IOCL-PhoneBook mobile application has been developed in-house by COIS for all IndianOil employees – those on rolls as well as those superannuated, and provides Contact details of all IOCL employees on their mobile phones. The application is near replica of the hard-bound directory booklet albeit with a lot of value added features. It has a very light footprint. Some of its important features are as follows: Employee search based on employee number and name. Employee search based on division, location, department and grade combination. Search and Download of IndianOil directories. Ex-employee search based on year of retirement, PRMS payment unit and grade. Nominated hospital search based on city. Sharing of employee contact details through WhatsApp, Messenger software or Email. Ex-employee access using the PRMS login credentials. Offline access to downloaded directories and list of nominated hospitals.
