Can anyone show me how to switch to different Radio/Band in Siemens SX66? I couldn't find the place to set in Sx66.
Thanks in advance
How to use SX66 phone outside of USA
I guess my question was not clear. Here is what I need help for. I am planing to use SX66 unlock phone when traveling to China. Do I need to set different radio(900 Mhz or 1800 Mhz whatever number will be in China) or the phone will know the band and set it automatically? I could not find where to set in SX66 phone. Can anyone show me how to do it?
Thanks a lot
You do not have to set it yourself.
The phone will automatically search for networks on any band.

Thank you so much for the reply.
I had no problems with my local gsm carrier which operats on 1800Mhz band until a new carrier arrived in the market operating on 850/1900 (not yet launched but testing). Now very often I only see the 850/1900 carrier, to which I obviously cannot connect, and I cannot see my carrier for long periods in certain locations. My phone then shows, "No service".
At these "no service' times everyone around my is able to see my carrier on their handsets. I have also experienced a version of this in roaming also but it's real problem at home. Seems like the radio searches for 850 or 1900 first and if it finds any a network it stops searching.
Friends with Treo 850s had the same problem but there were able to choose a preferred band. I also recently heard of other users of Windows 2003 devices in my area having the same problems on non-imate handsets.
I have read about newer radio versions like 1.13 and 1.15 but it is not clear to me if there address this problem at all. I also saw a band switching tool but that was for the Wallaby ROM. Has anyone experienced this problem and if so what can I do?
My software stack on my phone is the latest imate PDA2K releases:
ROM version: 1.40.00 WWE
Radio version: 1.12.00
ExtROM version: 1.40.176 WWE

What happens when you do a network search? You might want to try setting your network selection to manual as well since it seems that the new GSM 850/1900 (according to GSMWorld.com it is Digicel) network is causing some kind of reception issues for you.
You are correct about where the interference is coming from. I have tried using manual but my phone begins searching, gives me the option of selecting Digicel (850/1900) but my carrier (1800) is not shown.

Dear colleagues,
I have bought a Diamond in France 1 week ago and tryed to flash its ROM to a quad-band one. My device is hardSPL with diamond-hspl-1.24 and flashed the ROM 1.93.831.1 WWE.
Follow the device information:
ROM version: 1.93.831.1 WWE
ROM date: 07/18/08
Radio Version: 1.00.25.05
Protocol version: 52.29.25.12H
But is still appears at phone settings section to select GSM/UMTS band only:
UMTS (900+2100) + GSM (900+1800)
What could possibly be wrong?
Thanks.
Your radio is a quad-band radio, so you have quad-band now, if it does not show up it maybe because of the ROM that you are using, but if you were to go to a place that uses the 850 band it will pick it up, even if its not shown there, as long as you leave it on auto.
Thanks, but are you sure? Just to confirm. I am not doubting on you.
Which English ROM may I use to show up the settings GSM (850+1900).
Thanks again.
I forgot to say that when I try to make a videocall a message shows up saying that the 3G network is not available. And I am on an area with 850 MHz (State of Minas Gerais, Brazil; operator TIM).

You have a Europe Diamond, it wont work on any Americas network.
You need a US spec Diamond to work on the 850mgz 3G.
Up till know it has almost been confirmed its a Hardware matter.
All diamonds are quad.

If you say all diamonds are quad what is the problem in working in americas networks? Of course with the right rom.

As far as I know ROM has no important effect on Radio. For they are independent. Thats why they are flashed separately.
GSM frequency is one thing and another is the 3G frequency.
Greetings.
to confirm that you have 850mhz gsm which is quadband, goto phone and enter
*#*#364#*#* to launch field test.
now under the BAND section it will say 850 when you are using that frequency. try it when your in a mall or underground somewhere otherwise it will say PCS wich is 1900mhz.
i recommend leaving your phone settings to AUTO.

Ok, your phone have quad band on the GSM network, so you'll be able to use the EDGE, and GPRS data and phone service, while the 3G band on your diamond is Euro spec, so it won't pick up the 850Mhz/1900Mhz band (instead it'll pick up 900/2100mhz band).

