This is how you make a call in Finland from a landline telephone to a mobile phone with the area code 0abc:
|0abc + telephone number ||call using the operator providing your subscription
|90XYZ + 0abc + telephone number||call using a general carrier access code (XYZ indicates the telecoms operator)|
To call a Finnish mobile phone from abroad, dial first the Finnish country code 358 and then the mobile network area code without the first zero (0).
For example, if the area code is 0abc dial: +358 abc 123 4567.
A list of the mobile network area codes FICORA has granted to telecoms operators is available here.
