//If you are using apache dependency version 3.12 then you need to handle different way. The switch case statement should be replaced in the following way for numeric cell types.

switch (mobileCell.getCellType()) {
case NUMERIC:
	info.setMobile(NumberToTextConverter.toText(mobileCell.getNumericCellValue()));
	break;
case BLANK:
	break;
default:
	break;
