Getting mobile, men are to call another way (6)
I believe the answer is:
rename
'call another way' is the definition.
'getting mobile men are' is the wordplay.
'getting mobile' indicates anagramming the letters.
'men'+'are'='menare'
'menare' anagrammed gives 'RENAME'.
'to' is the link.
(Other definitions for rename that I've seen before include "Give a new title to" , "Meaner (anag.)" , "Brand again" , "Rechristen" , "Confer new appellation of meaner sort" .)
