Looking at the back does your unit have a black top section? If not, yours is a WiFi only model.

If on the other hand you have a cellular model you should see a tiny slot with a hole for the SIM tool to fit to unlatch the cover to get to the SIM on the left side just below the headphone jack. If you don't you don't have a GSM model that uses a SIM (you have a CDMA model).
