We check device IMEI numbers live against a variety of independent datasets, including the GSMA Global Blacklist Registry, to provide the most up-to-date information possible on the history of a mobile phone, including whether or not it is network blocked, has been reported lost or stolen, is under finance, or has been subject to an insurance claim.. Protect yourself before you buy, providing security and peace-of-mind that your purchasing decisions are free from mobile device fraud.
