Hi. I recently got a Desire HD. I am in Caracas, connected to Movistar-Venezuela and can not obtain a 3G connection.
I had an HTC Fuze/Touch Pro before, with the same SIM card and had no problem connecting to 3G, and if I put the SIM card back in the Touch Pro it connects with no problem.
I have:
Android 2.2
Baseband version
12.28b.60.140eU_26.03.02.26_M
Kernel
2.6.32.21-g66cfb7a
Build
1.32.707.5
I have tried everything in the standard Settings. Am I missing something?
... sorry if this problem has been posted and resolved before, but I am having trouble searching for "3G" as it seems to be too short for a search term.
Correct me if I'm wrong
Correct me if I'm wrong anyone, but the Desire HD doesn't support all 3G bands, only a few. So that may be why you are experiencing the problem.

That's correct most DHD models support 3G only 900 / 2100 MHz bands, unless stated otherwise in which case it'd be on the 850 / 1900 MHz range.
Chech with your telco as to which band their 3G runs on.

"unless stated otherwise" would mean that the option for the 850 / 1900 MHz exists?
Is it a radio issue? If that were the case, where could I download that radio? or would somebody know if HTC was planning to release one for all bands?

DHD's can only do one of the pairs and it's a hardware thing, don't think radio can switch between them. It's something to look out for when purchasing a new handset.
Not sure why HTC decided to go with this method, given that iPhones (and other phones) are quadband.

Just factory reset your phone. I've had this problem once and nothign worked until I did a reset of the phone.
Same problem here. You may need a different flavour of the phone.
Thanks everybody for your help.
You have been all very helpful.
Though I have to admit I am a little sad. DHD with no 3G connectivity is like a Ferrari on a dirt road...

Apologies if this is a stupid question;
Can I find out what frequency the Desire is using at any time? ie which 850/900/2100 band?
Just replaced an 850/2100 Desire with a UK-originated 900/2100 and the speedtest results have almost doubled.
Just want to see if it is still using the 2100mhz network or somehow it's using a 900mhz band with better results
Sidenote: in Australia we have 850mhz desires
Does anybody have any solution on finding out which frequency the Desire is using at a given time?
Thank you

The 850Mhz is only for Telstra. If you with any other provider (3, Vodafone, Optus) you should get the EU version! If you use telstra one with let say 3 card in it, you will only get 3G when you have access to 2100Mhz network.
My Desire is telstra one and im with telstra, speed test results are better comparing to HTC Hero on 3. Im getting around 500-1000kbps better results.
Only problem is that Melbourne server is gone from speedtest.net, and now we testing connection to Canbera and Adelaide so results will be diffrent.

I live in Mexico and have a European Desire and want to change to 850 since Telcel (cel provider) is what uses.
Any help on how I can achieve this?
wrong problem explained
What I meant was for the 3G 850 band
You have to buy a new phone! The A8181 Desire does not support that frequency - you need an A8183 Desire.

Dave

Thanks for the answer dave, I was hoping there were some software tweaks.

I know I'm dredging up an old thread, but I searched and have not found a way to display which of the 3G frequency bands is being used at any given moment by my Desire. Does anyone know of an app that does this? I would be surprised if there is not an android app that does this, since it seems there are such apps for other platforms.
It's always been my understanding that it's in the chip. But can someone confirm this for me? I'm using WCDMA 1900MHz atm and the operator sucks. There's another that offers 3G but it's on 850 which my desire doesn't support (only EDGE.) I'm quite frustrated.

It's hardware I'm afraid.
The 900 mhz model is the A8181 and the 850 mhz model is the A8183.
Belated thanks for clarification.

How do you know it's hardware? Is there some place you can check which frequency it's operating on?

check the specs for the different models.
it is DEFINATELY hardware.
think about it - if it was software, why wouldn't HTC just produce one model?
very few carriers run 850mhz 3g, so think of the A8183 as a 'special' build.

