In Iceland, on a mobile from Scotland (10)

I believe the answer is:

caledonian

I'm a little stuck... Click here to teach me more about this clue!

'scotland' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?

'in iceland on a mobile' is the wordplay.
'mobile' indicates anagramming the letters.
'iceland'+'on'+'a'='icelandona'
'icelandona' is an anagram of 'CALEDONIAN'.

'from' is the link.

Can you help me to learn more?

(Another definition for caledonian that I've seen is " Scots".)

I've seen this clue in The Telegraph.
