Insert SIM card

With your fingernails of your thumb and index finger gently pull out the SIM card tray.

Place your nano SIM card into the SIM card tray 1 with gold contracts facing down.

If you use two SIM cards, place your secondary nano SIM card into the SIM card tray 2.

NOTE: T3 is only compatible with nano SIM cards. Any other incompatible or modified SIM cards can damage the SIM card, its data and the phone itself. Any such damage is not covered by the warranty.

To insert the SIM card tray back into the phone make sure the tray is positioned correctly, then carefully push it all the way in. Make sure the tray is inserted properly.
