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.
Dave
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.

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....
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.
Infuse 4G never sold in Malaysia and Thailand officially...
Works well in Malaysia but 3G is not working in Thailand.
Anybody knows the solution ?
Should flash specific Modem ???
Thanks, guys...
1. What 3G bands are present there on the network you are on?
2. Are any of those bands present in Infuse?
Even within US, T-Mobile SIM in Infuse won't give 3G 'cos of bands incompatibility.
ic...
Will check and report here again,
Thanks, Dud...
Hello pal,
Infuse only support 3G - HSDPA 850 / 1900 / 2100 but Thailand Providers (AIS, DTAC .. and others, I am not sure..) only support 3G / HSDPA 900 / 1900 / 2100..
So I think no matter what Modem you flash on Infuse, cannot use 3G in Thailand.., I think.
I also found out something weird is,
Almost every Samsung phones support HSDPA 850 /900 / 1900 / 2100 EXCEPT INFUSE 4G.
So this is because of bands incompatibility as diablo009 said...
Thailand Providers Truemove and DTAC support 3G band 850 MHz
( 3G UMTS/WCDMA , 3.75G HSPA(hsdpa)/HSPA+ )
Modem UCKL2 works fine.
Hi guys,
I'm looking to buy a Galaxy SIII from the States to use here in Australia, and am having a hard time understanding the intricacies of the cellular bands. I get that CDMA stuff is a no go (Verizon, Sprint) and that it seems only TMobile and AT&T are possibilities. Here is a chart with the variants and their banding listed. http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
The variants support all 2g frequencies, but I don't understand how the 3g part works. The t-mobile one in the 3g band is
850, AWS (Band IV), 1,900, 2,100 MHz UMTS / HSPA+ / DC-HSPA+
Click to expand...
Click to collapse
, which doesn't include the 900 that some networks use here. Will the phone use only 2G if this is the case? Will that make any difference to me? Will the AT&T one work as well?
Can someone please give me some clarification? :victory:
Below is the info for Aus carriers...
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
Hi,
my name is Andrea and first of all thanks to give me your attention.
I'm in europe, italy, and was watching Z3 model d6683, it's for chinese market i guess, particular version of dual sim model. Now, i've two sim, the operator is "3 italia", and its signal is from 3g to 4g (if the area is covered by 2g signal only, i go in roaming signal, and can't surf etc). Now, i'm looking for a dual sim phone, and both sim have to get at least 3g signal at the same time. I'm not asking to surf with both sim at the same time, and i'm not asking "dual active", not interested if when i call, the other sim goes airplane mode. I'm asking if Sony Xperia Z3 model d6683 has two sim can get both at least in 3g mode during standby and always in general, cause i surf with one sim, i call with the other one, but this last don't want to go roaming all the time. Hope it's clear.
I can get this particular model because an Eshop has it online, but first need to know this problem.
Hope it can, and battery can last in any case.
Or if you know some other phones...
Thanks
None has it?
Help please, if you know this model can do what im looking for, or just another phone..
Thanks
Bro i also have D6683 in which one sim will work as 4G and other as 2G.
Hope i have helped you

So the second one can't get higher than 2g? Are you sure, could be the operator..or is just the phone? And if you put sim 1 to 3g, the second always max 2g?

D6683 is designed specifically for the Chinese market. It uses bands that are incompatible with rest of the world, therefore, it would be mostly useless anywhere else.
The following is from xperiablog.net:

Fdd are here in europe, my operator cover 1800 and 2600 lte. Maybe Tdd too.
But could be enough the fact to support just 3g, but the important would be both sim can get up to that at the same time. I'm just asking this.

The only way to make sure is to test it. When I went to China last month my Z3 Dual worked nicely on Unicom's 2600 band. The first time I've read about D6683, I've got really excited until I've found out that it does not support bands used on North American continent wich makes is useless as a world phone to me. If you plan to use it in Europe only, there is a chance that it will work for you. I was not able to find out what 3G bands D6683 supports because the situation there is quite messy. Chinese 3G network is 80% incompatible for rest of the world, the only network that works with foreign phones is Unicom. It's very similar in Japan as well. Understanding that this phone is targeted for the Chinese market, I am pretty sure that it would be useless in North America (and most likely in Europe as well) on 3G bands. Luckily, with the proliferation of LTE networks while 2G is being slowly phased out, we are going to see more phones supporting simultaneous LTE on both SIMs soon.

Of course stay in Europe lol.
But i do not care the fact could not work here, as the fact I want it to support 3g at least at same time.
I guess user niks answerd the question, but i asked to check a few things via mp. But probaly he's right, the phone could show if, after you set connection on sim 1, could support 3g signal on second one. It's impossibile, i have to admit

Thank you. Maybe we re not understanding each other.
I think it can support 3g and even 4g here. My question is when one sim is on 3g/4g,the other one goes 3g? Not to connect data to surf, just about quality, frequency.. at least..
I'm looking one phone it can do it. Seems does not exist.

I do understand what you mean. It would have to be tested, however, there is a very good chance that it might since D6683 can simultaneously run on LTE bands using both SIMs which no Z3 Dual (D6633) can do. Most of the networks in Canada where I live use 3G for voice (same in Australia) and regular Z3 Dual is useless in such scenario, however, there is a chance it would work fine with D6683 which would become a dual SIM phone to go to except LTE bands.
Hope it can. Maybe will buy one to test it,directly.
Ok, Sony America and Sony China say it can't, as user niks wrote.
A Shop wrote on the sony z3 product crearly it can.
Will write to that Shop and to sony hong kong for the last time.
I don't know where to find my D6683 stock rom HELPPPP...!!!
