▪  First of all check that your device is supported by Smarterping in the list of supported devices;

▪  Check that your SIM has sufficient credit/balance and that the SIM is enabled and activated for GPRS.

   Test this by putting the SIM into a cell phone and browse some web sites over GPRS. (Note that some

   operators require you to call them to activate the SIM for GPRS);

▪  Make sure that the PIN code on the SIM is inactivated;

▪  Check in object list that the device IMEI is correct;

▪  Check that you are using the correct APN. Ask your operator what APN to use with your SIM. Operators

   sometimes change an APN;

▪  Check if there is a username/password needed for the APN;

▪  Wait for the device to get a satellite fix, this can take some time (and is best achieved outdoors with clear

   sky);

▪  Check that the device has a network connection (GPRS status is indicated on most GPS devices).
