I have a phone that supports 3G 850/2100Mhz. (GSM 850/900/1800/1900MHz)
I am using it in Europe right now and i'm travelling to the USA soon. (long time)
I have done some research and the providers over there use:
- AT&T/Sprint/Verizon uses 3G 850/1900
- T-Mobile uses 3G 1700/2100.
Do I need both frequency's for 3G OR is 850 (for at&t) etc. / 2100 (t-mobile) enough to use 3G.
I will stay in L.A and both frequency's are covered in LA. (?)

I want a 3g enabled smartphone/PDA for t-mobile, not the G1 dont like it. T-mobile 3G uses bands 1700 Mhz and 2100 Mhz right? So if i buy a phone that supports HSDPA 2100 Mhz will it work on the t-mobile 3G data network?
t-mobile is a gsm network though, so i don't know that an hsdpa phone would work with them (first of all no sim slot)
tmobile's 3g is new and not fully released so it would be difficult to find a phone that supports their 3g (you won't find anything but the g1, and you couldn't unlock a phone from att to support there 3g because the bands are different)
This is my understanding, but if i am wrong you guys can correct me
phones that are from htc that are in europe and asia..for example, the htc hd2 and hd.. do they work with cell phone providers like at&t? here are the specs for the htc hd2:
Network -
HSPA/WCDMA:
Europe/Asia: 900/2100 MHz
Quad-band GSM/GPRS/EDGE:
850/900/1800/1900 MHz
I highly suggest you read the specs and find out what band it supports and cross reference it with the bands they use in the US (wikipedia has the answer to that)
totally wrong place for this, but I'm not a mod so...
Any GSM phone supporting quad-band or tri-band with 850 (you need 850MHz at least, 1900 helps in some places) will work on the network. Many phones support this for gsm/EDGE. Very few phones support this with 3g.
If you want to use att 3g, look for a phone with 850/1900MHz support on "UMTS", "WCDMA", "3G", "HS(D/U/blanks)PA", etc. Basically, if it is marketed for AT&T, Rogers (in canada), or some south american providers (claro?), you'll be good.
Most phones will support 2g, though.
EDIT: As an example, based on those specs you list, the phone WILL work with EDGE, but not 3G/HSDPA.
All correct from poly_poly-man + Telstra in Australia uses the same 3G band as AT&T so there you may go shopping
Hey guys I just wanted to get some info on what phone will be possible for importing.
I live in Australia and am contemplating to a smartphone from US and A (why do they get the best phones the earliest?). But the issue is that I am still in my contract (Optus/Virgin). I have little idea about the different GSM radios, but still unsure.
(I was planning on importing the EPIC 4G but, like the rest of the world, we don't use CDMA). Now I am contemplating to import the Motorola Atrix 4G (I am pretty certain this wont be made available here).
Would AT&T's services work in Optus (with voice and data/voice only/no support)?
How could I unlock the device if I were to purchase it? (carrier only/manufacturer only?)
I hope this thread can be useful for other members.
AT&T devices work in 850 frequencies for 3G networks, check with your local provider, as for unlock you can find them all around the WWW from 8 to 30USD depending device.
Thanks orb.
Here's the situation, I'm in metro-area on Optus connection.
1. Telstra (this company is equivalent to AT&T in USA)
3G UMTS850 (Australia wide 3G network, aka NextG)
3G UMTS2100 (3GIS Network shared with 3)
2G GSM900
2G GSM1800
2. Optus (this company is equivalent to Verizon in USA)
3G UMTS2100
3G UMTS900 (rural network)
2G GSM900
2G GSM1800
3. Vodafone Hutchison Australia (This company is equivalent to T-mobile in USA)
3G UMTS2100
3G UMTS900 (rural network)
3G UMTS850 (limited metro network)
2G GSM900
2G GSM1800
Would the Motorola Atrix 4G be compatible with my plan?
If not, what would it be compatible on?
You may chack the device bands, from what I found:
2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA 850 / 1900 / 2100
Reference
If you ask me what would I choose my answer is an HTC branded device, just check what model you want and get the band specs.
This is a great data base site.
Let us know what you got!
Here is a bit of a reference for you. It has phones for your frequencies, 4 inch screen or bigger, Android and a 5MP or more camera.
You can look at any phone with the "Phone Finder" button.

Infuse 4G never sold in Malaysia and Thailand officially...
Works well in Malaysia but 3G is not working in Thailand.
Anybody knows the solution ?
Should flash specific Modem ???
Thanks, guys...
1. What 3G bands are present there on the network you are on?
2. Are any of those bands present in Infuse?
Even within US, T-Mobile SIM in Infuse won't give 3G 'cos of bands incompatibility.
ic...
Will check and report here again,
Thanks, Dud...
Hello pal,
Infuse only support 3G - HSDPA 850 / 1900 / 2100 but Thailand Providers (AIS, DTAC .. and others, I am not sure..) only support 3G / HSDPA 900 / 1900 / 2100..
So I think no matter what Modem you flash on Infuse, cannot use 3G in Thailand.., I think.
I also found out something weird is,
Almost every Samsung phones support HSDPA 850 /900 / 1900 / 2100 EXCEPT INFUSE 4G.
So this is because of bands incompatibility as diablo009 said...
Thailand Providers Truemove and DTAC support 3G band 850 MHz
( 3G UMTS/WCDMA , 3.75G HSPA(hsdpa)/HSPA+ )
Modem UCKL2 works fine.
Hi guys,
I'm looking to buy a Galaxy SIII from the States to use here in Australia, and am having a hard time understanding the intricacies of the cellular bands. I get that CDMA stuff is a no go (Verizon, Sprint) and that it seems only TMobile and AT&T are possibilities. Here is a chart with the variants and their banding listed. http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
The variants support all 2g frequencies, but I don't understand how the 3g part works. The t-mobile one in the 3g band is
850, AWS (Band IV), 1,900, 2,100 MHz UMTS / HSPA+ / DC-HSPA+
Click to expand...
Click to collapse
, which doesn't include the 900 that some networks use here. Will the phone use only 2G if this is the case? Will that make any difference to me? Will the AT&T one work as well?
Can someone please give me some clarification? :victory:
Below is the info for Aus carriers...
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
