iPhone saying sim not supported.

I recently collected an iPhone from my sister making it a second phone and I tried to put my sim into it but it’s saying sim not supported. What do I do?

The phone is locked to a different carrier than the carrier of the SIM you're trying to use. Either use the same carrier your sister was, or contact the carrier the phone is locked to and ask them to unlock it.
