Help International S2 - unable to get 3G internet from AT&T

[buttoxide]

Hey all, I have this problem which I think not many will have.

I have an international Galaxy S2. As I'm a foreign student, I brought it to the US and am now using AT&T as my service provider. In the past, my international blackberry was easily able to use the 3G internet provided by AT&T. However, for some reason, I am completely unable to use the internet on this phone.

Calling and texting is completely fine. However, Internet simply does not work outside of Wi-Fi.

I have done the following:

• Use Packet Data is checked
• Rooted my phone (it didn't work before and after the rooting)
• Kernel version is KL3
• I have "Quick Settings" app and it shows "connecting" under Mobile Data
• GPS receiver works fine (Google Maps works just fine in locating me)

I've tried googling for help but I can't really seem to find a solution for this. I've called AT&T and followed their instructions (mostly turning off / unplugging the battery). The Access Point Names has ATT WAP (wap.cingular) inside as well and highlighted, but still no dice.

According to http://androidforums.com/hero-support-troubleshooting/45005-mobile-network-apn-settings.html AT&T's settings should be the following:

Name: AT&T
APN: wap.cingular
Proxy: leave blank
Port: leave blank
Username:WAP@CINGULARGPRS.COM
Password:CINGULAR1
Server: leave blank
MMSC: http://mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS Port: 80
MCC:310
MNC:410
APN Type: leave blank

The only difference between mine and the above is that my Username and Password for the APN is <Not Set>.

Any help would be appreciated. Thanks!

The International SII is quad band, but it sounds like AT&T's internet band is at a frequency the phone doesn't cover.

Try editing the APN and adding the username and password?

The international version supports the 800 and 1900MHz bands used by AT&T.

Thanks so much for your input! I finally got it working. Here's what I did:

I didn't know there was a way to key in a new APN, so I did that and keyed it in.

Also, in the quick settings app, holding the Mobile Data key brings up a checkbox to Quick Settings > Preferences which had the one option "Switch 3G directly". I checked the box and now everything is working fine.

Cheers

Where is this?

Don't see anything like that in the settings either. Its just having data on or off. I have a toggle to do that instead of going all the way into the settings. Also, using widgetsoid and it can set up a toggle for switching between 2G and 3G if you want.
