I'm moving from Android to iOS -how do I move my sim card from the android to the iPhone 8. And the iPhone 8 will not take any memory card correct?
Eject the SIM card from the current phone, and insert it into the SIM slot on the new phone.
… Remove or switch the SIM card in your iPhone - Apple Support
If you are moving to an eSIM-only iPhone, contact your carrier to relocate your cellular plan.
An iPhone 8 has a SIM slot, so that eSIM switch won’t be necessary for your particular case.
iPhone does not provide an internal memory card, but can use a Lightning or USB-C flash drive to transfer files, with the connection depending on model. iPhone 8 has Lightning.
