Hello Guys,
I am new to this forum and need some help with my DHD which I bought in Singapore.
I am using it in US with AT&T and unfortunately I am not getting 3G eventhough i have 3G service. I am getting EDGE after setting up the APN. Please let me know if there is a way to get this phone working on 3G. I have already called HTC and AT&T and they mentioned that there might be difference in the frequencies.
Thanks
DHD UMTS (3g) is 900/2100 MHz, check what your carrier provides.
My particular carrier in Thailand, TRUE, only broadcasts 850 UMTS, others here use 900/1900/2100.

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:

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

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!
OK...the Desire Z only supports 900 and 2100 MHz which is European and Asian 3G bands. Is there any way that it can be made to operate on any North American 3G bands (like 850, 1700/2100, or 1900) or the issue is entirely hardware related, in which case nothing can be done. I should note that the phone has already been upgraded to 2.3.3 so the rooting options are rather limited.
Any contribution will be highly appreciated!!!
Its hardware limited to the bands you have. My understanding (correct me if I'm wrong) is that with that device (if it is unlocked) you will be able to use a T-mobile SIM to get 3G in the US. I'm not 100% sure with this though, as I don't think the DZ has 1700mhz which is needed for T-mobile.
You don't have the correct bands for AT&T 3G. There is a Canadian version of the DZ that will work on AT&T in the US on 850/1900, however.
The device is completely unlocked and unbranded but its specifications clearly state that its 3G frequencies are 900 and 2100.T-Mobile's 3G is 1700/2100 (together) and it's different from the European 2100. Unless the North American bands can be activated via a secret menu, or by flashing a different radio (impossible with 2.3.4), the phone, as is, can't connect to American 3G networks...only GSM 850 and 1900.
So, a miraculous secret menu appears to be my only hope, which, of course, is impossible to implement if the hardware doesn't support it!
Thanks for your concern!
Well, with you phone, you can use only half of tmo's 3g service since they reserve one band for uploads and the other band for downloads. So technically you kinda get 3g, but just 1 way.

I'm afraid that i can't do that either because the TMO's 2100 3G frequency spectrum is not the same as the European one!
I think I'll exchange it with a friend's European Nexus S which is tri-band 3G and, besides 900 and 2100, it supports TMO's 1700/2100 band! It is an excellent phone but I slightly prefer the metal and the weight of the Desire Z despite the fact that I do not particularly care about the physical keyboard!
Thanks anyway guys!

yea. i think mputtr brought up the correct point. The way T-mo uses 3G is 1700 and 2100 separately for down/up, so like you said its different than the Euro 2100 spectrum.
Sorry it didn't work out.
Hi Guys,
Well, this is my first time posting here, so hello to you all!
Anyway, down to my problem. I have a Desire Z A7272 running on the Australian Telstra network. I just bought a new sim card today that is Next G activated.
I have a few problems which I am hoping to solve by asking you experts First of all note that the Telstra Next G network runs on the 850mHz bandwidth, which I believe my phone does not support. Seeming as I live in regional Australia, this is undesiarable because although 21000mHz is supported and available, Telstra only runs it in the metro area, where it doesn't reach me.
I was searching the net for a couple of days until I found a forum where it explained how to lock the GSM bands. I can't link it as I have lost the page. What I did was dial *#*#4643#*#* and change the network lock to "United States". This was because in the US they don't have the 900mHz band they use the 850mHz band and I was hoping to get my phone to use the 850mHz band.
Now to my 2 problems.
1. When I locked the phone to the 850mHz band, it seems that I can't access *#*#4643#*#* anymore. I type the number in, and nothing opens. I was wondering how to fix this so I could set it up to "Automatic" again.
2. I was wondering if there is anyway hardware or software wise to be able to access and use the 850mHz network. If you could link or quote some reliable/trusted sources that would be excellent. I will take unknown sources but will do with caution, I don't want to break my 2 week old phone.
Thanks guys, sorry for the essay.
Haash.
EDIT: Please note that my phone is running Android 2.3.3 with HTC Sense 2.1.
Your phone is only capable of accessing whatever bands your hardware is designed to. I don't know the specs for your Desire Z, but if the bands you want are not listed in the hardware specs, you will NEVER get them. You would need to investigate whether there is a desire z model built to run on the gsm spectrum you need.
For example, here in the US, Tmobile and AT&T phones can be unlocked to use on each other's EDGE network. But no magic code can ever give them the hardware needed to run each other's 3G network.

Thanks, now all I need to do is get my *#*#4643#*#* working again so I can change it back to the 21000mHz network that I can use.
For anyone wondering:
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
BUT, for the Tmobile G2 (American version)
GSM:
850, 900, 1800, 1900
UMTS:
1700/2100, 2100
Thanks, does anyone know how to unlock *#*#4643#*#*?

It could possibly be that the code you're using isn't correct. I believe it is *#*#4636#*#*

Hi, I was just wondering if the HTC One X (Unlocked) be used with T-Mobile, because I'm currently using a Samsung Galaxy S2 (Hercules) and the lack of ICS is pi**ing me off, I miss my HTC Sensation in which I had ICS months ago; I don't think T-mobile is planning on releasing ICS for the SGS2 somewhere near the future.
For now I'm stuck between Samsung Galaxy Nexus, Galaxy Note and The HTC One X but I don't know if either of the will work on T-Mobile . Can someone please let me know. Sorry for my english.
What country are you in?

