Motorola Defy US GSM or CDMA ? - Defy General

Okay so, I just debranded my phone rooted and everything. Now I want to know how I'll achieve faster 3G speeds on my phone. Should I leave it at GSM auto ? CDMA auto? or just CDMA or GSM ? Dial *#*#4636#*#* to get there. THANKS in advance!

Could anyone who understands elucidate? I thought in the States T-Mo & AT&T were using GSM, and Verizon and Sprint were on CDMA. Yet, that hidden panel shows the Defy on WCDMA, and the dropdown seems to cover every, it seems, network type (wow, there are many!). Does it mean that the Defy is capable of functioning on any of them? Why is WCDMA selected?

WCDMA is a term used interchangeably with UMTS by some phone manufacturers.
It basically just means '3G'.
The Defy is only compatible with GSM networks, not CDMA.

Unlocked TELUS PRO2 does not work on FIDO 3G network?

I bought HTC PRO2 (RHOD500) from Telus. I just noticed that it does not work on fido 3G network. GSM is fine.
If the Hard-SPL for world phone is released, can I use 3G fido network at that time?
Thanks
You can pay to get it sim unlocked now and it will work. Search for tmobile unlock on ebay. I am on Telus and it works perfect.

I knew that, and my phone has been unlocked. I can make phone call without any problem.
However, I can not use it with fido 3G network.
It does not work at all
Hey,
I don’t think its the phone . I have seen this issue many times in the past All your data settings are still set up for TELUS and the CDMA network, It’s not as simple as just unlocking the SIM card to get the data to work you have to go in an re-program the phone. I would suggest finding the Data setting on a Windows mobile device Fido has and just copying those into you Touch Pro 2. (you will most likely need to do this by hand)
Can’t promise it will work as I know some Carriers have certain fields added and removed to fit their needs which messes up the phone when you unlock it to use on other networks.
Wait!!
does this mean the RHOD500 has GSM and CDMA??
--- Does this mean?
1. Buy Telus TP2
2. Unlock
3. Switch to Fido/Rogers
4. Flash 6.1 GSM rom
5. Use 3g?
I think the issue here is that the Telus TP2 has had the 850/1900MHz UMTS bands disabled for some retarded reason. (Seems especially retarded seeing as how they are rolling out a UMTS network running on those bands in a couple of months).
There is speculation that the bands physically exist on the Telus TP2 but they have been software disabled. The other possibility is that the hardware is not physically present to utilize the 850/1900MHz bands that Fido/Rogers use for their 3G data and that the Telus TP2 will never work on their 3G networks (as well as its own upcoming one) but I think that would be a seriously regretful move on Telus' part.
The spec sheet for the MSM7600 indicates that the phone may or may not be capable of using the 850/1900MHz bands, but according to HTC and Telus' specifications it definitely is able to use the 2100MHz bands (which makes zero sense in Canada since nobody will be using those bands for a long time).

This isn't extremely helpful, but
http://web.archive.org/web/20071025232258/www.cdmatech.com/download_library/pdf/msm7600_chipset.pdf
according to that (if I'm reading right) there has to be at least 1 other UMTS band, no configuration is ONLY 2100MHz (the chipset that does only that doesnt do the 1900MHz PCS band for CDMA). But really, I'm pretty much guessing.
Hi I am using the unlocked Telus version on Fido. It's true that you can't use 3G because the phone does not support the required bands. But I still use EDGE. It's slower but better than nothing. Create a new connection and name it Fido. APN is : internet.fido.ca
Username: fido
PW: fido
Hope this helps.

Go to this site, click on the Details button and you'll see that the TP2 supports all of the above mentioned Bands. The bands are all software locked and once Telus initializes the new network (along with WinMo 6.5) they will offer the firmware upgrade to open ALL the GSM bands. It'll just be the question of unlocking the simlock on the device!

I think that maybe you are confusing GSM bands with the UMTS/HSPA bands.
There's a big difference between the GSM/Edge bands and WCDMA/UMTS.
I have been following the subject and there`s no concrete evidence that the 850/1900 WCDMA/UMTS bands are only software.
Where the hell did you get your firmware upgrade information? I've only seen this info given as pure speculation!
If the TouchPro 1 is any indication, the phone might be missing some key components to make it work. In the case of the TP1 it was the amplifier that was missing so it couldn't work even chipset and everything could support it.
(see: http://forum.xda-developers.com/showthread.php?t=420865&page=40)
So while it's possible, until someone does a teardown of the phone and we see all the required component it's simply not possible to say that 3G on a GSM network is possible.
The ONLY indication I have seen that it might support 850/1900 HSPA network is the fact that telus stated that the Tour and Storm will not work on the HSPA network. They failed to mention the TP2 so maybe we can read between the lines:

