Without a SIM card the device will work on Wifi, it order to have it work on At&t 3G/Edge you need a valid SIM card, you don't need a new one, just a valid At&t SIM should do. You also must have a dataplan on your account.

After that, it really should be plug and play, if you can make phone calls, the data should work too.

Setting up Google Mail and everything else can all be done over Wifi, you only need a valid SIM to operate over the At&t network.

You should be able to also use a prepaid sim from a non-at&t carrier since it is unlocked.

You might want to validate that it is unlocked, that might be your issue.

Hope that helps. Good Luck.
