This weekend I’ve been with the BBC One Rip Off Britain team in Liverpool giving consumer advice and top tips in the show’s pop up shop.

BBC Rip Off Britain Pop Up Shop LiverpoolAs a technology and communications expert for the show I get asked a lot of questions throughout the year about mobile phones, landlines and the internet.

A common theme for many viewers in this year’s pop up shop has been how to deal with nuisance calls; there were also complaints about call charges to 118 directory services numbers, particularly when they offer to connect the call on your behalf.

In a new item for the show I gave a workshop on top tips for using your mobile phone while abroad: Gloria Hunniford and I took to the streets of Liverpool to show how, with a little planning, everybody can safely roam with their phones while avoid a nasty bill shock when they return home.

Season 5 of Rip Off Britain is due to broadcast on BBC One during daytimes in September.
