Important information for World Cellular Information Service users

Informa Telecoms & Media (ITM) has recently merged with Ovum

As a result, if you are a former ITM customer you will need to reset your password here to gain access to World Cellular Information Service (WCIS) via the new Ovum Knowledge Center or via www.wcisplus.com

WCIS is available as a Data Tool on the new Knowledge Center.

Please contact your account manager or mail enquiries@ovum.com with any issues.
