I'm getting phone fixed (8)
I believe the answer is:
immobile
'fixed' is the definition.
('immobile' can be similar in meaning to 'fixed')
'i'm getting phone' is the wordplay.
'getting' says to put letters next to each other.
'phone' becomes 'mobile' (I've seen this before).
'im'+'mobile'='IMMOBILE'
(Other definitions for immobile that I've seen before include "Still" , "fixed" , "Unmoving" , "Unable to move" , "Not capable of movement" .)
