accessing 3g

I have an unlocked touch cruise with t-mobile in the us, but don’t understand how, or if I can, use the 3g function for internet data access. My questions are as follows:
1. How do I find out if my phone is the European version or the US version (each has differing specs on accessing the 3g network).
2. If it is the US version, will I be able to access the 3g network on t-mobile or AT&T in the US?
3. If it is the European version, will I be able to access the 3g network.
4. How do I know whether my phone is accessing 3g or not?
5. Is there a software fix to allow me to use either the European version or us version to access 3G.
Thanks in advance for any help you can offer.

there's only one version of the Cruise out:
http://www.htc.com/www/product.aspx?id=798
These are the frequencies:
Network HSDPA/UMTS: 2100 MHz (Europe), 850/1900 MHz (USA)
HSDPA: Up to 384kbps for upload and 3.6Mbps for download
UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band 850, 900, 1800, and 1900 MHz (The device will operate on frequencies available from the cellular network)
It's triband 3G. It is currently working on ATT 3G in the US. I don't know about TMobile is there 3G network up and running, and if so I don't remember what frequency that might be at.
The icons at the top point to what type of network E/G is Edge, while 3G/H is 3G.
You can go into the Phone Settings under Band and see some of the different frequency choices. You can force it to be on Edge/GSM there or Auto (which will pick up 3G if it's available).

As I understand it (for internet data access) the european version (as alluded to in your quote) works at Network frequency: HSDPA/UMTS: 2100 MHz (Europe), the American version at the frequencies: 850/1900 MHz (USA). If my phone is the european version, then it works at 2100, and will not access usa networks, unless there is a fix.
t-mobile is 3G in my area.
How to I access the "phone settings under band". I cannot find this on my phone.
Thanks

What I am saying is the device can function on all 3 frequencies listed on the specifications page. I believe the Tmobile 3G frequencies are 1700/2100. You might want to search on the forum and check it out for sure. If it is 1700 you are out of luck. Here are some threads discussing it.

Go to Start -> Settings -> Band tab. If you don't have it, there is a registry tweak that enables that tab.

hmmm, htc told me there were two versions that the european version does not have the capability to switch to the us frequencies, which the specs list as 850 / 1900, but is only using the 2100 frequency. I'm not sure htc tech support is always accurate.
However when I go to the band tab via comm manager, settings, phone, band, it shows me (found with your assistance) that I can select gsm (1900 + 850) + UMTS(1900+850). I assume I should use this setting rather then auto.
T-mobile claims they use the 1900 and 850 bands. I am still at Edge.
I have not had time to read the threads you listed, and will do that later today. Perhaps I will have more questions then, but for now, did I select the correct gsm settings?
Thanks,
Dave

3g access
ok, read the posts you mentioned.
More information about differing versions
from phonescoop.com:
Versions of touch cruise for different regions support different 3G frequency bands.Eurasian version is WCDMA 2100 only)
I assume that since the 850 and 1900 is listed in my setup program, I have the usa version, if phonescoop is correct about two versions.
Since t-mobile works on 1700 I assume I cannot have 3g with them.
Will I get 3g with AT&T?

i personally have never heard of 2 different versions of the Cruise. I have one presumably imported from the UK and works on 3G here.

Btw the Cruise manual says this:
FunctionalityHSDPA/UMTS: 2100MHz for Europe, 850/1900MHz for USA HSDPA: Up to 384kbps for upload and 3.6Mbps for download UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band (850, 900, 1800, and 1900)
There is only one version of the Cruise.
Also a caveat about the bands available in the Band tab of the Phone Settings. I believe some options might be available in the drop down even though the phone doesn't support it. Best thing is to look at the phone specs.

Mmmm... My Polaris shows this:

Bodison,
My phone has the same features in your picture.
1. Hambola states
"Also a caveat about the bands available in the Band tab of the Phone Settings. I believe some options might be available in the drop down even though the phone doesn't support it. Best thing is to look at the phone specs."
suggesting what's in the picture may not be in the phone.
2. He also states:
a.
"FunctionalityHSDPA/UMTS: 2100MHz for Europe, 850/1900MHz for USA HSDPA: Up to 384kbps for upload and 3.6Mbps for download UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band (850, 900, 1800, and 1900)
b.There is only one version of the Cruise."
The phone specs restate what he states in 2a.
A and B seem to contradict one another. Unless it means that the phone is capable of all the MHz frequencies mentioned (850, 1900, and 2100), and when used in Europe it accesses 2100 frequency, and in the US the other frequency. This is not clearly stated in the specs.
If the allusion to functionality does not mean that the frequency used depends on where the phone is used, then therefore there are two versions, with hsdpa/umts for europe (2100) and another for USA (850/1900). In any case, HTC (probably not the ulimate source of reliability) states that there are indeed two versions.
According to Hambola's reference to the caution that what is in the picture may not be in the phone, what is in the picture shows what is in the specs of the phone. He is therefore suggesting that what is in the specs of the phone (as shown in the picture) are not reliable. Not sure what the implications of this are.
I have been reading other posts about 3g with ATT. Is it safe to assume that (if there is one version of the phone, or I have the one that is able to access the US bands as shown in Bodison's picture), that I will be smokin when I switch to ATT in January when my contract runs out?

