When I went through Finland I checked several times my mobil telephone. There are 6 operators i Helsinki and out of Helsinki the number of available networks varies from 5 to 3. Automatisk search gave sometimes not optimal operator so if you have mobil telephone of one operator, for example, Telia, than seek FI Telia i Finland. In faktum as for swedish operators in Sweden there is not so big makeup price if one call to tel of another. For example ( I take tariff plan I use) one minute costar i working days Monday-Friday 08.00-18.00 0.6usd ( I transferred to usd from sk), other time 0.03usd. If one call to swedish operators telephone than one’s own there is the same price for working days and plus 0.05 usd per minute in other time. SMS costar about 0.13 usd and MMS (pictures through mobil) costar 0.34-0.44 usd in different tariffplans plus one enjoy free limit of MMS which is different and depends on operator and tariffplan. Unfortunately there is one problem for to decide. Telia, Comviq och Vodafon do not strike a deal about MMS (the same problem as with SMS i Russia between different operators) yet.
