Bring also a pin / needle or a tool for removing the SIM card from the iPhone. This is just in case anyone know the seller does not carry / have these tools.
Supplement: Flashlight, data cable, and headphones. Maybe also a laptop.

Plug headphones into the iPhone and hear a song. Make sure that the sound can still be heard clearly through headphones. If you have time, another person's phone and heard the voice of the headphones.

If you could bring a laptop, try to connect the iPhone with a data cable. This is to check if the connector of your iPhone or data cable is normal or not.

Test the functionality of the iPhone

You could say this is the version check of the existing deep above. Because it may be, you need to test your iPhone more carefully.

Buttons and switches

Through the Home screen, open any application, then press the Home button to return to the Home screen.
Press the volume up / down the iPhone and noticed indicators that appear on the screen, make sure that when you press the volume indicator is also changed.
Turn the switch ring / silent and watch the bell indicator on the screen. At the time converted to silent mode, the iPhone is supposed to vibrate.
Press the Power button on the top side of the iPhone to turn off the screen (instead of turning off the iPhone, but sleep). Press again to turn on the screen.

GPS

iPhone uses signals from GPS, hotspots (Wi-Fi) and BTS for location accuracy. If GPS is available, then the location indicator on the map application will be a blue ball. GPS testing should be right under the sky that could be easily detected by the satellite.

Go to Settings> Wi-Fi and connect to a Wi-Fi network is available in your location.
Open the Maps app, and tap on the icon or the arrow keys on the left-side of the screen. Maps show where you are right now.

Special case

Some people sell his iPhone for a few things. One is because it is in a state iPhonen locked (SIM locked or locked iCloud), and can not be used to call for not being able to run a SIM card other than the operator of origin. iPhone is in this condition usually sold its owner because of despair, because the cost to unlock IMEI too expensive. Usually the owner will sell it at a cheaper price.

My advice, do not buy the iPhone is locked. Unless you have other considerations, or have enough money to buy IMEI unlock services.
