HD2 work on ATT 3G

Does the current HD2 that one can buy from various sources work on the ATT 3G network with a current ATT SIM card?

No, You will not get 3G. the current phones do not have the 850MHZ that ATT uses for 3G.
You have to wait till mid to end of this month when the phone is out with the 850MHZ.

Where is this info from? if this is true I will certainly be getting the hd2. Will it be 850/1900?

The phone will have 850MHZ.
I have been told it will should be out mid to end of this month in Australia.
I bought my HD from there and will be buying the HD2 as soon as it is out.

From HTC australia. It'll come out for the Telstra's NextG network which runs on 850/2100. Since AT&T is overhauling their 1900mhz tower for the much faster 850mhz, the 850/2100 Telstra version is very ideal.

i'm kinda afriad of buying the HTC HD2 that will come to the US in the Q1 of 2010.
I have one question about it ,,, if i bought it " US HD2 " ,, is it going to work outside the US and work with other carrier like the iPhone for example?

Ok let's clear some things up. The "US HD2" is the T-Mobile version. T-MOBILE. What does this mean? If you're with AT&T and bought the "US HD2"/TMobile version, you can talk but will be limited to EDGE for data...no 3G. The HD2 is a quadband phone so you can use it to talk all over the world. Notice that i bold only the word talk? You won't be able to get 3G outside of the US unless the country/carrier you're visiting has 1700/2100 UMTS/3G band (which most don't). So if you're visiting other countries, you can talk all you want, but will more than likely stuck with EDGE for data. Period.
So let's recap:
1) "US HD2" = T-Mobile USA version
2) Telstra NextG HD2 (australian) = compatible with AT&T 3G
3) HD2 is a quadband phone for voice. You can talk on pretty much any country.
4) HD2 is a dualband phone for UMTS/3G/data. You will be stuck with EDGE unless you have the correct band.
5) Tmobile sucks
6) ?????
7) PROFIT!

so if i bought from Telstra NextG, i can work with At&t 3G using at$t? and also TALKING if i'm using other carer like T-Mobile?

Not at the same time. To use a carrier's service (data or voice) you need a sim from that carrier. So to use at&t data you need an at&t sim; to use T-mo voice you need a T-mo sim. The HD2 is not a dual-sim phone, so you can only have one sim installed at a time, and therefore can only be using either at&t or T-mobile at any given time. You can swap sims if the phone is unlocked to use the other carrier's services. I have no idea if the Telstra HD2 will be unlocked or is unlockable...maybe someone who is using a Telstra HD in the USA can respond to that issue.
Hope this helps.

so i take it that T-mo and ATT use different frequencies for their 3g?

Yep,
T-mobile use 1700MHz 3G frequency in the USA when most of 3G compatible devices (at&t) run on 850/1900MHz 3G/HSDPA freqencies

Hi,
I am a new user and I hope I am in the right place.
I just came back from Sydney Australia, and while I was there I bought teh HTC HD2 phone. WHen I got it it had all the Telstra crap on it and It was useless for me since I have t-mobile.
After I bought, I updated the ROM to RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship.exe
I had to use HSPL but I got it to work.
I just arrived to New York today and I could not wait to turn on the phone and see it in action. To my dispointment, I could not get 3G on it. The band and network are set to AUTO. The only thing I get is Edge.
I tried all manual bands and no luck
So then I tried to update the ROM to LEO_2.02.531.14_WWE_B28223\LEO_2.02.531.14_WWE_B28223
But it does not seem to work, no home screen just HTC and the windows start icon, phone and contacts appear on the bottom. Dont know whats wrong?? but perhaps some can shed some light.
Going back to ROM to RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship.exe for now.
Just want to know if I am on the right path?? Will this phone I bought work with t-mobile 3g service?
and what ROM is the best for this HTC HD2 phone and how can I get it?
Any tips would be awesome !
Thanks

That phone will not work with US T-Mobile. Sell it on ebay and wait for the US T-Mo HD2.
T-Mobile uses the weird 1700/2100 UTMS bands in the US, and pretty much only phones made specifically for it will work.

Crap'po'la
I was afraid of that. so I can use it, just wont get 3G
So no ROMS would help right?
Is there A ROM that is better then what I have now? I have RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship.exe
Thanks

hey richsark ill take it off your hands

Hi, well... whats the offer? on a 3 day old phone??

pmed........

pmed............

