Does anyone know how to enable 3G only on Vibrant????
I can see the option for 2G only, not for 3G... BTW my phone is rooted...
why would you want 3G only? when "2G only" is disabled... 3G is on but if there isn't 3G signal then it goes to alternative EDGE (2G) temporarily until 3G signal is available
"3G Only" isn't a feature.. and its pointless to have it as well

it will be pointless for T-Mobiles users. But it will makes sense for Wind Mobiles users (Canada) cause Wind only has 3G connection and doesn't have any 2G connection.
Ya, so now you know it's not pointless. So what's the solution?

I'm pretty sure by default with the 2G unchecked that it's on 3G mode.
It's not a feature, it's just what it is...it's always on 3G accessibility.

Use the code for Battery and General Info: *#*#4636#*#*
Towards the bottom there is an option for "Set preferred network type"
You can change that to only use the networks you want.
The descriptions of each of the choices are at the bottom of the linked post.
Hope that helps
I found that menu didn't work for me. I used that menu on my G1 and it worked great, but it seems to have no effect on the Vibrant.

That's the proper way to force 3g mode, and I do it on my phone it works great.
Also, another reason to force 3g only is if you live in a weak 3g area. I don't want to ride the edge network 60% of the time if I can force 3g and get it 100% of the time.
Hey none of the methods I read here work.
So after playing around with my phone a little bit, I discovered a way to actually lock 3g.
Again I'm not a phone expert, and I discovered this on my own, so use with caution, I don't want to be blaimed for a broken phone.
here is how I did, copy and pasted from another forum I posted these instructions in:
Tired of edge speeds, want to lock in 3g? Okay this next one, do at your own risk ask usual, use with caution. I kinda figured this one out on my own, through trial and error, so I’m not sure how stable or accurate, or even how safe it is to do this. I did notice though, if you screw up, you can use the factory reset code above and things should go back to factory defaults.
Okay…so again do at your own risk. Also by locking into 3g speeds, if you ever go into a non 3g area, or if your 3g signal is poor in your area, then your phone calls will drop and data will stop, unless you go back and set the phone to its default automatic gsm/cdma settings.
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands [*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Your phone should now be locked into 3g.
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!!

Do you have to do this each time you reboot the phone or are the settings get saved somehow?

Setting to WCDMA only does not change a thing.

Well i don't know what's up with your phone, but on my phone, it sets it to pick up wcdma only, like it says.

Probably has to do with my provider.
Thanks for your answer.
Hey all yes I am a newbie, but I have been using roms for a quite a while I love the customization of the HD2, we are switching services in a couple weeks to either Verizon or US Cellular but this issue is bugging me like crazy, I used to be able to use my phone in the parking lot at my job, we arent allowed to leave on break, used to get 2-3 bars and an Edge signal, in a place Tmobile says I should have great coverage over the last couple days I have gotten no signal what so ever in the same place I used to use my phone every single day for about a year. I sit there for my whole break trying to talk to my wife while refreshing networks, auto selecting it or manually gives me 4 full bars and an edge signal then it all goes away. I guess why I am posting it to see if anyone has suggestions to what I can do to fix it. The phone works fine at home and on the road just not near work anymore. I have always used different roms, and never had the issue at all, always full task 29 wipes, my current build is
CyanogenMod Version PARANOIDDROID
Kernel 2.6.32-ics_tytung_HWA_r2.4_uniMAC [email protected] #272
Baseband 15.42.50.11U_2.15.50.14
Any suggestions are appreciated! Thank you again! Jake
I well ask a obvious question, have you checked your APN's. I knowyou are getting a data signal but maybe one of the APNsettings need to be changed.
Also do you have you checked in Settings/Mobile network/Network mode. See if you have WCDMA only, GSM only, or WCDMA/GSM auto.

Thanks for the response, my only APN is epc.tmobile.com and I cannot locate the network mode... No network mode setting that I can find.
Edit:: Found it its set to WCDMA Preferred is that what it should be?

Try WCDMA/GSM auto that way your device can switch back and forth as needed between WCDMA or GSM as it needs to.
Hi,
I'm trying to set "Preferred Network Type" to "GSM auto (PRL)" on my Nexus 4 as my 3G coverage is really poor at work.
I get into the menu with *#*#4636#*#*, select "Phone information", choose the option in the drop down box. It works until I reboot the phone then have to start all over again.
Does anyone know if their is a line I can add to the built.prop file to make it stick?
TIA!

I know it's not the same as "Use only 2G networks", but you might try it until you can find a better solution.

No, that is not the solution I want. If signal from my provider is not present or too low, it fall back to a "Partner" one without any charge to me.
If WCDMA PREFERED is selected, it always try to look for and get back to my provider antenna instead of staying on the Partner antenna.
My battery drain like crazy this way, but if "GSM auto (PRL)" is selected it is much better battery drain wise plus we have a repeater indoor for this partner signal...

Sorry to resurrect and old thread, but I'm having the same issue. Did you ever figure it out?

npiper05,
Actually I would be glad that this post would be resurrect since I never did find a solution.
I am sure with the right line(s) added to to built.prop would do the trick but I don't know what to add.
If you ever, let me know.
Cheers!
I would like to know what can be edited as well to make it stick to gsm auto after a reboot. My data totally sucks and drops all the time with WCDMA. My data works with out any drops when set to GSM auto. If anyone can help us out it would be greatly appreciated.

In the *#*#4636#*#* menu, my preferred network doesn't have LTE/WCDMA/GSM Auto. It only has LTE/GSM Auto. I was wondering how I can get LTE/WCDMA/GSM Auto. I am on AOKP.
When I am on LTE/GSM Auto, I have a lot of drop calls.
I've noticed that using the dialer code: *#*#4636#*#* we can access a debugging menu.
Tap 'Phone Information' and you'll see a slew of information about the current connection status.
As you can also see, there's a drop down box labeled 'Set Preferred Network Type:' which allows you to change the cellular network type(just like in the Mobile network settings Menu). This is great if you are in a location and have a data connection but aren't getting any throughput. But there's also a drop down under box under the same 'Phone Information' debugging menu, on the top right(three button) that gives you an option of selecting the radio band as well.
My question is, will there be a way to implement into custom Roms or kernels to allow the radio bands and network types to switch to the best frequency with most data throughput?
Walking through my house, I have dead zones. In those dead zones I have to switch to 800mhz and change my type to LTE/WCDMA. Could we have an auto search for radio frequencies and the individual bands on those frequencies or will I always have to manually change them?
Correct me if I'm wrong, but I think the "Select Radio Band" is set to "Automatic" by default, and changing it to something else (like "Cellular 800"), prevents you from going back into automatic mode unless you reset your modem (easiest via TWRP).

Usually the modem resets to auto when I hard reboot. Either way, the automatic setting isn't doing its job.
