January 22nd North American 850MHz HSPA 3G Blackstone...

Saw this news story, does anyone know if it is credible? The NextG Service is on the 850MHz band which is the same as Rogers/Fido in Canada and Cingular in the US...if all this is true then one of these unlocked would be 3G Compatible in North America...Thoughts?

Well that would suck for me because about 3 hours ago I got an iPhone because I really needed 3g already I do ally of browsing and videos but I like the touch he better....

What is the exact issue with North America and the Touch HD? I thought HSDPA was fully supported in our continent under most major providers. Just curious as I'm looking at purchasing one in the future.

The Touch HD that is out now operates on UMTS 900/2100. Telstra in Australia and the North American providers (except T-Mobile) use UMTS 850.

hopefully it is just some software that HTC did. cuz we do have that option to change it to 850MHz 3G in the phone but just nothing happens to it. If a flash can fix it then it should be ok. EDGE for me is pretty fast anyways in Toronto most of the time.

850 mHz is just one of the 2 bands needed to work on US 3G. you also need 1900 . my understanding is one band is for upload the other for download. don't get me wrong, it would be fantastic if the Aussie version was fully capable on US networks. i'll believe it when i see it. heck, expansys even has a note saying they have to confirm the 850mHz 3G band.

850/1900Mhz....
could someone please explain the upload/download at different frequencies paradigm to me?

This is incorrect. With at&t you do not need both. With just 850mHz you will be more than fine.
Now with T-Mobile you would need both 1700 and 2100 not just 2100 or just 1700 both. Just more reason to hate T-Mobile.

I am ready to take the plunge and drop the $ for an HD. I also will switch my number back to at&t from verizon. I guessi cna say almost ready. I really dont want to spend $800 for no 3G

Does anyone know how hspa in Canada with Rogers/Fido works? i.e. are dual frequencies required or is 850MHz enough to get top speeds? Thanks...

Has anyone brought one into the US and had any success getting a 3G signal ?

Some carriers in the US and Canada use 850mhz such as AT&T and Rogers but they also use 1900mhz. It really depends where you live... Whiich city, state etc
1900mhz is growing in popularity in the states.

Sadly, no 3G for me.

You do not need both 1900 and 850. Its only tmobile that u need both frequenes but they use 1700 and 2100. As long as u have ether 850 or 1900 (depending on what freuency ur area uses) u will have 3g with at&t.

No, the *network* you use may be present on more than one frequency, but its not 850 being uplink and 1700 being the downlink.
When we talk about UMTS the downlink is around 850/1700/2100 but the uplink is always a few MHz below that. (to be pedantic, the UMTS specification specifies the exact downlink/uplink separation)
I can't imagine HTC producing a UMTS 850 phone that won't work on ATT/Rogers and Telstra . Telstra only needs the 850 band so HTC can add in whatever extra the US providers use. It will probably be the same bands supported by the HTC Hermes and other phones common to these providers.

for AT&T, you do NOT need both frequencies (850 and 1900) for 3G. They don't HAVE both frequencies in most areas. It's one or the other.
And yes, T-Mobile US sucks ass...

Well I stand corrected then. This is good news then. Just need somebody in the US to buy a Telstra HD and see if it works. I guess it will be dependent on the area though. If you don't have 850mhz.

Lol i guess it took a senor member to say it for anyone to believe it. I only said it in the first page lol. Lets see what happens when the aus model comes out.

So it is decided then IF the Blackstone is introduced by Telstra and working on their 850MHz 3.5G Network THEN it has the opportunity to work in both the US on Att and Canada's Rogers/Fido...I will wait for this device, purchase it and let the board know if someone else doesn't beat me to it!
P.S. does someone think that this release may be with the Android OS for Telstra? It was the Telstra reps that were commenting at CES 2009 regarding Palm Pre and how the next Android phone that they were testing kicks it...who knows probably coincidence...

3G Networks hardware LOCKING to each carrier by HTC

Among those of you with a deap knowledge of the inner working of HTC phone for 3G networks.
Is HTC doing something to phones for each carrier to lock the phone to a specific carriers 3G network and no other.
I'm asking because I was talking with a freind of mine who was given a HD2 as a part of a promotion for use on AT&T 3G network (850/2100). He uses T-Mobile and tried to get it to work with his T-Mobile SIM with no success. He also told me he had a conversation with someone from HTC that told him that he would no beable to get his HD2 to work on T-Mobile because the hardware will not work with T-Mobiles 3G network (1700/2100).
If this is the case does anyone know if it changable, is it a Firmware issue that can be changed or is it like hard wired physically?
Then the question is if we are buying these phone, some through contracts others outright, do we want to told whos service we have to use!!
Lets have some good discussion...

there are billions of threads on this.
3g is radio/hardware dependent. he'll unfortunately be stuck on EDGE.

