Hi, I'm planning to buy one of unlocked Desire on Ebay. there is only one thing bother me. Will desire work under AT&T's 3G network? I know it will definitely work under 2G(EDGE) network, but how about 3G?
I think AT&T uses 850/1900/2100 Mhz band, and the Desire support 1900/2100 Mhz, will that works?
BTW: I'm in Illinois if you are trying to say AT&T is using different band in different states.
thank you very much
My Desire HD works with UMTS frequency 850, which means I can only get GPRS, as my provider uses 2100 for UMTS.
I know there are other variants for the DHD that work with 2100.
My question: Is it possible somehow to hack the radio firmware to make the device work in a different frequency or did HTC actually bother with different radio hardware?
Is there a 850 MHz DHD out yet? The DHD normally has a 900/2100 MHz UMTS radio in it. So it should work. Do you have 3G enabled or is your phone on GSM only?

The radio frequencies are "hard coded" into the cpu chipset, they cannot be changed. full stop. sorry
Hi everyone,
I bought my Desire HD in europe and i have RCMix Custom ROM on it.
This smmer im going to the USA and i was wondering Is my phone going to work on all USA Mobile carriers like Verizon, AT&T and others ?
as long as your phone is unlocked, then why not!
You probably want to double check the DHDs supported frequency bands with that of the US networks.
I'm sure the HTC Inspire is the US version of the DHD that has US carrier support.
From the HTC Spec List:

Network 4
Europe:
HSPA/WCDMA: 900/2100 MHz
GSM: 850/900/1800/1900 MHz
Asia Pacific:
HSPA/WCDMA: 900/2100 MHz
GSM: 850/900/1800/1900 MHz

The next step is for you to check the frequencies used by the US networks (I'm not doing everything for you!!!*) and compare to this list.
I know Verizon still uses 800MHz in some areas (not supported).
*@Andy, I'm nice but I'm not THAT nice!
I was wondering if I purchase an unlocked HTC one, will it work with Verizon?
You have to see the frequencies of the carrier
But, probably, yes!
in a word, no.
It has no CDMA radio, which is required for voice. Not to mention VZW hasn't ever let you bring a device to their network from the outside.

Okay, I checked and the Frequencies are the same but HTC One unlocked says nothing about CDMA. Thanks for the help

VZW uses two different technologies.
the voice is carried on CDMA as is their 3G EVDO data.
LTE is used, but not the same bands as AT&T or T-Mobile.
The only major carriers in the US on GSM are T-Mobile and AT&T (and their mvno's)
Hi, it looks like I'm reviving this thread...
I've done a bit of homework and on htc.com the One specs are as follows:
2G/2.5G - GSM/GPRS/EDGE:
850/900/1800/1900 MHz
3G - UMTS/ HSPA:
Europe/ Middle East/ Africa: 900/1900/2100 MHz with HSPA+ up to 42 Mbps
Asia: 850/900/1900/2100 MHz with HSPA+ up to 42 Mbps
Canada/ Latin America: 850/1900/2100 MHz up to HSPA+ 42 Mbps
T-Mobile (US): 850/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps
AT&T: 850/1900/2100 MHz with HSPA+ up to 21 Mbps
Sprint: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA:
800/1900 MHz for Sprint
4G - LTE:
Europe/ Middle East/ Africa: 800/1800/2600 MHz
Asia: 1800/2600 MHz
T-Mobile (US)/ AT&T/ Canada/ Latin America: 700 MHz and AWS band
Sprint: 1900 MHz
On the Samsung Galaxy S4 for Verizon:
LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(850/900/1900/2100)
It looks to me like the phone supports all ranges and has both styles/types of radios. Has anyone been able to get an unlocked One working with Verizon? Does anyone know how to do it? If I buy an unlocked One, would it come packed with all the network support as listed above or do they manufacture them with only a specific radio/frequency range in mind?

Nope
No
Stop nope, just no.
Verizon and Sprint use CDMA as their base on their Network. The only HTC One with CDMA is the Sprint version. But you can't use the Sprint version on Verizon.
That's why when the Sprint version was released developers had to tweak their roms and recoveries since the outside was the same but the insides no.
Yes LTE is gsm based and requires a GSM radio. And yes when the Verizon HTC one is released it can be used on TMo and AT&T. Since it has both CDMA & GSM radios.
But NO NO NO you CAN NOT use a AT&T, T-Mobile, Dev Edition,Sprint, or Iternational HTC One on Verizon.

which is required for voice.
Until Voice over LTE is fully implemented voice is still falling back into CDMA.

Thanks for your help! I realized I was misunderstanding the way those specs were written, thinking a single phone carried all those ranges and could work equally across the board.
I'm leaning towards getting an unlocked phone for T-Mobile. Any suggestions on where to get it from? If I get it from T-Mobile then it will likely have bloat on it which I don't care for. I could get it from Google Play or HTC's shopamerica...Is there an "easy" way to determine whether or not a phone will fully function on a particular network? Clearly my line of thinking on just making sure the frequency ranges match up is rather off!
Depends what freq your carrier uses for 3G etc. Only the international and dev edition are bloat free. But your at xda there are threads all over the place to help you debloat.
Again T-Mobile is the only one with 1700 3G band.
The dev doesn't have 1700, but has other extra bands. And the international lacks LTE.
Only Verizon will sell their version of the ONE. All the others are all over the internet.

So if I travel internationally and want to have the use of LTE, it sounds like I would need to get the unlocked "international" One? If the so-called "developer" version of the One doesn't have the 1700 band, will one of the other bands take over/compensate? In other words, will the developer phone still be fully functional? I also assume that by "developer" phone you're referring to both the unlocked 32 and 64Gb phones sold at shopamerica.com?
Lastly, here's what I'm doing: I want to buy a phone that I can use in the US and if I travel to Canada, I want to make sure it is compatible with their networks too so all I would need to do is pick up a new sim card and be off to the races. If I'm understanding everything, then the phone on shopamerica should be sufficient.
Any thoughts? Thanks again for the help! I've never dealt with network matching and unlocked phones. Can you tell?!
Stick with the developer edition since it offers more 3G bands ... LTE outside the US it would depend if whatever carrier you use on that country uses any any of the LTE bands it supports.
A lot of the major carriers around the world use similar 3G bands most will work on this phone. Again it all depends on which carried you use.
