I removed the SIM card tray but no SIM card came out?

Hi there LindsaysFamily,

We understand you're trying to remove the SIM card from your iPhone 8 Plus, and we'd like to see if we can assist.

If you removed the SIM tray and there wasn't a SIM card in it, look into the empty slot and check if you see it in there. This page has additional information: Remove or switch the SIM card in your iPhone or iPad

Specifically, the information below may help:

"To pop open the SIM tray, insert a paper clip or a SIM-eject tool into the hole beside the tray. Push in, towards the iPhone, but don’t force it. If you're having difficulty ejecting the SIM tray, take your device to your carrier or an Apple Store for help."

Regards.
