ReachFar V43 Cat-1

Before you can use the gps tracker Reachfar you need to authorize your cell phone number of your smartphone / cell phone.

Authorization means to allow just only that number to send instruction commands to the gps tracker and to disallow requesting a location by call or sms from other numbers. This is a kind of security feature.

Don't use the number in the tracker for authorization, use the number of your cell phone (!). This authorized number is also called admin number, master number or center number. Please use the international number format (41,43,49, etc.) without leading +.  

Doesn't reset with factory reset.

If the APN needs user’s name and password, for example: the user’s name is “cm”, password is “123”,
then the SMS command is “apn,apndate,cm,123,,#”

Please set main monitoring number first by sending below command from your own phone to
the tracker SIM number: pw,123456,center,your own phone number#
