Hi,
In Australia we have two versions of the HTC Touch Pro 2:
T7373 (works on 3g networks 900/2100); and
T7381 (works on 3g networks 850/2100).
Both phones are GSM & 3G phones. Both phones take SIM cards. One is designed for Telstra (an operator that uses 3G 850 Mhz network) and the other is designed for the other carriers (Vodafone, Optus etc.) who use 3G 2100 Mhz network.
I am wanting to flash a T7381 model to get rid of the carrier firmware. I am guessing that I can't flash with the ROM file from "Flashing your First GSM Rhodium Rom (For Noobs) ".
Is there a flash file for the T7381 version?
The reason why I want to flash is because the carrier Telstra has designed their ROM to not allow the Internet settings to be changed to a different carriers settings.
If you are sure what you have is a GSM phone, then you are asking in the wrong forum. Go over to Rhodium GSM forum, download HardSPL from there, and then flash to any ROM you like.
I have the same question.
You have described the problem perfectly, just need a perfect answer. Anyone?
I can answer the question in the thread subject...
CDMA phones come from CDMA carriers, who don't require SIM cards in their phones, so you can call people without the SIM card. These carriers/phones are usually Verizon/Sprint/Telus. These phones use a different kind of technology.
WCDMA is just 3G. I have a T-Mobile USA (GSM) Rhodium. Under Comm Manager, I can set my Network Type (Band) as either "GSM" (2G/EDGE) or "WCDMA" (3G/UMTS).

Hello. I don't understand differences betwen GSM and CDMA so i have few questions.
0. What is the differences betwen this two?
1. In europe GSM is most popular cell network but how is in USA. Is there CDMA network?
2. Can i take my european HTC Kasier to USA and it will be work there with sim card from USA?
Thanks for any help. Best regards.
0) CDMA is newer but expensive compare with GSM but CDMA has better control and quality in data compression when the system reach the maximun number of users in calls. The advantage of GSM is that always is advancing, there're a lot of phone models available, the GSM SIM is a plus, due GSM is old is really well established in the world, with this the roaming is easier..
1) In USA the most popular technology is GSM but there're much more CDMA markets compare to Europe.
2) If the phone is unlocked, yes!
GSM is the way to go, I think. Here in the US, you can't take a domestic CDMA phone out of the country and use it...it's dead in the water. But the GSM phone will work fine, so long as it supports the proper bands.
Now, do I ever travel to Europe and Asia where I need to have to world-phone abilities of the GSM phone? No. But if I did...
Hello,
I am a noob at this so please bear with me.
I have a Telus TP2 and I have unlocked it using the software provided by Olipro.
My objective is to switch my network over to Telus' new UMTS network, using one of their sim cards. Right now it is functioning on Telus' CDMA network.
My question is: Do I need to flash a new Radio to accomplish this? My phone still has the 2.05.00 WV radio on it now. I just need to know if I need to go get a WU radio in order to use Telus' new network.
Thanks in advance.

The Telus TP2 supports UMTS 2100.
Telus uses UMTS 850/1900 for its 3G network.
In order to get the TP2 running on the UMTS network you'll want to grab a ATT GSM variant from the states and unlock that.
IIRC, Telus is jumping straight to WCDMA/UMTS so it won't be supporting the standard GSM bands. If that's the case, then your Telus TP2 variant won't have anything to lock onto when it is in "GSM Mode."
Ah dang, I guess I didn't really need to unlock the sim on my phone then because it won't work on Telus' UMTS network...
Oh well, if I decide to go back to Rogers I believe that the Telus TP2 will operate on their GSM network.
Follow up question:
Do I need to get an unlocked Radio to use the Telus TP2 on Rogers' GSM network or will the 2.05.00WV one that I have on now work?
yes, you'll need a WU unlocked radio in order to access GSM radios in the states, and canada as well, i believe.

