I have a TK103b purchased from Aliexpress as you can in the link below,
I use trackerhome (http://www.gpstrackerxy.com/) now for tracking my devices, I decided to move to GPS TRACE but I got a problem when I changed the IP address on the device, as soon as IP is change the GPRS turns off and I can not turn it on again how many times I send the command by sms!!
Is there any special to do to solve the problem?? anybody heard it before or had the same problem!??
