[Q] how to force change to 2G - Captivate Q&A, Help & Troubleshooting

Hi .. is there anyway to force our Captivate to connect to 2G only ? I can't find the option in the Network Setting.. I've also used the *#*#4636#*#* that I used to use back in the HTC Magic days, but it didn't work ..

tried using the power widget .. no go .. do you have any application in mind ?

There is a long dialer code but it is much easier to download the app called SamServMode from the market. That takes you into service mode where you select [1] Debug Screen, then [8] Phone Control, then [4] UE State Control, then [3] Change RAT to GSM. Im not sure if you then have to tap "Change MODE => GSM" or not but I do for good measure. Now no more 3G! This will revert on a reset but with SamServMode, it's so easy to change, it's not a big deal.

Been using this for a while as 3g signals at the office aren't that good. Although I just added the dialer code as a contact.

thanks for all the reply guys, I've also found another shortcode *#*#2263#*#* .. it's shorter and the menu is easier to understand

Rooting and Band Selection

I have exhausted every option known to me trying to get access to manual network band selection on the Captivate. The usual codes take me to the correct place, but I get an error message saying it's restricted. My question is will rooting the phone give me access to those menu options? I want the ability to lock the phone to GSM/EDGE or WCDMA at will. If anyone knows a solution to this, please let me know. To clarify: I am not looking to just turn off data and the *#*#info#*#* route doesn't work. Thanks.
Can anyone with a rooted Captivate confirm that you can or cannot access the menu to lock to GSM?

Hi,
No need to Root the phone at all. Just dial *#*#4636#*#* then click on "phone Information" scroll down to the drop down menu & click on it, click on "WCDMA" only & go back. done

What do you mean by "it does nothign"? I did it & working.
Setting 3G only or 2G only
I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.
THANK YOU!!!!!!!!!!!!!!!!
Doesn't survive a reboot but it's a start.

thanks for this.
but to take this a bit further, is there any way to automate this via a widget?
^Not from a widget in the market
They tend to wind up turning data off all together. Im sure it can be done though

Phone settings, wireless and network, network mode. I don't know if it's present in all roms though. There you can change the network band type

You have been mixed up....
Clear your mind,
*#????# - service menu is service menu,
root is root,
These are two different thing.
I'm not sure if band selection is disabled on all Captivate roms (it definitely is on some) but I have ran a number of I9000-based ones, all of which permitted band selection. Try dialing *#2263# to enter service mode and see if you're able to select the desired band. I'm using Perception 10.1, on which I can use this to modify the band settings and it is retained through a reboot.
I'm running perception 10 and there is an option in settings>wireless and network>mobile network>network mode> wcdma only or GSM only or auto.

Band selection in settings is only in I9000-based roms!!! It's non-available in Cappy-based roms!

Widget Request - Toggle 3G/Edge

In AT&T's infinite wisdom, they removed the menu option for switching between the 3G and 2G/Edge networks. I found the following on the forums on how to force 3g or 2g on the Captivate.
Enter the Phone app.
Dial *#*#197328640#*#*
Select [1] DEBUG SCREEN
Select [8] PHONE CONTROL
Select [4] UE STATE CONTROL
If you want 2G, select:
[3] CHANGE RAT TO GSM
If you want 3G, select:
[2] CHANGE RAT TO WCDMA

Do any of you android developers have the ability to create a widget that does this for us? Something simple like press it once and you are in 2G, press it again and you are back to 3G? I'd pay $2 for that (or buy you a couple beers if you live in Denver.)
Backstory: I get HORRIBLE 3G reception at the office. So my phone tries desperately to find the 3G network with very little love. So I don't get 3G speeds but my battery gets drained. Edge works awesome at the office and is fine for getting emails and synching. I'd like to easily go to Edge in the office and then turn it back to 3G when I go out for lunch or go home. I've looked through the market and have not found something that does this in a simple way. If you read this and would be interested in such a widget, please add a comment so developers can see demand beyond me.

here u go its the service menu option

The OP just detailed the process for switching the radios in their post... They know how to do that already. What they are looking for is a widget that can do this so you don't hebert to fumble around jun the service menu.
I'll add five bucks to they put somebody can get it done.

This would be awesome if someone could make it happen. The SGS info works really well and did make it easier, but it's still somewhat of a hassle going through all those menus.
Yeah...that's better, but still not what I was looking for. I hadn't seen that app yet, so thanks for pointing it out. I'd still like a widget that allows me to toggle 2G/3G with the push of a button.

Sorry If I didnt make that clear, but my post is a program that gets you to the service menu without entering it manually,Yes you still have 2 do the steps but easier as far as getting into the service menu. I do understand that you are looking for a 1 button switch back and forth and hopefully someone will find it or make 1.
I have tried using the APN on/off widget, but found it ineffective. Wish some one could come up with an widget that Actually works on ALL AT&T ANDROID DEVICES as AT&T disables the toggle between 3G and Edge feature.
Smoda widget kind of does what you want, although I think it may disable data all together.
Can't be done unless you root your phone and install a custom ROM. Thats why you can't find a widget to do it.
I've written Toggle 2G that can do exactly what your asking for and combined with the Locale app can even do it automatically. But will require installing a custom ROM on your phone.
Cheers,
MB
P.S. I live in Centennial, so I'll take you up on your beer offer if this helps
Edit: I haven't done much research on the Captivate, so I don't know if there are any ROMs that will work.
@sfernadez:
I have been using that app for a while now... it makes it slightly more convenient, but it's not the simple 2G/3G toggle that we are looking for.
All of the widgets and apps that are supposed to do this just turn data off altogether on the Captivate.