It depends on the specific radio firmware in the device.
If it is like the Sprint TP2, then yes, you would need a separate radio. Sprint does not SIM lock its TP2, however it ships them with crippled radio software which has the 850/1900 GSM bands disabled so that it won't work with US GSM carriers (it simply doesn't see the network).
If it is like the Verizon TP2, then no, you would not need a separate radio, though you would need a SIM unlock. Verizon doesn't cripple the radio software in its TP2. It simply uses a traditional SIM lock.
I've heard that the Telus TP2 is like the Sprint model, but I've not seen one to verify.
If you're not sure, then you can always flash the unlocked radio (assuming you're using the unlock software from Oli) and it'll work.
Hey thanks for the information gamescan. I scoured the Telus Mobility website and tried to find information about their new netowork but they just call it HSPA+. No where does it mention that it is UMTS or GSM. Oh well, now I know a little bit more about cell phone tech.
I don't even know if theres any real benefit to being on Telus' UMTS network compared to their CDMA. Im sure there has to be something....

Quick 3G primer:
W-CDMA and UMTS are the name of the tech. It's also referred to as FOMA in Japan. Phones generally standardize on the UMTS name, so when you're poking around in your phone and see UMTS followed by a number, that indicates the frequency band that the phone will run on in 3G.
HSDPA, HSUPA and HSPA+ are all further revisions to UMTS. They allow for greater speeds on existing infrastructure so long as both the handset and tower support it.
A rough CDMA equivalent would be EVDO and EVDO Rev A. Older UMTS handsets will still work on a HSPA+ network, they just won't run on HSPA+ speeds the same as a EVDO handset will work on a Rev A network, just not at Rev A speeds.
UMTS is often referred to as "GSM" though that is a misnomer. GSM and UMTS are two separate (but concurrent) technologies. While they often exist together on networks that have been GSM and upgraded, they do not have to exist together. You can have a situation where a UMTS network exists but an underlying GSM "2G" network does not.
The most well known example of this is in Japan where GSM never rolled out, but in your case, where Telus is adding UMTS to an existing CDMA2000 network, is similar.
From a user perspective, there is no real reason for you to want to run UMTS over EVDO on Telus. Telus should have greater EVDO coverage so that's what you'll be wanting.
If you really want to run on the Telus UMTS network, look for an ATT branded Touch Pro 2 and get that. Of course that will not run on the Telus EVDO network.
Thank you again sir! I appreciate the replies.
Just curious about one thing, if Telus' new UMTS network isn't really any better than their CDMA right now, then why do they promote it as such a big deal?
I think I read that in order to evolve into the next big cellphone phase (forget the name) that this UTMS network was necessary but why would anyone care what network they are on as of today?
Also, do you know why CDMA is not the "way of the future" so to speak? I know Telus spent millions upgrading and putting in new towers all over...maybe I should go google this stuff lol.
The future is LTE (which is neither CDMA or GSM).
As for why Telus made a hop to UMTS before going to LTE, I couldn't tell you.
All I can envision is that Telus is looking to be more compatible globally with Europe and Japanese business travellers. It may also be a strategic decision to open up compatibility with more possible phone manufacturers.
Putting 1XRTT CDMA + EVDO + UMTS into a phone is an engineering pain. Adding in multiple frequency support (and properly tuning the antenna) is also a pain. HTC aside, many manufacturers are supporting GSM/UMTS because that's what carriers have. The biggest CDMA markets are the US, Canda and South Korea. While it is a lot of people, it also requires another phone variant.
By overlaying a UMTS network, Telus can suddenly work with any handset that supports UMTS 850/1900. That's what's used by ATT in the US. UMTS 850 is also popular in Australia while Europe and Japan use UMTS 2100. T-Mobile US uses UMTS 1700. Many UMTS phones offer tri-band UMTS 850/1900/2100 support. With one of those phones you can run on just about any current UMTS network in the world (excepting T-Mobile US).
