The phone appears to be compatible with all bandwidths up to the 4G network. If your sim is up to date with your network coverage, it should all work. Check this product review to determine if this info is correct and maybe check with your service provider that the networks are compatible so you don't end up with a phone that is a paperweight.

Try using sim from some other network. Maybe the device does'nt support Verizon bands. Also, At&t is GSM and Verizon is CDMA. Different systems. Try using a GSM sim.

ATT and Verizon use different radio technology. Many phones/tablets have both radios but not all. It is likely that the hardware will never work on VZW

PUK lock (Personal Unlocking Key). It's a security feature on most mobile devices that protects your SIM card data and unique for SIM card.
May I suggest that you contact your sim network provider as they are the only one who can provide you the PUK codes. Once you done the PUK unlocking you can use the unlock code.
