Installing SIM card in iPhone 4 is the first step to fully experience the wonderful world of iPhone. Installing iPhone 4 is slightly different as compared to previous iPhone 3GS – it’s located on the right side of the iPhone instead of at the top in 3GS and one more thing that make it differs from its predecessor is it uses a micro SIM (15 mm x 12 mm) instead of the conventional size of mini SIM.
1. Check out the right side of iPhone 4 device. Insert SIM eject tool or use the end of paper clip into the small hole on the SIM card tray.
2. Push the paper clip until the micro SIM tray pops out. (Personally I have to push a little harder as compared to 3gs)
3. Pull out SIM tray and place SIM card in it. Make sure the gold plated circuit faces downwards. Then carefully insert the tray back into its place.
