Before you can use your newly purchase iPhone 5, you will need to insert the SIM card into it. Unlike its predecessor which uses the Micro SIM, the new iPhone 5 uses a nano SIM card, a smallest version of the SIM available today.
Tools Require: SIM eject tool, or a small paper clip.
1. Hold the iPhone carefully and insert a SIM eject tool into the hole at the SIM card tray, to allow the tray to pop out.
2. Now take out the tray and carefully place the Nano SIM onto the tray. Make sure the Gold surface is facing down.
3. Then gently put the SIM tray back in.
4. Switch on your phone and start the setup process.
