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.

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.
Recently bought a Samsung I897 Captivate. Its a unlocked phone and I'm using it in Argentina with Movistar. My previous phone was a Motorola Milestone, and it sometimes changed the connection from 3G / HSDPA to 2G (EDGE), in 3G areas. The solution was to go to APN settings, enable "2G only", then disabling it, and the phone instantly switched to 3G again.
However, the Captivate doesn't have such option. Setting the phone to Flight Mode its useless, it will keep connecting in 2G.
Only solution I found at the moment was to go to Network Mode (*#0011#) then navigate to Network Control => Band Selection, selecting WCDMA only, and then enabling Automatic again.
That seems to reset the connection.
I searched in the market for free and paid apps to help me fix this issue, but I found nothing, only the Toggle 2G app, but it only works with Cyanogen Mod.
I have some questions:
If I set the connection to WCDMA only, then I'll have no signal at all in 2G areas, right?.
Does anyone know a quicker way to do this?. I tried to make a shortcut to ServiceMode with dg Quickcut but when I try to open it it crashed the phone.
Thanks in advance.

as of right now, there is no "fix" for this. the best you COULD do is to flash Eugene's VibrantHybrid ROM where the "use 2g networks only" option does exist, but you'll lose GPS (for now)

Thanks for the quick reply Kaik541.
Does the signal strength improve with that rom?.
Currently I'm using I897UCJH7 from samfirmware.

you should revert back to JH3 if you're going to use Hybrid (I don't believe JH7 is compatible yet, there are some issues that cropped up with SRE, so it would be safer to do JH3, or even better JF6). I've seen slightly better reception and MUCH better battery life running Hybrid

It seems it will be updated soon.
Maybe I'll give it a try.
Do you know if it removes the 850 band?.
I need it, because my carrier uses it for WCDMA.
Try this:
1. In the Market, download Any Cut. (This is a free app) 2. open Any Cut and choose New Shortcut 3. select Activity 4. Scroll down the list until you get to Phone Info 5. Select OK. (this will place the short cut on your homescreen) 6. Open the shortcut and scroll down until you see "Set Preferred Network Type" 7. Choose GSM only and you are set. This forces the phone to EGDE
I used this to force edge. Use google to download AnyCut, it doesn't exist on the market for the unknown reason

I just discovered Juice Defender. One of its features is to set phone to 2G automatically (seems very configurable). I haven't really had a chance to test it, but thought I'd mention it to you anyway

Thanks a lot. I use dg Quickcut for that.
But, I don't need to force EDGE, I need a way to force 3G .
The phone usually switchs to EDGE in 3G areas, and I need to change it back to 3G.
I've used your suggestion to make such shortcut, changed it to WCDMA only, clicked the Disable Radio button twice (because it didn't changed to 3G), and when it switched back to 3G, I changed back the network to GSM / CDMA auto.
What about WCDMA preferred?. Will it try to allways connect to 3G?.
can yall not just dial * # * # 4636 #*#* scroll to the bottom and chnage it there, just so happens i posted a how to earlier in the general section, works on stock ROMS afaik.
also GPS still works

read my previous post.
it has a WCDMA preferred WDMA only (only uses 3g) and a bunch of others. read my post in general for a more detailed explanation.

Thanks, but Mesasone pointed me to a great app in the market.
Its called Samservmode. It opens service mode without entering any codes.
Anyways, thanks for your help .
I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.
Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.
Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.
Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.
Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Is this not the same then as just shutting off data?

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.
I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.
The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.
ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.
I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!
I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!

the phone will do this automatically in either setting, just leave it on lte and it will have the better tech whenever it finds it and if it looses it it will switch to the lower one within specified thresholds. i know it will switch to 3g from LTE at -120dbm but i dont know what the threshold is for 3g-2g
Hi Guys,
I have been trying to find a way to connect to WCDMA mode only and not the "3G/2G (Auto Connect)" mode. I need to do this because 3G reception is little poor but the phone always stays in 2G mode and the internet is DAMN slow.
The Normal method in usual android phones is to type *#*#4636#*#* which brings up a Network selection menu, which doesn't work in our Note 5.
@developers: Can one of your ROM Control apps can be helpful here which have that option of changing Radio to "WCDMA" option only. I recall using a custom ROM once which had that development app built-in which allowed to do so.
PLEASE HELP!!
Bump!
No help possible?
Nothing?