Again, this is just conjecture on my part, but they are possible reasons.
Hi guys, I bought a Sprint Touch Pro 2 that was being used on the CDMA network, but after moving to Ireland, I realized the phone was automatically unlocked hence any sim works on it.
I have used the Rhodium W Hard-SPL in the CDMA section for it, but am left wondering. Does my TP2 still fall under CDMA or is it now under GSM?
Coz i have tried loading some ROMS under the Touch Pro2, Tilt 2 Windows Mobile ROM Development and it failed and returned an ERROR.
So question is, is it still CDMA and can I upgrade to Android ROM?
Thanks.
1) Yes, the default Sprint radio is unlocked for the Euro GSM bands (900/1800 GSM and 2100 WCDMA) by default. No need to pay for a SIM unlock unless you want to swap radios ROMs.
2) NO, you CANNOT use GSM ROMs. The device can only use the custom "CDMA" ROMs. The CDMA TP2 hardware is a hybrid model, whereas the "GSM" versions are GSM only. The ROMs are incompatible.
DO NOT FLASH A GSM ROM TO YOUR SPRINT TP2 FOR ANY REASON WHATSOEVER.
As far as Android, yes, you can safely load Android via Haret.
Thanks Gamescan for that prompt and to the point reply. Much appreciated.
Just another question if you might know, so which would you say is has better hardware? If the CDMA is Hybrid and the GSM is GSM only, am I to take it that the CDMA is better as it's (for lack of a better word) more advanced, or is the GSM better and why?
Thanks, thinking of trying Android, but, first read alot and see if the advantages outweigh running WM on the TP2.
Same hardware, different radios.
If you're in Europe, it doesn't really matter as every TP2 model supports GSM 900/1800 and WCDMA 2100, which are the Euro GSM and 3G frequencies.
Model choice only matters if you plan on using the phone in the Americas, where the GSM and WCDMA bands differ.
ROM wise it matters because even if you're not using the CDMA radio, the hardware is different and the ROMs are designed to reflect that. For day-to-day use in Ireland though, you'll never know the difference between models.
I just picked up a lightly used Telus TP2
HardSPL, SimUnlock, 2.32.00WU radio, and recent Energy Rom installed
When I put an active sim from a PC mobile (bell reseller) and have phone set to gsm only mode, phone can only see Rogers network
PC mobile (bell) sim package says phone needs to support UMTS/HSPA on 850mhz and 1900mhz
On HTC site the tech specs for the Telus phone show
1X EVDO REV A 800/1900MHz, HSPA 2100MHz, GSM/ GPRS/EDGE 850/900/1800/1900MHz
So did I make a mistake by buying this phone, I do not want to activate with Telus CDMA, I want to use this phone with a Bell SIM.
I'm really hoping there is just some setting somewhere that I didn't know to set.
I own a photon q 4g and did the sim mod
i live in the netherlands where the 4g frequencies are at 800mhz,1800mhz and 2600mhz
when i use the *#*#4636#*#* code i can see the different bands you can select but there is no EU setting
but if i look at screenshots of QPST i can see that the frequencies are usable.
Does anyone think it is possible to get the phone working with dutch 4G?
Is it possible to use QPST on a modded phone with cyanogenmod?
Greetings
Mafradon
What you are looking at is the UMTS and GSM Part, not LTE.
So that's nothing that tell you about usable frequencies.
Besides the LTE part of the Photon Q is using the "flashed" SIM-ID (or whatever name it has).
It can't use the SIM-card from the SIM mod.

but you remove the sim ic in the mod you substitute the sim card for the ic dont you?
Afaik the SIM-IC is/was used for GSM and WCDMA only.
LTE, CDMA etc. is using some in the phone flashed entries.
If you can correct me, please do it. I would love to be wrong.
what rom u are using? and what was your base (cspire / sprint) ?
rom
right now i am using the gsm version of cyanogenmod 10.1 the phone was a sprint phone originally.
I would love to now how the phone ties up the customer to the lte network (aka 4G) as all 4g phones over here do that with a sim card not through the system cdma uses. Or am i wrong altogeter and is an american lte network compleatly different as opossed to a european one?
