When running this example make sure you have:
- edited the SIM PIN, APN, USER and PASSWORD for you network operator
- have inserted a SIM card with enough credits
- the antennas connected
- have good reception (especially for GPS)
- installed the mbed CDC drivers if you run windows
- connected a terminal program, such as teraterm
The example will connect the modem to the network and attach it. I will place a post request to download a file from mbed website. It will do a USSD request and finally wait for incoming SMS. It will try to answer your SMS (try asking "where are you").
You should see a similar output in your preferred console program:
