Remove Your SIM Card From Your iPhone
It doesn’t matter if you use a physical or digital SIM; you need to make sure you remove it from your iPhone before you get rid of it.
You don’t want to lose your SIM or keep it linked so other people can use it if they get a hold of your iPhone.
To remove a physical SIM, you’ll need to remove the SIM tray that should be on the left side of your iPhone.
If you use an eSIM, you need to do the following:
- Open the Settings app.
- Tap on Cellular.
- Scroll down and select Delete eSIM.
- Tap on Delete eSIM to confirm your decision.
Note that you’ll also be prompted to remove your eSIM when doing a full erase on your iPhone, so you can skip this step if you’re planning to wipe your old iPhone completely anyway.
