Galaxy s 9000 with tmobile 3g usa?

Anyone here have the galaxy s 9000 euro version working with tmobile 3 g in usa?

I'm also interested in that. I'm about to buy a galaxy here in EU but I'm moving to california soon. There should be no issues however since the galaxy is a quad band phone

I looked into importing a HTC Desire from Tmo UK for use here on Tmo's US network -
Tmo europe uses 2100 band for 3g, Tmo US uses the AWS IV band (1700/2100) for 3G - i did a little more research and found that 2100 was the download side and 1700 for upload - and as Tmo here in the US told me my Tmo MyTouch 3G would work fine in europe, i figured i'd be good to go - maybe only have 3G speeds on the download side
got hold of a 2nd level tech at Tmo and he 'xplained it down't work that way - if the Tmo US network doesn't see both freqs (1700 & 2100) it will switch me to 2G data speeds
so answer is, it'll work for phone calls, but data speeds will be limited to 2G

I can confirm, I did a lot of digging myself and found the same thing. I'm from the UK but living in the US for a year or so. I was going to get a Galaxy S from ebay but realised they didn't have the 1700 freq so wouldn't get 3g with T-mobile over here ion the US.
My Iphone 3g from the UK only gets edge data transfer speeds here in the US as it too is missing the important 1700 freq...

Finally figured this out too after posting questions in different places. Found this article which had a very detail explaination.

One thing I'm wondering is if it is possible to flash the android radio version from a Vibrant on to an international Galaxy S to enable Tmobile AWS?

that question is best answered by someone far more knowledgeable than i am in software and android OS

i want 3g
I just recently bought the unlocked galaxy s to use for when I study abroad in Germany in the coming months. However, I am experiencing the very issue raised in this thread and have been searching high and low to find a solution to change the radio frequency to include both 1700 and 2100. Hopefully, flashing the firmware from the vibrant to the unlocked galaxy s will work, but I'm not experienced enough to even know where to start.

Samsung Galaxy S I9000 works with T-mobile US?

I would like to know if this version work 3G with T-mobile US , i want to get it from clove.co.uk but i want to make sure first if it works with T-mobile US 3G ....
Thanks

clove sell them with 3g frequencies of
3G Network - HSDPA 900/1900/2100
t-mobile usa uses 3g on
1700 and 2100
so you would be missing a band, doubt it would be any good for you.

no 3G without the 1700 band
tmo usa uses 1700 upload and 2100 download - i foolishly thought i could survive with just 3G on the download side - luckily someone that had tried it with a HTC Desire from Tmo UK told me it didn't - if tmo usa network doesn't see both sides of the AWS IV band (1700 & 2100) it will limit the connection to 2G speeds

that's why they call it a "band". Without both frequencies that are bound together, it aint gonna work.

Thanks guys for the answers. I really like this phone but I don't want to get the one in tmobile, because I want Arabic support and I don't know if vibrant accept I900 0 Roms . If it does of course I will get it . So my q now is the vibrant accept I9000 roms or not ?
Thanks again

US T-Mobile's 3G freq vs the rest of the world?

Anyone getting the T-Mobile version tomorrow? With CDMA not SIM capable, and AT&T version still up in the air, I think I'm probably going to get one tomorrow!
I've got question regarding T-Mobile's werid 3G band tho. I think Samsung listed T-Mobile's version as AWS 1700/2100. I know 1700 is weird, but is that AWS 2100 same as the 2100 band that the rest of the world use? Sorry it's my first 3G T-mobile device, and looking on wiki or google is just kinda vague

2100MHz is the band used all across Europe as well as large parts of Asia.
So, yes, the T-Mobile one should give you 3G capability in other parts of the world, though if it's locked that may open up other issues.

I had a TMo US G1, and it worked fine on 3G when I returned to the UK. The converse was not true of my TMo UK G2 (HTC Hero), which would only get Edge in the US because it did not support both bands of AWS (1700/2100).
So, I see no reason why a TMo US shouldn't work pretty much everywhere else in the world where 2100 3G is ubiquitous.

Dave

Cool thanks, i guess that AWS threw me off. I thought there were a regular 2100, and then T-Mobile's AWS 2100

Actually you're a bit off. Tmo's 3G runs on AWS 1700/2100 band which is not the same 2100 *frequency* as the rest of the world. Tmo uses 1700 for downloads and 2100 for uploads, so both bands (aws/band IV) are needed.
Now Europe (and rest of GSM world) use straight 2100 band for 3G but the exact frequency is not the same as Tmo's.
Basically a Tmo Galaxy Tab will only get you EDGE outside of the US. An ATT Galaxy Tab will get you 3G in the US and the rest of the world (as long as it's sim unlocked, ofcourse).

