In order to ensure all users' accessibility to the internet, each telecom carrier implements their fair usage policy to monitor data consumption. If a user's data consumption negatively affects other users' internet connections, the telecom carrier may enforce speed restrictions temporarily. Please note that under such circumstances, KKday has no right to intervene.
The quality of communication may be affected by outside conditions; surrounding landforms (e.g. mountains), weather, obstruction by buildings, the number of users, or locations may affect the speed and quality of the internet.
