Turning Off GSM Radio

Hi,
Does anyone have an application to turning off the GSM Radio ? I mean it's only turning off the SIM Card ? I read one topic below, they explained about SIM Status Switcher. But I think that program is too complicated Because I just need a program that only turning off the GSM Radio, not more.
I need this because sometimes when u are on the plane, it's forbidden to turning on your gadget that have radio signal like Handphone, GPS, Wireless Lan etc.
Thanks a lot 8)

Have you tried flight mode? will this do what you require? tap on G icon or signal strength meter and option should pop up. 8)

Try radiooff
see
http://forum.xda-developers.com/viewtopic.php?t=36788&highlight=radiooff

The easiest (and most effective) is simply to tap on the signal meter at the top menu bar, then choose "Flight Mode".
It then displays an "x" on the signal meter, and when you tap on teh signal meter again it tells you "Radio Off" which should be handy to show any nagging flight attendants.

oh I'm so stupid :?
Just tap on the signal meter. Thanks guys.

How to enable Band Selection in Phone Settings?

Does anybody know which registry key to change or make in order to have a Band Tab under Phone Settings?

Band Selection Tab in Phone Settings on HTC Wizard?
Those that have the Band Tab in Phone Settings of WM PPC Phone, would you please do me this favor posting the registry details of this entry: : HKLM\SOFTWARE\OEM\PhoneSetting
My device has ShowTimeZonesPage and ShowPIN2Page only. I wonder if one has got something else. Still working on adding this Band Selection TAB.
Thank you in advance!

I would also appreciate this information. My 8525 keeps latching onto UMTS at a very low signal strength. I'd prefer to disable UMTS at times. Thanks,

Switch between GPRS and UMTS network

Hello,
I know the place in the phone options (on the band page) where you can
change the network from GPRS to UMTS (3G).
But is this possible to do programmatically with RIL or TAPI or another API
on the pocket pc device?
Thanks for any suggestions.

I support this request; Many topics on the board cover erratic behaviour with JJ, and ppl return their device to no avail. Swopping to another operator often helps. The issues SEEMS to be a poor UMTS reception with a given SIM or location, and this results in JJ trying to connect to UMTS or even latching on to UMTS but with an abysmal signal. After more than 15mins (annecdotal) of this is fails to ever go back to GSM without a reboot.
Solution is to turn off UMTS, but that's darned inconvenient cos you OFTEN want 3G speed (mail, RSS, google/surf).
Here's a way forwards; can someone tell us what reg entry gets changed when we select GSM vs UMTS? I will then write a couple of .reg files that can be launched from iLauncher (or whatever). Buzz coule probably write a switching app like he did for BT.

i have the same problem
When i use my Universal at home, there is pretty low level of UMTS/WCDMA signal and full level of standard GSM signal. By default Universal changes between those two sources automaticaly. But in my case, the quality of WCDMA signal is often varying just around critical level. So the result is that Universal changes band to GSM and back. And then again. And again. And... Due this, there is sometimes not possible to make data connection, because Uni is so much occupied by changing bands back and forth...
I would like to find a better solution, than select only GSM manually in phone settings. Especially because i have to unselect it manually every time when leaving home :-(
Is there any way to set treshold value (i expect increase it) for automatic switching between WCDMA and GSM?

I still do not know how to switch from UMTS to GPRS and back
with some API function (or AT command) on the device.
If I get these Infos from someone that would be great.
Then I could write a tool that checks the signal quality
and the network status and if UMTS signal is too low
it will activate GPRS.
I think this can be done with RIL API but have not found
any infos.
Houser

Anything new aobut this umts switch problems??
I do have the same problems, often i am unable to make calls, always when umts is on...
would be happy to hear something,
thomas

Ways to improve phone reception?

I generally have excellent 3G signal around my home but find that within the house it seems to flit between 2 bars of "H" to full-bars "G" to no reception [all in the same room/part of the room!]
At home I would generally have wifi on anyway so want to have better/consistent phone reception esp when on-call.
Someone suggested I could disable 3G/HSDPA at home and use GSM only and this will give me better reception.
I don't understand why this would be?
Is this feasible and is it simple to keep switching back and forth between 2G and 3G or will it require softboots etc?
Thanks

You could call Vodafone and let them talk you into giving them £50 for them to use your internet connection for their traffic?

