GSM Frequeny

I have a Orange SIM card which I got in Israel, I am now in Canada and that SIM works fine on my friends Nokia 6600, but when I try to use it with my XDA IIs I can't find any networks or anything. I am guessing its the GSM frequecy although the phone supports all of them. Does anyone have any idea what I need to do to get the SIM to work here? Does anyone know how to manually select a GSM frequency?
XDA IIs
ROM Version: 1.40.00 WWE
Radio Version: 1.15.00
Protocol Version: 1337.45

Hello psytech,
I believe you're roaming. Sometimes, you really cannot just plug your sim card then voila its working. If you are roaming, most of the time you really have to manually select the network.
anyway, i'm currently using windows mobile 2005, and no longer using windows mobile 2003 SE. i hope i could still help you or atleast you can see the pattern on how to do it.
here what you do:
1. click on the signal strength icon (the icon located on the upper right most portion of your screen just beside the speaker icon)
2. a dialogue box will appear with a clickable 'settings' button (located on lower left part of the dialogue box.), click the 'settings'
3. you will then see 3 tabs on the bottom part of the screen, 'phone', 'services', 'network'. click on 'network'.
4. you should find something like 'find network' button there, then just but before you click on it, choose 'manual' for network selection.
the rest is self explanatory, i hope i was able to help you. cheers!

You say your orange sim works fine on your friends nokia but does not work in your IIs.
Is it possible that your IIS device is sim locked as in will only work on the O2 network in the country you got it from.
If so unlock it via wiki (link in sig)

not it
I forgot to mention that the SIM worked fine in Isreal, my original SIM is orange (I do have an account with) I just can't get support cause I didn't buy the phone from them (capitalists).
About the network search. Thats what I've been doing for the last couple of days but I can not find ANY networks at all. which is what leads me to believe that its a GSM frequency problem.

What happens if you put your friends sim in your phone
GSM in Canada is generally 1900 http://www.gsmworld.com/roaming/gsminfo/cou_ca.shtml

doesn't work either
My friend's SIM doesn't work on my phone either. If canada is 1900, how can I make sure that my phone is currently using 1900. (I know it supports it, but how do I actually see that its actually scanning with it?)

What happens if you go to Settings->Phone->Network and then change Network Selection to Manual.
You should then get a list of networks. This will list all networks even if you cannot connect to them.
[edit] This has already be suggested earlier in the thread
If you do get some networks then the only reason that I can think of that you are not connecting is that under Prefered Networks you have a network selected that your carrier does not have a roaming agreement with.
Check your provider's website to see who they have agreements with.

no networks
My provider (Orange) has agreements with Rodgers, but my problem is that I am not listing ANY networks, I tried manual and even added the Rodgers network to my favorite networks, but when I try to search for networks I can't find any, I just get a blank window. This is very odd to me and I've never heard of anyone with that problem.
Like I've mentioned before, I updated my windows to TuMa 1.4 and my radio to 1.1.15. If there's anything else I need to do or anything I may not have done when I updated my network please tell me.
btw when I installed that TuMa windows I change my ID thingy to Tmobile.

Problem solved
Attenttion everyone:
It has come to my attention that there is a problem in the Band Selection CAB when it comes to certian cellular providers.
The problem so far appears on a Cellular One network that only supports 850Mhz. When the North American Option is choosen in the Band tab, the phone can not find a network to register on. I'm not quite sure why this happens yet, but there is a solution to fix.
http://relaysgoldens.com/sx66/ext_roms/BandSelect-fix.CAB
By installing this CAB, it provides a fourth option on the band tab, "Reset Value to Zero".
By selecting this option, the phone will be reset to it's default state, and will work normally.
I've trapped this as a bug in the 1.40.124 extrom and will be working to figure this out.
Note: the band selection setting is persistant, and will not be reset even if you downgrade the ROMs on the phone. If you are experiencing this problem, the ONLY way to reset the value is to use the CAB above.
-Chris
P.S. I've also updated the 1.40.124 RAR file on the website to include the updated bandselect CAB.

MDA Pro German unlocked; UMTS still only works with T-Mobile

Hello,
thanks to buzzdev's great tool (you are the greatest!) my MDA Pro German now accepts all SIM cards. However, with every SIM card I tried (Eplus/BASE, o2 with UMTS enabled) I never get access to UMTS, even in the center of my town. With the T-Mobile SIM however, UMTS works immediately. Has anybody else experienced this problem? I also tried to hard reset and skip the customization.
Greetings from Bonn, Germany
Andreas

i also have bought a german mda pro and unlocked it. i am using it in austria and umts works correctly.

