For 3G Set It To WCDMA
For 2G Set It To GSM Only
If Set On Auto Mode U Get Default Settings From Operator i.e if U Have 2G Plan U Get Edge And If You Are On 3G Plan You Get 3G
Moreover The Signal Also Depend On Area if there is no 3G support in that area u only get 2G

There is NO switch like that, if you want only 2G then simply set the phone to "GSM only" and it will only get the slow EDGE speeds regardless of what area you are in.
If you do not set the phone for GSM only then the phone will automatically switch to 3G/4G speeds if those speeds are available in whatever area you are in.
Whenever you are in a 3G/4G area you will see a little icon in your notification bar if you have not set the phone up for GSM Only.

*#*#INFO#*#* in dialer, then Phone Information
INFO = 4636
Default is GSM/WCDMA Auto (PRL)
Battery History is kinda useful too...

You're right... I tried to force GSM Only and failed.
Not sure why you would ever want to force WCDMA only. The phone will always prefer 3G over 2G.
I tried to force WCMA Only and failed.

The reason for doing that is if you are somewhere on the outer edge of a 3g/4g connection and it keeps jumping back and forth. All the signal jumping can kill a battery quicker.

When you go into the *#*#4636#*#* screen, select phone information and then hit menu. Select radio band and pick AUS. This locks my phone to 3g/4g.

How to Switch Samsung Infuse 4G i997 to 2G Edge Network. Turn off 3G/4G on Samsung In
Warning: This will work depending on where you’re at. If you’re in a good area with excellent coverage your phone may just stay with the H+ and not switch. Here we go.
Step 1) Dial *#*#4636#*#*
Step 2) Click Phone Information (at the top)
Step 3) Scroll down
Step 4) Click the grey/bluish menu and select GSM only. DON’T SELECT ANY OTHER ONES or you may roam on other carriers.
Why would you do this? You can save battery power by not using the H+ network.
_____________________________
To switch back to 3G or 4G
Step 1) To switch back follow steps 1-3 and then click GSM/WCDMA auto (PRL)
It's been good to me but does it work for you?
I remember doing this for a few other phones with good results.
Now I'm doing it with my Sensation and it looks like its working... but I want more people to test it. Test battery drain and data speeds.
Anyways,
Type *#*#4636#*#* in dialer > Phone info > Change WCDMA to GSM auto (PRL) and that is it. You should see the battery drain less on stand by.
post results here... and a thanks would also be good.
if you only use 2g,you can set like that

Yes, it does save battery. Same as going into Mobile Network settings.

GSM Auto (PRL): gives me 4G speeds
GSM only:gives me edge speeds
GSM Auto (PRL) isn't in the mobile network settings.
gsm auto prl will save the user a bit more power because it wont force the phone to continuasly hunt for a stronger signal
And just in case you guys want to play with some settings:
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.
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. (Maybe the Samsung Galaxy S will take advantage of this???)
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

So what's the downside? Edge speed more often? If there was no downside why wouldn't it be the default?
I find gsm auto gives slightly slower speeds in a speedtest than wcdma only... (only two settings I use) and that's it.

Hi there,
I have a Samsung Galaxy S2 LTE (signed with Rogers) and I'm trying to figure out how to disable 4G on my phone and only use 3G. I've looked through some threads talking about changing the "Network mode" in the "Mobile network settings," but I haven't had any luck with that.
GSM/HSPA/LTE (Auto Mode)
GSM/HSPA (Auto Mode)
GSM Only
HSPA Only
Right now, I'm using GSM/HSPA (Auto Mode) but it still says I'm connected to 4G in the status bar. In GSM Only, it connects to the edge network (E) and in HSPA only, it will connect to 4G network. Anyone have any ideas of how to connect using 3G?
Also, I've noticed in my APN settings, I'm using the "ltemobile.apn" (the only APN setting I have listed). I don't have a LTE plan, so should this be the APN that I should be using? Since I'm not on a LTE plan, would I be charged more for using the "ltemobile.apn" APN?
Thanks
4g is 3g/HSPA. If you were able to get LTE, the 4g icon would change (as long as you aren't on a ROM that doesn't have LTE icons)
Is there any way to turn off 4G/LTE completely and just use 3G to conserve battery life? I don't own a Skyrocket but my friend does and has horrible batt life.
On home screen press menu button and go to phone settings
Wireless and Network > Mobile Networks > Network Mode
Here you can tell it to use edge/3g/lte or edge/3g or just edge or just 3g
Hopfully that is not my ROM that allows me to choose that. Using Sky Ice Cream Sandwich rom
It depends on the ROM. Stock won't do it and a number of custom roms I've used don't do it either, but I have seen some that appear to allow for that functionality. Do some research and find one you like.
"4G" is 3g (well hspa+) which is twice as fast as what 3g speeds were originally at (see 4, iphone) its more of a marketing thing. There won't be a 3g icon showing up with these roms. best bet is to choose gsm/hspa then it won't be looking for LTE.

HSPA is actually 3G. AT&T and Tmobile were calling it 4G because they had to come up with some marketing scheme to compete with WiMaxx and LTE. SO in short, AUTO HSPA... is effectively disabling your 4G.
I am using a Galaxy S2 Skyrocket on the Dirty Unicorn rom and I was wondering how I can force my network to 3G. I have Straight Talk on AT&T and a very good LTE 4G signal but it drains my battery very quickly and I don't really need the speed of LTE and the speed of 3G works fine for the things I do.
I've tried in the Mobile Network settings to switch it to GSM/WCDMA preferred but it always immediately switches back to LTE/GSM/WCDMA mode and connects to LTE. The use only 2G networks option does not work either as it immediately gets turned back off as soon as you turn it on.
Using *#*#4636*#*# to switch the mode to WCDMA preferred or GSM preferred does not work either as it also switches back to LTE immediately after.
Is it possible to force the phone to 3G networks? On my old captivate samsung phone on a 4.2 JB rom, it was doable and it worked on 3G fine (even being a 4G enabled phone).
Here is what I've found works on AT&T but it might not work for you.
Go to mobile network settings and then Network Operators. In the Network Operators screen scan for networks. If two different networks appear select the one on the bottom. Then the 2G only button and other settings will work and stick until you reboot your phone. I have to change this every time I reboot. I hope this helps.

Yes. That worked. Now I just need to figure out how to turn off the hspa so it just uses a 3G connection on WCDMA instead of hspa or hspa+

I have been using this technique every time I reboot. Anyone know how to make this permanent?
Or perhaps automate it using tasker?
I want to use 2g only some times i have bad 3g signals in home. There is no option for gsm mode only. It has option of 2g or 3g auto connect i want only 3g