Puerto Rico I travel a lot to the states as I work for U.S Deparment of Defense.
This is a very good question. Tmobile claims to use 1700/2100 band for 3g/4g
The specs for the ONE X are : WCDMA/HSPA 850/900/1900//2100 MHz
And GPRS/EDGE/GSM 850/900/1800/1900 MHz
From this information I am unsure whether it will be fully compatible. These numbers look more like an ATT phone than tmobile. Im assuming it will work with edge but 4g is most likely not going to happen. I ordered a one x and intend on using it with t-mobile, so it would definately be beneficial if someone was confident it would work on tmobiles network. Hopefully someone will have one and test it on tmobiles network before I get mine in the mail.

420kushking is correct regarding the spectrums.
However, there are reports that T-Mo iPhone users were able to use 3G on T-Mo network. I've also checked T-Mo spectrums, PCS 1900 mhz 3G spectrums are available on T-Mo on areas in the US. If you're planning to use T-Mo and plan to get the phone, you should probably call T-Mo to see if 1900 mhz is available in the areas you'll be going to most often and make sure that you'll be able to get 3G coverage on your phone. If you ask if the phone will work on T-Mo, the customer service will probably say something like the phone will work on T-Mo but they can't guarantee if the 3G will work on the phone. So it's better to ask of the spectrum is available instead, that might be a safer bet. Even tho the spectrum may be available, but that probably doesn't mean that the 3G will definitely work. These are just some information for you to consider.
I'm also planning to get a One X to use on T-Mo, and hopefully what they say about the 1900 mhz spectrums are true. I couldn't test the 1900 mhz spectrum on my Desire HD because of the 900/2100 bands on the phone.

Well yeah it will work but will it be able to utilize the 4g network I think is the question here. I have already pre-ordered the one X unlocked version and I do have tmobile. I will be doing extensive data speed tests when I get the One X, but I do not expect anything better than an EDGE connection on T-mobiles network.
To me this is a big deal because if the One X does not work with 4g on tmobile, It also wont work with 4g on ATT because its the Tegra 3 version, and if you have been looking at specs the tegra 3 unlocked version does NOT support LTE... If I dont get the speeds I need then it will end up on eBay.

The one x will get 4G speeds on att. "4G" as in HSPA+ not LTE. So you'll get decent speeds, just not LTE speeds. I Wouldn't bet that the one x will work on tmobiles 3G networks let alone their 4G networks. Edge seems about right.
Thanks to you all for answering my question, I was about to pre-order it on when I read that it was "Sim-free", what does that mean, does that mean it has no sim card slot. Im kinda confused here.
Never mind after a bit or reading I've learned that sim-free means it comes with ail, but it does has sim card slot.

SIM-Free means you can use whatever network uses GSM
I don't think the One X will support Tmobile AWS band. The only hope for this phone to work on Tmobile 3G/4G is if Tmobile has switched 3G/4G over to the 1900 band in your area.

Realistically? No, since it doesn't support the AWS Band (1700 AND 2100).
However, if you live in an area when TMo has deployed the 1900 band, it will work. If you live in that area, that is.
Also, "sim-free" means it comes straight from the manufacturer, without a carrier's SIM card.

Nope 1700mhz/2100mhz in here... Sad but true
I was looking for the specs at gsmarena and I found that the at&t versions supports the following bands:
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 850 / 1700 / 1900 / 2100
4G Network
LTE 700 MHz Class 17 / 1700 / 2100
I'm not too familiar with this subject but I believe that T-Mobile uses 1700/2100mhz, does this means the At&t is a true candidate for T-Mobile Compatibility?

I think the version of the phone you would be referring to is the one X att version, It has a dual core qualcomm s4 krait instead of the tegra 3 processor. There is some debate over the performance of the krait vs the tegra 3. I know from a benchmark video that the tegra 3 outperformed the transformer prime. I think the krait outperformed the tegra 3 though by a bit. I ordered the unlocked one x that has the tegra 3 so it doesnt support tmobile 4g or att 4g based off the specs. When I get it I will test on both networks. My concern is that since I ordered the tegra 3 version, it wont be supported by ATT 4g OR t-mobile 4g. We will see I guess.

One X will support AT&T on 3G/4G for HSPA+ but not LTE. AT&T uses 850 and 1900 band for 3G/4G on HSPA+.

Ok good to know. Does anyone have information about speed tests on their regular 4g network? Is the LTE that much faster to where it would be worth it to invest in an LTE based less storage model? I have both att and T-mobile but I think the 4g on t-mobile is faster based off my speed tests. I do NOT have an LTE device to test the differences. I am in Los Angeles/ Orange county area.
I'm considering switching to T-Mobile with an unlocked One X, and appreciate the info in this thread. One question: some are saying it will work with HSPA+ on ATT. Will the phone roam to ATT if it sees an EDGE network in range, or will I be stuck with the lower speed? Oh, and does TMob charge for data roaming to ATT HSPA+?
