Health
Oman is generally a well-developed destination, but plan for intense heat, sun and dehydration, especially May-Sept and on desert/wadi hikes. Use safe food and water habits; avoid untreated freshwater because schistosomiasis is listed for Oman. Prevent mosquito, tick and sand-fly bites; CDC flags dengue, leishmaniasis and CCHF risks. Avoid contact with stray animals and be cautious around camels/sick people because of rabies/MERS considerations. High-altitude illness is not a typical visitor issue, but mountain routes can be remote and cooler.
Vaccinations
Consult a doctor or travel clinic at least 4-6 weeks before travel. Be up to date on routine vaccines such as MMR, polio, Tdap, flu, varicella and shingles as appropriate, plus COVID-19. CDC recommends hepatitis A for unvaccinated travelers to Oman, hepatitis B for many travelers, and typhoid for most travelers, especially rural/smaller-city or friends-and-relatives stays. Rabies pre-exposure vaccine may be considered for animal-contact or remote trips. Yellow fever vaccine is not recommended for Oman itself, but a certificate is required for travelers aged 9 months+ arriving from, or transiting over 12 hours in, yellow-fever-risk countries, including Rwanda and Tanzania.
eSIM / connectivity
eSIM and 4G/5G mobile data are broadly available in Muscat and major towns, with weaker coverage possible in deserts, wadis and mountains. Main local carriers are Omantel, Ooredoo Oman and Vodafone Oman; prepaid/tourist data options are commonly sold through airport counters, stores and apps where supported. Check that your phone is unlocked and eSIM-compatible, and expect passport/ID registration for local service. Travel eSIM aggregators also cover Oman, but local SIM/eSIM may be better for voice or longer stays.
