K-Messages is the united messaging platform for Kal-OS. On either a computer or handheld, this will be the K-Messages app. The user will send a message to either their NIN, or cellular telephone number. When using the K-Messages platform, then either will work. However, if the other end has a cellular phone, and no NIN, then that can work as well. With exception of SMS messages, all messages under communications will be data. In order for a computer to send SMS messages, it must be paired with a cellular phone that has active service. The following colors are as applied:
- Kal-Messages: Blue
- RCS: Red
