Too easy!!! Adafruit SIM5320E dials and connects a voice call.

Shervin and I plugged the battery, antennas and earphones into the board. Connected the USB cable to a window7 machine. Installed the drivers from the Adafruit site. Connected through serial using putty.exe and Shabang!! It dialed a voice call successfully using the earplugs. The call was as clear as crystal… We didn’t expect it to be that easy. Wow!
