  This example prints out the IMEI number of the modem,
- then checks to see if it's connected to a carrier. If so, 
+ 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.
