My tab don't read the sim

The SIM may not work in that device.

You will have to contact the company (carrier/service provider) that you have the SIM through and check with them to see if it will work with your tablet. If they say yes, then you may need to have them send you a new SIM. The one you have may not be the correct one for the device.
