Maybe your SIM card is full. SIM's aren't used to store contacts anymore.

Welcome to Android Central! Which phone? I strongly recommend saving your contacts to your Google account instead, since they will sync automatically with your Google Contacts in the cloud. That way, if something happens to the phone, you won't have lost all of that information.
