I bought my Diamond in HK-Asia where the 3G HSDPA is 2100Mhz. But I would like use it in Brazil where the 3G HSDPA is 850Mhz. Could I load any USA Radio (where 3G is 850Mhz) on my device to convert from 2100Mhz to 850Mhz HSDPA? Will it works?
As i think with the Radio roms as they are Quad band it should work, if its not an CDMA diam
Edit: Okay, sorry just speculation !
no you will not get 3g speed, only edge.
Finally decided to get a T-Mobile US TP2
Q0. Other than the looks, what else is different between the International Unbranded HTC TP2 and the US T-Mobile TP2
Q1. I've been told the US 3G bands are different from the Asian / UK 3G bands. The Asian bands if I'm not mistaken are "HSDPA 900 / 2100". Can anybody cite the US bands? Also I know that 2100 is common for both US and UK... will that be enough to use 3G in Asia?
Q2. Obviously I would need to get the phone SIM unlocked. For once I couldn't find anthing on XDA to unlock the TP2. Any light on that would be great
Q3. I noticed that Hard-SPL is now available for TP2. I'm assuming that means I can flash it with any ROM. Would doing that automatically unlock the phone to be used with any SIM?
Need answers to these real fast guys... got a good deal on eBay.
0. mostly looks and 3g bands
1. tmobile 3g is strictly for tmobile 3g. anywhere else and its edge for you
2. no free sim-unlocker yet
3. Hardspl is for flashing roms...completely separate from sim cards
Oh man... that sux. I was really hoping that atleast one of the T-mobile bands would be compatible with the Asian 3G bands. Do you have any idea what bands T-Mobile operates on?
HSPA/WCDMA
1700/2100 MHz
Note the 2100 band is part of AWS which means it's not compatible with Asia 2100. T-Mobile 3G requires both 1700 and 2100 to operate. One band is upload and one is download.
Quad-band GSM/GPRS/EDGE
Quad-band 850/900/1800/1900 MHz
What exactly is the AWS?

Advanced Wireless Service, which utilizes band IV (1710-1755 out; 2110-2155 in) for CDMA, UMTS, and LTE
Will I be ok travelling with this phone to Europe and Canada and getting 3G? Will the bands work? If not, is there something that can be done to make it work? I'm abot to get one and would like to confirm.
Thanks.

the t-mobile rhodium supports UMTS 1700 and UMTS 2100 so if canada and/europe use those bands for UMTS (3G) then yes it will work. If not, the device is quad band GSM so no problem using voice and EDGE for data.
Also make sure the device is unlocked if you plan to put another carrier's SIMcard in the device.

Not sure about Canada...but TmoUSA 3G bands are different than Euro-3G.
Unrelated, but worth mentioning: the T-Mobile USA international roaming charge for data is steep -- $15/megabyte.
If you got a Euro sim card that would fix the $, but not the radio (for 3G).
The T-Mobile version supports AWS and 2100 3G so works fine in Europe and most other locations. Had 3G T-Mobile and 3G Orange in the UK, but I would suggest a local SIM too. For the UK, both T-Mobile UK prepaid and Virgin UK prepaid work in a locked T-Mobile TP2 or get it unlocked for more choices.

You used a T-Mobile USA version of the TP2 in Europe and had a usable 3G data connection?? Hmmm...that's the first I've read of this.
If this is well-known (and if so, maybe I'm just clueless ) can you provide a link to more discussion, that is...uhh...evidence...of it? Not about what bands the USA version supports -- I know that part -- but other reports/disucssion of it actually working.
On the other hand, are there any reports of a Euro-TP2 that can work on 3G bands in the USA?
USA TMO TP2 will work on TMO 3G in USA. It may also work on WIND Mobile for 3G data here in Canada, not sure about voice as they are using some strange network setup.
As the phone is UMTS 2100 capable, it will get 3G data and voice in most places in Europe and Asia.

Have you tried a TmoUSA TP2 in Europe or Asia -- yourself -- and accessed 3G data?
I'm still doubtful, but I actually hope I'm wrong 'cause I'd love to be able to get 3G data on my TmoUSA TP2 while traveling in Europe...as long as I get a Euro sim card. Otherwise, faster data just means more roaming-$$.

Check the specifications. It supports both 1700 and 2100 UMTS. That means it will work in Europe. ALL Touch Pro 2's have 2100MHz UMTS and quadband GSM, every single one of them, including the CDMA ones. The carrier specific ones add certain bands.
European Touch Pro 2s have UMTS 900
CDMA Touch Pro 2s have CDMA bands
T-Mobile USA has 1700MHz AWS band
AT&T has 850/1900MHz UMTS
TP2 overseas vs versions
I believe, as I've use phones often in the US and overseas, that T-mobile uses 1700 UMTS in the US, but that their TP2 is also 2100 UMTS. Just as At&t Tilt uses 850 & 1900 UMTS (At&t requires both frequencies), but also has 2100 UMTS. As such, both should work in most European, African and Asian countries (verizon and sprint you,re mostly screwed).
I believe the older Tytn II (tilt) was sold world wide as a 850/1900/2100 phone, so you could basically buy it anywhere and use it here on At&t only for 3g or T-mobile Edge only. Unfortunately, the TP2 is sold mostly as a 900/2100 UMTS worldwide outside the US, so you are stuck buying the US versions that correspond to the US networks. The bonus of the At&t tilit 2 version is that it is 850/1900/2100, so it will work almost anywhere. The drawback of the T-mobile TP2 is that 1700 is used by almost no one and while you can use it in most of the aforementioned places, you can't use it in the Americas outside the US & Canada.
Check out this handy wiki UMTS page: en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
Just a note, I almost always pick up a pay as you go sim in other countries- much cheaper and very little hassle. Worth it for anything over a week stay. Maybe not as much so in some of Western Europe.

