_Amy's solution below will give you a list of unique mobile numbers but the rest of the rows will contain just the first id, name, area that has that number. I would add count(*) as cnt in the inner query and use select a.*, b.cnt from .. in the outer query - at least that way you'll get positive indication of duplicated numbers

Try this:

SQL

select a.* from mobilecollection a
inner join
(
  select distinct mobileno, min(id) as id from mobilecollection 
  group by mobileno 
) as b
on a.mobileno = b.mobileno
and a.id = b.id
