I would love to be able to use this amazing phone in on T-Mobile in the US without crippled data speeds as well as seamlessly on voice. Anybody here have experience with this new phone on this network?
ST18a is supposed to be for AT&T, but I speculate that ST18i might be better for T-Mobile US due to 900/2100MHz. 1700MHz is missing though. I also don't know how accurate this is:
hxxp://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
Just today a T-Mobile Tier2 told me all I needed was 900 / 1800 / 1900MHz for 3G, and 1700 and 2100 for 4G.... so I am left very confused.
Note even access to 3G via roaming on this phone would be acceptable.
just to relieve you from misunderstanding, the ray is not 4G, and the bandwidth 2100 is 3G, and is used mostly in europe and asia pacific, which ever version you get, the umts is available in 5 bandwidth and are all 3G
Hi kms108,
What's your experience with the ST18i? Are you using it in the US? Possibly on T-Mobile?
Thanks!
i have the hong kong version, which is unbranded and using it in hong kong.
i'm liking it very well, just the right size to hold, not a android phone on the market to match it in quality, specs and size wise.
Xperia ray DOES NOT support 3G from Tmobile.
I own the device and I learned it the hard way.
Although ray supports 2100 MHz, the only device that can access Tmobile 3G is the one with BOTH 1700/2100 MHz. It is because Tmobile split both frequencies: one for download and the other for upload.
While for other carriers your phone will work in 3G if it supports either one of the frequencies, however, Tmobile is different.
Having said that, almost ALL of the unlocked phones in the market won't be capable of accessing Tmobile 3G.
If you wish to access 3G, the only carrier that will work is AT&T.

Which version, ST18a or ST18i, did you buy? See following:
hxxp://androidforums.com/sony-ericsson-xperia-ray/443709-3g-4g-us-t-mobile-using-st18a-st18i.html
Mine is the ST18i.
Well, neither version will support Tmobile 3G.
ST18i UMTS HSPA 900 (Band VIII), 2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
ST18a UMTS HSPA 800(Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
Here's the specs from the manual.
Since both are missing 1700, neither will be capable of receiving 3G from Tmobile.
AT&T
What irony -- maybe the AT&T acquisition of T-Mobile will have some benefits after all, especially those who buy the ST18a...
This wikipedia link confirms your experience: hxxp://en.wikipedia.org/wiki/T-Mobile_USA#3G_upgrade
The Xperia X10 had 1700, too bad Sony eliminated it.

Title pretty much says it all. What's the real story on the the 3g frequencies? Nokia's site indicates it's quadband 3G, but yet many of the stores seem to indicate that it's tri-band for 3G. I would like to get one for use on ATT, but I definitely need 850MHz 3G since that is the predominant frequency in my area.
Anybody? What's the real answer on this?

This only adds to the confusion (No WCDMA 850)?
Thanks for the responses everyone. I think they just add to the confusion on what the real answer is, or Nokia is producing multiple models with different frequencies which I've seen referenced elsewhere.
I might just hold off for the 900 or wait until CES in January where they are supposed to make their big splash for the U.S. market. The render of the Lumia 900 that hit wmpoweruser today certainly looks nice if it's true. I wouldn't mind a slightly larger screen if it doesn't make the device too large. Some of the current phones border on mini-tablet size!
I know of two types of Lumia 800's and you can differentiate them via their FCC identification.
The European edition, FCC ID: LJPRM-801:
GSM/EGSM : 850/900/1800/1900
WCDMA : 900/1900/2100
The North American edition, FCC ID: ...RM-819:
GSM/EGSM : 850/900/1800/1900
WCDMA : 850/1900/2100
I really wish Nokia would fix the data on their web pages. I ran into this a few years ago with another phone I purchased from them where it was advertised as having U.S. bands when in fact it did not. Thanks for the info everyone.
Agree 100%. When i bought my phone, the lumia was advertised as:
WCDMA: 850/900/1900/2100
Many sellers have since correctly identified which bands the phone supports, but some still falsely advertise both 850 and 900 bands being on the phone.
When my Lumia 800 arrived and I could only get Edge/G service, I did some research and I was slightly disappointed. Luckily I work and live in a Wi-Fi zone, so that is my primary data connnection.

