I just bought a singapore-configured omnia and i can only get it to connect to edge here despite being in a known 3g network... In the connection manager i only have options for "cellular line" and "cellular line (gprs)" (as well as haynes and bluetooth etc), but no "cellular line (gprs, 3g)" as I do on my other phone...
Any suggestions as to how i might get it to recognize the 3g in my area? (rogers/at&t).
Thanks!
if i'm not mistaken i900 has 3G but only in the 2100 band, maybe you can check with your operator what 3G band they are using...
I believe rogers runs their 3g on 1900 and there is no option for 2100 on the phone, only 850/1900 and 900/1800...

what you are saying is the GSM band, what I meant was the UMTS band which is 2100 for the i780
I have no option for UMTS in the phone ;\ I believe rogers runs on 2100 also but i'd have to check my other phone... is there somewhere where 3g/umts could be disabled on the phone? The specs say that it supports tri-band and umts.
edit: just checked the rogers phone, under settings -> phone i have a seperate tab for "band" wherein i can choose the gms/umts band "gsm(900+1800)+umts(2100)" etc but on the omnia there is nothing of the sort.
is it possible that the korean version of the phone somehow has umts disabled?

try under the MORE tab in phone settings, frequency in BAND SELECTION should be set to automatic.
This is a big mystery to which there is no real answer.
I have a I900 as well, but I do not have 3G/WCDMA in the US via AT&T which uses 850/1900 bands (which I believe is what Rogers and Fido use).
Here are some interesting bits:
- The I907 is a North American version that supports 3G on 850 and 1900.
- No one to my knowledge has seen any different hardware parts related to the Cell in the I907 vs the I900. The radio in both supports 8 of the UMTS bands that have been proposed (only 4 are in common use, and one of those is only in Japan). The cell antenae of the I900 are designed for optimal gain in the 850/1900 bands.
The Radio is idential to that of the Diamond, Touch Pro, G1, Kaiser, Touch, Touch HD and anything else using the 7201A or 7200 chipset. The I900 and I907 do not use this chipset, but it uses the same radio hardware.
No one was able to get the EU Diamond to use the 850/1900 GSM band, and in fact the US Diamond has the same radio Firmware as the EU diamond.
I was confident that if anyone could figure out how to make this work, it would be people at XDA on an HTC device (caveat - there are a lot of europeans here who don't care about 3G in north America, so I may have been wrong there)
Where does it say tri band UMTS on your phone?
I just upped the UK t-mobile rom into the phone and surprise, the profiles for singapore internet are still in the phone... HOW is this possible on a full rom (pda + phone) flash???
anyways, looks like the umts spectrums we use are locked in the firmware for the phone, despite the radio being able to use it ;\

Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.

There are many Roms Available on Modaco
www.
It seems like there are at least four places in which firmware lives:
- "Phone" (usually called Radio)
- "PDA" (the rest of the ROM)
- "CSC" (seems to be for branding. I.e. TMobile has a special .csc file as compared to stock ROMS with similar firmware)
- GSM settings, accessible through dialing obscure number on the Phone. Search Modaco for a list, people seem to find new ones every day. Some of these numbers just effect the ROM settings, but some seems a little more powerful.
- In some of the recent Roms there is a Band Tab in the phone settings, but it only lists "Auto", "850/1900", "900/1800" and "WCDMA". WCDMA is 2100 in the rom I have installed (Signapore PDA with an "Open Market" Phone (XXHI2) )
mine, with the t-mobile rom, only shows 800/1900 as an option in band selection ;\

