We know LINE already allows free calling to other LINE users, but what about those who don’t have the application downloaded? Sure, you can try to get them on board, but if they decline the invite, there will soon be another option for you in the form of a new data-based calling service being offered by the popular messaging service. The service will come with two plan option: Pay-as-you-go and a 30 day plan, which LINE detailed at a company event.
