Hi vinodrai,
You will need to go into Settings - Wireless and Network - Mobile Networks - APN
The settings that should work are as follows:
Name - PTA
APN - pta
Proxy - Leave Blank
Port - Leave Blank
Username - Leave Blank
Password - Leave Blank
Server - Leave Blank
MMSC - http://mmsc.mobile.att.net
MMS Proxy - proxy.mobile.att.net
MMS Port - 80
MCC - 310
MNC - 410
Authentication Type - Leave Blank
APN type - default,mms,supl,hipri
Bearer - Leave Blank
If there is any settings that are not listed here leave them as default. You will need to hit the menu key and then save after inputing all the information. Otherwise you'll have to retype everything. You may need to restart the phone once you put the APN in.
Also I just saw you said it was an unlocked S3? There is a possibilty that it is the international edition that won't support LTE bands. Is it a branded AT&T S3?
Hope this helps!

I have an international S3 that my company didn't want anymore, and I am trying to get decent data speeds with it on my personal account. Do you know the optimal settings for the international version? I think it specified Cingular in some of the settings, but the girl at the local AT&T shop messed around with it and now it is just plain slow. It even makes my speakers buzz like my old Blackberry did...

Is it an i747 or i747M?
I had a similar issue with an unlocked S3 that I bought. It was advertised as an i747, but it was actually the Canadian version, i747M.
I used the same apn settings as above, (not the Cingular settings)but finally had to send it back because I could not get any speed, and the data connectivity was unreliable. Kept dropping the connection even though it still said 4g connected.
It would also drop network connection when I made or received a phone call.
You can also use the same settings as above, but in APN, put PTA. APN name can be anyting you want. (Got that from AT&T TS to try to resolve the 4G issue)
According to Samsung tech support, it was because of the firmware and modem being Canadian.
According to AT&T TS, it should still work.
You can flash the ROMs built for the i747, but for the modem you can only use the I747M.
I spent hours on the phone with Samsung TS, and a while with AT&T TS, and was never able to get it working properly.
It was either a defective unit, or the International/Canadian version firmware was the issue as Samsung had said.
I just sent it back for a refund and am ordering a true US version.

Disregard my part about the APN, I missed that the previous posts already had PTA as the APN.

I am not sure if it is a 747 or 747m - is there an easy way to tell? I didn't see anything obvious in the settings, or on the label under the battery...
