I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?
idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry
I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix
It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.
This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.
T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.
Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different
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.
I'm a little green when it comes to 3G stuff, but please correct me if I am wrong...
Yes, you can put foreign SIM cards in US TP2's but not get 3G coverage in Europe. On the other hand from what I have read, European TP2's (even the unbranded ones) will not work with 3G is the US.
And if I am wrong... can someone please point me to a TP2 that will work on 3G networks in most of the world?
Or does one have to have two TP2's to enjoy 3G.. one for the US, and one for Europe, etc.?

Where have you heard that a NA TP2 won't work with 3G in EU?
The only limitation I'm aware of is a NA TP2 won't work w/ NA GSM 3G.

Until someone hacks it
I can't remember where I read it. But someone said if you wanted 3G in Europe, better to get a Euro unbranded model.
So perhaps this is under the assumption that it isn't hacked... not sure.
Slightly, off-topic Q but rather than start a new thread.... once a HardSPL is out for both the CDMA and GSM TP2's... will they effectively be "equal" devoces?
I really would like to pick-up a TP2 in the next few days... I like the VZ unit, but it's CDMA and since I travel quite a bit, really prefer and need more of a GSM phone, but don't like the TMO as no 3.5mm jack.

The Verizon unit already has international GSM bands unlocked, AND international (2100MHz 3G). If you've been a Verizon customer for 60 days or more you can call them up and get an unlock code for free and use any SIM card in your phone so you can get a cheap prepaid SIM and not pay the high Verizon roaming costs. There's also a small (I'd say around 25%) chance that the NA 3G bands will be found/unlocked, but at this point who really knows if they are there or not.
Actually the Telus CDMA TP2 supports the European 3G bands but not the American ones becuase technically you will be using it in North America on CDMA and outside America on GSM. So its the other way around
It seems that if you have the Sprint TP2 that it won't register at all on US GSM networks, but comes unlocked by default.
On Verizon (which I have) a simple phone call to support they'll give you the unlock code and you're good to go. I use an Orange (UK) Sim in mine just fine in the US and others in other forums have reported that using US SIM's from TMobile/AT&T work fine also in the US.

I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings.
Just have to make sure that your provider gives you a 3G SIM (most of them are these days) and that you have the 3G service enabled on your account in the respective country.
Many people say they can't pick it up yet don't have it on their account, or think that their EU provider will automatically provide it as part of the roaming service... which is not a good assumption to make.

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??
Man, this is all confusing... I swear somebody has to come up with an HTML table of what phones work with what and where and stickify it.
Can people just put this to bed already!!!
The Sprint (North America) TP2 is suppossed to be used on CDMA in the US and GSM worldwide, hence the GSM radio is unlocked for outside America GSM use. This is how it comes default. If that is so hard to grasp, then there is no hope for some, sadly.
As for the title, the TP2 is a world phone, it works in the US (and North Ameria) on CDMA and elsewhere unlocked on GSM. That to me is the true definition of a World phone from a U.S CDMA perspective (and especially moreso as this is the CDMA version).
To put it in perspective, a Sprint customer (in this case, moi) gets the best of CDMA in the U.S and when traveling to visit his sister in High Wycombe in the U.K (like i'll be doing this Autumm) gets to pop in a PAYG U.K sim in the same phone and use it while over there. This phone doesn't get any "worldlier" to me than this scenario!!
Is the O.P attempting to specifically define a dual mode CDMA/GSM-unlocked World phone as not world phone because it's locked by default from doing GSM in it's primary market which happens to be CDMA (and in this case Sprint)?
This is not rocket science folks, it really isn't.

Point taken. It's just that with that same Sprint phone (correct me if I am wrong), you can't travel to Canada pop in a Rogers SIM card and get Rogers 3G.
Wouldn't the phone want to swing towards it's CDMA cousin, Telus or Bell?

AT&T 3G runs on 850/1900 GSM, the TP2 supports both of those bands, how would it not work with 3G on AT&T in the US?
T-Mobile runs 3G on 1700/2100 GSM bands, both of which aren't included on the TP2, as far as my research has lead me to believe.
Basically while it may be a quad band GSM phone, it is only a dual band 3G device. It comes in two flavours - UMTS 900+2100 or UMTS 1900+850
The 900/2100 version is far more common than 850/1900

"it Depends"
The US CDMA phone operates in 3 modes.
1 CDMA Only
2 GSM Only
3 'Global' (whatever it can find).
If you have it in Global it will generally take the CDMA local carrier over anything else. However, not always. I've had mine switch to GSM for a bit then go back to CDMA. But mine is Verizon and unlocked so it works everywhere in the US and I also have a UK sim card in it. So I'm a little 'different'.
But, in any case, you can tell the phone which mode to use if you want. All upto you.

