However, Vertu makes a point by saying the Ti is different from others, as it offers the titanium and sapphire crystal, and a live personal assistant on-call at the press of just a single button. The button is at the left side of the device ad when pressed, this button opens a dedicated menu where a call can be placed to Vertu's trademark personal assistant. Vertu's Concierge Services outsource a lot of the functions – such as booking exclusive hotels and dinner reservations – that many of us do through apps.
