So I purchased a UK unlocked Touch Pro and had it shipped to the US. While I hope there will be an ATT radio rom flash in the future, I have a quick question for the veterans out there:
On the Touch Pro, under the Phone Band settings, you can select "GSM(1900+850)+UMTS(1900+850)"
When I do this all I receive is Edge on ATT, but aren't the UMTS bands correct already for ATT under this setting?

There are several threads on this topic already...Here's one:

Thanks, I appreciate the reply, but I had read through that thread. I understand that the device is likely in need of a reprogrammed ROM to activate the hardware because at the end of the day it is not working. My question is specifically if the phone setting is allowing me to select the two ATT UMTS bands already why wouldn't I get 3G speed?

I have the UK version of the phone as well and I have the same issue. I have selected the right bands for both UMTS and GSM but all I get is EDGE. The reason for this is either a hardware limitation (no radio antenna to support 850/1900 UMTS bands (let's hope not) or the factory installed radio firmware does not include those bands or all those da#@ iPhone 3G users are hogging all the UMTS bandwidth . Hopefully all we need is to flash a new radio or ROM to unlock these bands. Just because you can select this band in phone settings does not mean the radio or hardware support it.
I guess I am crossing my fingers along with you . Thanks!

Even though this is for T-Mobile im sure if tmo gets unlocked att will to. Watch that and post there if someone cracks it they will post on that thread.
I have a question for the guys only getting EDGE when they have the correct bands set.......do you have a 3G enabled SIM card? (aka a USIM, some networks require you use one for the 3G to be utilised correctly).
Hi, in answer to your question, yes I have a 3G compatible SIM. I literally plucked it out of my TyTN 2/ TILT and put it in to the Touch Pro. The Touch Pro automatically found the ATT network, and when I went in to check bands I realized that there was an option for the US UMTS bands. I am guessing that others have been right when they have stated that just because there is a menu option it doesn't mean the radios are properly enabled.

So currently you are using a HTC branded Raphael? Could you post your ROM/Radio details? (device info in settings/system) Also your ROM build (settings/system->about)?

I have a 3G enabled SIM, been using it with the Kaiser for the past year with good 3G reception. I now have the HTC branded Raph (UK version) with no 3G reception, only EDGE. Here's the info on my ROM/Radio:
ROM: 1.90.405.1 WWE (8/1/08)
Build: 19965.1.2.3
Radio: 1.02.25.19
OK so it seems the only radios actually in these Raphaels at the moment are all 1.02.25.19, once we have a decent way to flash a different radio stack to it we can see if it makes any difference both in the bands available and some of the reception issues we are seeing so far.
I'm not an expert in this area at all, far from it, but but was reading Black's post about his AT&T model and he has 1.01.25.16. Is this what you're going to flash it to once the HardSPL is completed given that you know his radio supports AT&T 3G?
I'm trying to keep up...
Has anybody heard an ETA for Hardspl? I know they where testing it. But any rumors on a timeframe?
My new UK Touch Pro (radio ver 1.02.25.19) is exhibiting this same behavior on AT&T... I have tried all combinations of those dropdowns under phone options without any luck. It does seem very strange that HTC put the US 3G bands in the band dropdown, but included radio software that doesn't support it...
... Why would HTC bother removing hardware supported bands in the software?

Because they couldn't get it working well enough in time for the release date, I guess. Similar to what appears to have been the case with the Diamond. The US isn't their main concern at the moment, so delaying a US-compatible version for now in or der to get it to the rest of the world on time.
Either that or it's deliberate act to slow down the grey imports until they do a proper US release in hand with the local carriers.
If AT&T doesn't want to subsidize the Pro/Diamond, HTC doesn't really have to worry about putting in 1900 support. And honestly, AT&T is too busy with the iPhone 3G to care about HTC.
On the other hand, I'm sure HTC is very interested in getting in on T-mo 3G (1700/2100). By downplaying 1900 (which is being eaten up by the iPhone, anyway), HTC can gear up for the fresh 1700/2100 band. Paired with Android, HTC could potentially gain a big chunk of US 3G networks.
I'm a touch pro user in Canada on the Rogers network. I too hope that HTC releases a radio that allows 3g network access. I don't think its a hardware limitation because it wouldn't really make sense to make two versions of the same phone just to disable parts of the radio.
I disagree with the statement that AT&T is too busy with the iPhone 3G to care about the Touch Pro. The fact is that the target audience for the two phones are entirely different and that a considerable amount of AT&T corporate customers still require their employees to use PPC based phones (even if the iPhone 3G supports email push).
Corporate standards don't usually move as quickly as they should, so of course AT&T is interested in extracting more money from customers that purchased a Tilt over the past 8 months and want to upgrade, but are not allowed to use an iPhone.
If HTC removed support because they were unable to get the software functioning properly, I can live with that. EDGE for a few months while HTC readies a new radio software package is fine... EDGE while HTC readies new hardware is not.