(verizon TP2)
here we go again... (tp2 3g na)
"I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings."
So, maybe he's wrong. But either way...
You wanna know why this keeps coming up again and again?
(not because we're all dumb and thick headed, which we may very well be)
But,
Because we just have trouble imagining them hardware "band amplifier" hobbling the hardware when it's so much easier to do it somewhere in firmware.
We all know that the less you fiddle with the hardware for multi-region functionality the less you have to fiddle with the production line and fiddling with the production line is the Last Thing a manufacturer wants to do.
Someone even once said that there wasn't room in the Rhodium platform for quad band data support. But now we're expecting the tilt 2 to do just that.
So, all protestations aside, those of us who paid ~700 us clams for this beauty, and who like the kbd layout.
And who have like me (as quite the Early Adopter), forked out for an sx56, sx66, 8135, x7510((quad band data)
Just feel a leetle wee bit of a sense, dare I say it, of Entitlement for the TP2 to be enabled into a fully world wide phone.
So we keep hunting, and digging, and dreaming, and .... posting.....
well here is my two cents i have the original unlocked euro version of the tp2 and all i get in the us it edge. it is really impossible to get 3g in the US (2100) because this version of the phone literally does not have the attena for it. and so that you can see all the different types of tp2s and the technical and physical differences between them here is a link: http://pdadb.net/index.php?m=pdacom...&id3=1792&id4=1829&id5=1766&id6=1989&id7=1751

3g in the USA must be on the 1700 band then, as thats the only gsm band that the euro version doesn't support.
Euro version
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100

Anyone know of a good site to order a prepaid SIM card? I plan on using my VZW TP2 in Spain and France. I was also wondering if I should or could disable data and use my TP2 with Garmin XT so I don't get nailed for data usage. Your thoughts would be appreciated...

Exactly what cellular radios does this phone [Telus TP2] have?
My carrier [Telus] has recently completed their 3G overlay, and I'm still showing "EV".
Should I be talking to them about fixing this, or...?
It was (is?) my understanding that this phone was fully 3G capable.
Can someone help me with this?
As far as I can tell, my phone should support the Telus overlay of HSPA on their CDMA network, however I'm showing "EV" an my network type on the notification bar.
I visited a Telus store, and talked to a rep, who just babbled to me about how my SIM was "registered" as a CDMA phone, and therefore I couldn't use HSPA.
>_>
Thoughts?
EDIT: The rep also fed me this convoluted bullsh*t about how when I'm roaming, I'll be able to be on HSPA networks, so I'll get better bandwidth roaming than on my home network...
Wow no one knows the answer to this?
I've searched, and there's no answer, per se, just descriptions of Telus' technology and the antennae in the TP2, which seems to indicate that the TP2 should be able to get on the Telus HSPA network...
I have a SIM-unlocked Telus Touch Pro2 I bought off Craigslist, figuring it'd be good to go when the HSPA network rolled out (Only four months later!). As I understand it, the telus model can make and receive calls on quad-band GSM frequencies, but only use EDGE speeds for data. Has to do with the firmware for the chipset inside the phone. The only HSPA 3G band the phone can use is 2100 Mhz, which is the bad used in Europe, not Canada. It's a major piss-off, especially when a month ago the stores made this out to be the top-of-the-line phone, perfect for ever and ever.
It would seem that should Telus decide to plug in some firmware upgrades, they could activate the new 3G bands, but why bother? We've already signed away our souls to the company.
Who knows, maybe they'll fix it when they release Windows 6.5 for our rig. Because that's on the top of the to-do list, right?
Well there are new radios that we could flash...would that change anything?
Now I may be misinformed but I think that the Telus version is a CMDA phone with GSM capabilites on some frequencies. I do not think it will work on HSPA in Canada as they use different frequencies (850 and 1900). This is why so many people were waiting for the ATT version to come out as it uses those frequencies.
Remember GSM does not equal 3G.
What I would like to know is whether the distinction between 3G and GSM is on the hardware side, firmware side, or software side. Telus would have you assume it's all the hardware's fault, but I'm not sure on that one.
From everything I have read its the chip in the phone that isnt programmed/capable of doing the frequencies required. It may actually be a second chip but I cant confirm that. Other posts have stated that there wont be a software fix to "unlock the frequencies" needed.
GSM is a cellular line and 3G is a data connection.
I just purchased an At&t Tilt 2 unlocked for use on Telus 3G+ network. The Telus Touch Pro 2 is a CDMA , Quadband GSRM and UMTS/HSDPA 2100. The Telus TP2 will only work with EVDO data on the Telus network. If you unlock it for use with Rogers it will work on GSRM with Edge data. That is why I have ordered the At&t Tilt 2. Unfortunately Telus won't honour my unlimited data plan and say it is only for EVDO and that I have to change to one of their current plans to have HSDPA. Like all of the networks, they get your money one way or the other. I'm pleased that with the Tilt 2 I am free to switch providers here in Canada and still get 3G as well as when I travel in Europe.
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
3G Network HSDPA 900 / 2100
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 know this, I don't really care either if you'll excuse my bluntness. The question was simple enough and I gave a very simple answer.

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
