X1 not working with USA 3G ?

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.

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

HTC HD2 T9193 850 - 1900 Mhz ?????

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

3g in Argentina

Hi,
I'm from Switzerland and I've to buy a new phone for my father that lives in argentina... the problem is that here the 3g frequencies standard for phones are 900 & 2100...
What are in argentina, I've seen that are 850 and 1900....
The only phone I've found for acceptable price is the samsung galaxy S that has 900/1900/2100 (no 850mhz!!!)... will this phone work???
last question is... if i've only quadband gsm and 900/2100 3g can I use internet also with slow velocity?

help please

nothing for now?

Motorola Defy ?
3G Network HSDPA 900 / 2100
HSDPA 1700 / 2100 or HSDPA 850 / 1900

Have a look at GSMArena Phone Finder - here you can tick the frequencies you like. The only phones that offer quadband UMTS for now are latest Nokias (for example C7, E6, X3-02) and Samsung Galaxy SII. If you buy a quadband GSM and 900/2100 UMTS phone you would be able to use only GSM in Argentina.

Will Samsung Galaxy Ace 2 from UK work in India?

I was looking to buy my mother a Samsung Galaxy Ace 2 from a long time. Waited for long enough for it to release in India. But looks like it will not be. Now I am considering getting one from the UK. Will it work with 3G in India without any problems? I checked GSMArena for its bands. Its a Quad-band phone for calls and Edge. But what concerns me is its 3G bands. It says HSDPA 900 / 2100. I have a Samsung Galaxy S II which says HSDPA 850 / 900 / 1900 / 2100. Despite the 1900 band missing in the Ace 2, will it work fine?
Another startling fact that I found is Samsung Galaxy Ace and Samsung Galaxy Ace Plus also have HSDPA 900 / 2100 listed in the Samsung India website /GSMArena. And these phones are popularly sold as mid-range smartphones all across India (Hence I assume 3G also works flawlessly on them). Has anyone already got a phone from UK or elsewhere with similar bands and seen 3G works ok here? Please help me take a decision.

It will work fine. The bands seem to be compatible with all of India's carriers. That includes the 3G bands too.

Thanks iOSToAndroid. Despite the missing 1900 MHz band, will it be fine? I read in a few places that 1900 MHz is used for upload?

1900mhz is majorly used for both ul and dl, but majorly upload. But in reality, your mom will probably not heavily use the internet, so I guess the 2G bands would be good fir her too.

And 3G coverage in India does not seem to be great, too

[Q] Noob question about GSM and Quadband Frequency

I was thinking about buying me a open line LG Optimus G2 then bringing it to japan, and give it as a gift. Ive been doing some research on the net, and it says that Japan doesnt support of use GSM frequency band, because they are not using 2G or something? Can someone please enlight me or explain this to me. How this things work, because i had already tried, and called the site here in norway that who are selling it. They told that it supposed to work but, after i have done my search on my own, i really doubt that what he told me. lol
So can somebody please or tell or can confirm to me that working or not?
These are the frequency band of LG Optimus G2: 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 900 / 1800 / 2100 / 2600 / 850
