Mobile Phone Coverage
Even though Finland has a good mobile phone coverage, there may be dead zones in the national park. Always contact your own operator to check network coverage. In addition, there are always spots where mobile phones do not work or there is interference. If this happens, try climbing to a higher place or going to an open area. You can also try to remove the phone's SIM card for the duration of an emergency call. You should also remember that the coverage is different in different mobile phones.
In Hossa, the mobile phone coverage is fairly good, but there may also be dead zones due to landforms.
Keep your mobile warm. Take food and drinks with you. Some phone models do not function in sub-zero temperatures, so it is worthwhile reporting your route plan and schedule to someone. In order to avoid your mobile battery running dead, take a spare power supply, a spare battery or an old mobile with a working battery with you.
