If it shows "Not enabled" on the APP, we need to set APN first.
Firstly, Need to ask the carrier about the APN informtaion of the SIM card in tracker.( APN name, APN username and APN password)
Then send those command:
- gprs123456
- apn123456 "APN name"
- apnuser123456 "APN username" (no need to set if without apnuser)
- apnpasswd123456 "password" (no need to set if without password)
Have a space after 123456 , don’t need to send last two commands if sim card don’t have username and password.
For example For Speedtalk
APN name: mobilenet
APN username: (none)
APN password: (none)
Then send 2 commands:
- gprs123456
- apn123456 mobilenet
If u do not know how to set APN, you can leave email on Amazon, we can set apn for you, its the easiest way.
