Phone from abroad: somewhere in Italy, say (4)
I believe the answer is:
roam
'phone from abroad' is the definition.
(roaming can mean using a phone abroad)
'somewhere in italy say' is the wordplay.
'somewhere in italy' becomes 'rome'.
'say' shows a homophone (sound like).
'rome' is a homophone of 'ROAM'.
(Other definitions for roam that I've seen before include "range" , "wander around" , "Travel aimlessly" , "Wander about aimlessly" , "go on walkabout" .)
