See the troubleshooting here, If you see No Service or Searching on your iPhone or iPad - Apple Support
However, if you are seeing SIM not supported, that means the iPhone is locked to a carrier other than the one you are trying to use the SIM for. See this for that error. How to unlock your iPhone for use with a different carrier - Apple Support