Hi, The phone I bought straight from the Telstra shop was unlocked. I did put my SIM in it and it registers as TMobile but no 3G. ( I did this in the States) Over there in Sydney with my Tmobile SIM it was 3G !
My guess is the bands are not compatible. I am stuck with Edge I guess... unless there is a way to make it work
Thanks

TMobile will have a roaming agreement with Telstra which means while in Australia you will have connected to the Telstra 3G network using the 850MHz frequency, but as a "visitor". Once back in the US the TMobile network uses 1700MHz which the Telstra version of the HD2 won't work with.
I travel a fair bit to the US and UK for work so prior to the HD2 I had a 850/1900/2100 UMTS phone which covered me for AT&T in the US. Now that AT&T are moving to use 850 more widely the lack of 1900 won't be a problem and 2100 is used widely in the UK and Europe.

HTC HD2 3G Not Detected!!!!!

Hello if someone could help me with my 3G connection inquiry, I would greatly appreciate it.
I bought this phone unlocked from Hong Kong and brought it back to Canada. But the 3G connection through Rogers won't work. I am able to connect to edge (When i pop in my sisters sim card which has a data plan, as my sim card currently does not have a data plan).
I talked to Rogers and they said that everything is compatable (After mentioning the phone frequencies and speed capabilities) and that the only reason 3G isnt working is that I have not configured my phone properly for 3G and at this moment it is configured for 2G (Edge).
I then contacted HTC and they said the reason was because "for the Rogers network, their 3G signal is operated on the 850/1900 MHZ band and the Touch HD2 operates on the 900/2100 MHZ band." Could this be the reason? Will i never taste the pleasures of a 3G connection?
PLEASE HELP!!

since you have bought it in hongkong most probably you have the asian version. It comes with 900/2100 MHZ bands and as you mentioned ROger needs 850/1900 frequency.
You could also get Telstra version from Australia and unlock it as it has 850/1900 frquency so that you could get 3g. But not possible on the one you already have.

Yea its the frequencies. When I take my phones abroad, I always check what frequencies the country has. If the frequencies don't match, the phone won't work in terms of placing calls, 3G etc.

is there a way to unlock ?

There is no software that can get around this "problem"
It is purely a hardware limitation.

perhaps with flashing radio but i'm not shure

x10i on Rogers Network?

Hi,
I bought an x10 from 3 hong kong, fully unlocked. I brought it back to Canada and there's no 3G! I checked all the frequencies and should be all compatible, entered rogers APNs and still no 3G.
Is it possible to get the x10 to work on 3G on rogers?

No unfortunately. The X10 you got from Hong Kong is the international version and it does NOT have the correct 3G bands for Canada/US. You do get quad band GSM but you can only get EDGE. You would need the American version of the X10 in order to get 3G.

Yeah, tough luck. I'm still confused as why AT&T and T-mobile has different 3G bands. Rogers and AT&T use WCDMA 1900 MHz bands while T-mobile and what feels like the rest of the world (just kidding, but at least Europe too) uses WCDMA 2100.
Stop me if I'm way out of my league but my question is WHY?
And isn't it possible to just buy the phone from Rogers directly, cash?

Yea you can buy the phone from Rogers directly with cash but it is still locked. You need to get it unlocked before using it on another carrier.

Why do you need it unlocked if in Canada Rogers is the only one using that frequency?

that's the problem. i can't use rogers phones since i travel a lot. i have to buy a world phone of some sort.
I heard you can root your phone and change the frequencies. is that possible?

I was assuming Flamso might need it for AT&T or some other carrier. Also, it's not just Rogers that uses the frequence. We do have Telus and Bell now. Buy an X10, get it unlocked and use it on Telus or Bell.

Telus and Bell aren't CDMA?
I know Fido and Rogers are the same.

You shouldnt have a tough time selling that one here. Doesnt it support the aws band that wind mobile runs on? AWS 1700 i think

email me if interested

i have the luster white x10i from one of the ebay seller in HK, and it works with T-mobile USA 3G network. UMTS band is 900/1700/2100. Rogers are using 800/850/1900/2100. I dont think you could change the frequency as it is part of the hardware.

