HTC DESIRE 8181 V's 8183 NEXT G DESIRE:

i found this on another forum. thought it be good for the confused ones thinking of buying. hope this explains a little better
So your looking to pick up a HTC Desire of eBay reasonably soon.
Is there any difference between Aus (delivered/imported 8181 Desires on eBay) vs NextG 8183 branded HTC Desires sold on eBay ?
because The NextG 8183 ones on eBay are currently fetching approx $100 more than none NextG 8181 Branded ones.
Q:
Is there any difference between Aus delivered/imported Desires (on eBay) vs NextG branded HTC Desires sold on eBay. From what I can tell they should all support the same frequency space, so there shouldnt be any difference.
A:
There are two different models of Desire....
Telstra sells one that supports UMTS 850/2100 The actual Telstra Next G branded ones have got some Telstra "Apps" loaded into the ROM which cannot be easily removed, however they are simply links to Telstra services. They are unlocked.
Models sourced overseas usually support UMTS 900/2100, which won't work on NextG.
Pick wisely.
Q:
The NextG Versions will still operate on Optus/Voda/etc right? The frequency ranges all seems to match up. Some online stores are selling NextG and none NextG versions, just dont want to shoot myself in the foot.
A:
Yes, the Next G version will work on Optus 3G, but only in metro areas. It does not support the 900 MHz frequency used by Optus or Voda in regional areas, meaning outside city, you'll only get 2G.
It does not support the 900 MHz frequency used by Optus or Voda in regional areas
Hmmm ok, thats weird because according to the HTC Site (and this is where im getting confused) with all the "Exclusive to Telstra NextG" Branding, it supports the following
HSPA/WCDMA:
* Australia: 850/2100 MHz
GSM:
* Australia: 850/900/1800/1900 MHz
Q:
Do they cripple the NextG version and rip out the 900mhz ?
A:
Australia: 850/900/1800/1900 MHz
Those are GSM frequencies, not UMTS.
To make it abundantly clear:
Telstra specs:
HSPA/WCDMA:
•Australia: 850/2100 MHz
GSM:
•Australia: 850/900/1800/1900 MHz
Optus specs:
HSPA/WCDMA:
•Australia: 900/2100 MHz
GSM:
•Australia: 850/900/1800/1900 MHz
3G is around the world but Yes the US carrier At&T use it..
To help you, AT&T use the 850MHZ band while the other mobiles providers (ie T-Mobile) all use the 900 etc if you are grey importing a US phone the rule of thumb is if the phone works on AT&T then it will work on Telstra 3G network..
Telstra have two different 3G networks and they are 'branded' differently, yet they are both technically 3G at the end of the day.
1. Telstra 3G = 2100mhz, is only implemented in metropolian areas.
2. Telstra NextG = 850mhz, is implemented Australia wide and superceeds their 2100mhz implementation.
As you can see they are both 3G. The NextG branded product has more bandwith available to it, (not that 2100 doesn't have enough, just the way Telstra's implementation is).
Speed wise, telstra do have the fastest network, but in time, others will catch up. NextG is not some magical creative, even if Telstra subtly make you think that.
The issue with handsets is that they either come in 850/2100 variants (i.e compable on Telstra 850 3G) or 900/2100 variants (compatible with other networks in australia including the Telstra 3g branded service on the 2100 network).
Futher, this is not to be confused with similar GSM frequencies (then you get 2G coverage)
Q:
So is NextG just better coverage, or is it faster too? I was lead to believe there was a speed increase.
A:
Both.
The downside to having more coverage and web speed, is being stuck with Telstra..
If you have voda or Optus, you need the desire A8181.. if you're with Telstra you need the A8183
I have Optus meaning my phone model is A8181 & it's $100+ cheaper
CHEERS:

This is well written explanation, I'm sure it/has helped many ;-)

Rural coverage for HTC Desire with 3 Mobile
I just want to clarify if the same is applicable with 3 Mobile as Voda have meraged. I'm a 3 customer and I'm moving to Trentham, Victoria. 3 and Voda have said there would be call and text coverage only in the area. 3 is bringing out the Desire later this month but I don't know which one. I've been told there's more Telstra towers in the area but will not swap suppliers as I have a good plan from when they were Orange. Thanx for the help.

If you get an 81 and use telstra, it will be slower.
if you get an 83 and use a Non-telstra network, it will be slower.
If you get an 83 on telstra, Root and grab T-Mod.
Simple! XD

Hi there.
I am confused. I am thinking of getting A8183 and am a vodafone user. Will 3g work for me?

I'm pretty sure it says above only in metro areas mate

vodafone going 850mHz

I have the 8183, rooted and running on LiveConnected (Optus). I have very little drama with mobile internet, regardless where I use my phone around Cairns.
I find I get drop outs if I venture too far west, but north to Pt Douglas/Mossman, inland to Atherton Tablelands/Millaa Millaa/Malanda and all the way south to Townsville (including Hinchinbrook region), signal is strong and on song.
I have never understood people that gripe about their 8183s not working properly on other networks...unless they happen to live in Oodnadatta, there should not be an issue.

Desire Frequency in use?

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.

Desire A8181 on Rogers

I picked up the A8181 in Hong Kong and am having some difficulty getting the handset to get any sort of high speed.
I've read through a few threads saying that not having the 3G/H icons is, simply, an icon issue. However, in my case, I can only get E (EDGE).
*#*#INFO#*#* -> Phone Info shows a Network type = EDGE
I have set the APN for Rogers/internet.com.
Any thoughts? Any successful Rogers users here?

