New phone does not recognize SIM card

I got an upgraded phone and put my old SIM in, but it only recognizes the card about half the time. I either get an invalid SIM error message or no SIM detected at all. The door is all the way shut, there is no carrier update pending, and restarting my phone only works sometimes. Do I have to link my new phone to my account somehow, or is this a hardware issue? The new phone is an iPhone 8. Thank you!

Hey there! Are you still having issues with your SIM? @drnewcomb2 asked some pretty important questions.

It's a hardware issue. Have you tried cleaning the SIM's contacts? How old is your SIM?