http://www.sparus-software.com/Devi...yer-Addict/Disable-3G-on-Samsung-Omnia-a.html
Pretty much as the title says, the Hong Kong version would appear to me to be fully enabled for 3g as the freqs are as follows.
Auto
GSM(900+1800)+UMTS(900+2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
I would prefer this version over the tilt but I need my 3g.
You can get Australian version as well (Telstra). That's what I am using, 3g works, and you'll have the fifth row on the keyboard with numbers, although I hard spl'ed and installed WWE 6.5 on it.
The telstra doesnt have 1900 umts though which AT&T uses which makes this seem like a mo betta option. Or am I mistaken?
In my Telstra version's phone band settings, I can see GSM(1900+850)+UMTS(1900+850) option. Normally I keep it at "auto" but I have just selected that, and phone plus 3g data connection still works with AT&T in northern VA.
If there is another way to check it for sure I can do that as well but I don't know where to look else.
Because you see the option in software does not mean it exists in hardware and the same is true with the hk piece. The information I have says the Telstra unit does not support 1900 in hardware. Not sure on the HK unit which lead to this post. I have been trying to figure out if I am on 850 in my local area but AT&T hasnt given me an answer yet. If I was I could probably live with edge here and there on the road.
I have found a map (see link below) that shows 850 and 1900mhz coverage but on the web page it says it is from 2008. All I can say for sure is in VA/MD/DC metro area it is mostly 850Mhz since I did not drop to Edge yet.

Hi all, Firstly iv got a O2 UK branded desire. Iv already rooted it and im now running leedriod2.2 but my problem is I wish to also install the psfMod But im confused at which file I need to download, as the titlle suggests I need to know if its GSM or CDMA or how can I find this out. Thanks in advance.

CDMA has no SIM, GSM does. Your phone is GSM.
Oh so thats the difference lol, I feel silly now. thanks for the reply.

Im almost certain this is wrong.
Its to do with the type of network you operator uses.
Can be found on the HBOOT Screen.
Bravo = GSM
Bravoc = CDMA

Well yes, it's down to the cellular network used, codecs used to transmit the data, different frequency and network structure. But in the most absolute laymans terms, GSM has a removable SIM card and CDMA doesn't.
He wanted to know what file to download for his Desire, not a comparative on the different standards adoped by each technology. So I gave him the most basic answer so he could go ahead and install the program to his phone, makes sense don't you think?

well i have to give u right the CDMA is only operating in
2G Network CDMA 800 / 1900
3G Network CDMA2000
GSM in
2G Network GSM 850 / 900 / 1800 / 1900

4G in
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
here is a little about it
In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs.
The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM. CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful.
Coverage: The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors' coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice.
Data Transfer Speed: With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies
also known as CDMA2000, is CDMA's answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. As of fall 2005, EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready.
GSM's answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275—380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required.
In the case of EVDO, theoretical high traffic can degrade speed and performance, while the EDGE network is more susceptible to interference. Both require being within close range of a cell to get the best speeds, while performance decreases with distance.
Subscriber Identity Module (SIM) cards: In the United States only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carri
The CDMA equivalent, a R-UIM card, is only available in parts of Asia but remains on the horizon for the U.S. market. CDMA carriers in the U.S. require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless.
Roaming: For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher.
International Roaming: If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad, providing it is a quad-band phone (850/900/1800/1900 MHz). By purchasing a SIM card with minutes and a local number in the country you are visiting, you can make calls against the card to save yourself international roaming charges from your carrier back home. CDMA phones that are not card-enabled do not have this capability, however there are several countries that use CDMA networks. Check with your CDMA provider for your specific requirements.
According CDG.org, CDMA networks support over 270 million subscribers worldwide, while GSM.org tallies up their score at over 1 billion. As CDMA phones become R-UIM enabled and roaming contracts between networks improve, integration of the standards might eventually make differences all but transparent to the consumer.
The chief GSM carriers in the United States are Cingular Wireless, recently merged with AT&T Wireless, and T-Mobile USA. Major CDMA carriers are Sprint PCS, Verizon and Virgin Mobile. There are also several smaller cellular companies on both networks.

i dont excute anything
im just pointing out that u are right
an i explaine to the person ho ask fore it
what an how about GSM an CDMA
it has nothing todo whit u or ur answer
In most cases I've seen, GSM are European variants of the device and CDMA are usually US devices.
That is just from my own experience though, so I could be wrong..

