Try typing *#*#4636#*#* into your dialer and trying to turn on 4G that way if it's off.

if this method is not working, install force lte app then set to lte only option...
I found the settings,what should I do?
My phone frequently changes from the 4G network to the 2G network (E)
I have tried to change from the networking menu * # * # 4636 # * # * to force, but in the end it returns to the same GSM / WCDMA / LTE configuration and the error persists.Any solution?

Hi all,
Would like to check if anyone knows how could i set "WCDMA Only" (3G Only) on Galaxy S?
I can only Force 2G only via the settings menu, but not 3G only.
Managed to access the "Phone Info" menu via *#*#4636#*#*, selected "WCDMA Only" from the dropdown box.
However, nothing seemed to be set nor i see any button to save the choice?
Anyone happen to know how can i have it set? Or i could manually set it by applying some settings somewhere?
Thanks alot!
you cant force 3g... you would get no signal if you didnt have a 3g connection

It is also available on the HTC Desire :
WCDMA only
GSM/WCDMA auto
GSM only
*#*#197328640#*#* > debug screen > phone control > network control > band selection
You need to do this after each reboot though as it does not stick.
Is there a way to shortcut this with anycut?

The app Network simplifies the procedure quite a bit. Haven't actually gone into a low signal spot yet to see if it fully works as intended though.

thank you very much..i have been searching this high and low...you save my day..
Thank you so much! This helped me diagnose the SGS and see if I have 1900 3G in my area (1 bar). here's a tip that I used for quick access to the debug screen just as a trial and it actually worked
Enter ONLY *#*#197328640#*# then hit add to contacts (notice there is no * at the end).
Give it a name (Samsung Debug Screen) and tap to edit the number and enter the final * at the end.
Save and exit. Now whenever u want to enter debug mode to change the network or other stuff just type *#*# and it should appear. Tap on the contact and voila!

My operator doesn't have a 2G network... all they have is 3G. There's no point in my phone looking for anything other than a 3G network.
Solution added to FAQ
sorry to ask if this is already answered but how exactly to i get to CONFIRM my wcdma only selection? i check it and nothing happens, data connection stays on "G" symbol. I know for sure that at the place where i tested i get NO 3g signal. which means probably that i should be losing all signal after choosing wcdma only. that does not happen. also if i close the phone info app and reopen it, choice gets back to default (3g/gprs).
any help appreciated... I really need this.
forcing to only 3g is a bad move, i tested it on my n1 and i kept dropping calls once 3g lost signal.

Its available in the new firmware I9000XWJM1
Hey, its there in I9000XWJM1 and tested working great as expected! However its a beta so you may see other issues. Not sure if its there in latest stable.
Just to confirm, i upgraded my firmware to XWJM5 today, and i noticed that in settings > wireless and network > mobile networks, there's a new menu 'network mode' in which there's 3 options - auto / gsm only / wcdma only. Nice touch!
In answer to the cynics, there are times when browsing, when the phone is borderline whether to give you 2g or 3g, it does come in handy, and it's safer too, as if i have to browse on 2g it makes me want to smash the phone up!!

LOL "safer"
@OP Although 'WCDMA only' mode may not be a good idea and hence not recommended but just to confirm
my current Build i9000XXJPH have following three modes
GSM/WCDMA (auto mode)
GSM only
WCDMA only
JM8 build also have this mode. I noticed that when I flash the i9000M (bell version) previously it didn't have these modes.
I was earlier having Mate 9, in which i was able to use to switch to LTE ONLY mode very swiftly using netswitch app, to use Vodafone India 4g network. My mate 9 used to show 4g only signals and i was able to use data only network as my area was having issues with 3g network.
Now i got a new Note 8 Dual sim exynos model. Using some third party apps from play store, iam able to select LTE ONLY mode (only on the sim which has been selected as Calling sim). But it displays no signal after forcing to 4G only mode.
Please somebody help, so that i can use Vodafone India 4g network.
In the same area, when i use the same sim in a snapdragon Redmi Phone, and select the LTE only mode using *#*#4636#*#*, instantly that REDMI phone switches to LTE mode and shows full signals and i can use 4g data.
Somebody please help.

