After many years, I have decided to sell my mobile phone number. It contains six 7s, three 8's, one 9. I'm a UK citizen and the number can be transferred to any [unlocked] phone. This is a highly memorable number since the digits sequence logically and rhythmically. So, for instance, it is not something like '07777777719'. This causes problems because in reciting and/or memorising it aurally the number of 7s can be confused. My number, on the other hand, does not contain this problem, since it has structure and logic. 

Only serious offers will be considered and it is common-sensical that your own phone will have to be unlocked, etc., for this one to work. This number is particularly useful for businesses or high-profile persons.
