My provider (Telstra AU) uses UMTS 850 Mhz for their NextG network.
I've always wondered why my coverage was garbage.
Now I realise that my Atom Life has no access to the 850mhz band - only 1900 and 2100.
Is this a hardware level restriction, or are there updated ROMs etc that will allow me to use the 850mhz network?
Anyone has the answer to that?
I too like to know if there is a way to enable the 850 band for either 3G or GSM.
I have an old duel band phone that i was able to turn in to a quad ban with just a new flash, so that makes me wonder if it is possible with this phone as well.

Would be nice because with 850/1900 umts you would also be able to use it with AT&T and Rogers in NA.

Hello All,
I recently bought a 3G Cingular service plan with unlimited data. I have a Qtek 9000. Do you think I can use it in markets where cingular offer 3G to make use of video calls/ high speed internet etc?
Thanks,
Gilbert
The Universal only supports UMTS 2100 Mhz not the Cingular 1900Mhz based system.
Bummer. This is a sad day in the history of sad days :evil: Ok but I can still use my unlimited GPRS to surf the net, right?
With the new devices planned for this year, are they planning multi UMTS bands along with GSM quad/ multi bands?
Thanks,
Gilbert
You can only use GPRS on the 1900 network. If you're outta luck there are no 1900 masts in your area (only 850) and it will be a really, really sad day and you wished you had bought a quad band device etc...
There is also some rumour that US UMTS will not use the 2100 band - that would be a real bummer.
I remember in the US when the Jam came out there was two radio versions. One for the US, I cannot remember the bands and another for the rest of the world. But I clearly remember that it was a software issue and not a hardware as the software could change the frequency to match your requirements.
Does this exist for UMTS?
Regards,
Gilbert
this depends more on the antenna design, and how far away the bands are. The radio tuner should not be the issue.
Thanks for the reply. Does a software band switcher exist to do the switch to 1900 UMTS from 2100 UMTS?
Thanks,
Gilbert
The Truth
USA uses the 2100 frequency for US satalites this is why Cingular does not support the 2100 frequency. They will never have 3G on 2100, FCC crap the only thing we can only hope for is a hardware upgrade for the antenna but I doubt it. GPRS only works on 1900 so who ever told you the 850 crap doesn't know. this is why you can get voice calls in certain area but no data + if you only had an 850 towers you wouldn't beable to make a call scince you don't have that band on your device. I don't think there would be a way to hack it to use the 1900 mhz frequency because it would take a really smart developer that can do a lot more than registry tweeks to wirte a relay to the 1900mhz antenna. sorry guys.
I did a lot of reading on this last night. Rumor is Cingular is to start using the 1900 band for incoming and outgoing and then add the 850 band latter since the 2100 band is not available.
just a rumor
It is just a rumor. They already have 3G on 1900 and that's it, 850 is old technology if anything the 1900 tower are going to be eventually replace the 850 tower. Trust me, I live in LV where 3G is all over, GPRS, and 3G is only on 1900mhz if you look at the coverage maps for gprs vs the cellular coverage map you'll see what I'm saying.
X1 has -
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
ATT - is
850/1900
why cant i connect to 3G here in the US ?
You may have a X1i. Which has 3G bands 900/1900/2100 and you live in an area with 850MHz 3G.
Since the X1a, which is the model with the specs you posted, hasn't been released yet (apparently ships today according to Sony Style), I doubt you have the right Model. You have the X1i.
No i have
GSM 1900-850 and UMTS 1900 850
says so in my settings.. but i dunno
it reads X1
not X1i
and has an FCC ID under the battery where the S/N is
Did you get it from US? Or overseas? Europe Asia?
If not from US, then its X1i version.
And I think the X1a was just released today, right?
Sorry, but you probably have the X1i, unless you got a very lucky prerelease of the X1a which has not shipped yet. There are numerous posts that are confirming that there is only 1900 on the X1i and not 850. This means that it will work in some 3g areas, but not all.
The X1i lists all of the bands in the settings menu despite the above info. It's a bit misleading, but even though the software lists both, it doesn't always mean that the hardware supports it.

Hi Uber,
You have an X1 also known as X1i
The UMTS is 900/1900/2100
Europe uses UMTS 2100 so you select setting 1= 1900/2100
USA AT&T uses UMTS 1900 in some areas, while in other areas it's 850
The reason your Xperia also have setting 2 as UMTS 850/1900
is for when you travel to a UMTS 1900 country like parts of USA
But since your device doesn't have UMTS 850
it won't work in a country with UMTS 850 like
Australia, Canada and some areas of USA.
Where in USA are you located?

im using AT&T here in the los angeles area. i got 3G no problem indoors as well as out. so hope this helps others. also...you might have to disable the hsdpa/hsupa in the advanced network. if you dont, you get the "H" symbol...which i heard is a little bit slower than 3G. hope this helps
Hi vicsingh71
Sorry to tell you but that is wrong as 3G is a max speed of 384kbps whilst HSDPA is max speed of up to 7.2mbps for download and i think HSUPA is 2mbs for uploading. Anyway super fast Data also called 3.5G is what these two are and they are both much faster and a better service then just 3G.
Marc
i also have a x1i purchased in the uk. i live in Los angeles and the 3g works perfect! The only reason sony made the x1a is to be able to sell it in the us. the x1i uses a qualcomm prossesor that is in litigation with nokia here in the us, so it cannot be sold here. that is why the downgraded the chip for the x1a. my advice is to get the x1i
Hi .. I was searching the forum because I want to purchase an HTC HD2 T9193 which, I know, has the 850 - 2100 Mhz band. But I found on the net a vendor who offers the HTC HD2 850 - 1900 Mhz band, is this right ?
On the other hand, if there is not such HD2 with 850 - 1900 Mhz band, the one with the 850 - 2100 band will pick up 3G in Canada ?
That model (850 / 1900) was supposed to come out (for AT&T most probably), but it has since been cancelled.
I'd be careful if I were you. You can find more info about it here
The Telstra model (T9193) supports 850 / 2100 MHz like you said. You'll need to check with your service provider if they support 850.