He will have no issues using the phone with T-mobile usa. He will not get 3G because of the bands. He will just have edge. But calls, mms, text, email, and internet will all function properly.

Clarify this please
I bought my HTC HD2 in USA (unlocked) and here in Peru, where I live, I cannot get it to work with 3G. If I lived in USA, is there a way to know with what carrier I would get 3G ?

So you are on Claro in Peru?
For 3G you need a phone with 3G 1900 support. If it is the T-Mobile version, that would have 3G on 1700/2100 bands which would be no good. If you got an AT&T handset (850/1900) it would work for 3G for you.
You need to understand what 3G support your version of the phone has. For example mine (Telstra Australia) is 850/2100 - which would not be able to pick up 3G in your network - however it works excellent with Telstra (850) in Australia and currently working well with StarHub (2100) in Singapore.
Your phone is quad band - but that is GSM quadband not 3G - it is 3G dual band and that is what is important for your connection.

Hi tallmantim ....
Thanks for your response. Yeah, today I did my homework and found that my HD2 has UMTS (HSDPA) 900 - 2100 bands, a fact that is not good because Claro and Movistar in Peru operated the 850 - 1900 bands for 3G.
Question: is there a HD2 version with 850 - 1900 band ????

No, but the Telstra HD2 will pick up the 850MHz signals where they exist. There is no HD2 with the 1900MHz UMTS band at the moment

T-mobile's US HD2 works on 2100 MHz 3G in Europe?

Hi,
The official specs of T-mobile's HD2 says that the supported 3G bands are: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Does it mean it will work on European 2100 MHz 3G too? Nexus one does so I suspect HD2 could too but as far as I could digg nobody had a straight answer to this question yet.
-AlefSin

actually i asked HTC CS before, and the answer is NO!
european countries WCDMA frequencies are the same with ASIAN countries. So no chance for European countries either.

hmmm I don't know JohnQ. In your attached email HTC is saying China's frequencies are different from the rest of the world so how do you say it's the same as Europe? I don't know much about 3G network in China though.

Just a few weeks back it was annoounced that the US operators had all signed up to migrating to the rest of the wold's GSM standards!
So in time we will all be singing from the same hymn sheet!

Accoridng to Wikipedia, while 3G in China is using the same frequencies as Europe in UMTS-I band, the air interface is different (TD-SCDMA vs TD-CDMA).
(sorry, cannot link to the docs since as junior member cannot embed links yet).

Wow, that's... odd! It seems US operators cannot even agree whinin US and now they all want to use the rest of world's standards! That's so un-american!

At&T, rogers, etc are all using european 3G frequencies, which is why you can use device from europe on their networks.
T-mobile US uses 1700 & 2100 (one for up stream, one for downstream) which is why it won't work on at&t etc or european frequencies.
The t-mobile 3G phones use both 1700 and 2100 at the same time; and they cant use 2100 seperately on other networks.

erm att uses 850/1900,and very few operators use the same,none in Europe use these bands

Well, it seems the answer is negative. I asked HTC:
Hi, I'm very excited about HTC HD2 on T-Mobile USA. However there is a cruicial question taht I could not find an answer for yet: Should I get this phone, when I travel to Europe, can I use 3G? The specs say this phone will support AWS/2100 MHz UMTS. Since the 2100 MHz is the dominant frequency for western european 3G networks, does it mean this phone would work on their 3G networks? Nobody at T-mobile's support could answer me so I hope you could solve this mystery.

And they answered:
Thank you for contacting HTC Technical Assistance Center. I understand the importance in researching a phone before you purchase it. This is a unusual situation and one T-mobile may not have been experienced with. For T-mobiles network the phone will be using the 1700 and 2100 bands. Although the 2100 band is common world wide. allowing the phone to pick up the edge network. T-mobile uses the 1700 for there 3G services. This band as far as we are aware is only used by T-mobile when it comes to major carriers world wide. More then likely the phone would not be able to pick up 3g if taken over seas.
However. T-mobile dose have a few branches in Europe. You may wish to check with them to see what bands they use for 3G, and if they have had any conflicts with American phones.

