I was now able to make it work like I wanted.
The only problem is each time I unplug the device from the wall and plug it back , I have to
do the AT function again , as it does not save it internatlly , How can I input it at startup ?
The function is : AT+COPS=1,0,Rogers Wireless,7
what happen is that , when I restart it , the COPS become 0,0,Rogers Wireless, 7
I really need to keep the 1 active as I want to ensure the system will not look for other carrier.
thanks