I have been following this debate on multiple forums.
Based on some information from RileyFreeman, I do think Telus will enable the TouchPro2 for new HSPA network.
Granted, today, you can unlock and use on Rogers, Fido or ATT networks using EDGE, it would be a real poor move for Telus to not have an upgrade path to HSPA.
This is Telus's non Blackberry flagship business device, today, Telus has Enterprise customers testing the HSPA network (likely either PC cards or USB modems). Once HTC releases Windows Mobile 6.5, this would be an ideal time to upgrade the radio's and unlock the 850/1900 UMTS bands.
I can see the 850/1900 bands today, not 100% if they are actually there, also wondering if Telus is also waiting for ATT to release TP2 so ATT can test ROM, Sprint nor Verizon would not have any need to do any regression testing on ROM that supports UMTS bands. Tell tale sign will be if ATT TP2 has same chipset as Telus TP2.
I am crossing my fingers that TP2 will support Telus Canadian SIM.
I agree with you points. By seing the bands you mean in windows mobile band selction settings? If so these are always there.
I highly doubt ATT will use the same chipset as Telus since they use the MSM7600 to support both GSM and CDMA. ATT as no need for CDMA.
Also to support my claim:
ATT is RHOD300 device.
I think Telus is RHOD500 and Sprint is RHOD400 (can't find this info but I know 400/500 are both world phone, so it might be the opposit or something)
Different RHODXXX indicates differents innards.
Bottom line I want a TP2 with 3G on Fido so Im crossing my finders too!
Edit:
http://www.engadget.com/2009/06/04/atandts-htc-touch-pro2-hits-the-fcc/
So that's Rhodium 100 for T-Mobile, 400/500 for Sprint and Verizon (or vice-versa) and 300 for AT&T
Noob mistake on my part I think the Rhodium XXX is FCC ...so why did I think Telus was in there =\
Sprint is RHOD400, Verizon and Telus both are RHOD500.

WCDMA Desire

I have a desire in Korea running on a WCDMA sim chip on the SK Telecom network. I'm currently in Canada for a while and would like to not have to use roaming. Is it possible to unlock this phone? Are there android 2.2 roms for this phone? If I do this will it disrupt my service with SKT at all? Korea does things a little differently.
I'd head over to the dev forum where you can find a load of unofficial Froyo ROMs.
You can unlock by either paying for an unlock code online and popping that in when using another SIM or flashing the radio which will require root if I'm correct.
Thanks. Whenever I see posts about the desire its always about gsm phones and my sim says its wcdma. Will these roms work?
WCMDA *is* GSM. More correctly WCDMA is a part of the technology used by most GSM networks to implement 3G.
Regard,
Dave

WCDMA and CDMA are not related and completley different.
Dude, you need to go and Google the difference between CDMA and WCDMA or 3G for everyone else out there. Your WCDMA phone is nothing special over the other phones out there
Sent from my HTC Desire using XDA App
WCDMA uses the same system as gsm (uses interchangeable sim cards) but is used on 3g networks running hsdpa because it was found that the old system (tdma) could not cope with the exponential growth of mobile phones and the fact they will consume more of the network's resources. All WCDMA phones are also equipped with old style gsm radio for when there's no 3g coverage. One worry about roaming to north America is that WCDMA uses different frequencies than the rest of the planet but for straightforward phoning and texting and edge you should fine since the 2g bit of the phone is quad band.

[Q] GSM or CDMA Desire?

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.

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?

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.

my phones are HTC desire ADR6275,
android ver 2.2
baseband version (also called radio ver) 2.15.00.09.88

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 ??

[Q] Android GSM Radio

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.

i know this is the wrong section, but the guys in the ATT section aren't as smart as you guys.
i have a motorola atrix from ATT which is gsm, but motorolas web site says phone is ===

and sprint is wcdma so is there a way i can use this phone on sprint, if so what will i need to do ?
No, ATT is a gsm network, sprint is a cdma network. Cannot cross the two.
but specs. says it's dual network, what does that mean ?

WCDMA is the 3G technology used in the US by AT&T and T-Mobile.
WCDMA defined
But the term "CDMA" is also commonly used to refer to one specific family of technologies (IS-95 and CDMA2000) used in the US by Sprint and Verizon Wireless.
CDMA defined

Meaning you could possibly have usage of it overseas, on other gsm carriers on different bands.
You could use the phone on t-mobile because they are gsm, but not sprint, as they're cdma.
ok i knew i'd get the answers i needed in here, thanks guys.
