* NO CALLING ACCOUNT / NO SIM CARD

You can talk as long as you have a terminal that can connect to the Internet.
You don't need a calling account or SIM card on your device.

You can make a call using a tablet or smartphone that is just connected to Wifi.

* FREE SAVE UP TO 10GB PER EVERY COMMUNITY

File storage capacity is calculated by the number of members who belong to the community.

* STAR TYPE COMMUNICATION ENABLED

Even if you join the community to share information in your apartment or school, you don't want to exchange contacts with people you don't know, right?

By using commin, you can operate a star type community.

When used as a contact network at school, teachers and parents can contact each other, but parents can create a community with no connections.

If you use it as a contact network for sharing information in the condominium, you can contact the management company and each room, but you can create a community where the people in each room are not connected.


Of course, it's easy to create a community that everyone can contact each other immediately, such as between family and friends.


Let's create various communities and fun communication life.
