On February 5, 2021, Green Echoes Studio submitted a press release to the press announcing the launch of the “Smartphone Switching Counseling Center Online” on its operating website GreenWaves.



The Smartphone Switching Counseling Center Online is a system that diagnoses the best plan by answering a charted questionnaire.

After diagnosis, we also provide information on how to transfer by clicking on a separate page link.


Please see the press release for details.

Although cell phone rates have dropped, there is still a high hurdle for ordinary users to switch without changing their numbers.

GreenWaves will continue to communicate about saving money on communication costs.
