T-Mobile US TP2 in Asia

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

American T-Mobile Touch Pro 2 and travel

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.

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.

[Q] HTC Desire Z A7275 (Bell Edition)

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.

[Q] Is the Samsung SII T989 support HSDPA 850 ?

Hi,
I was looking fot the specs at gsmarena and it says that is HSDPA 850/1700/2100 capable, but in another sites, they said that is only 1700/2100.
Can someone confirm me that please.
Thanks.

The phone`s box states it is HSDPA 850/1700/1900/2100 capable. I know data works with At&t, so it has either 850 or 1900 HSDPA frequency but i am not sure if it has both or either one.

The Thing is that Im from Claro Dominican Republic, and is only HSDPA 850, I really need to be sure in order to buy the phone.
Thanks.

Well as long as it is on the box, we should rely on that info. You should not have any problems IMO.

it does work it's been proven already by many that has travelled to Europe on 850

actually most of the Europe is on 2100, of course it depends on the carrier but like 60% of the Europe is on 2100.

N7105 Not working 3G on Argentina

Hello i bought my N7105 on China. It works perfectly but my problem is that in Argentina i have only EDGE signal for Internet Not 3g.
I wish to know because i read a lot.. Because i think my celphone was europe version or korean version, never will know.
I think that the problem is that my UMTS is working on different bands ( 850 and 2100) and in Argentina we use ( 850-1900) so i Would like to know if it`s possible to install a N7100 south american modem to fix it, or what..
N7100 Firmware and Modems.
Just Modems N7100
Search for N7105 Modems (Haven`t Found Yet)
Or i can`t use 3G in Argentina.
Thanks anow Hope u can Help Me

I can Add in What bandwidth work our companies here.
Band V (W-CDMA 850)
Band II (W-CDMA 1900)
I think my company is working on 1900. Personal Argentina.
When i go to WCDMA only find Movistar. That they say works on the Band V. So i think my phone is only working on Band 850 and maybe 2100 also because i bought on Hong Kong.
Anyone can check with IMEI or something?
Is there any way to change the Band to Band II?
Thanks a lot
I need an answer please !! :good:

According to gsm arena, the n7105 is not compatible with 3G the 1900mhz band.
3G Network - HSDPA 850 / 900 / 2100 - N7105
4G NetworkLTE - 800 / 900 / 1800 / 2600 - N7105
I know that it's not an easy suggestion but have you considered changing providers?

N7105 can only support 850/2100mhz band,so if there is 1900mhz 3g band in your area, it will be a problem
