I cannot get the SIM card tray to eject .
Why can't I get the SIM card tray to eject (or open) so I can switch SIM cards between phones? I even used a paper clip and that special SIM card eject tool.
iPhone 6s Plus, iOS 15
See the following Apple Support article for information on ejecting the SIM card: Remove or switch the SIM card in your iPhone - Apple Support including the following excerpt:
Push in, towards your 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.
