Quick means of communication in time abroad (9)
I believe the answer is:
immediate
'quick' is the definition.
(I know that quick can be written as immediate)
'means of communication in time abroad' is the wordplay.
'means of communication' becomes 'media' (mass media).
'in' indicates putting letters inside.
'abroad' indicates an anagram (letters move around or go abroad).
'time' is an anagram of 'imte'.
'media' going into 'imte' is 'IMMEDIATE'.
(Other definitions for immediate that I've seen before include "Instant" , "Prompt, straightaway" , "Present" , "Direct" , "on the spot" .)
