It depends on the specific Android SIM card and iPhone model you are referring to.
Both Android and iPhone devices use SIM cards in three different sizes: Standard SIM, Micro SIM, and Nano SIM. However, the size of the SIM card is not the only factor that determines whether it will work with a particular device.
If your Android SIM card is a Nano SIM and your iPhone model is compatible with Nano SIM cards, then it may work. However, you may need to contact your carrier to activate the SIM card on the iPhone network.
It’s important to note that even if the SIM card fits physically into the iPhone’s SIM card slot, it may not work due to carrier compatibility issues. In general, it’s always best to use a SIM card that is provided by your carrier or a compatible SIM card specifically designed for your iPhone model.