Sir, you are the man. Thank's a lot for this lovely app.
You shall be mine as well.
Especially since the app "shortcut master (secret codes)" stopped working for me under Android Pie, your app successfully calls the network mode selection menu.
Many thanks for that great hint!
Link is not working pls tell me the name of the app
You may use this link instead.

hi
i got the phone from korea, the problem is when connecting to 4G the phone would lose internet and calls then lose the network, i get a message saying "failed to register to network (15)" but if i forced the phone to connect to 3G then it works fine. here's what i tried to fix the problem :
turning off the mobile network then turning it on
resetting the network settings
removing NR Whitelist
and none of them fixed the issue. there's a korean menu in the service mode, but i didn't miss with it. i have attached screen shots of the software information and the korean menu in the service menu.
Who provides your service? Have you tried going into network settings and APN and see what that says
If it is a Korean phone and you aren't in Korea and it is locked into the network then you won't be able to get service somewhere else I don't think

Hello
I just got this phone and set it up. Its a Global version 13.0.4 SKDMIXM.
I am on TMoblie USA - the phone is working great on LTE and 5G .
I am not able to see the Network preference under wifi calling where is can select Prefered Wifi Calling.
It appears that its running on default Prefered Cellular - because I can only see the VoLTE symbol on top.
Can someone help me in fixing this configuration to select Prefered Wifi Calling ? TIA

Hello, I'm using a 11T Pro Dual SIM India model with India SIM in Slot 1 and TMO SIM in Slot 2.
I have not found the specific setting to make Wifi Calling "Preferred" but, my phone does indicate Vo WiFi even when I have Wifi connected and Mobile Data turned on too once Wifi Calling is enabled as below.
Apparently the Voice Over WiFi Settings (at least here on my phone) only show up for SIM 1, does not show for SIM 2.
Attached are sample screenshots where the Settings are under SIM 1.
Steps to get there-
Settings > SIM cards & mobile networks > Click on SIM 1
All the way down, last Setting is "Wi-Fi Calls" to enable "Make calls using Wi-Fi".
Hope this helps.

Operators can disable this menu if they want to lock you onto Wifi preferred or cellular preferred. Does this only happen with this phone or does it also happen with the SIM in another Android phone?

There's a possibility of TMO-US not supporting WiFi calling on the Xiaomi 11T (Global), perhaps.
Although, I have been using various Unlocked phones (Nokia & Samsung) on TMO-US for the past few years & have practically never had issues with WiFi calling on any. Shall have to test it once I'm back. Won't be for some time.
Is your phone on the latest firmware? Try updating it to check if there's a new update available
which hopefully can solve your issue.
Couple of options to test, in case you have not already tested them-
a) leave WiFi Calling Enabled then disable the VoLTE feature and check if WiFi calling works?
b) disable Mobile Data, WiFi Calling enabled with WiFi connected and check if WiFi Calling works.
c) some users have had to ensure their E911 address is correctly in place on the TMO account too.

I had a working One Plus 6 - so I know TMO has VoWifi - I use it a lot due to poor reception at home .
The current workaround to force VoWIFI is
Turn On Airplane MOde
Turn ON WiFi only
then it works in VOWIFI with out any issues
I know I am missing a menu Item that can toggle this setting . I would prefer having that setting but its not a breaker for now . The phone works with all the Network features of TMO , LTE , 4G , 5G etc . No visual voicemail thats all.
Thanks

Thanks - this code is what got me to where I am now . I think from other articles - the mbn config may require some tweaking - but it refuses to give me access to it when i use *#*#663368378#*#*
Same access issue here too.
Wish you luck.
Pinging to see if there is a soln. in future.