Well, actually, if YOU think about it: if they make one model, would they be able to charge an additional premium for it?
Is it possibe to change the frequency that the Desire uses?
I just got an HTC Desire but it apparently doesn't use the same frequency as my other phone did so I'm stuck on insanely slow EDGE.
I know this request may sound a little odd but I'm desperate to change it.
At the moment the frequency is: HSDPA 900 / 2100
And I need to get to: 850 / 2100
I saw that you can apperently flash "Radios", is this what is needed? What exactly would flashing a Radio do?
If anyone could help me here it would be GREATLY appreciated, I mean what's a smartphone without 3G internet?
Edit: I just realized that both Rogers and the HTC Desire share the 2100 frequency, is there any way I could enable the 3G on that frequency?
I'm not 100% certain, but I believe the frequencies are a hardware problem - otherwise you would probably see a lot more mods to enable every frequency possible
If rogers is using that 2100 frequency, your phone should be searching for 3g on that frequency, but there might not be 2100 support in your area, as they use 2 different frequencies to make it cheaper to roll out (so in a different area, phones could access the 850 but not the 2100)
Updating your radio might help a bit:
Radios can make your signal a bit stronger, depending on which one you use (the best radio varies per situation/person) So it could let your phone get a higher speed on your EDGE, or maybe find a nearby 2100 signal
Yes, flashing to a different radio version and its associated RIL (if available) can help to improve issues with things like battery life, Wi-Fi performance, and 3G/HSDPA speeds. Some radio versions may work better than others for you as they are region dependant. Give a few a try and observe how good/bad they each perform.

I've got a 850/2100 HTC Desire. While the 850 doesn't affect me, I'd have preferred if I had the 900/2100 HTC Desire.
BTW, just to re-affirm, frequency the device operates on is hardware-based and cannot be manipulated with software/firmwares.

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 all,
I was hoping someone could help me with a problem I've had with my HTC Desire HD. I've unlocked the phone (but not rooted) having moved from the UK to Canada and wishing to use a Canadian sim card in my phone.
However, I don't get any signal or any network with my Canadian (Virgin) sim card. It accepts the sim card and allows me to use the phone, but I get no signal whatsoever. I've tried taking the battery out and waiting 30 minutes, and have gone off and onto airplane mode to attempt to get it to connect to a network, but nothing.
Is this something that rooting the phone could help with? Is the fact that I'm in a different country anything to do with it? The only network it can even find is called 'EXT' but it won't connect. Anyone able to help?
Some extra info:
Model Number: HTC Desire HD a9191
Android Version: 2.3.5
HTC Sence Version: 3.0
Software Number: 3.13.61.5
Any help would be so greatly appreciated.
I'm going to cover the obvious first, you put the sim cover back on right? Its needed for the antenna

Yeah, the cover is back on.
The other strange thing, is that the phone recognizes a Canadian number in the Phone Identity.
I've tried a different Canadian sim card, and that works. The sim card that is not getting signal works in other phones too.
It's all a bit odd.
Sounds like its the sim card is the issue. I had a similar encounter a while back, my sisters tmo sim wouldn't work but my brothers tmo would. So it could be just needing a new sim or the carrier might have some kind of lock on their Sims. Just because a phone is sim unlocked d doesn't guarantee any sum will work its kind of a trial and error sometimes

Thanks mate. Perhaps I'll take it down to where I got the sim card, see if they're able to help me out or not.
Desire HD from UK will not work at all in Virgin Mobile Canada.
VM Canada as being a virtual operator uses the Bell Mobility Network.
Bell Mobility works in LTE band and 3G but 850 MHz and 3G 1900 MHz.
Desire HD does not have those bands in 3G (only 900 and 2100 MHz).
Desire HD has 850 MHz and 1900 MHz band but only for GSM 2G. But Bell Mobility does not have GSM network. Only 3G and LTE.
Here is the list of the mobile operators in Canada. You can use SIM card from any operator which has GSM 850, 900 or 1900 MHz or 3G 900, or 2100 MHz.
http://maps.mobileworldlive.com/network.php?cid=88&cname=Canada
(but please check if any of those compatible operators have any coverage in your area. From the network you found it seems that Execulink Telecom has the coverage but it will be only 2G).
You may see people using there Desire HD in VM network, but if you take a closer look, this is actually HTC Inspire 4G which is basically Desire HD but for the North American market with LTE and different band radio modules.
Hmm learn something new everyday. Didn't know virgin didn't have an 2g network, that explains the op issue

To be completely honest, Bell Mobility has a 2G network, but it's CDMA (also with Ev-DO) so completely another story, not related to Desire HD or Inspire 4G
