You need to define the APN. It's strange your att SIM wasn't automatically recognized and the apn settings loaded. I have a 7 year old att SIM and when I put it in my Mega it automatically loaded the wap.cingular APN settings and I had to take no action on my part to enable 3G data.
I am on media net so your data plan maybe different than mine and that could be the difference on why the mega didn't auto define your APN settings.
Here's what I'm pulling down on media net HSPA.
