To set parameters via SMS the Track Box must be turned on with the SIM card fitted. You will need to send a text message with the parameter and new value to the phone number associated with your SIM card.

When sending multiple rules via SMS then each rule should be written on a new line.

For example, send an SMS in the following format.

CUSTOMER=12345
APN=mobile.net

SMS configuration can use any of the Custom Rules which can be applied through Track Box Configuration Rules, additional useful parameters you may wish to set by SMS include: 

• APN (This can be a URL or just a string of text. You will need to look up your providers specific APN setting)
• APNUSER (APN user)
• APNPASS (APN password)
• CUSTOMER (Customer ID)
• NAME (Device Name)
• TRACKPINGURL (Server location to send data)
• STATUSURL (Server location to send status updates)
