Cellmapper can measure the frequencies of mobile networks using Samsung's field test mode. This requires root privileges. Rooting removes warranty! After you have root privileges, you enable Read logcat for Samsung Field Test Data from cellmapper's settings. Sonera's and DNA's LTE frequencies are automatically updated on the browsers map so you won't need this feature on their networks. Elisa's LTE is not automatized like this so it requires a rooted Samsung phone to measure. This will not work on custom ROMs. You can "call" the number *#0011# to see the band number. In Finland mainly LTE band 20 (800Mhz) and 3 (1800Mhz) are used.
