An SMS message! Who's it from?
TELCO. (They can be anonymous for now.) Apparently they think I might be travelling to Europe, and therefore that I might want to know about their new roaming rates. Fair enough - that would be some of the contextual messaging stuff the people at Acision/ex-LogicaCMG Telco Products are always talking about, no?
Well, it would if I actually was travelling to Europe. Given that TELCO knows my phone has been in the same cell, near my home address, all day, you'd think they would have thought of this - strikes me that the trainload of phones zooming along the Channel Tunnel Rail Link every 30 minutes or so must show up quite impressively in TELCO's switching centre as a lot of the same devices sending CC SETUP messages very quickly indeed.
They're probably more likely to be heavy mobile users than the general population, too. Similarly, Heathrow Airport is full of people who certainly are travelling to Europe, as well as picocells deployed in the sprawling terminals..there's surely an opportunity here to put some of the talk about advertising that "users will value" into effect, by targeting devices that have just turned up in those cells.
