Finland

Basics
Finland has three national network operators: They are supplemented by the local operator Ålcom on the Åland Islands only. Ålcom works on the mainland also by roaming on the other national networks for no additional charge.
 * Sonera (by TeliaSonera, Tele Finland is a low cost sub-brand of TeliaSonera)
 * Elisa (Saunalahti is a consumer sub-brand of Elisa)
 * DNA (by DNA Oy)

2G is on 900 and 1800 MHz, 3G on 900 and 2100 MHz, 4G/LTE on 800, 1800 and 2600 MHz. In the less populated northern and eastern part Sonera and DNA share one common network.

Elisa has the best coverage and speed in 3G and 4G in the country. Sonera has prepaid on a good network, while DNA as 3rd operator has the most flexible pricing as its own brand and through its resellers and still good coverage in the populated areas. 4G/LTE is open to all prepaid tariffs without surcharge (except where stated).

Finland still offers very cheap data and real unlimited rates similar to the Baltic states.

Sonera (by TeliaSonera)
