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
So basically I got fed-up with seeing so many questions about TP2 models and their supported frequencies.
I'm an American so most of this information is geared towards helping other Americans- but it may also be of use to people in other parts of the world.
If you aren't a big tech-wiz, READ THIS before you buy your Touch Pro 2.
Here is the low down:
There are two different prominent cell phone technology standards in the world today: GSM and CDMA.
Most of the world runs their 3G cellular networks on GSM. However some carriers such as Verizon, Sprint, Bell, and Telus work on CDMA.
GSM= Sim Card
CDMA= No sim card
-Note however that CDMA "world phones" have sim cards because they also include GSM tuners.
Here are the Mobile Telecommunications Standards that matter to you:
GENERATIONS:
1st Generation (1G):
~don't worry about it, only primitive cell phones operated on this standard.
2nd Generation (2G):
~here we go this is GSM!!! This is what matters
~this is also where current CDMA networks really started rolling out.
2.5G:
~EDGE, this is the GSM that you use if you aren't on 3G. EDGE is important, memorize the name!!!
3rd Generation 3G):
~now we are talking, UMTS (Universal Mobile Telecommunications System). In Europe UMTS may also be called "W-CDMA" although it is GSM (sim cards!!!) This is 3G that the Iphone was named after. It is GSM.
~EV-DO (Evolution Data Optimized), this is the 3G of CDMA. this has revisions such as EVDO rev "A" or "B" that can be considered 3.5G
3.5G:
~HSPA (High-Speed Packet Access)= HSDPA/HSUPA. The "D" in HSDPA stands for downlink, the additional "U" in HSUPA stands for uplink.
~ EV-DO revisions.
4G:
~LTE, blazing mobile broadband. This is GSM and what most of the world is migrating to, EVEN CDMA carriers.
~WiMAX. No sim card, because it is not a GSM technology. Think of it like Wi-Fi on steroids. Compare it to LTE like we can compare HSPA to EV-DO today. Understand WiMAX now?
Whew, now that we have all the standards explained, lets talk about what this means.....
DON'T BUY a phone and expect to get 3G on it UNLESS it SPECIFICALLY states that you can get 3G for your carrier on it.
Some common hints:
"European Version"= 3G for many carriers in Europe, EDGE everywhere else, nothing at all for CDMA.
"World Phone"= a CDMA phone that is also capable of GSM. Only capable of 3G (EV-DO) on the carrier that the phone is branded for. Will work on EDGE everywhere else for GSM carriers.
"US Version"= a GSM phone that works on AT&T's 3G network but NOT T-mobiles.
~~Phones that you buy from your carrier will work on your carrier's 3G bands. (Unless your carrier doesn't have 3G yet in your area)
JUST BECAUSE A PHONE SUPPORTS THE SAME BAND DOES NOT MEAN THAT YOU CAN GET 3G ON IT.
MANY 3G BANDS ARE SHARED, BUT ARE SLIGHTLY DIFFERENT. This means that even though carriers such as T-Mobile and AT&T share bands, the phones that support 3G on each are not interchangeable with carriers. EDGE, on the other hand, works interchangeably.
Lastly, 3G support and other wireless standard compatibilities have nothing to do with the software of your phone. You will never find a magic ROM that will enable 3G on a carrier that does not support the phone. It is all HARDWARE DEPENDENT.
Questions?
Also if you need more information, read the posts after this one. There are lots of smart people on xda-developers. I'm sure some will write additional information, clarify, or even correct something that I wrote.
somebody should sticky this, its useful for newcomers

Not necessarily true. EDGE can actually technically be classed as 3G (though it almost always sits in the higher end of the 2.5G tier). 2.5G would more correctly refer to GPRS rather than EDGE, with EDGE being more of an enhancement to GPRS.

When it comes to PDA/WinMo phones "CDMA = No SIM card is false". There are actually a couple of CDMA phones with SIM cards including the Touchpro2.
HSPA is a catch all name for HSDPA and HSUPA, 3.5G techs.
The 3G implementation is UMTS.
If you are talking about worldwide use, EDGE is pretty much not used in the UK... O2 have it on a couple of base stations but its extremely rare, so here you just get:
1G - Analogue phones, Vodafone and O2 had analogue networks but they are now shut down.
2G - GSM with CSD (Circuit Switched Data - make a phone call for data) and HSCSD (High Speed Circuit Switched Data - basically make multiple phone calls and bond them, was only availible on Orange). O2 and Voda use both 900MHz and 1800MHz. Orange and Tmobile have no 900MHz license and use just 1800MHz. 3 Do not operate a 2G network and these days use Orange for coverage where they don't have their own network, they used to use O2...
2.5G - GPRS (General Packet Radio Service) This is the lowest speed you'll get on any network now, up to about 115kbps, on all four 2G networks, indicated by a G on the screen near the signal metre.
2.75G - EDGE (Enhanced Data Rates for GSM Evolution) initially capable of 236kbps, only O2 ever did anything with it, and they did very little with it, for all intents and purposes it is unused in the UK.
3G - UMTS (Universal Mobile Telecommunications Service). This is what is known as 3G in the UK. It uses WCDMA - yes, it is CDMA based, not TDMA as 2G GSM is. Capable of 384kbps, this is needed for video calls (which all UK networks support). Indicated by a 3 onscreen, all UK towns and cities are covered by this or better these days by all networks (advantage of a small country with dense population). All 5 big operators have 3G licenses. At the moment 3G means 2100MHz, Ofcom want to have some of Voda and O2's 900MHz allocation back and allow 3G on it. High frequencies mean short range, making the current band good for getting alot of transmitters (and hence capacity) in cities, but crap for covering rural areas with 3G, you need too many transmitters for cost effectiveness. If Ofcom reallocate some of the 900MHz band and allow 3G on it, it could massively improve 3G reception in rural areas.
3.5G - HSPA (HSDPA and HSUPA). Up to 14.4mbps down (Voda in trial at this speed) other networks 7.2mbps and 3.6mbps. Indicated by a H on screen. Will see this in most major towns and cities.
Say you have an European TP2, which, as we know, does not support AT&T's 3G. Will it support US HSDPA?

Nope, its all or nothing. Even though it supports the downlink band, since it is missing the uplink band it will not support US 3G.
It will give you EDGE however.
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.
I have a Telus Touch Pro2 WWE that I thought I could use on t-mobile's 3G network. I read that Tmobile 3G is from their HSDPA network. Is this correct? I don't know much about this stuff but I thought if I could enable the HSDPA on my phoen I could get 3G as opposed to edge that I am currently getting. I saw there was a fix to enable HSDPA on the tilt. Is there a fix out there to enable it for the Telus WWE?
You should check 3G coverage areas to see if you are covered. I found out this weekend that Im not covered after spending time on the phone with TMo complaining about my data speeds.
The T-Mobile Touch Pro2 supports both 1700MHz and 2100MHz for HSPA, while the Telus Touch Pro2 only supports 2100MHz for HSPA. What's probably happening is that there's no 3G/HSPA coverage in your area at all, or more likely, there's only coverage on the 1700MHz spectrum, which your device doesn't support. You always need to be careful when buying a device not made for your network, as the HSPA frequencies differ between countries and carriers.
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.