You too, huh? I was curious about Rogers. I find that 2G isn't the end of the world.. Only shortcoming are media rich sites, otherwise they still load up quickly for me.
The only thing I really would have missed on 3G is mapping and navigation, but the non-data GPS and preloaded map feature has completely eliminated that concern.
Rogers here in the 'Peg. I'm in love with it even though the primary service around my home is Edge/G. However, since I wrote that piece above, I grabbed the "Nokia Network Setup" application from the marketplace and now I can get 3G around my workplace.
Here is my situation at the moment. I'm currently in the US using At&t's network through straight talk. I purchased the Nokia Lumia 800 the UK version which is LJPRM-801. It clearly states that it supports WCDMA 900/1900/2100. Which I suppose are really meant for the UK or Europe. When I purchased the phone from the seller he clearly stated it was lock and he got it from Orange UK. Which I assume is locked as well. Surprisingly when I received the phone I inserted the Sim and it registered perfectly fine. I get voice AND data. I figured it may possibly be using the 1900 band for data. My main thoughts about this UK version is it may possibly have the 850 band included but not listed on the box for regulation concerns. How would I go about and truly testing it out if it does support 850 band?
You can't really, short of going to an area you know uses soley 850Mhz 3G, and not 1900 as well.
I dont see the reasoning behind manufacturing two different phones, My thoughts are they could have just disabled the band with a simple firmware. Has Anyone truly tested this? Any though on getting a different firmware version of the Lumia 800 on this UK version seeing if it would enable the 850 band.
Me too I purchased one from Clove.co.uk. On the box it stated 900/1900/2100 for 3G but I have 3G. Maybe I have a 1900Mhz station near my work. I will do more tests tonight.
Does an app exist to know the current band of 3G connection?
I've called Nokia while in Germany and they said that they only produced quad band Nokia lumia 800's

When you say quad band are you referring to 2g or 3g? because we know it's quadband 2g, but whether it's quadband 3g is the question.
So I have used it on 3 different locations here in Montreal on Rogers and I always got 3G. I don't know the band used by Rogers. I found several references but not definitive answer. I have the Lumia 800 Model 801.

I'm in Germany right now and don't have the box. I don't remember if it had the cell bands on the box. I know I got hspa on AT&T and I was happy.
Want to get the s3 but want to make sure it works with TMobile.
No, you will only get edge speeds, no 3g.

Sorry I pressed thanks instead of quote.
No, its nothing to do with the modem. If it was, people all over the world would be buying devices from other countries.
The fact is the international GSM version only works on the frequencies its designed to work on. This is a hardware limitation and no amount of software will resolve that.
International frequencies are different to USA frequencies and as such, devices not designed for the USA will not work to their full potential in the USA.
UK (international) uses 900 Mhz/1800Mhz GSM/3G where as USA T-mob uses 1900Mhz GSM and 2100Mhz 3G.
Because the International GSM quad band device is:
850/900/1800/1900 MHz...
The GSM and 2G function works on 1900 (T-mob) but has no way to use 2100 for 3G as its not physically possible

yes i agree for international version.. but if you read closer i DONT have the international version but the att version.. and as far as i know all the usa versions are the same with just diff. modems.
The international version will work in areas where T-Mobile is refarming 1900mhz to 3G. However this is only happening in parts of the coasts. I'm using it in Ohio and getting EDGE only. That said, it isn't too bad.

Erm, it's being tested in some coastal areas, but the 3g/hspa+ over the 1900 band is slated to go live on the majority of the network by the end of the year.

