New sim card, data not working [UPDATE: disregard]

[CamiKitti]

I got a new microsim card for my Nokia Lumia 920 from H20 Wireless and now, the data won't work. I used to be with AT&T, and I have no idea how to reset the network settings (or is that just an iPhone thing?). Please help. What do I put in the internet or mms apn? I don't know how to configure this thing to make it work. Do I have to unlock my phone for this to work?