Yes. You'll need to check if ATT supports the 850mhz band IN YOUR AREA.
I'm in a North Shore Suburb of Chicago area and have excellent reception with my T9193 in the area. There are 3 dead zones I've found so far that repeatedly drops calls using the HD2's 850mhz band exclusively. Other unlocked phones I've previously owned that used the 1900mhz band exclusively did NOT drop calls in these areas however. Other than that, reception has been great. It's been reported that ATT is "supposedly" moving their entire network to the 850mhz band exclusively by end of 2010. I'm doubtful they are on target for this date given the number of cities still without any 850mhz support.
T9193
Hi guys ...thanks for your responses. Well, I know that the most important service providers in Canada (Rogers, Telus, Fido) transmit 3G in the 850 - 1900 mhz band. I suppose I will not have problems whether I use the T9193
hey fellas.
let me explain a bit.
i have a optus galaxy S, but i am with telstra.
as far as i know optus 3G is 900mhz ( or whatever it is, 900 something )
and telstra is 850, therefore telstra 3G wont work.
i put my mates optus card in my phone last night and it worked fine, 3G all the way.
is it somehow possible for me to get 3G on telstra? a diffrent baseband thing or something?
thanks fellas! really really hope someone can help me out here.
optus is 900/2100 and telstra is 850/2100

Your obviously near a 2100Mhz enabled tower, but, if you roam out of the 2100Mhz range (mainly capital cities and large regional cities) you'll only get a 2G signal on your phone with the Telstra SIM.
Your Optus phone is hardware set at 900/2100, you can not access the 850Mhz 3G band.
I don't think Optus had their own version of Galaxy S. It should be the international version.
GSMarena shows the specs as:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
Seems like there is no 3G for 850?
Telstra has their own I9000:

Try this and see if it works:
http://forum.xda-developers.com/showthread.php?t=893082
Edit: I highly doubt if it'll work, since I can't see any documentation of a stock SGS being able to do 850MHz and HSPA+ (which NextG runs on) at all. It seems, as in most cases, Telstra gets different phones that runs only on their network.
If you enter the correct Telstra apn details you should be able to get 3g 2100MHz coverage but you will not get NextG 850MHz coverage. It is harware/radio related and flashing a 850MHz firmare like that used by the I9000T or the I9000M will not change anything.
If you need Telstra's or any other Aus provider settings you can find them here: http://ausdroid.net/apns/

After further reading it seems sxi200 is correct, the radio on the normal I9000 doesn't have the required hardware to connect to the 850MHz band. Earlier I was thinking the phone would all have the same radio that covers all bands but has the 850MHz band locked out.
This might interest you, but when the time comes you probably would already have a new handset then.

Would anyone happen to know-
if I buy a Galaxy SII from Europe, would it work in the US? specifically with T-Mobile?
As I understand it, yes. But only with the EDGE network. 3G and 4G frequencies are probably different. Could be wrong.
This is the band T-Mobile USA uses: AWS, or UTMS. I don't think it would work, seeing the Galaxy S II's specs. I believe it has to be capable of both. I think best case scenario, it works like an unlocked iPhone and you can get Edge, but not 3G, much less "4G."
While the Galaxy S II supposedly works in both bands, I believe that in order to fully function with T-mobile USA's network it has to support both at the same time. Like I mentioned before, that's called AWS, and it seems to me it would have to be explicitly written in there as a supported band.
So what other carrier would support this device?
btw, thanks for the info!

Completely wrong.
At&t uses 850 & 1900 for data.
The SGS2 has 850, 900, 1900, and 2100.
It should work on t mobile, but I don't know the network bands off the top if my head.

T-Mobile uses 1700 so you wouldn't be getting 3G.

I had to post because I saw alot of misinformation.
The GS II will certainly work in the United States.
It is a Quad Band GSM phone w/ EDGE data. It will also work on the 1900 WCDMA 3G band. At&t, Telus and Bell ALL function on the 1900 WCDMA band.
So yes the GS II will work with 3g on the 1900 WCDMA band here in the states and in Canada. You only need one 3g Band either 850 or 1900 will do. Best to have both so check your coverage area. I have a Galaxy S and have constant 3.5G HSPA signal with 1900 WCDMA only band.

I looked up the network bands. This is how it is:
Voice/calls/texts/etc. will work 100% fine on both of them.
As for 3G:
SGS2: 850, 900, 1900, 2100
AT&T uses 850 and 1900. 3G will work perfectly.
T-mobile uses 1700 and 2100. Apparently their network is retarded and you need both.
Sent from my Captivate.
Wrong again
T-Mobile uses 1700 paired with 2100 commonly referred to as 1700. A phone with 2100 will not work on T-Mobile... A phone must have 1700 to work on the T-Mobile USA 3G network anywhere in the USA. This phone will work on the 2G network and IF T-Mobile has any 1900 3G towers it could connect to those (I'm not aware of any at this time).
