If you are able to make calls the Sim card works fine and you are registered with your carrier.

If you are not able to make calls:

• Try a different Sim card for the same carrier (You can obtain a Sim card from a friends, family member, or co worker, or check with your local carrier store).

• Contact your carrier to ensure your plan is still active.

If your phone is unlocked, and you are using it on a different carrier, you may need to get your new carriers APN settings.
