In the second instalment from our exclusive survey: More than 8 out of 10 of us have stored numbers we've never called - who are yours?

We’ve discovered that 85% of us have numbers in our phonebook that we’ve never called. Just like we collect friends on Facebook, it seems our phonebooks are no different.

 “Before it was easy to transfer contacts I used to have a cull of those I never used.”

We can probably all find the contact details of people whose faces we can’t even remember in our phone’s address book. Clearly we are a nation of phone number-hoarders but do we go the extra step of actively taking these redundant numbers with us when we get a new phone? We headed to the streets of London to get people’s reactions.

Andy Waugh, 29 and a business owner from Kew admits it’s just much easier to transfer everything. “Though I have phone numbers that I’ll probably never use nowadays I always take all my old contacts when I get a new phone because it is so easy to do. But before it was easy to transfer contacts I used to have a cull of those I never used.”

However, Ruby Martin, 31, who is an actress from Hampstead, always has a spring clean when she gets a new phone. “Every time I change my phone I never carry over old numbers that I don’t know or ever use,” she says.

We want your stories: How many unused numbers are you hoarding? Whose number have you had for the longest? Let us know.

It’s not just number hoarding the nation is guilty of though. Stay tuned for more fascinating insights into people’s mobile phone habits at blog.vodafone.co.uk/mobilemanners