I take it you've not heard about Vodafone's Sure Signal?
http://www.vodafone.co.uk/suresignal

Anyway, with regards to your question about why using GSM gives a better signal.
If you have it set to auto, and your in a low 3G signal area, the phone will be on GSM, see 3G & switch to it. Then it will lose signal, go back to GSM, and the whole thing repeats over and over.
Setting it to GSM will stop this from happening, and as a result you get a better signal.

I have one sat next to me. Really good piece of kit. Without it, I have no signal at all

I went to an Voda store today and he [also] recommended the 2G method. I live in the centre of Manchester so not a mobile blackspot so Voda guy said SurSignal was not really intended for me [but thanks - I didn't know how it works or the cost]

Is band swithcin straight forward [esp if I want to do it lots - probably mainly for nights I am on call]?
Do I have to restart or softreset everytime or is it just a cae of switching back and forth from within setup?

You don't need to reset the device, quickest way to do it is:
Press network icon on top bar so the menu comes up
Press mobile network icon on right of list (will be either a 3G or G icon with a signal bar)
This brings up Wireless controls menu, press Phone (not the on off on the right, but the actual name)
Scroll right down to the bottom it says Band, press that.
Network Type, change it from Auto to GSM.

Or look for that cab to add band switching to the communications manager.

Thanks guys.
Will try it out and see the effects.
No need for a cab if it as straightforward as hollinshead is describing

Another way to speed this up is to add a start-menu shortcut to a programme in your Windows folder called CMBandswitching.exe.

[REF]/[PRJ] Updated: 7/24 Entering Service Menu / Hidden Setup Menus

Team,
***First off I am not responsible for damaged that occurs to any phones. Make sure you know what you are doing before making changes!!!***
I was having an issue with the mic gain recording distorted live concert audio so I was wondering how to access extended features on the Galaxy S.
The following is the code to dial in to access the hidden Service Mode menus.
Example how to access menus:
Dial *#*#197328640#*#*
This allowed me to adjust the mic gain to get better audio recordings at loud live concerts.
There seems to be several hidden menus on the Galaxy S and I am wondering how many more there are. Which led me to post this thread.
If any of you can find more hidden menus post them and i'll add them to this OP.
So far I know about:
Hidden Menus:
Service Menu: *#*#197328640#*#*
GPS Hidden Menu: *#*#1472365#*#*
Battery and General Info: *#*#4636#*#*
GTalk Service Monitor: *#*#8255#*#*
LCD / Speaker Test: *#0*#
Factory Data Reset: *#*#7780#*#*
Camera Information: *#*#34971539#*#* (Do Not Use The First Option "update camera firmware" you will break your camera)
Change Power Button Action: *#*#7594#*#*
Show IMEI Number: *#06#
Be careful in Service Mode that you know what it is your changing. If you hork up your phone you can reset it by doing a Factory data reset in Settings / Privacy / Factory data reset.
I would do a nandroid backup before making changes if your just experimenting.
I will add reference material below as I can:
__________________________________________________ __
Service Menu:
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}
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. (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.

Dude where you getting all these code. Nice find. You have any more? LOL
I don't which is which. I don't want to mess up anything on it.
Do you know how to work these setup menus?

Updated OP with more codes

I know how to get to the volume service menus in the phone, but does anyone know how to make the earpiece volume louder? My phone is too quiet when up to my ear (rocker volume maxed out) and I don't know what exactly to change in the service menus. I did it on my eternity but this one is a little different. any help is appreciated.

Several there that say RX, which one exactly? And what's the maximum possible value to make the incoming ringtone/text/email notifications louder? Thank you for all this, btw.

could it be that that's because the phone is locked and needs to be unlocked by the carrier

Did we figure out how to max out the volume on incoming calls/texts? Samsung is notoriusly quiet.

I found a code on nother forum but can't remember where.. When entered it asked for a password and an IME number and one other number.. I found it by accident one day when searching for 'unlock captivate' and I think it brings up the same menu that is brought up when you use a foreign sim... Would allow unlock without requiring the insertion of a foreign sim..
Anyone know this code?
