[q] a way to only run edge and no 3g

Hi, sorry for the seemingly noob question, i've done some searching online but have been unable to find out anything concrete. Is there any way to turn off 3g, and just use edge? Alot of the times i just need email or rss, don't need any crazy fast internet...
thanks in advance!

Settings->Wireless and Network->Mobile networks->Network mode -> GSM

Settings- wireless and network(the topmost) -mobile network (second to last) -network mode-then tick just gsm
Sorry my sgs is german so i had to translate the steps but i hope u know where to look

Thanks alot both of you! really appreciate it!

hi there, thanks again for the help last time, however it seems, now that i have enabled gsm, i can no longer enable 3g..
my only options when i look at network mode are:
gsm/wcdma (auto mode), gsm only, and wcdma only, these are the same as the options i had before, so i don't know why it doesn't connect to 3g now

what firmware are you running? have you updated to something other than a stock Bell ROM? there have been issues with some non-North American-based firmware with enabling the 850MHz band.

im running jpx?
it's darky's 6.0 rom, the weirdest thing is it was working prior to me switching to gsm only
should i just flash back to a bell rom? if so... which rom do you recommend? the eclair or froyo? thanks!

I am running froyo, but I have found that if you are running a non-Bell modem, then using the
Settings > Wireless > Mobile Networks > Network Mode
option to switch between 2G/3G doesn't enable the 850MHz band for 3G.
Recently I have flashed the Bell JK4 modem and don't have this issue any more (but strangely now the 900MHz band doesn't get enabled, but I don't need it here so I'm fine with it).
To check for yourself, assuming you don't have SGS Tools (which you should get if you don't) go into the phone dialer, and dial:
*#2263#
This brings up the band selection option. Then go into
[4] COMBI BANDS
and select
[8] WCDMA 850 ......
Then just back button out of there. You may have to cycle your radio by going into and then out of airplane mode to see the effect faster. Let me know if you then have 3G again.

[Q] HSDPA enable/disable in cm7.2 galaxy mini

I desperately want to know if hsdpa can be on/off in new cyanogenmod 7.2 for galaxy mini because an app in android market named "hidden features free sammy edtn" was successfull in enabling/disabling hsdpa in stock rom but it does not work on cm 7.2 !!!

i dont want to disable 3g network, just want to switch to umts data or hsdpa data as per requirement.. it helps massively saving battery ...
in my case i used the software named "hidden features free sammy edtn" on stock 2.2.1 and switched to release 99(WCDMA DATA ONLY & 3.5G off) then i installed cm7.2, since then im on wcdma data and i cannot switch to hsdpa data... so i need an option to change 3g data DEVELOPERS HELP

I don't know how this will help.
*#*#4636#*#*
In phone info u can choose the preferred network.
Heard gsm auto prl saves battery.

HSDPA is nothing simply some improved version of 3G or similar network... If you don't use mobile data packet, i.e. 3G/2G or any means of connection via sim card then HSDPA is already disabled.

yagya ill explain what im trying to say:
1: if i type *#301279# (HSDPA/HSUPA Control Menu) on stock rom i can disable hsdpa and 3g radio works as R99 mode (UMTS data only, hsdpa off, 3.0G)
2: i try to do the same on cm 7.2, nothing happens,, i dont get a menu
3: i tried appending ro.ril.hsxpa=0 to system.prop in /system using root explorer,,, after many restarts it doesnt work either,,,
u see the problem here is im subscribed to tata docomo 3g network here in india, the 3g data plans are sky high and very much unaffordable.. so im in 2g data plan : luckily my operator allows me to use 3g network but with speed limited to 18kBps because of 2g plan subscription..... so all the time using 3.5G with hsdpa for just 18kBps is useless + its a battery eater even for just chatting !

use the. notification power widget function. it's in cyanogenmod setting.
there's a toggle to change 2G or 3G network.

u see, 3g network mode always does not always imply hsdpa mode to be used.. i want to configure the 3g radio to use only umts packet data(3.0G) and to switch off hsdpa(3.5G) packet data service WHILE USING 3G network all the time... a stock rom can do it, why can't cyanogenmod???
>> an app in android market named "hidden features free sammy edtn" was successfull in enabling/disabling hsdpa in stock rom but it does not work on cm 7.2rc3 !!!
>> *#301279# (HSDPA/HSUPA Control Menu) on stock rom i can disable hsdpa and 3g radio works as R99 mode (UMTS data only, hsdpa off, 3.0G) but this code doesnt work on cm7.2rc3

maybe that is the lack from cm7, don't use it if it won't satisfy u.

Forcing 4G/LTE off to save battery

Using the Telstra based roms, I can turn 4G/LTE off and my battery easily gets me through the day, with 4G on, I have to recharge by 1pm.
On at&t based roms, there is no way to turn off 4G/LTE when you are in Australia, as all of Telstra's APN's support 4G/LTE, there is no apn you can select which disables 4G/LTE, in the Telstra roms there is an option under settings > Mobile Network which allows you to select 3G only, *#*#4636#*#* forcing to wcdma works but doesn't stick.
is there a mod that could disable the 4G/LTE modem or is this something that needs to be cooked into the ROM?
Maybe I could just kill the 4G/LTE modem "device" via a script in the console?

Get a non LTE enabled simcard, or use hdspa apns and delete the LTE apns, this will disable lte.

Why, especially when the carrier Tel$tra doesnt do non
LTE apns
Stock ROM from this carrier gives the option to just switch it off
Surely this can be cooked into other ROM's

in Australia, all SIM cards from telstra allow for 4G/LTE and all APN's use 4G, the only "odd" sim cards are the iphone ones or the ones that were 2G only, the only way to force LTE to stay off that I am aware of is either using the MIUI rom that doesnt have an 4g/LTE modem driver and so wins by failing, or using a ROM based on the Telstra rom which has an easy switch to turn off 4G/LTE

4g/lte modem driver? 3g/lte is handle by one single modem module...

I'm no ROM developer, I don't know the first thing about the internal devily going on inside a handset, I am only aware that the MIUI ROM is incapable of 4G which to me would point to some difference in the drivers or config, whatever.
The Telstra ROM can turn 4G off, the MIUI rom doesn't have 4G and the at&t rom defaults to LTE as much as you fight it in Australia.
Now that everyone is done poking holes in my knowledge, does anyone have anything constructive to add or should I just give up

i have mine set to GSM auto.
what does that mean? i want to save battery

where do you have that set, under *#*#4636#*#* ?

makes me wonder why more devs dont use the telstra rom as a base switchable lte tethering built in higher clock speed seems to be a better base?

Where is network mode choice for 3g/2g auto switch

I use rom Pure Nexus rom and have only 2g 3g and Lte option in seperately. Pls someone advise wherever or any rom have option for auto switch network like 3g priotiy then weak signal will switch to 2g
Tks so much

the phone will do this automatically in either setting, just leave it on lte and it will have the better tech whenever it finds it and if it looses it it will switch to the lower one within specified thresholds. i know it will switch to 3g from LTE at -120dbm but i dont know what the threshold is for 3g-2g