Is there a way you can boost edge speed? i can't load facebook or weather with edge. it always times

Cheapest Canadian X10 unlock: http://www.mobileincanada.com/?l=en&u=all&coupon=facebook $5 CAD
T-Mo US and AT&T use different frequencies because spectrum is regulated. Whoever has the deeper pockets can buy more of it.
T-Mobile & Wind Mobile use the same 3G frequency (Band IV 1,700 Mhz) whereas Rogers and AT&T use Band V 850 Mhz.
Telus and Bell Mobility are also now HSPA so you can use unlocked Rogers 3G devices on their network too.
Bell has a tool on their website where you enter in your IMEI and it'll tell you if it's compatible: http://www.bell.ca/support/PrsCSrvWls_GettingStartedGuide.page#4

the Hong Kong X10i version will support T-mobile USA 3G network. the UMTS bandwidth is 1/4/8 which is 900/1700/2100. I got my luster white from hong kong ebay seller, and it works with T-mobile USA 3G network. For X10a (american version) the UMTS bandwidth is 800/850/1900/2100.

so that's why they have x10i and x10a
hardware difference for the 3G network to link with.
x10a is designed for north america
x10i can link on at&t's 3G just because it match

Just sign up with WIND mobile and enjoy because the X10i is compatible with the AWS band (same for T-Mobile down south). But if you are out of their coverage area then there won't be any 3G service (falls back to GSM + EDGE).
The X10a from Rogers will work with Telus and Bell HSPA 3G networks once you have it unlocked.

it does not matter what kind of x10 firmware you have. if your phone is originally a x10a, it has att 3g bands that works with rogers. if you flashed it with x10i firmware, you can still use the 3g because flashing the firmware does not change the bands.
x10i will work with rogers but you only get edge aka 2g.

Unlocking Dell Venue Pro?

Hi!
I'm planning to visit the US and want to pick myself a DVP Unlocked for $499(16GB).
I spoke to a Dell rep who basically told me that when you buy a contract free DVP , it will still be locked to T-mobile.
I'm wondering if T-mobile will provide an unlock for it as I plan to use it in Sweden.
If they don't, has anyone tried the alternative unlock websites that exist on the internet? Are they a scam?

They are probably a scam or just a template for now. Someone will probably call T-Mobile for it when they get it, then post the code for us here

I'm in the same boat as you are and BTW already ordered the phone as I'm pretty sure I'll be able to unlock it.
Not sure if the websites are all scam, there are also posts here of people who actually used them in the past. But let's say that if we can get the unlock code for free from T-mobile it will be best.
From my understanding the unlock code is unique per handset based on the IMEI number, so don't expect anyone posting an unlock code. However, look on the T-mobile web site for their SIM FREE Policy.
When you buy the phone for full price, it makes you actually a "former customer" for T-Mobile as you do not have any contract with them anymore so they should have no problem giving you the unlock code. I also think that legally they need to do it.

Anyone else knows the shipping times for within the US? I have until Jan 11.

is the $499 version unlocked?

The 2 units I used, both were unlocked.
these were the 8 gig 449 ones

Canadian here: I spoke to T-Mobile yesterday. They are currently unable to unlock the phone, even if purchased outright. They suggested contacting Dell.
Called Dell america (dell canada is clueless) and they will not be giving unlock codes for a while at least.
expected release in canada is hopefully before the end of the 'holliday season' according to one of the reps.

I work for T-Mobile USA. They WILL NOT UNLOCK the device unless you have service for longer than 90 days. It is manadtory to have T-Mobile service before asking for an unlock , also you need to have the phone you want unlocked on T-Mobile service for that 90 days

Since you work for T-Mobile, are you aware of the issues with activating this phone through the Dell site? Is T-Mobile acknowledging that the problem is on its end, or is it a problem on Dell's side?

What does it matter if you have the unlock code or not? The phone only has T-mobile radio bands for UMTS.

I think it has 2100 (for Europe/Asia) also.

I don't believe that will work as the 2100 radio is set up for AWS.
American AWS UMTS phone radios are set up to transmit signal in "2100" (2110-2155)Mhz range and receive signal in the "1700" (1710-1755)MHz range.
While EU UMTS "2100" phone radios are set up to receive signal in "2100"(2110-2170)Mhz, and transmit signal in "1900" (1920-1980)MHz range.

Actually since the Venue Pro has UMTS 900 support that should indicate the unit has been configured for at least some Asia and European UMTS support. UMTS 900 is not a American UMTS band.

But according to Lionel's blog post stated that the phone spec
Bands/Mode: UMTS 900/1700/2100/AWS
Would it means that is a dual band UMTS support for AWS and Band I 2100Mhz?
My guessing only...

Will wait til Jan 11th and buy it from either Clove or Expansys.
Although I could have saved a couple of dollars on buying it in the us

A couple of dollars? The 8GB DVP is $450 in the US and £440 in The UK, that's a massive difference. Someone will figure out how to unlock it I'm sure.