I purchased a Tinji i9300. I have been working on this for over 3 weeks. I have no service with T-mobile. It recognizes my SIM card as T-mobile. In Engineer Mode, my bands are, EGSM900, DCS1800, PCS1900, GSM850, WCDMA-IMT-2000. I have tried numerous ROMs (stock and custom) and have rooted the phone. I have changed the IMEI. No service at all. Any thoughts? Band issue? T-mobile issue? Possible solution? **** out of luck? :crying:

I'm curious too. I refuse to buy the Lumia in black off of Rogers and the AT&T model is likely to be unlockable like the 900 was.
Add one more request to that. I'm not eligible for an upgrade until next year, so I'll be paying full price for my Lumia 920. I'd rather get the unbranded version if I go that route, since I won't have AT&T blocking any updates that they're notorious for doing.
Hopefully someone will answer this, that att logo looks ugly, and they block updates, so I need to know this, and two others too.

Unless Nokia did something extraordinary, I really do not believe they will release the phone with 9 LTE bands.
The original specs was PentaBand LTE and the AT&T LTE Bands were missing. Meaning the international version will NOT work on AT&T's 4G LTE.
Please see my post here for more information.
Here's an interesting article about unlocked/international phones. I found it pretty informative.

Make a simple answer yes or no? The att lte phone have lte 2100 so does the international lumia 920.

It seems like the Samsung Galaxy Alpha has all the necessary bands to be used with AT&T in the US. But does anyone know for sure? If Samsung takes too long to release this in America can I buy the UK version and use it in the US?

Bump. I have the same question.
GSM Arena says this about the device:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 800 / 850 / 900 / 1800 / 1900 / 2100 / 2600
If what wikipedia says, AT&T uses the following frequencies:
2G: 850 / 1900.
3G: 850 / 1900.
4G: 700 block B (main frequency) / 1700 AWS / 1900 / 2300.
So, if I read correctly, you can use the international Alpha for 2&3G, but for LTE, you are covered only by one LTE band, 1900, and this being not a main frequency, won't have good coverage everywhere, I think.

Yes. If it was me to make the decision, I'd want my phone with an unlocked bootloader, HSPA+ is good enough speed for me.
Though, practically, I've never tested LTE in my life, until recently we didn't have any 4G networks.

I bought an unlocked international/Euro Galaxy Alpha SM-G850F at the London Samsung store... Installed my USA ATT SIM and have no prob w. calls or H or H+ data but can NOT get LTE band in the USA on either ATT or TMO even though the device seems to have the right bands for ATT or TMO LTE. On advice from an ATT Wireless store manager, I updated my APN settings to match ATT setup but still did not get LTE. FYI my H+ is quite fast for most purposes but I want LTE. Hope that answers your question.... Mine is how can I get LTE???

I am trying to solve this also.
I think that the Euro Version with the Exynos does not have the proper LTE Bands for North America LTE.
But the Qualcomm version does, though not sure about
TMobile.
I am looking at this from Canada GSM for $ 549. Factory Unlocked with following Bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G & LTE 2100, 1900, 1800, 1700, 2600, 700, 850
Obviously for AT&T you just buy theirs.
I have read that the EXYNOS versions do not function in North America on LTE.
With all phones it seems that you must be very very
Specific about Model Numbers including Suffixes etc.
Especially SAMSUNG loves to make 24 versions of ALPHA, 50 versions of S4 etc.
Frequency Bands are a real WTF for amateurs like me:
For example are there TWO DIFFERENT 1700 bands, one for4G LTE and one for 3G , HSPA + or are they the SAME BAND with dual usage ?
In example ABOVE the Alpha Factory Unlocked Canada GSM @$ 549.
IF used for TMobile the LTE Bands look fine, but the 3G
1700 Band is not there. Will 3G merely use the 1700 LTE
band or does the SOC ( QUALCOMM) need to have
allocated the 1700 band for dual usage LTE and.3G
?
