As seems to be the case in many airports these days, there is Wi-Fi coverage all over the lounge area in Terminal 3 at London’s Heathrow, but you’d better make sure you have a full charge on your batteries if you plan to use it as even at the dedicated BT and T-Mobile hotspot ‘zones’ the power sockets have no juice.

And forget finding sockets anywhere in the main waiting areas – there’s none to be found (they’re all hidden under special covers in the floor). I have to wonder what the point of providing the Wi-Fi is if they don’t also provide the power for the laptops.

Still, it did work well for a quick connection from my N95 earlier – I connected to the BT Openzone, fired up Truphone and made some free international calls to let people know I’d arrived safely!
