Able to move phone (6)
I believe the answer is:
mobile
This clue is a double definition.
'able to move' is the first definition.
(I've seen this before)
'phone' is the second definition.
(mobile phone)
(Other definitions for mobile that I've seen before include "Portable phone" , "Moveable, phone say" , "Able to move freely" , "locomotive" , "Able to move, not fixed" .)
