How to Fault Find SIM Cards
1) Make sure the SIM card is facing upwards and the card cutout side face is towards the left. You can also use the external SIM card holder that plugs into the A port for easy access
2) After inserting the SIM card, the device MUST be restarted in order to read the Sim card. Swipe the screen task bar down and select "Reboot"
3) If SIM card has PIN code, the SIM card will NOT work. Please remove PIN code from sim card before trying to make SIM card work. Sometimes your network operator will have to be contacted to remove PIN
4) If all steps above fail, check with a different SIM card you know works and has no PIN code and repeat steps 1 & 2.
5) Verify your APN settings are correct according to your provider (must be set to android tablet APN settings)

- NOTE: Some times the parameters for the SIM need to be reset if no data is working. It is best to reset all the mobile network settings and set up a new APN from scratch.
6) Some SIM cards are thinner than regular SIM cards - If you insert your sim card and it is not registering as being inserted on the head unit, you may have to place tape on the backside of the SIM card so it can make better contact.
7) Don't use Sprint and Verizon sim cards. T-Mobile pre-paid works and AT&T is ok
8) The unit is intended for use with data SIM cards and not for making GSM phone calls. Some clients reported to be able to receive calls with google phone for example but cannot make calls. For this reason we do not recommend using SIM for calling.
