred (with screen off) or LTE/GSM (while using the phone) everything works fine (so far).
My carrier is Vodafone IT, I already changed my SIM card for I thought I had a faulty one.
Anyone else is experiencing these disconnections?

I'm having similar issues. I can only connect with one SIM at a time. One SIM card only connects via 2G. I think I need to go buy a new phone. I've even restored back to old versions without luck. I've flashed the modem too. No luck. This is bad for someone on the road like me. I'm missing critical calls. I'm back to using two phones as a work around.
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option