Hasn't been tested on the Captivate, as far as I know, but it's worth a shot.

It's been a while since anyone has posted any updates here! is there any news if this had been tested to work on the Captivate Glide? there had not been any custom roms developed as of yet for this device.

Why is "Select Network" greyed out even on unlocked phone?

Settings -> More -> Mobile Network -> Select Networks option is greyed out! My carrier wants me to manually select Vodafone 3G instead of Vodafone to get 3G. How do I do this?
why do you care about the name?
the one thats grayed out is the band select.
google market> search > phone info > first menu> set your own band.

it doesnt connect to 3g because there's no 3g network in your area, chose the 2g one or vice versa
Not that simple. Here's what happened: http://forum.xda-developers.com/showthread.php?t=2034540
On phone information there are 2 ways to change things.
1. Set preferred network type. Options are:
WCDMA preferred,GMS only,WCDMA only,GSM auto (PRL),CDMA auto (PRL),CDMA only,EvDo only,GSM/CDMA auto (PRL),LTE/CDMA/EvDo,LTE/GSM/WCDMA,LTE/CDMA/EvDo/GSM/WCDMA(*),LTE only,LTE/WCDMA,Unknown
(*) default
2. Menu -> Select radio band. Options are:
USA Band,Cellular,PCS,2-GMHz IMT2000
DON'T CHANGE THIS ONE!
Yes, I agree (now that I've learned it the hard way!). But the "band select" that souljaboy posted above is for the second option that shouldn't be messed with!

I found the anser for this the other day. You first have to go into Network operators and unckeck Select automatically.
i found the solution
Go to phone settings and you under "SIM Management", default 3g 4g connection, change the SIM preference.

Finallyyyy i got 3G in all countries

hello every body
more than year searching on how to get 3G on HTC M8 sprint a the band not compitable with my country
i tried many ways and got the easiest one by luck
simple steps
just download application named hidden android setting below link
https: // play .google .com/store/apps/details?id=com. kasitskyi. hiddensettings
then choose BandMode
from the check list choose Automatic
thats all
waiting your feed back
It won't allow you to modify the APN list so I cannot set up 3g usage.
the device should be rooted
note** i used cyanogenmods rom maybe this effect

After doing this, you were able to see "3G" or "H" when you activate data? I think even in 3G, sprint htc m8 shows G only... There's an app called "4G switch" on playstore I use to switch modes. It's red icon with switch symbol. And it doesn't require root. Works on stock rom.

Use anyone of your choice man. Wcdma is 3g, GSM is 2g.
Just upgrade to Marshmallow, you'll get HSPDA - no more EDGE... Drawback is you'll lose native Hotspot functionality; I don't know why but the feature disappears once you upgrade...

Yes : download activity launcher
https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher
Then stretch for "hidden", and open the app that go to a phone icon named hidden something.
Then, in the hamburger menu choose the band selection mode, pick the bands you want to lock to, then activate it
go back to "Network mode" from the hamburger menu and pick "band selection mode".
That's all

Mate,thanks but i am on android 9 with note 9 rooted with the last updates and samsung removed that hidden network app with the last updates. I installed it manually as a system app yet it didn't work .I mean the root permissions in the file system not the typical permissions apps ask for camera,contacts etc when installing or launching. Also I heard something called "hns" removed with the updates and that's why it doesn't work if i even install that app manually.

No problem friend thanks a lot for your try.
Will this work for unrooted stock oreo to lock data from switching towers constantly?
I have a N9600 (TGY) device and I tried to manually select bands using instructions from this video:
youtube.com/watch?v=K-DN0q64lRw
I have the latest version of Android 10 available for this device.
I decided I'd rather NOT fiddle with these settings further and reverted everything... Now after a reboot, my device refuses to connect to the network. For example, I cannot make a phone call... Only after going to "Call Settings & Selecting "Automatic", I'm able to make phone calls again.
Any idea how to set everything back to default settings? I don't like the fact that the phone cannot make calls after a reboot as of now ... I'm using this device on AT&T, so what should the default selection be?
Thanks

This app lets you lock 5G/LTE/4G/3G/2G bands on most Samsung phones running the latest One UI updates: https://www.reddit.com/r/samsung/comments/g49ocr/app_samsung_band_selection_app/
After much headache with this issue, I found a method that works where the "Band Selection" menu doesn't work (this method is confirmed working on my Galaxy Note 8). Thanks @fasho:
https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (from an apk mirror as it is no longer available on the play store), and then run ServiceMode as root. Follow the linked instructions further to disable unwanted LTE bands.