Go to you Mobile Network setting and try to choose WCDMA only Network

I'm on Rogers too (well, fido) and i got the A8183 model because I know Rogers does not support 3G on the 900+2100mhz spectrum. I went through this crap with my Xperia X1i, but luckily Rogers activated 3G on the 1900mhz band to take advantage of visitors during the 2010 Winter Olympics (roaming data rates anyone?)
I may be wrong, but i'd say the future looks bleak for your 8181 on Rogers 3G. The A8183 works though, as it's from Telstra in Australia.
Do let us know if you end up getting it to work though!
Cheers

I'm afraid the A8181 wont work on Rogers/Telus/Bell 3G. Those networks use the 850/1900 MHz bands for 3G whereas the A8181 is 900/2100 (Wind Mobile uses those I believe)
For 3G on Rogers you'll have to get the A8183 Telstra model (as mentioned earlier )

Anyone using the A8183 Desire (Telstra) with AT&T in the US?

I've been thinking about getting this unlocked model that is compatible with AT&T 3G. I was wondering if anyone here has done this, and is there a way to get a sort "US-ified" version of the official HTC ROM that can receive OTA updates.
Thanks.

i'm currently using the A8183 in Canada on the Rogers network, which uses the same freq as AT&T for 3g, works great for me. however, if you wait prob a month or so (or maybe even sooner) Telus/Bell will release a NAM of the Desire, they also use the same freq for 3g (Bell, Telus, Fido, Rogers, and AT&T all use 850/1900 for 3g)

i'm using an A8183 (Telstra) HTC Desire on AT&T... in my opinion, you won't get a US-type ROM without rooting and installing one of the custom ROMs... i'm using the DJDroid Froyo w/Sense ROM and have not had any problems. personally, i don't worry about OTA updates because i'll get them on xda first.

I too have an a8183 on at&t. The only problem is that at&t does operate on 1900 mhz for 3g, but 850 mhz will not completely fallout till the end of the 2010. So If you live in nc, ga, sc, or va . The southeast market. You won't have the 3g because they currently run 1900 mhz 3g. I can still stream music on edge pulling 100 kbs up and down.
Patience is a virtue and locally in NC I have seen an internal ATT map showing many cell site upgrades complete, but they have not switched it on yet for 850mhz.
Latest news is for Atlanta and Manhattan switched on.

Thanks guys. I think what I'm going to do is wait and see if AT&T comes out with their own version of the Desire this month, like has been rumored.

At&t will not get the desire. I am an employee and waited and waited. We may get the rumored dual core Qualcomm since it was just delivered to HTC and the incredible went to Verizon. So we are next for the bigger one.
There is a Samsung coming out Sunday, but I just love the support for HTC with xda. You will have 850mhz umts by the end of the year if you live in a 3g area.
What state are you in?

I think I may still wait to see what AT&T comes out with from HTC, even if it isn't the Desire. The new Samsung Galaxy S phone on AT&T looks nice, except for the fact that it doesn't have a camera flash. That's a big omission in my opinion.
I'm in Connecticut, where we already have 850 mhz.

Go for it , because gingerbread 3.0 will be a whole new class of devices. Maybe even dedicated graphics cards. But thats about a year away.
Plus the imei is not registered with ATT so you can get away with a 15 dollar data plan. Dude you got 850mhz. Shazam......
Sent from my HTC Desire using XDA App

it's probably a good idea to wait. i got an a8183 a couple months ago, i love it but the only reason i got it was because my trusty tilt running eclair was run over and for some reason i didn't want to get a nexus (which is probably what i should have gotten). i was banking on the tilt lasting about another year so i could get on the dual core wagon but no dice. don't get me wrong, i love my desire but with all the cool guy stuff just over the horizon i wish at&t would have released the aria a couple months earlier, so i could have bought a less expensive phone to hold me over til the new stuff came out.

I see that Telus just announced they're getting the Desire soon, which will probably run on 850mhz and 1900mhz. So, I'll see what AT&T does and if nothing and the Telus version comes out, I'll get that one.

I live in North Carolina. How can you tell if they are using the 1900 or 850 band for 3g? I found someone selling the HTC Desire for $500/shipped and was going to get it until I saw this thread. Didn't know if there is a way to find out where AT&T had gone to 850 for 3G bands.

RTP area here and we are definitely on 1900 mhz, and will be strictly 850 mhz by the end of the year. Edge is pulling about 100 kbs up and down.

Depends what HTC Desire you have. Some can only get certain types of 3G with certain Desires.

Well, there is 2 models of Desire as far as I know; the A8181 (Not AT&T 3G compatible) and the A8183 (Telstra version, compatible with AT&T 3G). If your Desire isn't working with AT&T, then chances are it's an A8181.

Remove your battery and on the phone lists the model number next to the imei. A8183 is what you need outside of the southeast market until 2011.

There appear to be 3 models of the 'classic' Desire:
A8181 - Euro version with 900mhz/2100mhz UMTS/WCDMA
A8182 - North American version with SLCD screen and 850mhz/1900mhz UMTS/WCDMA
A8183 - North American / Australian version with AMOLED screen and 850mhz/1900mhz UMTS/WCDMA
Hope that helps!

I'm using a htc desire A8183 in Colombia, and it works beautifully with excellent 3G network speed of navigation and a month ago I got the ota update for Android 2.2 Froy. I'm really happy with the phone

[Q] 3G not working on AT&T US on DHD bought in Singapore

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.
