I-mode is a portal service for mobile phones. There are Web -like pages shown - but adapted to the capabilities of the mobile phone displays. i- mode pages are written in chtml. i-mode (set in Germany in 2008 ) is in direct competition to WAP.
I-mode provides color text, graphics, video and sounds.

Mari Matsunaga is considered the " mother of i-mode".
