AT&T 3G i9300 in USA? - Galaxy S III Q&A, Help & Troubleshooting

Ok, so I had to sell my i9305 because of lack of any data connection above 2G/Edge on AT&T for my area due to frequencies that they use here.
How many people in the USA are using an unlocked international i9300 on AT&T and getting 3G+ data??

Nobody in the US has an i9300?

It works and you get hspa+

I'm on AT&T as well with the i9300 that I won from Engadget.com and it works just fine. H+ all the way for me as well.

Thanks guys, I appreciate the responses. I spent 700 beans on an i9305 to find out it didnt work. Just wanted to see if the i9300 worked. One more question, Do you guys have the LTE versions or the non-LTE?

Firstly, GT-I9300 supports 1900MHz for sure but 1900MHz WCDMA support on GT-I9305 is based on different region. For example your GT-I9305 has no 1900MHz 3G but the GT-I9305 sold in Hong Kong supports 1900MHz WCDMA.
Secondly, it is quite meaningless to buy LTE phone outside and use it in the US because only Bell and Rogers Wireless support LTE 2600MHz, you will not be able to use LTE network on AT&T.
You may use the any Korean LTE version(SHV-E210S/SHV-E210K/SHV-E210L) because the all supports 1900MHz WCDMA. Or otherwise, you may use the AT&T model of Galaxy S3.
I am using SHV-E210S, there is no SIM lock on the phone.

Thanks for the info, though I had an i9305 Hong Kong version and it did Not get 3G or 1900MHz, I could not even select it. I was hoping the 9300 would be different.

Configuring different carriers

Hi,
I currently have an HTC Desire running on Puerto Rico's Open Mobile CDMA EvDo Rev. A network. It seems to me that the Galaxy S2 does support this network, and I had the Vibrant before and loved it, so I'm thinking about selling my phone for an S2.
Now, I've been searching info on how to configure / change carriers on the S2, as the phone is not available on mine. Haven't found that yet.
Anyone have a link / tutorial I can use?
Thanks!
The international sgs2 does not support CDMA, the sprint (USA) version of the sgs2 supports CDMA but you would have to check what bands your local carrier uses compared to sprint, and if you can activate an American phone on the network even if the bands match.

[Q] German SGSII

Simple question,
Does the German version SGSII, MPN GT-I9100LKAXEU work on ATT 850/2100 HSDPA network? Or for that matter all bands on HSDPA.
Thanks

Att hspa network is 850\1900, so if it has this bands then it will work.

Can anyone tell me for certain that this phone has the 850 band for HSDPA?
I cant find any definite tech specs that specify.

4g on international S3?

Hi, I am debating on buying the international galaxy s3 or T-mobile's galaxy s3 (the dual-core model). Since I am from the US, would I be able to use T-mobile's 4g if i bought the international version?
No. Hardware differences.
This has been asked countless times before.

If you live in some parts of California or the east coast that have 1900mhz 3G it will work. But that only covers like ten cities max. It would be 2G everywhere else.
Also T-Mobile doesn't have 4G.

Hey!
No its not international I'm leaving in UAE and I'm using Du cariouer and its not supporting 4g so it depends on the operator

Gt-I9300 international on U.S. T-mobile

Just curious, I have the international and I am on T-mobile in the U.S.
Will the I international ever be able to attain 4G Speeds on T-mobiles network? For instance once quad cores become the norm in phones (like they are on the verge of doing).
Or would I be better off selling and getting a T-mobile g3?
Thanks in advance.

Ok. 3g would be great. For the most part that is what is in most areas anyway. I just wasn't sure if it was our phone that didn't have the right radios or if it was T-mobile/other carriers that didn't have the right modems for our exynos.

International S3 does not have 4G chip in it
The max network speed that could be available with an international S3 is 21Mbps HSPA+

And is this based off of what's available now or what will be available in a year?

[Q] WCDMA frequency not working on SGS2 i9100

Hi guys, I'm from Canada and I recently bought a new Samsung Galaxy s2 GT-I9100XXKG1 from Hong Kong on ebay. I'm running it on the Rogers network here in Manitoba and its been working fine on GSM, (although the it frequently drops signal when service isn't 100% ) but as soon as I switch it to WCDMA only it won't pick up any signal at all!.. I have set it for Automatic in Service Mode but nothing seems to have changed.. please help!? (I have not rooted this phone yet)
That's a problem of the network. May be rogers don't have 3g bands of I9100

The Rogers 3g network uses the 850/1900 band. I upgraded from a Samsung Galaxy Q and I had the best service anywhere with 3g.. Does the i9100 not support these frequencies?