That's correct, I didin't realize you were talkink about 3G, you'll not get it with a european diamond.
It's really strange. Me with my two friends have two T-mobile MDA Compact IV from Germany and one O2 XDA Ignito from UK.
In Menu Start-> SERVICES-> BAND-> shown:
1st) T-Mobile Germany was with original 1.37 German ROM, but I put original T-Mobile UK 1.37 ROM WWE. In both ROM's was same info.
"Select your network type"
- Auto
- GSM
(Where is WCDMA?!!!)
"Select your GSM/UMTS band"
- Auto
- UMTS(900+2100)+GSM(900+1800)
- UMTS(850+1900)+GSM(850+1900)
2nd) T-Mobile Germany was with same original 1.37 German ROM, but I put Diamond.ASerg.23.RUS.
"Select your network type"
- Auto
- GSM
- WCDMA
"Select your GSM/UMTS band"

- UMTS(800+2100)
- UMTS(850+2100)+GSM(900+1800)
- UMTS(850)+GSM(900+1800)
- UMTS(1700)
3rd) O2 XDA Ignito from O2 UK (original UK O2 1.93 ROM WWE):
"Select your network type"
- Auto
- GSM
- WCDMA
"Select your GSM/UMTS band"
- Auto
- GSM(900+1800)+UMTS(2100)
- GSM(1900)
Why is the difference in network's shown? Is it means that T-mobile MDA Compact IV (HTC Victor) have different hardware?
Does new ROM affect available network type?

the bands in setting can show any bands all they want, but it will only work if there is the 3G chipset to use it. So even if your phone show 850/1900 on a Euro Spec diamond, it's still not going to work with US 3G. The only reason that it showed them all is probably the rom that you are using have all the known bands to show in setting by editing the registry.

Ok. Thanks. But how can I know the chipset I am using and if it is a 3G chipset? And more, When buying another phone how can I know it works in over 3G in any band?
Another thing: Taking a look in HTC french web page, in "diamond specifications" we can see:
Europe/Asie : 900/2100 MHz, USA : 850/1900 MHz
GSM triband/GPRS/EDGE :
Europe/Asie : 900/1800/1900 MHz, USA : 850/1800/1900 MHz
My Diamond was bought in France.
Sorry ... but I think you are wrong saying that it is any hardware issue or that it won't work. Please see existing threads in Raphael section, it has already been discussed.
As for Diamond !! we are 100% sure that the hardware is fine for all bands (3g and gsm) except WCDMA 800, as the calib data does exist and the hardware itself is capable. All Diamond I have seen so far have an rtr6285 and also the newer radio firmware support all bands except WCDMA 800. If using newer radio doesn't work (quadband enabled), so it is a ROM/SPL issue as it seems or your device needs updated nvitems.
As for Raphael, it is the same, except that this one might have an hardware issue (antenna).
We (me, cmonex and olipro) are working on this issue already. Once we get the diag port running on EU Diamonds, we are sure we can enable it for all bands (except 800 WCDMA).

Woooow give me some hope.
But I was 100% convinced that my euro spec Diamond could never join 850/1900 bands.
Only GSM but not 3G at 850.
Thank you very much!

WAAAAAA i can haz more g's?!?!?
chipset hardware change
any update on enable all band?
Yes. It can't be enabled, it is a hardware issue.
Problem is that for umts 850 there is no power amplifier built in.

I live in the UK, and am using a foreign version of a TP2 that I bought on eBay. I think it's probably the Hong Kong version - it's in English, but with support for Chinese characters on the keyboard.
Something I do fairly regularly is switch between 2G and 3G modes on my TP2 manually. I've created a start-menu short-cut to CMBandSwitching.exe which lets me change the phone's Band setting between "Auto", "GSM" and "WCDMA". My somewhat limited understanding of these settings is that "GSM" basically means "2G", and "WCDMA" basically means "3G". When I set the phone to "GSM" it picks up GPRS or EDGE signals (according to the status bar). When I set it to "WCDMA" it picks up HDSPA or 3G signals (if there are any). What I thought "Auto" mode did was simply switch automatically between 3G and 2G mode depending on 3G signal strength - so that if there's a 3G signal it uses that, if not, it uses 2G.
However, it seems like there may be slightly more to it than that. If I have the phone in GSM mode at home and search for available networks, it finds O2, T-Mobile, Vodafone and Orange (in that order - does that mean O2's signal is the strongest, or does it put it at the top of the list because I have an O2 SIM?) In WCDMA mode it only finds O2, which would suggest that O2 is the only 3G signal that can be picked up in my home (and even that's pretty weak ). However, if I set the phone to Auto, then search for networks, then it also starts to get a signal from the 3 network and lists all 5 carriers - in other words, in Auto mode it finds a signal which is not visible in either GSM or WCDMA mode. This suggests that Auto may be doing something else besides switching between 2G and 3G. Can anyone explain this?
Also, if O2 is the only network it can find when set to "WCDMA" does this mean that O2's is the only 3G signal I can receive?
Finally, there are four possible frequency settings in the lower part of the BandSwitching app. These are:
Auto
GSM(900+1800)+UMTS(900+2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Which is the best setting for UK use? I'm currently using the second one, and it seems to work okay, but would I gain anything by switching it to "Auto"? And can someone give me an idea of which areas in the world I could get decent 2G or 3G reception with that selection of settings available?
(bump)
No one...?
If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.
Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.
This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.
I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?
