European GSM

Okay, stupid newbie question:
What GSM Network does Europe use? Or, specifically, Ireland? I.e. 1800/1900/etc??
Thanks in advance.

All of Europe uses GSM 900/1800. Some providers use GSM 900 or GSM 1800 only (like Meteor in Ireland) or a combination of GSM 900/1800.
You can check here to see which provider uses what band in which European country:

What other carriers (anywhere not just USA) use AT&T 3G/4G Frequencies?

What other carriers (anywhere not just USA) use AT&T 3G/4G data Frequencies? Basically where else in the world could one get 3G/4G data with an AT&T phone.

most of Canada,some in austraia and new zeland and some in south America. not sure about aisa. but I can tell you bell telus and rogers from Canada are all compatible. can't really name the ones in other countries but maybe someone else can help out.

Works for me here in Mexico, just had to add the proper APN for my carrier Telcel and its good to go, i think some central and south america countries too i had a friend from Argentina telling me he bought and Infuse also and its working good on his carrier Claro.

Works in India on a few networks. I was on two - Airtel and Tata, and it worked on both. Airtel used 900 GSM and Tata used 1900 GSM for 3G.

Thanks to everyone who has helped!

infuse use 850/1900/2100
and AT&T use 850/1900
and 2100 is used all over the world.
I don't know why american carrier use other frequencies
but except United States, all use 2100 for 3G
so, if you unlock your infuse, you can use it everywhere

Looks like you are referring to EU markets.
I was in India a couple months back, and my Infuse was on 1900 band on Tata network for 3G.

[Q] TF101G - 3G Network bands?

I want to buy a tablet in USA market, i like Asus Transformer, but I need support for 3G Networks on North & South America.
Can't find official info about the supported frequency bands
TF101G supports UMTS 850/1900 ? (required for South America)
Thanks!

It's Quad band

Thank you baseballfanz, you're right.
My confusion comes because Asus don't put frequencies in the specs:
Mobile broadband: GSM Quad bands, HSPA+ (I,II,V,VIII)
So, just for aclaration:
Band I (W-CDMA 2100)
Band II (W-CDMA 1900)
Band V (W-CDMA 850)
Band VIII (W-CDMA 900)

[Q] 3G not working in Thailand ?

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.

[Q] Could someone please explain Cellular bands that I can use in Australia?

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...

, 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
