Im on OOS 4.1.5 Using airtel sim. Eventhough 3g netwrk is available in my area, if I set 2g/3g/4g mode in netwrk menu, it locks on 2g mode only.
Only for few min it stay on 3g and den comes back to 2g mode.
On custom roms we have option to select only 3g mode. Buy in OOS it's not.
I have even tried to set UTMS mode in *#, #4636#*#* but it didn't worked.

Self tried solution
I faced the same problem in my OnePlus 5T, and this is what I did:
Install "android hidden settings" App from Playstore. Go to RadioInfo. Set preferred network type as "LTE/WCDMA". Disable the Radio Power by turning its switch to Off (Wait as it takes a couple of seconds to do so). After about 1/2 a minute, turn it on again. That's how I resolved this problem in my OnePlus 5T.

my phone can not connect to 3G networks in most of our city, while it used to work just fine in these same places. at first i thought there must be something wrong with the carrier's base stations. but today i tested my SIM card on another LU6200(Korean version of Nitro HD) and it works perfectly both on 3G and 2g networks on that phone. but when i put it back into my phone, it can only get 2G signal. if i set the Preferred Network Type to WCDMA ONLY, it got no signal with just a cross on the signal bar. i have to put it back into GSM ONLY mode to receive signal.if i go out, i can get partial 3G connectivity here and there, but not consistently. sometimes even if i have full 3G bar signals on the status bar, i can not make calls or connect to the internet.i've got this problem probably after i tried to forcibly go into the Phone Info menu.i got repetitive " the process com.android.phone has stopped unexpectedly" promps , and i just ignored it and tried again. now ,2 options are missing from the menu, LTE/WCDMA/GSM and LTE Global.in place of them, it's UNKNOWN. i already tried flashing KDZ package of no avail. Does this mean a hardware malfucntion or software glitch?Please help!Thank you in advance

Well you do HAVE GSM only selected. THATS 2G(EDGE)
for 3G you would need to select WCDMA

i have been experiencing several problems with S4 mini 9192 since i bought it one month back and one of these is that the phone does not switch data between the 2 sims correctly.
to have the data work correctly on any sim, all the below must be done
1-select the sim you want to use for data in sim card manager/data service network
2-have the same sim configured as gsm/wcdma (auto connect) on connections/more networks/mobile networks/network mode
when you select option one, the phone tries to perform task 2 too, but fails, thus the data sim is left in "GSM only mode" and will only have edge data, never connecting to HSPA/ 3G.
here is what i have to do each time to switch data from Sim-1 to Sim-2 (screenshots attached)View attachment Screenshots.zip
Screenshot 1- you will notice data is set for sim 1 and HSPA is active
Screenshot 2- select sim 2 for data
Screenshot 3- the phone will disconnect data on sim 1 to switch
Screenshot 4-phone will try to set sim 2 as "gsm/wcdma (auto connect)"
Screenshot 5- but gives alert message and fails
Screenshot 6- sim 1 is still on "gsm/wcdma (auto connect)" and the data connection for sim 2 is only edge
Screenshot 7- Sim 2 is still on "gsm only" and does not connect on hspa no matter how long you wait
Screenshot 8- for data on sim 2 to work properly, first change sim 1 to gsm only
Screenshot 9- then change sim 2 to "gsm/wcdma (auto connect)" and wait for 5 seconds, the phone will connect on HSPA .. success
now my big question is, does this happen to everyone with s4 mini 9192, or is it just me??
by the way, this occurs on both my Egypt stock firmware and the j2 india firmware i just flashed.
i tested a friend's Galaxy Mega 5.8 Duos, and the phone performs both steps by itself, with no need to perform the 2nd step manually.

I have had the same problem with my model that I bought in Australia. Your solution worked well for me as this is one frustration that I've been blaming on the network rather than the phone for the past week (because I was ignoring the error messages). I would hope a software update is in the works to fix this issue as it will get quite annoying in time.
I have the very same issue, plus the second sim slot only work in GPRS, and I try 4 rom before getting block by ****ing knox problem.
Sorry to dig this out but i havent found any answer to this yet.
is there any way to get a widget or a script or anything so that one can easily switch data connection from one sim to the other by one click? Or even automatically depending on which sim is in its home network?
This would be awesome as i'm hopping across the border twice a day and switching data connection all the time is a pain in the a**.
Thanks a lot for any answers!
I am also looking for answers for this.
Out on the site I work at they only have 3G towers but I have no data access on my work phone so I need to use my personal sim for checking email, then switch back so I can use work phone again.
Known issue on the phone it sucks

it is happened to users who using wcdma or other non-cdma users.
Go to Settings -> Network -> choose CDMA subscription -> check RUIM
then open dialer,type *#*#4636#*#*,phone information,choose Select prefered network type to WCDMA prefered, reboot
now you should get signal on your phone,if not,check if network type is LTE,then switch it to 3G or 2G,then it should have signal now.
press the thanks button if that helps you

Hi
It seems I got the issue resloved by running into another issue. First of all there is no such settings in my menu and second off all all the codes I try and when I press the last corrector the whole code disappears and nothing happens.Even *#06#
doesnot work
Also there seems to be a signal dropping issue. btw I am using F180L which is similar to E975
Also Thanx so much for trying

Hello,
since I updated my OnePlus 3 to the newest Resurrection Remix I have problems with LTE/4g. If i activate Mobile Data, i only get EDGE with a low bandwidth. I called my Mobile Provider and they said, that in my area LTE is working perfect. I eject the SIM Card and placed it into another smartphone and after two sec. i get LTE/4g with a high bandwith. A factory reset, returning to Stock Rom, deleting the APNs didnt work either. Is there any soultion fo this issue?
Maybe I crashed my modem ? Is it possible to flash everything back to Stock ?
Thanks
type *#*#4636#*#* in your phone dialer, phone info, scroll down and set prefered network type to LTE only. you will be unable to call while in this mode so do not have it turned on. just test it if your 4g works

well then your phone is broken or your service provider is messing up. but you already called them and they said that it was all ok on their side. so that means there is certainly something wrong with your phone
I'm using two sims but I want to force the second sim to use a 2G networks only independently from my first sim. Is anyone able to do that?
Also when i manually select a 2G-network for the second sim, after a while it changes autonomous.
I've tried changing it from Test Menu (*#*#4636#*#*), from "TD-SCDMA, GSM/WCDMA and LTE" to "TD-SCDMA and GSM".
The setting persist until I rebooted the phone.
