Identify your iPhone or iPad model.
Damage to the SIM tray or the device caused by a modified SIM card isn't covered by Apple's hardware warranty. If you cut or modify your SIM card to fit a different device model, you might not be able to connect to cellular networks or access certain features using that device.
If you get a new iPhone and your old SIM card won't fit, contact your carrier to move your account to the SIM card that came with your iPhone. Or ask how to get a new SIM card if your iPhone didn't come with one.
