A tablet works fine without a SIM, as a SIM is for service (data, phone, etc.) and not for making a tablet just work.

However, if the SIM is not working correctly, then the only people who can help with that is the carrier/service provider you got the SIM from. I would contact them about getting your a working SIM.
