Mobi is a Java-based mobile application, which allows users to interact with the Esoko application through an easy set of menus on their mobile phone.

Mobi has been tested to function accurately on the Nokia, Sony Ericsson and Samsung brands of Java-enabled phones.

A provisional list of models on which Mobi works well includes:

Nokia 2330 C, 2355, 2505, 2600, 2610, 2730 and models above;

Sony Ericsson C510, C702, C901 and models above;

Samsung SGH-P310 and SGH-E250i.

Mobi may function on other phones as well but its full compatibility cannot be assured.
