Internet giant Line Corp. on Monday made its foray into mobile phone services, launching low-cost smartphone and SIM card packages that offer subscribers free use of its messaging app.

Branded Line Mobile, the service, excluding the cost of handsets, will cost between ¥500 and ¥3,220 a month, depending on data usage, the new company said.

And in a win for Line users, the firm said Line Mobile subscribers will have unlimited data usage for some Line services, including the sending of text messages, photos and videos, as well as Line voice calls. It also said plans are afoot to exclude data used for Facebook and Twitter as well.
