Force WCDMA Only

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

I know that. However, such settings are available in Nexus One.

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.

why no Edge network?

Hi all,
i am on O2 Germany network and using AT&T nexus one.
i get 2-3 bars of HSDPA(H /3G, 2-3Mbps) network at my work location but if i move little far from my seat (near to window) i get only GPRS(30-50 Kbps) network but my friends Iphone manages to get Edge network on same provider which my Nexus is not able to get.
can anyone tell me why is it happening so and also i have tested selecting EURO band under phone info settings but no use
TIA

go into the dialer and type *#*#4636#*#*, go to phone information and tell us what setting is selected under Set preferred network type

hmm thats not the issue then as WCDMA preferred can still grab an Edge signal, have you tried turning 3G off and see if you can grab Edge anywhere?

i have switched off 3G too but still i am not getting Edge........
can anyone help me plzzzzzzzzzz

Bump.......for the convenience of all to see and help me out

Seems to me you're never going to get 3G, so I'd personally set it to one of the other options, not WCDMA. Don't have the phone in front of me but think the option to pick is clear if you're only going to get EDGE.

[Q] Nexus One not working with the Bell Mobility network either voice or data?

I just received my Nexus One which I ordered through the Google Developer program (Brightstarcorp) and I'm not able to get it working with the Bell Mobility network for either voice or data
I have a signal bars on my N1 with a Bell Mobility SIM card but it dosen’t works.
When I slide down the notification bar it say "Bell" and try this to get it working.
I have tried all solutions and have the recommended settings on the phone (also running Froyo 2.2.1-Build number : FRG83).
- I tried my SIM to another Bell phone and it works.
- I tried another Bell SIM in my N1 and it did not work.
- I'm using an active data plan card not a prepaid card.
But it works with Rogers or Fido
I tried the following :
1.Go to Settings -> Wireless & Networks -> Mobile Networks -> Network Operators: after about 1 minute I see network the currently available Bell
I click on Bell and see a signal not working.
2. Go to the dialer and type in *#*#4636#*#* this bring a hidden menu
3. tap on "Phone Information" It list the current network as Bell and also showing the IMEI and the Phone number. The IMEI and phone number are correct.
4. Hit the menu button and press "Select radio band" and click on "Automatic" .
5. Still not working I make sure radio band is set to "Automatic" then go back to the previous screen and scroll all the way to the bottom. Click under "set preferred network type" and choose through until I find one that works 1. WCDMA preffered or WCDMA only or GSM auto (PRL) it takes a few seconds from the time I click until the settings take place, just watch the signal bar at the top of the screen until it changes. Even try the "unknown" network type at the bottom of the list if the others don't work.
All the above fails.
For those of you out there who have successfully activated the Nexus One on the Bell network could you let me know which version of the phone you have.
Thanks for your suggestions.

well i am sorry to say but i dont think that the phone will work with Bell. the dev phones as far as i know are all AWS. so the only way it is going to work is if you get a rogers sim and use it on edge or a wind/moblicity sim and you can use 3G. bell does not have an edge network to back up on.

That's true. Bell/Telus has only the 3g network. The developer phone will not work. It will use edge/2g on Rogers/Fido. And will be fully supported on Wind or Mobilicity.

Nexus One with a Bell Mobility it dosen’t works!!
About Videotron?
Thanks

[Q] is there a way to force LTE?

like my phone can just sit on 3G, in the same place,while not moving
but if i reboot my phone, it'll pop on to LTE (if its available in that area)
but i reboot it in known LTE areas (when showing 3G)
anyway to force LTE, without rebooting the phone?
or is there some time schedule where it checks to see if LTE is available that I can change?

Yes which model u have? Its in the secret menu

I don't have the Sprint version so I don't know if this works but you can try https://www.youtube.com/watch?v=bSrtUw8D9_w as this method worked for the very similar LG G2 for Sprint.

I feel for you buddy because this phone is blazing fast on LTE

Hahaha you're absolutely right. I knew just by reading the thread. Sprint is the worst! My HTC One on Sprint was amazing but I couldn't ever hold on to an LTE connection for more then 30 seconds. Unlimited data is useless if your only on their horribly slow 3g

Sprint does suck, if i didnt have 4 other people on my account that would have to get new phones/account etc, I would have been switched.
but that video i think was to turn on LTE, my LTE is on, but for some reason wouldnt search/connect to LTE when it was available all the time
however i went into my mobile connection settings, and changed it from "LTE/CDMA" to Global
now it seems to switch to LTE when its in an LTE area. LTE icon comes up without me having to reboot, i'll keep a watch on it for a few days to see if indeed that was the solution
by the way, anybody now what the "global" option is? compared to LTE/CDMA

I'm pretty sure the global setting is to allow it to connect to GSM carriers in the event that the device is unlocked and the APN is changed accordingly.

I have the same problem in brazil, looks like a problem with the Phone. I had a Samsung S4 that worked with full signal in 4G in my home, now that I moved to LG G Flex it also works full signal 4G in home, but when I move to some place where is Edge then go Back to home, it never moves back to LTE automatically. I need to restart or change the NetworkMode manually to make it back working in 4G.
I think the phone has a problem to automatic search and change the Network mode.

anyone know how to enable only lte yet? i've tried all different kinds of secret menu codes and cant figure it out.

Answer
How to access the hidden service menu on LG G Flex:
For AT&T: Go to dialer and enter 3845#*950#
For T-Mobile: Go to dialer and enter 3845#*959#
For Sprint: Go to dialer and enter 3845#*995#
Once you're in the hidden menu, go to LTE-Only > Modem Settings > RAT Selection > LTE only
Enjoy!

Any way to set data to use LTE only (and not 2G/3G)?

I'm missing the option to set my device to 4G only. Under "Settings" -> "Network & internet" -> "Mobile network" -> "Preferred network type" I can switch only between "2G/3G/4G" and "2G/3G". I miss further options and especially to set it on "4G" or LTE only. Because my network provider is pretty bad at 3G but quite good at 4G, even when 3G signal is much stronger and 4G signal is weak.
I don't care if I can't take voice calls in this mode.
Edit: I see there are apps on the store to do this. Though would be great to do it within the ROM.

Telefonica (former E-Plus) in Germany. As far as I know, Voice over LTE doesn't work with them.

do you have problems that the phone stays at H+ and not switching to 4G?

My old phone did, when LTE signal was weak (but still available), and I assume, any other phone will do so as well. But data was much more reliable within 4G than 3G, even when signal was weak.
I play a gps-based online multiplayer game and whenever someone complained about bad data, I hinted to set their phone to LTE only.

If u want to play game while having mobile data only mode activated then use option mobile data only in "game genie" while playing a game and option appears on either side of the phone to activate no calls no alerts option along with the one you are looking for.
Hope it helps.

Anyone knows the actual difference between 4G and 4G+ icon on top bar? I've got the international version with MEO provider (Portugal), and I never saw the 4G+ icon active.

4G+ Means LTE-Advanced aka True 4G, and it is faster than 4G. The only difference is the maximium theoretical speed, bandwidth and minimium latency you can get. 4G can reach speeds up to 100Mbit/s, while the 4G+ (LTE-A) can reach up to or over 1GBit/s, with less than a few milliseconds of latency.

As far as I see, this option does not set "LTE only" but data only. What I need is to set the phone to LTE only. Thanks anyway.
