All commands are case sensitive. When a user tries to send an SMS/GPRS message to TAT100, most of the time it cannot arrive because the GSM/GPRS module is disabled between sending of records. The device will receive the SMS/GPRS message when it wakes up to send a record according to the configured tracking period or scheduled time. In order to quickly execute the SMS/GPRS command and receive a response, the user should send the message immediately after receiving a tracking record. | All commands are case sensitive.
