Mobilereg Nigeria Ltd operates Fonreg, an online platform that aims to reduce mobile phone theft and crimes by allowing users to register their phones and check IMEI numbers. Fonreg's services include allowing individual users, police, and mobile operators to register phones, check if a phone is lost or stolen, and access a database of registered phones. Fonreg also integrates with other services to check IMEI numbers and notifies owners if a phone is reported as stolen. The goal is to monetize these services through commissions, advertising, premium SMS checking, and revenue sharing with mobile operators.
