Yesterday I received the following text message from O2: “You’ve gone over your data allowance on your mobile. You need to cut down or get a bigger Bolt On to keep using the internet.” I thought this was strange as I’ve an unlimited data bolt on applied to my O2 UK contract so I decided to telephone O2 customer services to find out a little bit more. Here’s what happened.

A new study from ABI Research says about 16% of mobile data is diverted away from conventional mobile networks today – and that figure is expected to treble to 48% by 2015. However, the overall amount of data traffic will have grown by a factor of 30 by then, which means that 'offloaded' data will expand 100-fold.

The second quarter of this year was the best quarter ever for connections via the O2 UK 'partner channel', according to a statement from the company today. Blackberry connections through partners also reached a new quarterly high, as did connections via O2 Centre of Excellence partners and both of O2's strategic partners (Avenir and Azzurri).

Vodafone UK has launched the Vodafone Mobile Wi-Fi, a WiFi-enabled mobile broadband device that allows up to five people to simultaneously connect to the internet over the Vodafone network. Similar devices are already available from Three UK and The Carphone Warehouse.

Supermarkets. You either love ‘em or hate ‘em. Actually, that’s not true. Most of us seem to be happy enough with a half-price bottle of wine but less convinced about globalisation and supplier relationships.

But none of that’s bothering me today. Instead, I’m troubled – as I have been for several months – by the TV commercial for Tesco’s prepay mobile phone tariff.
