Korea’s third-largest mobile carrier LG U+ said the company’s operating profit in the second quarter increased by 59.2 percent on-year, the fastest growth rate for three consecutive quarters among local mobile carriers.

In the meantime, quarterly sales for LG U+ went up by 5.1 percent on-year to reach 3.2 trillion won ($2.7 billion) during the April-June period, the company added.

Since the fourth quarter last year, quarterly operating profit for LG U+ has increased by 75 percent, 11.5 percent and 59.2 percent on-year, respectively.

Of total subscribers, the company’s 5G subscribers accounted for 11.3 percent in the first quarter this year, compared to 2.6 percent from a year earlier.