You have got it backwards. Both AWS and EU 2100 UMTS use 2100 MHz for download; they just use different frequencies for upload. See the table here: http://en.wikipedia.org/wiki/UMTS_frequency_bands
The more recent posts are correct. The facts are these:
1. When a phone's specs list "UMTS xxxx" (850, 900, 1700, 1900, 2100, etc.) it generally isn't a listing of the exact frequecies, but rather the 3G "bands" that are supported. Thus a European phone that lists "UMTS 900/2100" actually supports 3G downloads in the 1920-1980 MHz range, since that is part of Band I or "UMTS 2100".
2. The WHOLE POINT of AWS in North America is to make it super-easy for manufacturers to support the European and Asian UMTS 2100, by using largely overlapping download frequencies. PhoneScoop has a good article on this: http://www.phonescoop.com/articles/article.php?a=99&p=1493. For this reason, you will rarely or never see an AWS phone that doesn't also support 3G in Europe.
3. Even if surelock and others were correct in their mistaken info that AWS transmits on 2100, that wouldn't make it impossible to support both. Many "3G world phones" for AT&T and Rogers support UMTS 850/1900/2100. 1900 is the PCS band, and it receives on 1930-1990, while Band I (or 2100) transmits on 1920-1980, which overlaps. These phones have radios that can switch between transmitting and receiving on overlapping frequencies. You'll just rarely see these two types of networks operating on the same continent.
In closing:
The Dell Venue Pro supports one North American 3G band (UMTS 1700 or "AWS") and two European/Asian 3G bands (UMTS 900 and UMTS 2100).

Thank you for clarifying. As far as I know all the releases WP7 can be unlocked one way or another so it will only be a matter of time until we can unlock the DVP. A Dell Venue Pro 16GB bought in the US would be over £50 cheaper to get than a 8GB one bought in the UK. If you have means of importing one that's a no brainer.

Unlock S8 from Xfinity Mobile and Used in AT&T GSM network

Say I got a Samsung S8 from Xfinity Mobile(Verizon Network), get unlock code from XM, can I use this phone in Cricket (AT&T GSM network). Samsung support said it is ok, but from some threads it mentioned XM Samsung phone, even after unlock, some band will be locked, may not be used on other carrier. Any one tried before?

I don't see any reason why it wouldn't work just fine. The only thing I can see would be certain carrier features not working. But otherwise should be fine

Verizon and anything related to it uses CDMA technology. Whereas Cricket uses GSM.
GSM phones can be unlocked and switch carriers, whereas CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch CDMA phones with your carrier’s permission.
A list of CDMA and GSM devices can be found here
Mod Edit
However, your phone might be compatible with a GSM network as cricket.
You need to check your phone's version and bands on GSMarena https://www.gsmarena.com/samsung_galaxy_s8-8161.php
And also you need to check Cricket's bands on frequency check https://www.frequencycheck.com/carriers/cricket-wireless-united-states
However, if your phone is already unlocked, you can simply insert a Cricket sim card and try to place a call and use the data to see if it works.

Thanks, understood difference between GSM & CDMA, I read other place saying all the Samsung S8 sold in US are same hardware with different firware, as long as I got unlock code from Xfinity Mobile, then I can flash phone to the new carrier specific firmware(AT&T or Cricket - which is using ATT network), can anyone confirm?

You are correct.

Don't think Xfinity SGS8 will work with GSM.
I believe it will only work with other carriers on CDMA like Sprint.

I can't guarantee it as in the past phones have been difficult to switch between Sprint and Verizon. Verizon's will work on all but Sprint based. And vice versa. But by in all theory yes all the us based models have exact hardware. And should be able to be flashed to each carrier with the csc change thread. The if anything a byop. But the best bet would be to take it once unlocked to which ever carrier and have them Install one of there active Sims and see off it works for sure.
Again shouldn't be any issues other than a few change

what's are CSs that need to be changed?

Depends on sub-model you get. If your phone is the N950U it has the following 2G bands: GSM 850 / 900 / 1800 / 1900 & 3G bands: HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 & CDMA2000 1xEV-DO. So theoretically a Galaxy Note 8 model N950U WILL work on ALL networks provided that your phone is unlocked from the carrier branded N950U. Check this webpage for the N950U specs: gsmarena.com/samsung_galaxy_note8-8505.php#n950u
If you look at the model of the phone on the back cover it will say N950U on it. N950F does not do CDMA (Verizon & Sprint), The N950FD is the same as the N950F but the "D" means dual nano sim capable (one for each girl/guy).