I am pretty sure there is only one version of the Cruise and it has those 3 bands listed for 3G. In fact there are guys on this forum that have the UK Orbit O2 running on the ATT 3G stateside.

In any case, I tested my phone with a buddy's ATT sim card and was able to access 3G for browsing just fine.
I agree there is one version, though the HTC rep told me otherwise, he was probably....

3G Frequencies

Is there a way to change the 3G Frequencies on the G1 to support AT&T 3G network?

Nope, thats a hardware issue.

I thought it was possibly a software issue. If not, is there a way to change out the chip or the incompatable part to make it compatible?

Nope...not going to work for many reasons.

been answered plenty plenty of times.

From what I can figure a hardware change may not be required with the correct radio but we dont know the right radio without the right hardware. lol I know that makes no sense but it makes as much sense as anyone can make of it thus far. When its possible I assure you I will be among the first to do it. Although Im not ready to try installing a new radio without first acquiring a backup phone but if I do Im gonna give it a try and maybe have better luck than the last guy to try.

What about a mini-usb attachment that can receive atnt signals?
I am sure with that and the right software manipulation it could work.

While it sounds great in theory I doubt anyone would put forth the resources for such a limited market.
You would be best off getting android to work on existing AT&T hardware.

in order to do it we would need hardware which would plug in the bottom and software to tell the phone to use the signal from the attachment.
while there wouldnt be millions in the market i guarantee there are hundreds.
if anyone wants to think about it i dont mind making 50 of em and selling for cost. i have some hook ups in the engineering field i work in

ok, my question is... Europe 3g is diff than tmob usa 3g, but is tmob europe the same 3g setup as US? and if europe 3g is same as tmob europe 3g, is att US 3g same as europe 3g. so if tmob europe is same as europe 3g then a europe g1 should work on att US 3g. am i coming thru clear or am i jumping all over?

The American G1 has 3G support for HSDPA 1700 MHz & 2100 MHz, both bands I believe are used by T-Mobile. In Europe I believe they use only 2100 MHz band for 3G.
AT&T on the other hand uses 850 and 1900 MHz HSDPA
The phone has the capability for 2G at 850 and 1900 MHz, so technically it can be used on their network, just not at 3G speeds.
Although technically it's possible to design a Phase-Locked Loop to operate at a variable frequency and to be tuned with jumpers or something, it's probably cheaper for them or they might be subsidized to make phones so that they are exclusive for one network in the US.
To me the ideal is more about standardizing the protocols and the frequencies used for all companies, and having all bands available for traffic. But at least in the short-term that's not really good for business and so probably won't happen for a while.
This is all based entirely on a limited amount of research and my opinion, take it for what it's worth.

Europe uses 1900/2100 in a pair (1900 is the uplink, 2100 is the downlink). (source)
Most phones produced these days are tri or quad band and can work (almost) anywhere.. I'm surprised the G1 isn't.