Maybe you should check if the other providers:
- supports UMTS
- your connection settings are right
- you need a special account to use UMTS
- UMTS is available in your area with that provider
If T-Mobile enabes UMTS for you doesn't mean all providers do.

Yes, I ordered the UMTS option which caused all my SIM-Cards to be replaced by USIMs. The town I live in is medium-sized (300,000 inhabitants), and I checked about eight places - no success. (Typically, UMTS is available in every German town which has about 50,000 inhabitants or more)
What happenes is quite weird: When I switch the phone on, enter my PIN and connect to the network, the UMTS Symbol ("U") appears for about one or two seconds. Then it disappears, the connection gets lost, and the phone reconnects by GSM. It seems that the phone (or the provider?) throws me out just after a successfull UMTS connect.
I also verified that the GPRS/3G connection is set up correctly (APN surfo2, no username and password).
Greetings,
Andreas

you probably already have checked the radio band settings, but its worth a try. have you enabled umts band in telefon - einstellungen?

Yes, UMTS is not disabled; I also tried "WCDMA only", but then no connection can be established.

hmmm, have you tried a hardreset and/or a new/different rom?

Yes, I thought that maybe there was some stupid locking in the T-Mobile GER ROM, so I used the latest Qtek German ROM, I also tried the O2 XDA Exec Launch ROM (UK), but nothing changed.

Are you sure there should be no username/password ? http://www.taniwha.org.uk/gprs.html suggests that it should be guest/guest.

Yes, the website you mentioned is a bit outdated. The official o2 Website (Germany) http://www.o2online.de/o2/kunden/technikundeinst/umts/tools/manuell/index.html states that username/password are "nicht notwendig" (=not necessary).

Ah well, I thought it was worth a mention.
Good luck

i guess the question for another radio rom is obsolete.
so i think your last solution is to get a contract with tmobile j/k

Cingular 8525 / WM6 / UMTS not working

All:
I just got a Cingular 8525 and immediately upgraded it to WM6 (it had WM5 on it for about an hour). I am in a 3g covered area but I do not think I am getting a 3g connection on the phone. I have the big upper case U in a box, and then I have the signal indicator with an E over it. This makes me believe that I am connected to Cingular's edge network. Also, if I am on the phone and I try to run a sync with activesync the phone tells me that I have a voice call in progress. Any suggestions? AT&T support was clueless.

The U indicator is UMTS - that is 3G. However, most of the newer ROMs replace it with a 3G icon. What ROM did you use? Anyway, also, you may try the reg tweak to enable the BAND tab in the Settings > Phone menu. You can find that tweak in the wiki.

I have the same thing with my rogers phone, what I'm guessing is the phone is designed to pick whatever signal is strongest, (which is usually Edge) and not often-rescan for UTMS/3G.
If you google and download Band Switcher, you can force UTMS/3G at your leisure.

I wasnt aware the USA had 3G yet? I was always told that Edge was the best they had out there from a few mobile operators in the UK.
What Radio stack are you using?

Cingular, now known as "The New AT&T (AT&T)" has 3G up and running in some of it's markets.

No one seems to be answering this question.

Is it really possible to make a Diamond quad-band?

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.

(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.

- UMTS(850+2100)+GSM(900+1800)
- UMTS(850)+GSM(900+1800)

3rd) O2 XDA Ignito from O2 UK (original UK O2 1.93 ROM WWE):

"Select your GSM/UMTS band"
- Auto
- GSM(900+1800)+UMTS(2100)

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).

How to re-enable GPRS for HTC Twin1000 (T5399)?

Hi, guys,
I got a HTC T5399 which is said to be Twin 10000, this dual mode phone is on the China market, customized for China Telecom CDMA2000 network, although it also supports WCDMA at the same time according to its brochure.
My problem is that GPRS functionality is disabled deliberately by the manufacturer when I want to use it under WCDMA network with my UK O2 sim card. Of course the voice calls are fine under WCDMA as it's supposed to. When I attempted to establish a new Internet connection, the options of line types are only three types: cellular line, bluetooth and Hayes modem on com port, there is no option of GPRS cellular line available as normal WCDMA 3G phones do. I tried to set up the connection with cellular line anyway but failed to connect to the network.
After googling on the Internet without any progress, I finally have to come here for help, as this website is for the best WM experts in the world. If I can not get it solved with your guys help, I don't think it's possible to sort it out anywhere else.
Thank you very much in advance for your kind support!

Sorry, forgot to let you know, the above device OS is WM6.5, details are
Windows CE 5.2.21869 (Internal version 21869.5.0.82)

Desperately awaiting feedback.....

no solution???

sadly, no one knows?
