Health
Norway has high food/water standards; normal urban tap water and restaurant hygiene are generally good, but use treated water when hiking/camping or if advised locally. Main practical risks are cold exposure and fast-changing mountain/coastal weather, sun/UV on snow or water, ticks in wooded/grass areas, and mosquitoes as a nuisance. No malaria risk is listed by CDC. Check ticks after outdoor activity; seek care for animal bites, especially on Svalbard where wildlife rabies exists.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, influenza, polio, varicella, Tdap and shingles where appropriate, plus COVID-19. Hepatitis A is considered for most travelers; hepatitis B is recommended for unvaccinated travelers under 60 and may be considered for older travelers. Tick-borne encephalitis vaccine is recommended/considered for extensive outdoor exposure in endemic areas. Rabies pre-exposure vaccine depends on animal-contact risk and access to care; dogs are not commonly rabid in mainland Norway, but Svalbard wildlife risk exists. Yellow fever vaccine is not recommended and no certificate is required for Norway.
eSIM / connectivity
eSIM is widely supported by major Norwegian networks. Telia states eSIM works like a physical SIM and supports most eSIM-capable devices; Telia prepaid can use eSIM but may need owner registration/BankID or in-store help if you lack Norwegian ID. Ice sells/activates mobile subscriptions with eSIM through its app and supports common iPhone, Samsung, Pixel and other models. Telenor, Telia and Ice are the main networks; travelers can also use roaming or international travel eSIMs. Check device unlock, EID support, 4G/5G bands, and ID requirements before arrival.
