Unkown Tracking Device/missing the comand for setting USERNAME and PASSWORD

MI8 years ago

Hi all,
I got a Tracker Device from someone (Seller unknown), but documentation/manual says nothing to program GPRS USERNAME and Password.
On the Box stands "Accuratte Tracker" and the device is looking like Tracker

All manuals I had downloaded were different than the manual which came with the tracker.
Here some commands from manuals:
APN Setting--> APN,APN name Reply: APN,OK
IP setting -> SERVER,0,IP,PORT
Upload time checking-> AINFO

Does anyone know these commands and know how to set USERNAME and Password (GPRS)????????
Hope anyone can help me ! :-)

Best Regards
Michael