*sigh*.
Folks, you need to learn about UMTS bands before complaining about that the G1 or any other phone can't do this or that when it certainly can.
The G1 is a 3g worldphone. It works on the US 1700 AWS network (UMTS Band IV) and works on the world's 2100 network (UMTS Band I). ATT uses the 1900 Band (UMTS Band II).
Apparently the common names for these networks is being confused with the actual operating frequencies because they don't upload and download on the same frequencies. The 1900 band is not the same as the 2100 band, even though the 2100 band (UMTS Band I) uploads in the 1900mhz frequency and downloads at the 2100mhz frequency range. The 1900 Band (UMTS Band II) uploads on the upper half of the 1800mhz and downloads on the 1900mhz frequency range. UMTS Band II uploads on the frequencies that UMTS Band I downloads.
These bands separate.
TMO 3g band is different from ATT 3g band which is also different from EU 3g band.
The 1700 band (UMTS band IV) is actually made up of 2 frequency ranges like the other bands I and II are: 1700mhz and 2100mhz. In fact, the 2100mhz download range for UMTS Band IV is within the same frequencies used for the Band I download range, theoretically making it cheaper/easier for manufacturers who make Band I phones to "support" UMTS Band IV phone production.
Most phones produced today are NOT "tri or quad-band" 3g phones. In fact, I have yet to find a quad-band 3g phone. If quad-band 3g phones were made, they would be very likely to support the T-Mobile 3g network, because it's the 4th largest UMTS band type (behind Band I, II, and V). I would be very shocked to find a phone which was 2100/1900/900/850 instead of 2100/1900/1700/850.
And the G1 is a worldphone. It works just fine on UMTS in Europe. It is a band I and band IV device.
read these 2 links:
http://www.htc.com/www/product/g1/specification.html
http://en.wikipedia.org/wiki/UMTS_frequency_bands#UMTS-FDD
So to clarify, when you see a list of support bands, this is what you should interpret from those advertised bands:
2100 Band = UMTS Band I (The entire world outside of North America)
1900 Band = UMTS Band II (The Americas, ATT)
1700 Band = UMTS Band IV (The Americas, TMO)
900 Band = UMTS Band VIII (Australia)
850 Band = UMTS Band V (The Americas, ATT)
Outside of North America, the 2100 band is almost universally deployed, even where the 850,900,1700 or 1900 band is deployed.

GSM bands and the "g"s

I'm looking to upgrade from my HTC Fuze (AT&T) to the Desire Z, but my main question is, even though it is a quad band phone, will it be able to utilize 3G technology?
With all these changes to frequency bands and technology, I'm at the point where I am not sure what the numbers and letters mean. The specs for the A7272 say it supports GSM: 850/900/1800/1900 and HSDPA 900/2100.
other variants of the Desire Z (A7275) says, GSM: 850/900/1800/1700 and UMTS: Band IV 1700/2100
I'm confused as to whether I will be able to use the phone as a 3G phone for both the US (specifically AT&T) and Thailand.

You can get the Bell (Canada) Desire Z, that includes support for at&t 3G

Sounds interesting. My main worry is using it in Thailand as well, but since I go back to Thailand once a year, I can live with edge i guess.

[Q] HTC Sensation 4G in Germany with UMTS/HSPA *solved*

Hey guys,
I currently own a HTC HD2 in the EU version, without branding.
On my recent holiday in the U.S. I've used the AT & T provider. So unfortunately I had to use only the GSM frequency band as used in the U.S. for UMTS / HSPA other frequencies. UMTS supports my phone with the 900/2100MHz frequencies.
I want to buy me now the HTC Sensation. On the german website of HTC is the following:
HSPA / WCDMA:
Europe / Asia-Pacific RegionT-Mobile U.S.: 900/AWS/2100 MHz
Quad-band GSM / GPRS / EDGE:
850/900/1800/1900 MHz
As in Germany for UMTS / HSPA is the frequency band is used to 2100MHz, which therefore nothing to prevent. Furthermore, although there is "T-Mobile U.S.". Does that mean that I can use with this device in the U.S. with T-Mobile as the provider UMTS / HSPA? Finally, use the AWS frequency band, so a combination of 1700 and 2100 MHz.
That would be great if I could use it in Germany and the U.S. UMTS / HSPA.
Furthermore, there is also the HTC 4G Sensation, but apparently only from T-Mobile U.S.. The internet is not exactly find them if this would also work with UMTS / HSPA in Germany.
GSM Arena writes for the HTC Sensation following:
http://www.gsmarena.com/htc_sensation-3875.php
3G Network: HSDPA 900 / 2100
When HTC Sensation 4G:
http://www.gsmarena.com/htc_sensation_4g-3922.php
3G Network: HSDPA 900/1700/2100
HSDPA 850/1900 - For Bell (Canada)
Here it looks as if the Sensation (without 4G) only work in Germany or the EU. The Sensation 4G whereas in Germany and the USA (with T-Mobile U.S.), because they use the 1700MHz.
In this forum someone writes from Greece, that the HTC 4G Sensation in his work with 3G (UMTS / HSPA). Greece belongs to the EU and uses the 2100MHz frequency band.
http://forum.xda-developers.com/showpost.php?p=14253980&postcount=13
As you can see, it is declared not entirely clear and I would now like to cover before buying, to avoid a bad buy.

Sorry for may incorrect sentence constrcution. For some I used the google translator

Nobody any suggestions?

I am quite interested in this question，too~

There are some news
I asked HTC (Germany), but they could not answer directly. They let my question escalate. This means, that they want to test it. So I had to wait for some weeks ...
Some days ago, I recieved an answer
They wrote the following:
We have heard back from escalation team and was confirmed to us that all the frequencies have been given are supported by the device. So you should be fine.
This was not an complete answer, but the person with who I had written could just say this, what they tell him.
But I´m not sure, if that means, that the:
- HTC Sensation works fine with UMTS in Germany (of course) AND T-Mobile US (in USA)
or that the:
- HTC Sensation 4G works fine in Germany
Does anyone has meanwhile more information?
I examine the tech specs of the HTC Sensation XE and found out, that it does not support T-Mobile US (seen at the network section). I mean, it not written down, but it supports the "AWS" frequency band, which is support by T-Mobile US.
Its soo confusing

Didnt bother about that really, but i am using a Sensation 4G in Germany and it definately has HSPA, the website speed is very fast.
On the other hand it is a US Tmobile Sensation 4G, so i think it will use the 4G in the US as well.

That sounds great !
Are you sure, that it is HSPA? there must be a "H" at the notification bar. To be sure, you can see it in:
settings -> phone info -> network
There must be shown at "mobile network type" "HS(D)PA"
Could you confirm this and which provider do you use in Germany? (and in the USA?)

Yes, i confirm its HS(D)PA, i made two screenshots for you (see attachments).
I am only using it in Germany, my provider is T-Mobile.
Originally it was a Sensation 4G which was sold in the US with a T-Mobile US SIM card.
Sorry for late reply

Hey guys,
sorry for waiting so long, but there are great news
As I found out, there are two versions of the HTC Sensation
- z710e (e for European), named "HTC Sensation"
- z710a (a for America, or Australia?), namend "HTC Sensation 4G"
The European version (z710e) uses for 3G the network frequencies 900/AWS/2100 MHz. This means, that it would work in the USA, but only on 3G with T-Mobile US. With other carriers only on Edge.
The z710a is seemingly splitted into two versions again:
- version 1: supports 3G frequencies 850/1900 MHz
- version 2: supports 3G frequencies 850/1900/2100 MHz
Maybe both versions are the same and are only mistakes by the trader.
Important:
The HTC Sensation 4G (z710a) is available with the frequencies (3G):
- 850/1900/2100 MHz (available e.g. at Bell, NextG, Telstra)
- 1700/1900/2100 MHz T-Mobile US edition (Source: http://www.youtube.com/watch?v=qDDcgweV0B0 at 0:30)
Both are named Sensation 4G (model: z710a), but work on different network frequencies. All carriers Germany uses 2100 MHz for their 3G networks. So all Sensations (with no or with 4G suffix) will work in Germany, because they support 2100 MHz for 3G.
At least a summary:
- there are two versions of the HTC Sensation (z710e and z710a)
- the version z710a is called Sensation 4G (z710e without 4G suffix)
- whyever 4G, because it does not support 4G/LTE ...
- there are two versions of z710a again:
- version 1: supports 3G on 850/1900/2100 MHz (available e.g. at Bell, NextG, Telstra)
- version 2: supports 3G on 1700/1900/2100 MHz (T-Mobile US edition)
- all carriers in Germany uses 2100 MHz for their 3G networks
- so all models will work in Germany on 3G speeds
- not all models will work in USA e.g. at AT&T with 3G speeds
Finally I decided myself to buy a HTC Sensation 4G z710a and it works very fine
It´s from Bell (Canada), but it has no logo or branding. However it has a ROM with preinstalled apps from Bell and has only four system languages. So I cant choose the German language, but so I can improve my English skills
I hope, I could help you with my information

[Q] American HTC Dream support in Europe

Can I bring my T-Mobile HTC dream to England?
It operates on -1700/2100 - 850/900/1800/1900. Will that work with voafone and T-Mobile in the UK?
I'd appreciate a list of supported companies. Also if a company supports 2100 or 1900 but doesn't list 1700 will data work properly?

Wow still using a G1! Right on.
You'll only get EDGE in England (iirc). All carriers in the UK are running 850/1900 UMTS/HSPA (same as AT&T US), and you have frequencies for T-Mobile US, which is different. The reason why the G1 lists as 850/1900 is because that's supported for EDGE, but not UMTS/HSPA.
The 1700/2100 combined for HSPA+ on T-Mobile US is different from the individual 1700 or 2100 used by some carriers in the rest of the world.
So, you'll get slow speeds but you will get some data connection, unless you bring a device with "AT&T" bands.
If you want a phone to run on T-Mo at home and carriers in the UK you'll need one of the few phones (like the Galaxy Nexus) that supports both AT&T and T-Mobile ("pentaband").
