- GSM Scan Networks
-
- This example prints out the IMEI number of the modem,
- then checks to see if it's connected to a carrier. If so,
- it prints the phone number associated with the card.
- Then it scans for nearby networks and prints out their signal strengths.
-
- Circuit:
- * GSM shield
- * SIM card
-
- Created 8 Mar 2012
- by Tom Igoe, implemented by Javier Carazo
- Modified 4 Feb 2013
