Resetting modem...Modem is functoning properly
when I load the example "gsmscannetworks" or other shows me this:
"GSM networks scanner"
and do not go to the next step
when I load the example "pinmanagement" shows me this:
Change PIN example
PIN & PUK locked. Use PIN2/PUK2 in a mobile phone.
Note: the simcard has no pin code and works well on a mobile phone...
