At&t is requiring an imei number to register the sim card, what am i supposed to do

Ariana - Can't speak to how AT&T handles their SIM card registration ... don't have a clue. I chose to purchase a SIM card offered by PayGo Ultra Mobile (which uses Verizon's network). I placed the SIM card into a smartphone to get the SIM card registered with PayGo and a phone number established. After a phone number was assigned to the SIM card, the SiM card was instilled in the remote switch. Not positive, but I beleave I could have registered the SIM card and received a phone number by just calling the 800 number for PayGo's customer service department and providing them with the SIM card's serial number.

Will this work now that at&t has done away with 3g?

yes, it works on ATT 4G VoLTE network from May 2011, NEW stock items.