If AT&T weren't interesting in pushing the Touch Pro, HTC wouldn't have went to the trouble and expense of making a specific hardware revision (PTT button) for them. That's not something HTC are gonna do just for the hell of it on a quiet Sunday afternoon.
Maybe I didn't read the thread well enough but did you try and flash the AT&T ROM that was posted? Maybe that might work!
Can you remove the Simlock from a CDMA Evo 3d so that it will be able to use any carrier? Telus or rogers etc... I have tried searching the forums and Google (that was a joke all of the results I could find were commercials for paying someone else to do it for you. I want to do it myself. If possible.
I do not believe you can flash your network over to a sim based network like rodgers due to the fact that cdma phones do not have the hardware integrated inside the phone to run gsm networks or sim based. Your best bet is to flash to another network like boost, virgin mobile, page plus or metro pcs. However any type of esn or meid cloning is illegal and is frowned upon when asking for help on xda. Asking for help will get into trouble here so google will have to hold your hand as you search it's massive data bases to find the method of flashing networks.

AFAIK, MSM8660 (which is inside CDMA 3D) can do both CDMA and GSM unlike MSM8260 (which is inside GSM 3D).... But I believe it's not possible to use GSM service on it, since it does not have a sim slot and a OS to support it. If Rogers have CDMA service too, then it should be possible.
Thanks for that little piece of info sir.

Correct, there is no SIM on the CDMA version. I read about someone a while ago that was able to hack the radio and get GSM to show up, but without a SIM card it is useless. If you could solder a SIM reader on and then hack the radio (which are extremely difficult) you may be able to do it, but it would not be worth it.

You will have Sprint + Rogers/Any GSM carrier
Is there any way to get the AT&T variant working on Verizon? Heard users could flash the T-Mobile radio for them but what about Verizon?
No. Not at all possible.

I think the correct answer is, no one knows yet. Modern smartphones are capable to supporting multiple network types, frequencies and technologies. Hardware-wise, the AT&T, T-Mobile, and (probably) the Sprint versions are identical and differ only by provisioning and preloaded software.

Verizon and AT&T while both "4G LTE" using basically the same technology, have different frequency radios in them. They aren't cross platform capable.

It's not possible, period. Sprint and Verizon operate on CDMA networks, whereas AT&T and T-Mobile operate on GSM. As long as the proper frequencies are supported, any GSM phone can run on any GSM network provided they're SIM unlocked.
4GLTE is currently only used by Verizon for data connections, and not for voice/text--that relies on the 3G CDMA antennae. The same goes for Sprint. The AT&T/T-Mobile-/International HTC One does not physically possess an CDMA atennae. Now before you get your hopes up about using a Sprint phone on Verizon, here's another little wrinkle. As you know, every phone has a serial number. That serial number is known as the IMEI on GSM carriers, and ESN on CDMA carriers. Both Verizon and Sprint operate a massive list of ESNs for everyone phone that can operate on their network. If your ESN is not found on that list, then you cannot activate it on that particular network period, paragraph, end of story. Do not pass go, do not collect $200.
Things get a little murkier with CDMA when it comes to flashing the radios over to other CDMA carriers, but you're looking at services like MetroPCS, PagePlus, etc and that's outside my realm of expertise.

The Verizon and AT&T networks use the different frequencies and technologies. However, the HTC One (like the iPhone 5) is able to run on nearly all permutations of modern phone networks. Apple makes only two versions of the iPhone, one for AT&T and one for everyone else. The AT&T version only exists because AT&T strong armed Apple into removing AT&T's LTE block from the main model.
For example, the Sprint version of the One is a world phone, usable on global "GSM" networks, as well as Sprint's "CDMA" networks. I put GSM and CDMA in quotes because modern wireless networks are more complicated than either of those two designations, and high-end phones are now designed to deal with those complexities via soft configuration vs. dedicated hardware.

Sort of, sort of. You're going in the right path, but still not quite there. Hardware is still very important.
GSM phones are considered world phones because most of the networks operated in foreign countries run on GSM, right. CDMA world phones possess both antennae in order to access the networks over seas, but GSM phones don't have CDMA antennaes because... well, they don't need them. Your chances of going to a CDMA-only country is so very small that it's not worth while to make the investment. Let's take the opposite example using the iPhone 5: You can't take an AT&T/T-Mobile/International iPhone 5 and put in a Sprint SIM card. You can even do a iTunes restore using the Sprint IPSW onto that phone(actually don't know if that would work or not, but I digress) and it STILL won't get a signal because it physically lacks the antennae.

