Because the new sim is probably not programmed or not programmed to the carrier you are using and the phone is locked to a carrier. You can only use a sim for a different carrier on an unlocked phone. If you are replacing a Sim for the same carrier - it has to be programmed before you can use it. The sim contains all your carrier and account info - not the phone. The phone can be locked to only accept programmed sims from the carrier that sold you the phone.

Try with another sim card, clean the sim connector of your phone, reset you phone to Factory Setting (default) using 12345. If you can open it, clean the mobile thoroughly using IPA solution. This problem is caused by Firmware problem and Hardware problem as well. Good luck.
