Hello,
does anyone know which UMTS frequencies HTC Polaris uses?
In the Phone settings are combinations like UMTS2100, UMTS1900+850, ...
See http://forum.xda-developers.com/showthread.php?t=393237
My provider supports UMTS TDD on frequency 872MHz (872-921MHz).
Is any possibility to tweak radio/umts setting for this freq?
Thanks a lot
It would be easier to ask if any1 uses your carrier here and if so has any problems with it or not...
But it should work...
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

Seems that you have changed the frequencies of your mobile network connection.
You may try to change it back to the original frequencies ... if you know the original settings.
If not, you may ask your mobile carrier.
For more detailed help, you have to register on xda and search your device's sepecific forum.
I found some threads about the system menu, you have used to change your mobile network frequencies:

No general solution. You have to check for your specific device how to reset the original settings.
