Blacklistef imei

You will need to return the iPad to the retailer from which you purchased the iPad - and have the iPad exchanged. You’ll not be able to lift the IMEI block yourself.

Assuming that you recently purchased the iPad from Apple, or an Apple Authorised Retailer, you should have no difficulties.

Blacklisted iPad devices are typically ones with cellular service and are blacklisted by the cellular provider.

Should be this case, contact your cellular carrier and ask them.

Neither we, just users like you, nor Apple can get involved in a blacklisted iOS device.
