How do I activate my sim card

There is nothing to activate. When you get a SIM card from your cellular carrier, that card is already active.
The reasoning is different if that SIM card is not supported on your iPhone. Should be this case, read this support article:-->How to unlock your iPhone for use with a different carrier - Apple Support