o yeah?? how comes mine have sim card slots?
yess the CDMAs ussualy not having sim card slots we must injection the number to the phone, but mine have the slots.
for not trying for making another thread, i also want a help from you guys here.
my phones are HTC desire ADR6275,
android ver 2.2
baseband version (also called radio ver) 2.15.00.09.88
kernel 2..6.32.21-g7a207a4
build number 2.11.573.5 CL325935
PRI version 1.70_027
i have trouble for read and access my SIM card for reading phone book and also having call from my SIM card.
is it because the radio version or the OS version or ??
I am on Wind, a new Canadian 3G AWS only network that defaults to (roams) Rogers GSM when the signal is weak. I have noticed that the sensitivity on WM 6.5 seems to be much more better than on Android in that I can select Wind inside my home in Windows but the Phone will not find Wind as an available network on Android. I have not selected "2G networks only". I would have assumed that the Android build uses the same radio software.
It uses the same radio firmware if that's what you mean. Hardly the same at the software level...
Either way with Android you get a choice - GSM or CDMA. You can't flip between (to my knowledge...) while in the OS as you have to change that value in the startup.txt to get either GSM or CDMA service.
I think there may be a way to adjust startup values on the fly, but it's certainly not straightforward as I recall. I'll see what I can drum up, but that is your problem I believe.
Thanks, some more background: Both networks are GSM, one (Wind) 3G on 1700 and 2100 and the other standard north American 2G GSM (850 and 1900). As far as I know the roaming agreement does not allow my phone to use the 3G part of the Rogers network. The phone is originally t-mobile GSM - otherwise it would not work on Wind.
I really do not think that CDMA comes in to the equation.

Ah, I misread your post. I apologize... not sure what you would need at this point but I'm not sure anyone else is doing what you're trying to do... Hopefully someone who is chimes in
Android GSM Radio
@arrrghhh
I probably did not state it clearly.
I have a t-mobile (US) Touch Pro 2 that is unlocked. When I use it in WM 6.5 at home I get to select the Wind network as an option. When I use the phone in Android mode I do not get to see the Wind network at all but only the Rogers network that Wind roams on as the Rogers network is much larger than the Wind network. Is the problem with less sensitive GSM radio software or are there some selections such as "data enabled" or "2G network only" that I have not made correctly?
I don't believe so, and I've heard GSM reports what service it is getting from the tower ID - so perhaps the towers you're connecting to are still Rogers even tho Wind probably leases tower space from them...
Unfortunately I don't have this ability, and I'm not sure anyone else uses GSM in this manner - I'll poke around and see if I find anything that is useful.
Hi everyone,
Was wondering if anyone was having problems with the following setup:
- Desire HD running Android Revolution HD 5.1.7 (will update later)
- T-Mobile
- 12.54.60.25_26.09.04.11_M2 Radio
Since flashing this radio/upgrading to this version of the Revolution HD rom about 10 days ago I've noticed a huge performance boost from the battery. However I think the radio is causing problems as I'm unable to send/receive MMS messages or have any 3G/HSDPA signal..
I've been over in Canada and noticed I was unable to get 3G speeds and was always stuck on Edge. I put this down to being in another country and Fido said I had the European version of the phone which wasn't compatible with their data network. I was a bit surprised because I figured the phone was compatible with all frequencies (as covered on the Tech Specs page of htc.com)but I'm not sure whether that lists the frequencies for say the "European" version of the phone *and* the "North American" version of the phone..
HSPA Frequencies in Europe (PCS): 900 / 2100
HSPA Frequencies in North America (PCS): 850 / 1900
The Telus DHD and Inspire 4G are the exact same device internally, the only difference is the "AT&T" in chrome on the metal housing rather than "HTC" on it for the Inspire 4G.
Every other DHD will not support north american bands, thats why you're limited to EDGE, since its the highest GSM gets (which supports the north american frequencies since that radio controller is quadband)
Not only that, but apn settings need to be entered for any data to work correctly (even if the frequencies are supported)
The general HTC Webpage shows the European/Asian frequency support of the phone, unless you choose a north american portal (US/Can)

Thanks for the response.
..Just realised I forgot to finish the post! (I'm blaming Jetlag).
..Anyway I got back to the UK on Thursday and have been unable to get 3G/MMS since I returned. I've walked all around the city today and at no point have I got anything other than Edge or GPRS coverage.
I've checked all the APN settings etc and all is fine.
