In this piece

 //if coins value is enough to make a call - dial
  while (coinsValue >= 1)

the comment says IF so why is the next line using WHILE? I suspect it would make more sense to use IF

And there seems to be no means to get out of the WHILE loop

Are the print statements in your keypadInput() function showing normally when line 102 is called?