OK things are starting to get weird. I received a negative answer from HTC's customer support but then I found USA T-mobile G1 users that reported their phones were working on 2100 MHz 3G in Europe (G1 like US T-mobile version of HD2 only supports 1700/2100 MHz 3G). I need to buy a phone and these contradictory reports leave me confused

Here is what T-mobile says in the specs sheet of the new HD2:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

I tested my unlocked TMOUS HD2 in Sweden using 3's network and worked like a charm in 3G

Bit of a bump here as I'm trying to use my unlocked US T-Mobile HD2 with Orange in France and I can't do better than Edge (it went down to GPRS at one point...). I guess it could come down to spotty reception but I do get 3G speeds in my current location with an iPhone 3GS so I'm not so sure...
I'm using the AmericanAndroid ROM, maybe that's why my speed is throttled ;-)

I am using HD2 T-mobile in Serbia and i have no problem with conection or data speed.
I was on vacation and i didnt use Wifi ,and i used the phone all the time on 3G - the 3G network is incredibly fast, I even think that it is twice as fast as the EU HD2, which I used before..

Thanks, will check again then, maybe bad reception then!

[Help]Rogers Magic not working in Japan/Korea

I have an unlocked Rogers Magic that I have been using for more than a year now. Everything was fine until I started travelling on work to Japan and Korea.
In those 2 countries I had never gotten a signal no matter what setting I tried to put it on. Even going into the band selection using *#*#4636#*#* it didnt work.
I saw something on the web about the Rogers Magic not having the same supported frequencies as what is used in Japan.
What bands does the Rogers Magic support? close
HSPA/WCDMA: 850/1900 MHz-Up to 7.2 Mbps down-link and 2 Mbps up-link speeds

Nope. It has to have the same frenquency to get on those network. This model is designed for European and North American bands. Any country (in the 228) using GSM (tri or quad band) should work.
EDIT:
Docomo (North America use UMTS1800(Band II) technology.)
Docomo provides 2G (mova) PDC cellular services in 800 MHz and 1.5 GHz bands (total 34 MHz bandwidth), and 3G FOMA W-CDMA services in the 2 GHz (UMTS2100) and 800 MHz(UMTS800(Band VI)) and 1800 MHz(UMTS1800(Band IX)) bands.

No they have the 1800Mhz band but they use a different version. Rogers Magic is on UMTS1800 Band II (2). Docomo is using UMTS1800 Band IX (9). Since it is not the same technology (and probably not the same chip) it won't connect.
Docomo is prototyping a 8 band amplifier so it can range from the 700Mhz to 2.5Ghz but there is nothing mainstream for now. If it works and can be manufactured they could offer this in the future. For now you should look a basic phone working on their network.

[Ask] How to enabling 3G/hsdpa capped?

I bought this HTC Aria from USA and use it at my country (Indonesia) But unfortunately the signal is capped to search only gprs or edge, cannot hooked to 3G or hsdpa network..
I also have the asian market Aria, that works perfect in "wcdma only" netwotk. It don't have at&t logo on the upper right screen.
Question is how to make this at&t Aria working on my country wcdma network, bcoz I think that hardware already supported.. I just don't know how to hack it
I believe that its all about software or radio file or something like that , so I put my question here in this sub thread.. So sorry if I do a wrong post.
Sent from my Liberty using Tapatalk

I think it is more a frequency issue than a lock issue. This is a world phone and no frequencies are locked. But if your carrier doesn't use the same 3G frequencies, it will not work on 3G. The 3G frequencies for the Aria are 850mhz and 1900mhz. Your carrier is probably using 900mhz and 2100mhz for 3G. Your only fix (if this is your issue) is to either buy another phone or change carriers.

Not to threadjack, but do any US carriers use the [apparenlty] more common 900/2100mhz for 3G?

Nope. Neither AT&T or T-Mobile use 900/2100 for their 3G frequencies. AT&T uses 850/1900 and T-Mobile uses 1700(AWS).

The Aria should work
HSPA/UMTS/EDGE/GPRS/GSM; Dual Mode UMTS/HSDPA/HSUPA (1900/850MHZ) & GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ); HSDPA/UMTS (3GPP Release 5 Compliant; 7.2 Mbps Enabled) EGPRS Functionality

It's supposed to be a quad band.

No the HTC aria is not quadband for 3g or hsdpa. Basically there is a US versiont the 850/1900 . In Taiwan they released another version with the 900/2100. So if where you live doesn't have a place that uses the 850/1900 your basically stuck w/ 2g speeds.
