Fans will be able to download footage of the tour, starting on 9 June in Dublin. Williams signed an 18-month 'brand ambassador' deal last July.
Pleon will host VIP parties and raise awareness of T-Mobile's partnership, including promotion of the new Robbie Williams Sony Ericsson phone.
Pleon consumer director Eva Keogan said: 'There will be special content available and a host of Robbie products.' Pleon will work alongside T-Mobile's retained corporate, B2B and consumer PR agency Brands2Life.
