If you’re using an iPhone 12, there are a few ways to insert a SIM card. The most common way is to use the home button and volume up/down to select the SIM card option. If you don’t have a home button, you can use the power button and volume up/down to select the SIM card option. To insert a SIM card using one of these methods:

  1. Open the iPhone’s Settings app and navigate to General > Airplane Mode > Reset Airplane Mode. This will erase all your data and settings on your iPhone 12.
  2. Place yourSIM card into the phone’s slot and turn on airplane mode again. Your phone should now show an “Airplane Mode” icon in its status bar. To insert a SIM card, press and hold down on the icon until it turns into a small arrow (it should look like this):
  3. Drag theSIM card into place until it clicks (it should now say " inserted"). You’ll now be able to use yourSIM card!
