Cellicium, a wholly owned subsidiary of Switzerland-based Esmertec, says it has successfully implemented its Unstructured Supplementary Service Data (USSD) Browsing solution for Senegalese mobile operator Sonatel Mobiles (Alizé). The new service, which is being marketed under the ‘Magik portal’ banner, has attracted over seven million sessions from Sonatel Mobiles’ one million-strong subscriber base, in the month since it was launched. Sonatel Mobiles’ Products and Services Manager Laurent-Marie Kiba said: ‘This has significantly increased user traffic of our value added services (VAS) and created strong mobile user stickiness, distinguishing Sonatel Mobiles from its competitors.’ Customers dial a simple access code to access Magic Portal in return for services such as email access over USSD, news, infotainment, logo and ringtone downloads, etc. Pre-paid and contract users can browse the menu for free and are only charged for the VAS they download and use.
