sorry for my English, I can not stop the network in 2G or GSM, mobile networks in the options there are only 4g / 3g / 2g, 3g / 2g, 3g only. Does anyone know how to block 2g gsm?
Try this. Go into Dialer and hit *#*#4636#*#*
Then go to Phone Information and scroll down to network type. Set it to LTE only and see if it holds the setting.

my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to and looking for hsdpa back and forth and drain battery much faster
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda ) data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and drain my battery fast
so... i look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA
is there any tweak/program/widget/application that can enable 3g (umts) only?
i think it is settings>wireless networks> network mode> GSM
if not try *#*#4636#*#*
go to phone information and you can select preferred network type.
If this helps press thanks!
uhh i have tried that before (and choose wcdma only aka 3g only).. and no luck
reason like i sadi before android "thinks" 3g/umts and 3.5/hspda as the same, android categorize umts and hspda as one big fat 3G network...
so 3G in android is umts+hsdpa, while i want umts only
To get 3G UMTS only
Firstly make sure your device is rooted.
Download Root Explorer, if you don't have
Go to your system folder
Mount it as read and write (r/w)
Find Build.prop
Select and Hold it, and the options will appear
Select the open with button
Select the text editor
Scroll down to find ro.ril.hsxpa=1
Change the number to your desire network (0 or 5 = UMTS , 1 = HSDPA only, 2 = HSDPA & HSUPA)
For your case change it to 5 and it should be like this ro.ril.hsxpa=5
Save it
Then reboot
Now it should be running 3G instead of H
This worked for my HTC Desire HD
don't work for me.
In ro.ril.hsxpa=X, I have written x=0 and I'm still leaving a H

I'm noticing most of us are on the AT&T Network, yet there are those that do not want or need 3G/3.5G and want to use 2G or have another carrier so they cant take advantage of the speeds because they are on a Network such as T-Mobile.
Obviously someone using primarily or mainly 2G will see significantly more battery life.
This is good for someone that rarely uses data service or goes online using WIFI for the most part.
To change or edit your Preferred Network type go to your Phone app
then enter the following: *#*#4636#*#*
>Phone Information
>Set Preferred Network Type
Now you are able to change and edit the way your phone looks for and uses the Network you are currently on.
The Terms are explained below:
Preferred Network Types change the type of frequency the phone searches for.
Android is used on several devices that can gain access to different cell carriers.
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
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.
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
When using the 'only' options you should still be able to make calls.
To put things into perspective, The Nexus One is set to WCDMA preferred as default and the Droid Incredible is set to CDMA auto (PRL).
My Samsun S does not recognise my sim.The sim works in another phone. I tried to change the preferred networkto CDMA preferred, as it is on "unknown". It does not allow me to change it. Please help, as this new phone is now doorstopper.

This option has not worked on any Sense ROM I have tried for the HTC Inspire. It works great on CM7 but does nothing but stay on 3G on sense.
For sense Rom if you are rooted this is how you do it
From today screen
1. Hit menu
2. Click settings
3. Click wireless and networks
4. Scroll down to mobile networks
5. Choose network mode
6. Change to gsm
This will lock you into edge only. Even after reboot settings will stay phone must be rooted or it does not hold settings
If you want 3g/4g only. Set tab to wcdma only
I am running coredroid 9.4

I have tried this on CoreDroid and ARHD and no luck. Went through settings menu and used the *#*#4636#*#* options and neither one sticks. Could it be my radio and hboot and the interface with Sense?
EDIT: Going to try ARHD again and see. If not, I will try CoreDroid.
EDIT: Still a no go for either ROM...ClearDroid included. So far, I have only been able to do this via either method (plus a built in toggle) via CM7. This begs the question of whether this is a software issue with HTC Sense.
Strange I remember when I was on stock sense Rom the settings wouldn't stick. But as soon as I rooted and downloaded a custom Rom it did stick sorry you are having trouble. Here is my complete rom/radio/kernal
Coredroid 9.4 = Rom
12.56.60.25u_26.10.04.03m=radio
Lordmod 5.0 is the kernal
I also changed my build.prop settings to enable real 4g and tweaked gsm gprs umits huspa hsdpa I do not know if this had any effect on making settings stick

Thank you for the feedback. I am running the same radio. I will revisit CoreDroid again. Perhaps editing the build prop is the way to go in this case. It is the one thing I have not tried on any of the ROMs for this phone other than to rename my phone from Desire HD to Inspire (which was only on one or two ROMS). Would you mind sharing your build.prop settings and tweaks so that I can have a baseline to work with? I'll tweak from there as necessary to meet my wants.
I edited only these in build.prop
ro.ril.gprsclass=10
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=7
ro.ril.hsxpa=2
Reboot twice and don't forget to backup your settings
I used prop editor to edit build.prop its easier but I don't have a link for it but I think there is a link in that thread I posted below

Thanks. I will give this a shot. I have edited the build.prop before but only for the purpose of changing device id name. I don't remember what I used to edit it but I am sure I can find it again. No worries about the backups. I kept copies of original build.prop saved plus did a nandroid right before making the changes. Never can be too careful. Will post results later tonight on whether this was success or not for locking in the ability to switch between bands.
In that thread I posted is the build.prop app 8th or 9th post down. That tweak is just for faster data speeds and I do not think it will lock u on to 2 g or 3g but who knows

No go for 2g/3g options. Have not been able to really say about faster data speeds but definitely something I will keep notes on. Back to where I started. Looks like CM will remain my ROM of choice for now.
Preferred network type set to unknown
Hi frnds.. i had accidently set preferred network type to unknown by going in secret setting by using the code *#*#4636#*#* in my Micromax A54 and now my real imei number is changed into 00000000. My mobile is not recognizing any sim and on notification bar it says ''searching for service''. I am not able to reset previous setting i.e. unknown to gsm auto(prl) or gsm only or wcdma only. Please help me how can i resolve my problem.
Your help will be appreciated. thnx in advance..
hi i have samsung note2 my network show unknow but every thing is ok call sms is fine how to i fix it to my network when i restart it they show gprs but when i call some one they going to unknow
Turns out the device has two SIM card slots - one strictly for GSM, another with WCDMA support. If this is the same for you, change SIMcard slot and the preferred network type will change

Hi, here's a tutorial on how to change network modes using AT commands: http://www.josemauricio.net/?p=486
When i try to change my network it automatic changes to wcdma preferred.
When i try to change my network it automatic changes to wcdma preferred
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#*#*

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.

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?
All Sense Roms that I have come across Do not let you Switch between 4G/3G to 2G, This is only possible as far as im concerned on CM or MIUI (Like when you go to Wireless settings>Mobile Networks>2G only) has anybody found a solution to this???
You can, its just worded differently. Go to settings, wireless, mobile network settings, netowrk type and select GSM. GSM/wcdma auto is automatic switching, wcdma is 3g only, GSM is 2g.

Hello guys, i am from India. Here, I have activated airtel 3g and i am from Maharashtra state. Here, airtel network uses IDEA network for 3g packs as they don't own the spectrum. I kept my cell in 3g mode and "automatically select network", but it stays in 2g(Same doesnt happen in my note 2, using 3g in auto mode). If i manually select IDEA from the list of networks, it goes to 3g. I want to keep it on auto, like switch to 2g when 3g is not available. Settings are same. How to make it switch to 3g automatically. Preferred mode is 3g. Any problem in my handset?
Thanks
