Turn off 3g on the fly

So far my Touch Pro has been great, but the battery life has been a bit lacking.
I'm wondering if there is a program which can turn on and off 3G easily and quickly, but without rebooting the phone, so you can turn on 3G when you want to surf the web for 10-15 minutes, but turn it off for the majority of the day to conserve battery.
Any ideas?
Regards

If your ROM has Band Selection enabled, go to Settings -> Phone -> Band and you can choose GSM (2G) or UMTS (3G)

What do I change? Under Select Network Type there's Auto, GSM, or WCDMA
or under Select your GSM/UTMS band there's Auto, GSM(900+1800)+UMTS(2100), GSM(1900+850)+UTMS(1900+850) or UTMS(2100+800)
At the moment both are on auto. Which do I want for just GSM and which would I want for 3G when I want it on?
Thanks for the reply

you would want Select Network Type to be set to GSM for GSM/EDGE only, and WCDMA for UMTS/HSDPA/HSUPA.
(the other setting is to choose which frequencies you're using)

It would appear that there's exactly the app I was looking for which turns 3G on and off. It's here

3G Auto Mode - What is It?

What is this in the communications settings?
3G Auto Mode

I believe that just means that your phone will use 3G if it is available. If 3G is not available or the option is switched to off, your phone will use 2G (EDGE) instead,

Set your Raphael to use 3G when available.
If you switch it off, it will use 2G network, even if 3G is available..

Ok guys, that makes sense, thank you.
I have another question along the same lines. After I turned the 3G auto mode ON, I see this "H" Appear every once in a while in the top bar. What is it?

That's 3G. The 'H' stands for 'HSDPA', so when it appears, it basically means you're using 3G instead of 2G (EDGE, which would appear as an 'E' instead of an 'H').

All icons, explained :
G --> GPRS, 2.5G, the slowest data connection
E --> EDGE, 2.75G, faster than GPRS
3G --> UMTS, much faster than EDGE
H --> HSDPA (may be HSUPA also..), the fastest data connection available on Raphael..

How do I select UMTS/WCDMA mode only?

Well guys I am a newbie to the Android world!!
On my earlier Nokia I used to have three options for the Network Mode under the Phone Settings, viz. , Dual Mode, UMTS, GSM. Since in my area the 3G signal is a bit weak I used to select UMTS only, so that the phone doesn't switch over to 2G automatically.
However, in my android device (Samsung GT-I5503) the only option under the Mobile Networks which is anything similar to a Network Mode selection is the Use Only 2G networks checkbox. I believe it disables Dual Mode and allows GSM network only, in the Android device. So Android Gurus and Forum Moderators, do you guys know of any method or software which can select 3G network only!!
Please help me guys as the 3G reception in my network is a bit weak, Android doesn't switch over to 3G!!
Oh and BTW, I'm getting a really good 2G signal. The Signal Bar is 4/4 most of the time!!

@Mods: Could you please change the title of the thread to "How do I select UMTS/WCDMA only, on Samsung Galaxy 5 (GT-I5503)?"

[Tweak] FORCE 4G with anycut

This is actually on old hack I used from the G1 forum. This is really useful if you are in an area where 4G or 3G is weak and you phone keeps switching back and forth to edge. Very annoying...
Install AnyCut from market
Open AnyCut and click NEW SHORTCUT
Click ACTIVITY
Scroll down to "Phone Info" and select that.
I renamed the shortcut "FORCE 4G" but you could name it anything.
Click OK
Now open the shortcut on your home screen, and scroll down to the bar that spans across the whole screen. This is the bar that controls all your network types listed here.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all. (FORCE 4G!)
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (MY FAVORITE ON G2X)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
Im sure this hack works on all android devices, less options will show for phones w/o that capability.
BetterCut will obviously also work and youll be able to customize an icon for the shortcut

Menu, settings, wireless and networks, mobile networks, network mode, wcdma only.
Won't that do the same thing without all the work?

*#*#4636#*#*
Phone information
Scroll down
Change WCDMA preferred to WCDMA Only
Same thing as well... If youre that desperate for "4g", however, if you lose 4g/3g you lose ALL SERVICE, I believe. I had played with these settings on my n1 last year. In the end, I found WCDMA preferred was the most reliable ;-)

He's talking about changing the hidden menu. There are two menus, if you change it in the non-hidden menu and not on the hidden menu, is different.

This should probably be moved to themes and apps or general. Nothing really developed here, no offense.

This isn't the hidden menu this is just the phone info menu that you can access with *#*#4636#*#*

Thanks! I skirt the edge of society and there are a few ROMs that I really like to use that don't have this option built-in. Bionix has it but CM7/Faux and others do not have the option available from the mobile networks menu. I'm sure it adds to radio life if you set it to stick with the highest signal since the phone won't be switching towers.

I have a post about this in the Q&A section, but have any of you experience the G2X using only 1X or CDMA data frequencies other than 4g?

[Guide] How to increase S4 GSM signal strengt

Many of you know that the sore point of this phone is the quality of signal reception. Informing about the mode of action of the baseband, and reading the feedback from users about their various tests, always read from their words unsatisfied a search of a radio version that could improve the reception of the terminal (and thus battery life).
Since I live in a poor signal area on the Vodafone network IT (and no LTE coverage), I thought that perhaps the solution could meet elsewhere. After PimpMyRom installation , under "Device Hidden Menu > Access Hidden Menu > Telephone informations" there is a menù was set to a profile "LTE / GSM auto (PRL)".
By clicking on the drop-down menu, I selected GSM Auto (PRL), then rebooted, and i have greatly improved connectivity to the network.
Below there is a legend about the most important items. Take the test and reported your opinions.
I recommend GSM Auto (PRL) for best battery consumption allowing the automatic signal 2G/3G, preferring to 2G when the 3G signal is weak.
- WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.

Hi, i`m on SlimRom 4.3 Beta 4
Everytime i try to change my Phone Profile to GSM Auto or something else in the List it crashes and says:
The Process: com.android.phone was quitted.
Any Suggestions what to do?
The LTE is draining my Battery like Hell!

It's strange because is a System related setting that can be changed without problems...maybe in your case this parameter is linked to something other. In my case all went ok only selecting other profile (i discovered that if you select "2G only" into telephone settings, this string change to GSM Only). So my suspicious is related to a linkage to some other driver that won't make you possible to change it.
We have to investigate. However my battery drain seems lowered combined with "Wifi tx power" + "iwconfig" file used for reduce Wifi signal power to 11dB. Other small things and Jelly pure ROM 4.3 will be perfect for daily drainage use
