Hello. I'm new here.
My handheld is innos i6c which has cdma-gsm. My handheld's data connection was locked to cdma (Hybrid / 1x only / EVDO only).
The "GSM Network Preferences" on setting was hidden, only "CDMA Network Preferences" was shown.
My handheld was rooted. Is there any script on init-d or build.prop or another way to show the "GSM Network Preferences" setting so i can change the GSM Network Preferences to 3G?
BUMP!!!

I need some help modifying a Froyo rom to include a "GSM only" setting.
The background is that under certain conditions (i.e. intermittently), the cell radio shows full connection, but will not allow calls, incoming or outgoing. I finally narrowed a workable solution down to forcing "GSM only" (vs. auto selection of CDMA and GSM networks). But I can only get there at the moment by adding the "Phone info" custom shortcut to my home screen (ADW Launcher) and going in and setting it manually. And unfortunately that doesn't always survive a reboot either.
I would like to simply pre-set that in the rom and not have to re-set it again. I had assumed it was something that could be done in one of the init or prop file, but I have thus far not been successful in finding information about where and how to do that.
Any help would be appreciated.
Solved. For anyone else who stumbles upon this question, the setting in build.prop is:
ro.telephony.default_network=#
Where the # is a number code for which setting you want. In my experimentation for my device, "ro.telephony.default_network=0" is WCDMA preferred and ro.telephony.default_network=1 is GSM only.
I "think" the other codes are as follows (but I can not confirm this):
0 WCDMA preferred
1 GSM only
2 WCDMA only
3 GSM auto (PRL)
4 CDMA auto (PRL)
5 CDMA only
6 EvDo only
7 GSM/CDMA auto (PRL)
8 Unknown
Additionally, if you want to set it temporarily while the phone is running, you can launch the phone info settings by entering this on your phone's keypad:
*#*#4636#*#*
But I believe it will revert to whatever you have in build.prop at the next reboot. No matter what you set in build.prop, you can still go into your Wireless & network settings, Mobile networks, and click on or off the "Use only 2G networks" setting.
So I finally jumped in and got the WanHu ROM installed with M's v5 patch. This thing is really nice now, hopefully it will stay that way even after I reinstall some of my apps.
One thing that I've noticed is that the ability to use only 2G networks is gone. It used to be an option under Settings » Wireless controls » Mobile networks. Any chance that may be coming back?
I know some people would probably think I'm crazy to be asking that, but in my experience the batter life was pretty much double that of what I was getting on 3G, so I'd use that mode sometimes.
Thanks for all the good work on the WanHu ROM.
You can turn off the 3g at Settings >> Wireless networks >> Data Network settings & there is also a 3g widget.
Hi,
At this point you only turn data on or off. You cannot switch from 3g to 2g.
I would like to have this feature to, because the radio at my work is very poor and the battery last much longer in 2g.
Sent from my XT720 using XDA App
switch 2g , 3g, and 2g/3g
if i have to change the default network setting (3, which mean 3g/2g auto), i can from here:
1. from the dialpad dial *#*#4636#*#*
2. from the popued menu, choose Phone Information
3. from "Set preffered network type" You can choose several options including:
"GSM auto (PRL)" (this is usually default and means 3g and failback to 2g, depending on signal
"WCDMA prefered" (this mean 3g and if there is no 3g, then 2g), this settings seems to wotk, but if you exit and return to the same menu it is changed
"WCDMA only" 3g only
"GMS only" 2g only
hope that helps.
p.s. I use Battery monitor application, which has shortcut to the Phone Information menu.

Thanks for the reply. I was messing around in those menus and could not find a "GSM only" mode on my phone. I will look again, but all I remember were an "auto" mode, a "3g only" mode, and a bunch of CDMA stuff (which doesn't apply to our phones).
But I will look again and try out the battery monitor application program as that would be nicer than typing the key sequence everytime.
And just to expand my (rather small) knowledge of the android OS. The option to select only 2G under Settings » Wireless controls » Mobile networks, is that a framework thing that has to be added?

Hello,
I am Uresh and have Lenevo A850 with android 4.2.2 Installed.
I have issue with data connecion.I have 3g plan in my operator.
When i start internet it automatically take GSM mode.
I want to change it to CDMA/WCDMA mode.
Settings - > All Settings -> More ... -> Mobile Networks -> " Network Mode" is Disabled.
Please advice something or solution ,what to do for that ?
3G Network: WCDMA 900/2100MHz (AP/EAST/MEA), 850/1900MHz (LA)
2G Network: GSM 900/1800/1900MHz (AP/EAST/MEA), 850/1800/1900MHz (LA)
Speed: HSPA+ 21Mbps (DL) / 5.76Mbps (UL)/ EDGE
dial *#*#4636#*#* in the dialer n select "phone info" in the popup menu n change gsm to wcdma only
What I am trying to do is have ONLY 3G connection manually, to do this i added a tile in notification bar for 2G to 2G/3G switch, so when i select 2G|3G mode it connects to 3G but after some time it automatically selects 2G (because its 2G|3G, either strong one i guess).
I have also tried selected 3G in network settings, selecting LTE(recommended) also doesn't work.
But I want to be it in 3G mode exclusively even though 2G signal is better.
I have a rooted OPO and can install xposed too, any solution for this will be really helpful !!
Hi
Think you can do this by "dailing" the string *#*#4636#*#* in the dialer app, to bring up the Testing menu. Press "Phone information", then scroll down to "Set prefered network type", there is an option for "WCDMA only".

Perfect.. that exactly what i was looking for !! Thanks..!!
Hi,
On my old Sony, I had something like "LTE/WCDMA/GSM" mode, so phone could successfully fall back to GSM when 3g/4g connection is weak.
Is there such an option for Pixel 3?
I've tried various settings from 4636 menu, but it looks like there is no such option. Even in "GSM auto (PRL)" or "Global auto" is still uses UMTS with -100...-110 dbm signal strength, while in "GSM only" there is -89dbm available.
Is there a settings or some adjustable through adb option, which allows GSM fallback?
I also could write an android app, in order to switch into GSM in some circumstances, if possible.
I've located in the eastern europe, if that matters, and LTE/WCDMA work best on my network, except in my office location.