That is correct. Apparently they are only able to have 3 3G frequencies (though NTT DoCoMo is currently working on a chip that can handle 8 frequencies!)
At first Europe only used 2100MHz 3G and AT&T had set up on 850MHz/1900MHz. Since those were the only 3 bands, HTC would put all three of those bands in its phones up to the Tilt (Kaiser). Once they made the Raphael though, there was 900MHz 3G in Europe and T-Mobile had chosen the AWS band.
Since they can apparently only put 3 bands in, and Europe now needed two for 900MHz/2100MHz, they could no longer put but of AT&T's frequencies in. So they must have just dropped them.
The AT&T version (FUZE) has 850MHz/1900MHz and also has 2100MHz, which is the dominant band for 3G in Europe. I am not sure if they are using 900MHz there yet, but they decided that was more important to put in the European ones than AT&T's bands.
T-Mobile's 3G phones get AWS and 2100MHz. I think AWS might use 2 of the bands because it is split on 1700MHz and 2100MHz (but a different 2100MHz apparently, maybe low 2100MHz vs high, I'm not sure)

It doesn't just support 1700 and 2100, it uses both to work: 1700 for up/send and 2100 for down/receive. So, how does the Tmo USA radio cope without 1700 band for up/send when it's expecting it?

So, the full story (?) is that T-Mobile uses 1700+2100 (up/down) in the USA (which is what I already understood/knew) and in addition to that pair there's a separate slightly-different 2100 band that's used outside the USA? -- That, I didn't know.
If that's the explanation, that makes sense. But confusing that there's 2 different 2100 bands...
I may have to use some frequent-flyer miles and go check it out...

According to Wikipedia, UMTS Band I (commonly known as 2100MHz) uses 1920 - 1980 for uplink and 2110 - 2170 for downlink while UMTS Band IV (AWS, 1700MHz) uses 1710 - 1755 for uplink and 2110 - 2155 for downlink.
Band II (1900MHz) uses 1850 - 1910 for uplink and 1930 - 1990 for downlink and band V (850MHz) uses 824 - 849 for uplink and 869 - 894 for downlink. The uplink and download for these are close, unlike bands I and IV.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
I just assume they are only able to have 3 different frequencies since I have yet to see a UMTS phone with 4 frequencies. But as I wrote this, I'm not too sure because there were phones with Band I, Band II, and Band IV which would mean that there are chips capable for 4 different frequencies? Who knows, maybe someone with actual technical knowledge about this can say.
Also according to that page, there are five different UMTS bands deployed across the world. A bit of a pain. That is more then GSM ever had and who knows if it will grow to even more. LTE also will be coming in before GSM is phased out, so we are going to have to have phones that have GSM, UMTS, AND LTE. GSM will be no problem, quadband has been standard for a while, but having a phone that has both your carriers UMTS and LTE frequencies is going to be tough unless you buy it from your carrier.
What they should have done is just used the band names, and not their frequencies. It would be much easier to know that Europe runs on band I and T-Mobile USA runs on band IV and the T-Mobile Rhodium supports both Band I and Band IV.
Hello, I have a HTC Desire Z A7275 (Bell Edition) phone, unlocked. The specifications are:
Network:
HSPA/WCDMA (850/1900 MHz)
GSM/GPRS/EDGE (850/900/1800/1900 MHz)
Here is my question:
I am planning to travel to UK & Europe next month. 1 Will this phone work on in UK & Europe? 2 Will this phone support 3G or 4G network in UK & Europe? 3 What are my options with phone in UK & Europe? What network will this phone support?
Thanks
My understanding is UK and Europe are on GSM 900/1800 MHz (voice, EDGE) and WCDMA 2100 MHz (3G). So you will have voice and EDGE service, but no 3G. But I have not personally been to Europe with this phone yet, so can't verify personally.

You will be able to use voice and 2G/EDGE data with any of the GSM carriers in Europe (just buy a local SIM and you should be good to go). Unfortunately, little or no 3G or 4G support (pretty sure that almost all countries in Europe support 2100 or 900 with the newer towers---850/1900 is limited to mainly the Americas and some parts of Australia, with a few other small regions here and there).

Every phone has two sets of bands.
GSM/GPRS (EDGE, 2G Bands)
UMTS/HSPA (3G Bands)
As posted earlier in the thread, most European countries use 2100mhz for 3G. So if you want a phone with 3G access, look for the 2100mhz band under the UMTS/HSPA portion of the specifications.
*Edit*: Not sure how reliant you will be on 3G but when I was in Europe last summer, data rates were not cheap. Also, Wifi hotspots were readily available in every major city that we traveled to and most times they were free to access. We purchased a cheap 'dumbphone' for emergency phone calls and used an Ipod Touch and my old Touch Pro to access the web over wifi.

Actually, 2100 MHz is Band 1 when talking about UMTS. 900 MHz is Band 8. So this phone will support 3G data in pretty much all of Europe.

Thanks for the correction. Removed the bad info from my post!
Hi, according to what i've read the radio should be choosen to the country and the carrier you're working with, I live in colombia and my carrier is movistar, but im not getting 3g speeds, i just bought a t-mobile g2, i've seen that carriers in colombia are working on UMTS 850 and UMTS 1900, so can anyone help me on choosing the correct radio to my phone?
THANKS!!!!
The 3G bands on the G2 are 1700/2100 and 2100 MHz, so you are never going to get 3G speeds on it, if your network is using 850 and 1900 MHz. This is set in hardware, and can't be changed by flashing radios. So you are stuck on EDGE. You bought the wrong model of the Vision if you want 3G on your network. The only version with compatibility with 850 and 1900 MHz 3G bands is the Bell Canada version of the Desire Z.
