To upgrade your iPhone 4 to iOS 5 without SIM card activation, you can use iTunes on your computer. First, ensure you have the latest version of iTunes installed. Connect your iPhone to your computer, put the device in recovery mode by holding the Home and Power buttons until the recovery mode screen appears, then click "Restore" in iTunes while holding the Option key (Mac) or Shift key (Windows) to select the iOS 5 firmware file you downloaded. This process will install iOS 5 without requiring SIM card activation.