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).

I thought the galaxy tab is quad band, so you can simply swap your sim card with another european carrier and it should work on thier frequency
Am I wrong?

You're right for 2G, not for 3G

So getting the unlock code for tmobile device and putting AT&T sim card will not give me 3g connectivity (using AT&T network)?

No, because it doesn't support the 850 or 1900 MHz bands.

It will not. Pls do some more reading on the subject. There's a very good writeup on it in these forum. Someone explained it better than I've probably done. If I find it I'll link to it.

One could say the same to you.
This is a link to T-Mobile US's support forum, in which someone has had it confirmed from T-Mobile themselves that all devices designed for their network have to be fully compatible with the 2100MHz band, meaning they will give you 3G capabilities in Europe.
Your previous post in which you claim that the 2100MHz band that T-Mobile use is not the same as the 2100MHz band the rest of the world uses is nothing short of ridiculous.
If the band T-Mobile used was different to the one used in the rest of the world, it would not be described as 2100MHz.

Sorry, but as I already said earlier in this thread, my T-Mobile US G1, which is an AWS device, worked perfectly well in the UK with full 3G. Similarly, I know of people who bought TMo Nexus Ones in the US, and these all worked fine in the UK.
That's not to say there isn't some subtle difference which not all chipsets can cater for, but it is certainly true that many TMo US handsets will give 3G capabilities in Europe.

Dave

The normal UMTS 2100 is called "Band I" and t-mobile's AWS is called "Band IV":
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The AWS 3G module has already 2100MHz support, so there is no additional hardware necessary to support Band I as well. Theoretically it could be disabled, of course, but then T-mobile wouldn't be able to charge you an arm and a leg if you were to roam outside of the US

[Q] Unlocked Nexus S with 3G network

I want to get a Nexus S for myself, the unlocked without contract one, because I would like to use it in my home country (Malaysia).
So I would like to confirm one thing before I proceed:
I saw this from BestBuy forum FAQs:
Will an unlocked Nexus S work with carriers other than T-Mobile?
Yes, but it won’t run on 3G with all carriers. Speed and power will be reduced on non-3G networks.
Is that means that even though Nexus S did support the 3G band of my home country, it won't run on the 3G network?! Means that I can't use the 3G in my home country?

Anyone have answer for this? Anyone tried buy N1 and got the 3G working in country outside US?

gotta be 1700/2100 MHz i believe

Wont' work. Malaysia uses 2100mhz band for 3G.
The Nexus S on T-Mobile uses BOTH 1700/2100mhz AT THE SAME TIME for 3G.

It will work fine since the 3G band in Malaysia is 2100MHz and the Nexus S supports those bands.
I had the Nexus One (T-Mobile Version) in Thailand and it worked perfectly fine on 2100MHz 3G. My N900 worked as well.
Don't listen to nxt or slowz3r they have no idea of what they are talking about.

You wont have a problem with most 3g phones in Malaysia - most of the rest of the world uses standard frequencies and the nexus s and nexus 1 work just fine.
If a phone works in Europe then it'll be fine in malaysia, and indeed most of the rest of the world.
Most of the noise on here is from people in the US where there are some weird frequencies being used... you can only use 3g on T-Mobile there -at+t uses different frequencies, and sprint and Verizon use a completely different technology.

Thank you for all the useful replies!
Got the answer. Thread Closed.

T-Mobile HD2 on Australia 3g?

Hello,
I want to buy a T-Mobile HTC HD2, one question, will it work with Optus 3G Network as I've heard that it does not work with AT&T 3g so I'm wondering will it work with any other 3g provider OTHER than AT&T.
If it does work will it have any compatibility or performance issues?
THanks.

Im pretty sure my HD2 worked with the Optus network this afternoon.
Perth. WA.

I was wondering if there will be problems if the T-Mobile can't use the 3g bands that Optus uses.
It seems that Optus uses HSPA 900 and 2100, not sure why 900 and 2100 is used, now here are the specs for both the HD2's T-mobile and non T-Mobile :
http://www.gsmarena.com/t_mobile_hd2-3228.php
http://www.gsmarena.com/htc_hd2-2957.php
As we see the T-Mobile does GSM 850/900/1800/1900 and HSDPA 1700/2100, and the non T-mobile can do HSDPA 900/2100, Telstra one does HSDPA 850/2100.
Now I'm wondering if the T-Mobile (or Telstra) can't do HSDPA 900, what problems will I see?
Once again I would like to use these on the Optus 3G Network.
Thanks,
BTW Dave, is yours a T-Mobile version.
