 Cellcom, Israels largest mobile phone operator, reported a wider quarterly net loss, weighed down by an expense for a voluntary retirement plan, and warned the coronavirus outbreak would harm future earnings. Cellcom said on Monday it lost 54 million shekels 15 million in the fourth quarter, versus a 35 million shekel loss a year earlier. It recorded an expense of 45 million shekels for the retirement plan of 450 workers and said it expected to gradually see cost savings from the second quarter.