Again, I was talking about modern phones (like the HTC One), which are designed to be multi network and multi frequency global phones by default. HTC makes three versions of the phone: UMTS/GSM Only (MDM8215), UMTS/GSM+LTE (MDM9215), CDMA + UMTS/GSM +LTE (MDM9615). Sprint sells the version using the MDM9615 chipset which supports CDMA + UMTS/GSM + LTE. The Sprint variant has the capabilities to support all of the US/Canada frequencies, but I don't know what would be required to activate non Sprint frequencies. Neither do you. It's foolish to make grand pronouncements stating what is or isn't possible with phones until someone has actually attempted something.
Regarding your antenna statement, the HTC One has three antennas, one for WiFi and BT and two for wireless. The phone selects the best antenna to use in any given situation.

I think you're a little confused on exactly what we're talking about here. Yes, you're absolutely right that the Sprint HTC One possess all the necessary ingredients to operate on just about any network/carrier in the world--GSM or CDMA. And, actually, I do know what's required in order to it to happen. For a GSM network, the only requirements to do so is a correctly provisioned SIM cards and the applicable access point names for the network you're trying to utilize. I've personally taken an CDMA world device and used it on a GSM network(VZW iPhone 5 on Straight Talk/AT&T). The Sprint HTC One would even work on Verizon, provided you get the ESN added to the master database of approved devices which is highly unlikely. Source: I worked for Verizon Wireless. Other CDMA carriers like MetroPCS, PagePlus, Cricket, etc do not have this requirement and it's relatively easy to flash Sprint/VZW phones over to their network.
But that's not at all what's being debated. WiFi and Bluetooth likewise have nothing to do with this conversation. As you've correctly noted, the MDM9215M chipset(step 10, highlighted in green) which powers the wireless antennae and allows them to connect to cellular networks does not support CDMA in the AT&T/T-Mobile/International version of the phone. Because of this fact alone, regardless of software configuration, these phones will never operate on a CDMA network. Now if you're an enterprising individual and decide to open your phone, remove the chip, and replace it with one that does support CDMA... you'd still run into the issue of the master database.

The ESN information for LTE enabled smartphones is included on the SIM/UICC/R-UIM rather than the phone itself, so the issue is one of provisioning a given phone's capabilities to work on the VZW vs the Sprint network. I don't know if this is user configurable or if carriers would be willing to do.
Regarding the antennas, the same antenna configuration is used on all models. There is no additional antenna on the CDMA capable model. That functionality is provided by the Qualcomm MDM9615. It's a bit unfortunate that HTC didn't take Apple's approach in using the MDM9615 on all HTC One variants. I assume that VZW's decision to pass on the phone may have had something to do with it.
Now back to your original point, I was mistaken and you are correct. While the Sprint version could potentially be used on AT&T, T-Mobile and Verizon. The AT&T (UMTS/GSM+LTE) version cannot be used on the Verizon network, and that's a damn shame.

IMEI/ESN is carrier specific. Can't be changed. However can't we trick the phone itself through software to unlock the capability of using a Verizon LTE Sim in a Sprint phone. Flash a Verizon ROM? Sprint and Verizon are the exact same CDMA/LTE band, same internal hardware.
Speaking only of using a Verizon LTE sim for data on a Sprint device. I have a Sprint One. Not with Sprint any longer. Want to use my device as a PDA, internet capable.
Hi there everyone,
I have a unbranded Aussie GT-I9100 that i bought in cambodia and use it alot here. But when i go back to the USA for a visit i plan on doing some travelling around and want to know if flashing a USA modem pack would allow me better to access more of the GSM networks in the US? I know several networks run on either 1700mhz or 1900mhz for 3G/HSPA+ and this phones modem is not setup to allow access to those frequencies for 3G/HSPA+ . Or is that just how the hardware is setup?
Thanks for the help
Shawn
The phone won't be able to use frequencies the hardware doesn't support full stop. No flashing of modems will change that. Choose a carrier over there that you know uses the frequencies the phone hardware uses (or you might be left with using 2G or even have no connectivity). The I9100 was never sold by carriers in the US (there are no specific US stock roms & bundled modems that you know will work), so you might end up having to experiment if you get poor connectivity with the modem you're currently running. Might want to download as many modems as you can get your hands on before you go & take them with you.
But best advice is as above, choose a carrier that uses the same freqs as the phone to avoid teeth gnashing.
Is there a ROM that will make my gsm sgh-1717 from at&t work on Verizon CDMA network?
Sorry there isn't. That would require a hardware change and I don't think parts are available to do so.
Roms don't enable that - modems do that. GSM and CDMA are two different types of networks. Thats why ^^^^ said you need to have different hardware, but you can't change the modem chip on the mainboard.
