Iphone 4S Unlocked Can't Use 3G Data Network

[reefsurfah]

I brought an iphone 4s from ATT that I got unlocked in USA by a third party. I'm able to connect to the 3G network, however, I can't send/receive data even after using an APN changer (unlockit.co.nz) and/or setting the APN (I needed to do a sim swap to get to that menu). I've tried a different sim from TRUE move, I went to one of their branch offices and it still didn't work. Any advice here?

I hope we get some insight a I was about to have the same thing done to my at&t 4s before my next trip over. My wife I there now and using one of our old 3gs's. I'll ask her if she is getting 3G data in it and get back to here about that at least.

Yeah, I've read that there were some issues with the 4s in thailand on apple forums. I am wondering if anyone has it working, perhaps even using other carriers like DTAC or AIS.

I guess it's just the fours then yes? Wify said 3GS no problem on 3G network in Bangkok so there ya have it. Hope we hear of a solution or resolution about the 4's soon as I'm goin to hold off on the unlock till then I think and just take our other 3GS with me instead.

You have tried "Reset Network Settings" right?

Settings -> General -> Reset -> Reset Network Settings

For normal iPhones, that fixes 3G issues most of the time.

Yup, that worked, thanks for the advice.
