Everything looks fine until I try to connect the tracker to the network, looks like my friends don't told me the truth about NB1 Network in Mexico.

I ask for the network status and the answer is 0,2 that means I'm not registered and is searching for the network, when I check COPS command answers that no networks availables 

looks like I designed a device that can't works in my country.

moving on... this saturday I will travel two hours heading to the south Texas, NB1 are working since last year with T-Mobile.

Meanwhile I will write the code and test de GPS module.
